Risks Related to Our Company and Our Industry

Volatile market and industry trends, in particular, changes in demand for solar power products and continued downward pressure on the prices of solar power products could reduce our revenues and profitability.

We are affected by solar power market and industry trends. From the fourth quarter of 2008 to the first quarter of 2009, the global solar power industry experienced a precipitous decline in demand. During the same period, the global supply of solar power products exceeded global demand as a result of the global economic downturn. Such oversupply of solar power products contributed to the decline in the average selling price of our solar products, including solar cells and average selling prices of our solar cells.

5

After significant price movements of 2009, relative stability returned to the industry during 2010 mainly due to global economic conditions. However, we expect solar power product prices to decline in the near future due to decreased feed-in-tariffs in most European countries, increases in manufacturing capacity in our industry, reductions in polysilicon cost, and increased production efficiencies. If the prices of our products decline, or we are unable to lower our costs in line with price declines, whether through increasing manufacturing efficiency, securing raw materials at lower costs or technological advances, our revenues and profitability would be materially and adversely affected.

The availability and price of silicon raw materials may affect our gross margins and profitability.

Polysilicon is an essential raw material in our production of solar power products. The procurement costs of silicon wafers and other silicon-based raw materials have accounted for a substantial majority of our cost of revenues since we began our commercial production of solar cells in August 2005.

From early 2007 to the fourth quarter of 2008, mainly due to growing demand for solar power products and limited supply of polysilicon, there was an industry-wide shortage of polysilicon, which resulted in increasing polysilicon price. From late 2008 to the second half of 2009, however, there was an industry-wide excess supply of polysilicon, primarily due to increased supply from both existing polysilicon manufacturers and new entrants and weakened demand from the end market. As a result, polysilicon spot prices fell significantly from late 2008 to the second half of 2009, before stabilizing in 2010.

According to Solarbuzz LLC, or Solarbuzz, an independent solar energy research and consulting firm, the average initial price range of long-term polysilicon supply contracts narrowed to $52 to $57 per kilogram in the fourth quarter of 2010 from $50 to $60 per kilogram in the fourth quarter of 2009, and the spot price for solar grade polysilicon maintained a level of around $55 per kilogram by the beginning of 2010 compared to the prices of $45 to $65 per kilogram in the fourth quarter of 2009, but spiked dramatically to above $65 per kilogram by the end of third quarter of 2010, and further increased to $80 per kilogram in the fourth quarter of 2010. Spot price softened to around $70 per kilogram by the end of the first quarter of 2011, according to Solarbuzz.

Increases in the price of polysilicon have in the past resulted in increases in the price of wafers, and these increases in the price of silicon raw materials have in the past increased our production costs. Due to the volatile market prices, we cannot assure you that the price of polysilicon will remain at its current levels, especially when the global solar power market regains its growth momentum. Moreover, if the industry-wide shortage of polysilicon happens again, we may experience late or non-delivery from suppliers and purchase silicon raw materials of lower grade quality that may result in lower conversion efficiencies and reduce our average selling prices and revenues.

Our strategy of expanding into downstream solar power businesses may not be as successful as we envisioned.

On November 1, 2010, we completed the acquisition of SST and NRE, both of which were our related parties at the time of such transactions, from China Electric Equipment Group Co., Ltd., or CEEG, an entity controlled by Mr. Tingxiu Lu, and Sundex Holdings Limited, a company not affiliated with us, for total consideration of approximately RMB308.0 million ($46.0 million). SST and NRE integrate the research and development, production, sales and servicing of solar modules, with total annual production capacities of 480MW as of December 31, 2010. The acquisitions facilitate the implementation of our strategy to expand into downstream solar power businesses, including the solar module business. The acquisitions and our implementation of the strategy of expanding into downstream solar power businesses resulted in substantial changes to our business, including, among others, the change in our customer base, from primarily module manufacturers and system integrators purchasing solar cells to primarily system integrators, solar power project developers and solar power product distributors. We have limited experience engaging in the solar module businesses and may not be successful in establishing a strong reputation in the market. Moreover, this sector of the solar power industry is rapidly evolving and is becoming increasingly competitive. We cannot predict whether, or how quickly, this market will grow.

6

Our successful expansion into the solar module business depends on a number of factors, including: the level of demand for solar modules services; our ability to provide solar modules services with quality satisfactory to our customers; our ability to hire and retain staff with relevant experience in this business; our ability to compete effectively with other companies engaging in similar businesses; our ability to maintain and develop relationships with solar module services customers, including existing customers of the companies we acquired; our ability to offer module products services in countries presenting cultural, language, regulatory or other barriers; our ability to adapt and develop our products and services according to market conditions and needs; and our ability to integrate the companies we acquired. If we fail to successfully expand our solar module business, our growth strategy will be impaired. We may fail to recoup our investment, and our business, competitiveness and results of operations could be materially and adversely affected.

Significant reductions in feed-in tariffs and other forms of government subsidies and economic incentives for solar power applications may cause demand for our products and our revenues to decline.

We believe that the near-term growth of the solar power market depends in large part on the availability and size of government subsidies and economic incentives. The reduction or elimination of subsidies and economic incentives may adversely affect the growth of this market or result in increased price competition, either of which could cause our revenues to decline.

Today, when upfront system costs are factored into costs per kilowatt, the cost of solar power substantially exceeds the cost of power furnished by the electric utility grid in almost all locations. As a result, national and local governmental bodies in many countries, most notably in China, Germany, Italy, Spain, France and the United States, have provided subsidies and economic incentives in the form of feed-in tariffs, rebates, tax credits and other incentives to distributors, system integrators and manufacturers of solar power products in order to promote the use of solar energy in on-grid applications and to reduce dependence on other forms of energy.

As the solar power industry continues to develop, policy shifts could reduce or eliminate these government economic incentives altogether. For example, in 2009 and 2010, Germany’s government reduced the country’s solar energy feed-in tariffs. Germany’s government indicated in the beginning of 2011 they expect to further decrease solar power subsidies by up to 15% this year as demand for solar power panels continue to thrive in the country. The reduction in government incentives to users of solar power products in Germany may materially and adversely impact the German solar market if such measures are not implemented prudently, which may in turn materially and adversely affect our direct or indirect sales into Germany. In 2010, Italy’s government also announced annual reductions to feed-in tariffs starting from 2011 in an effort to impede overheating of its solar market. In Spain, since 2009, continued reductions in feed-in tariff as a result of the government’s spending cut backs have resulted in a weakened solar power industry.

We export a large amount of our products to Germany, Italy, Eastern Europe and France; and, other than European market, we also expect to sell more products to the US, China and emerging markets as we expand into the downstream solar power business.

There have been suggestions that the European Union may seek to initiate anti-dumping investigations regarding imports of solar power products from China. If the European Union initiates anti-dumping investigation against Chinese exporters or imposes anti-dumping measures, including tariffs on solar power product imports from China, our business and results of operation could be materially and adversely affected. Reductions in, or eliminations of, subsidies and economic incentives for on-grid solar energy applications could result in decreased demand for our products and cause our revenues to decline.

We have a limited operating history and we have incurred losses in certain prior periods and may incur losses in the future.

We incurred net losses of $23.3 million and $10.3 million in 2008 and 2009, respectively. Although we had net income of $51.7 million in 2010, we cannot assure you that we will not incur net losses in the future or that there will not be any earnings or our revenue will not decline in any future periods. Our ability to maintain profitability depends on, among others, the growth rate of the solar power market, the continued global market acceptance of solar power products in general and our existing and future products in particular, our ability to secure quality raw materials, primarily silicon wafers, the pricing trend of solar power products,

7

the competitiveness of our technology and products as well as our ability to provide new products to meet the demands of our customers, our ability to achieve our manufacturing expansion plans and our ability to control our costs and expenses. We may not be able to achieve or sustain profitability on a quarterly or annual basis.

Furthermore, our limited operating history may not provide a meaningful basis for evaluating our business, financial performance and prospects. Accordingly, even though we achieved growth or profitability during certain prior periods, you should not rely on our results of operations for any prior periods as an indication of our future performance. You should consider our business and prospects in light of the risks, expenses and challenges that we have as a company with a limited operating history seeking to develop and manufacture new products in a rapidly evolving market.

Our dependence on a limited number of third-party suppliers for key raw materials and solar cells and customized manufacturing equipment could prevent us from timely delivering our products to our customers in the required quantities, which could result in order cancellations and decreased revenue.

We purchase silicon raw materials and some of the solar cells used in our module manufacturing business from a limited number of third-party suppliers. Our top ten suppliers for our solar cell business supplied approximately 53.6% of the supplies we procured for our solar cell manufacturing in 2010. The solar cells manufactured by us accounted for approximately 86% of the supplies we procured for our module business in the last two months in 2010. We expect to purchase raw materials and some of the solar cells we need for our module business from outside suppliers in 2011. Most of our supply contracts have terms of less than one year. If we fail to develop or maintain our relationships with major suppliers of silicon raw materials or solar cells, we may be unable to manufacture our products or our products may only be available at a higher cost or after a long delay, and we could be prevented from delivering our products to our customers in the required quantities and at prices that are profitable. Problems of this kind could cause order cancellations and loss of market share. Historically, we encountered problems with respect to the quality of silicon raw material supplied by some of our suppliers, which resulted in lower conversion efficiencies of our solar cells. Some of our suppliers failed to perform their delivery obligations in 2010 because of volatile market prices. In addition, historically, many of our contracts for silicon raw material supply did not provide for a remedy for non-delivery beyond a refund of any advance payment that we may have made, and our legal recourse in cases of non-delivery may be limited.

The failure of any major supplier to supply raw materials that meet our quality, quantity and cost requirements in a timely manner could impair our ability to manufacture our products and could increase our costs, particularly if we are unable to obtain these materials and components from alternative sources on a timely basis or on commercially reasonable terms. The pricing terms under our raw material supply framework agreements generally are to be determined based on future negotiations. If we cannot agree on pricing terms with those suppliers in the future, those agreements will not be enforceable and we would then need to seek alternative supplies. In such an event, we may not be able to secure sufficient alternative supplies.

In addition, certain of our cell manufacturing equipment has been designed and made specifically for us. As a result, such equipment is not readily available from multiple vendors and would be difficult to repair or replace. Any significant damage to, or breakdown of, our customized manufacturing equipment could cause material interruptions to our operations and consequentially could have a material adverse effect on our business and results of operations.

Difficult global economic conditions and credit environment may adversely affect the demand for our products.

The demand for solar power products is influenced by macroeconomic factors, such as global economic conditions, the supply and price of other energy products, as well as government regulations and policies concerning the electric utility industry. The global financial markets experienced a downturn in 2008, and since most of the world’s major economies have experienced a period of slow economic growth. The global economic downturn resulted in weakened market demand for products that require significant initial capital expenditures, including solar power products. The global economic downturn in several key solar power markets resulted in fewer investments in new installation projects that make use of solar power products. Existing projects may also be delayed as a result of the credit and other disruptions. The unfavorable credit

8

environment, which affects the ability of sponsors to obtain financing for their projects, also contributed to the slowdown of the large solar project market segment. Furthermore, a decrease in the price of other energy products, such as oil, coal and natural gas, could reduce demand for alternative forms of energy, such as solar energy and may reduce the urgency of the market to invest in alternative energy. These macroeconomic factors resulted in reduced demand for our solar power products, and adversely affected our operating results. In 2008, 2009 and 2010, partly due to the impact of global financial market disruption and economic slowdown, some of our customers cancelled or delayed orders for our products.

Overall global economic conditions and the credit environment have improved significantly from the second half of 2009. However, if these macroeconomic factors deteriorate again, the demand for our products will be materially and adversely affected.

Our costs and expenses may increase as a result of entering into fixed price, firm purchase commitment arrangements with our suppliers.

In response to the industry-wide shortage of silicon raw materials prior to the third quarter of 2008, we purchased silicon raw materials using short-term and long-term contracts from a limited number of international and domestic suppliers. Currently we use both short-term and long-term contracts to secure our silicon raw materials supply, and the long-term contracts accounted for approximately 9.0% of all the silicon raw materials that we purchased in 2010. Some agreements provide for firm purchase commitments and fixed pricing or pricing adjustable within a relatively small range. From the fourth quarter of 2008 to mid-2009, the price of silicon raw materials decreased precipitously because of the excess supply of silicon raw materials resulting from slower global solar power market growth. In light of such excess supply, we have sought to re-negotiate with our long-term supply partner in regard to a long-term supply contract signed in 2008. See “— We have been a party in several legal proceedings, which, if determined adversely, could negatively affect our business and results of operations.” If we fail to re-negotiate or terminate any similar contracts in the future, we may be subject to contractual damages. If the prices under our amended supply contracts continue to be higher than the market prices after such re-negotiation, we may be placed at a competitive disadvantage versus our competitors, and our profitability could decline. In addition, if demand for our solar power products decreases and such agreements require us to purchase more raw materials than are required to meet our demand, we may incur costs associated with carrying excess inventory, which may have a material adverse effect on our cash flows. To the extent we are not able to pass these increased costs and expenses on to our customers, our business, financial condition and results of operations may be materially and adversely affected.

We have significant outstanding bank borrowings, and we may not be able to arrange adequate financing when they mature or may encounter other difficulties in maintaining liquidity.

As of December 31, 2010, we had $106.5 million in cash and cash equivalents, and we had $169.7 million in outstanding borrowings. Except for a long-term loan of approximately $30.2 million which becomes due in October 2012, all of our outstanding borrowings as of December 31, 2010 become due within one year. In the first quarter of 2011, we borrowed additional amounts and repaid some of our loans, and all of the amounts we borrowed in the first quarter of 2011 will become due within one year of the date of this report.

The amount of our borrowings could constrain our operational flexibility, including requiring a substantial portion of our cash flows to be set aside to service our debt obligations, increasing our exposure to interest rate fluctuations and limiting our ability to obtain additional financing. Furthermore, the PRC government may pass measures to tighten credit, including trade financing, available in the PRC market. Any future turmoil in the global credit markets and the subsequent impact on the liquidity of financial institutions may adversely affect our ability to fund our business through borrowings, under either existing or newly created instruments in the public or private markets on terms that we believe to be reasonable, if at all. We cannot assure you that we will be able to obtain extensions of our facilities as they mature. If we are unable to obtain extensions of these facilities, or if we are unable to obtain sufficient alternative funding on reasonable terms to make repayments, we will have to repay these borrowings with cash generated by our operating activities. We cannot assure you that our business will generate sufficient cash flows from operations to repay these borrowings. In addition, repaying these borrowings with cash generated by our operating activities will divert our financial resources from the requirements of our ongoing operations and future growth.

9

Historically, given the state of the industry, we generally need to make prepayments at a certain percentage of the order value to our suppliers of silicon raw materials in advance of shipment. Due to the relative oversupply of polysilicon, prepayment as a percentage of the entire contract has been reducing. In 2010, most of our suppliers granted us credit terms under their contracts with us. However, our purchases of raw materials may continue to require us to make certain working capital commitments. We may also need additional capital for the expansion and modification of our manufacturing lines in the future. As a result, we may require additional debt or equity financing. Furthermore, we have granted credit terms for our sales to some of our large customers. Some of our customers may fail to meet their payment obligations, which would materially and adversely affect our financial position, liquidity and results of operations.

In addition, we may also need a significant amount of cash to meet future capital requirements in connection with our overall expansion plan, including the expansion of our solar power product manufacturing facilities, as well as research and development activities in order to remain competitive. Future acquisitions, expansions, market changes or other developments may also require additional funds. If we fail to effectively manage our cash flows from operations, borrowings and equity contributions to support our cash flow requirements, we may encounter difficulty in maintaining our liquidity, which would have a material adverse effect on our business, financial condition and future prospects.

Our advance payments to most of our raw material suppliers expose us to the credit risk of these suppliers, and if these suppliers default in delivery or refunding the payment, our financial condition, results of operations and liquidity may be adversely affected.

Under the supply contracts with most of our silicon raw material suppliers entered into during an industry-wide shortage of silicon raw materials in the past few years, we made prepayments to our suppliers as incentives prior to the scheduled delivery dates for silicon raw materials. Due to increased supply of silicon raw materials since the fourth quarter of 2008, we reduced such prepayments and our advances to suppliers decreased significantly from $7.3 million as of December 31, 2008 to $0.2 million as of December 31, 2009. However, our prepayments increased to $8.5 million as of December 31, 2010 as we increased the prepayment in some of our contracts in order to maintain our relationship and preferential price with qualified suppliers.

In addition, we depend on a limited number of suppliers and we may continue to be required to make such advance payments without receiving collateral in the future. As a result, our claims for such advance payments would rank only as unsecured claims, exposing us to the credit risks of the suppliers in the event of their insolvency or bankruptcy. We may not be able to recover such advance payments and would suffer losses should the suppliers fail to fulfill their delivery obligations under the contracts.

Our dependence on a limited number of customers may cause significant fluctuations or declines in our revenues.

We currently sell a substantial portion of our solar power products to a limited number of customers. In 2010, major customers of our solar cell business included NRE, SST, ILB HELIOS SPAIN, S.A., Solaire Direct Technologies, and asola Advanced and Automotive Solar Systems GmbH. In 2010, major customers of our solar module business included Ecoware S.p.A. (Gruppo Kerself), P.M.service s.r.l, TENERGIE, CEEG Nanjing International Trade Co., Ltd. and CEEG (Nanjing) Solar Research Institute. Our top five customers contributed over 57.7% of our net revenues in 2010, including SST and NRE, both of which we acquired on November 1, 2010, and together they contributed approximately 46.8% of our net revenues in 2010 prior to the acquisition. In 2008, 2009 and 2010, non-related party customers contributing 10% or more of our total net revenues accounted for approximately 33%, 11% and nil of our total net revenues, respectively. The decrease in percentage in 2010 was due to our strategy to sell our solar cells to SST and NRE which we acquired in November 2010, upon our expansion into the downstream solar power business.

After the completion of our acquisitions of SST and NRE, our customer base has substantially changed from primarily module manufacturers and system integrators to primarily a limited number of distributors, system integrators and various manufacturers who either integrate our products into their own products or sell them as part of their product portfolio. We anticipate that we will continue to depend on a limited number of customers for our module business in the foreseeable future. We have competitors who may have stronger relationships or may enter into exclusive relationships with some of the key distributors or system integrators

10

to whom we sell our products. As a result, they may be able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of their products than we can.

The loss of one or more of our significant customers and reduced or cancelled orders from one or more of our significant customers may cause material fluctuations or declines in our revenues.

We anticipate that our dependence on a limited number of customers will continue in the foreseeable future. Consequently, any one of the following events may cause material fluctuations or declines in our revenues:

• reduction, delay or cancellation of orders from one or more of our significant customers;

• loss of one or more of our significant customers and our failure to identify additional or replacement customers; and

• failure of any of our significant customers to make timely payment for our products.

The practice of requiring customers to make advance payments when they place orders with us has declined, and we have experienced and will continue to experience increased needs to finance our working capital requirements and are exposed to increased credit risk of our customers.

We historically required our customers to make an advance payment of a certain percentage of their orders, a business practice that helped us to manage our accounts receivable, prepay our suppliers and reduce the amount of funds that we needed to finance our working capital requirements. In line with market trends, this practice has declined, and has resulted in our increased need to obtain additional short-term borrowings to fund our current cash requirements. Furthermore, a larger portion of our revenues have been and may continue to be, derived from credits sales to our customers. Failure to timely collect our receivables may adversely affect our cash flows. In 2011, we believe a majority of our revenues will be derived from credit sales, generally with payment schedules according to negotiated contracts. As a result of the disruptions in the financial markets and other macro-economic challenges which had affected the world economy, our customers may experience cash flow concerns. As a result, they may delay their payment to us. Any inability of current or potential customers to pay us may adversely affect our earnings and cash flow.

If we are unable to maintain a high utilization rate of our manufacturing capacity, our operating margins may decline substantially.

Our ability to achieve profitability depends in part on our ability to maintain a high utilization rate of our manufacturing capacity. With the slowed growth of the solar power market, it is more difficult for us to obtain enough orders for the solar power products that we are capable of producing. If we are unable to obtain sufficient orders for our products, procure sufficient raw materials, or if we experience any material equipment failure, then we will not be able to maintain a high utilization rate of our manufacturing capacity. As we incur fixed costs associated with our facilities and equipment whether they are being utilized, operating at less than full utilization results in expenses without corresponding revenue, which may reduce our operating margins.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than we do, we may not be able to compete successfully and we may lose or be unable to gain market share.

The market for solar power products is highly competitive and continually evolving. We expect to face increased competition, which may result in price reductions, reduced margins or loss of market share. Our competitors include specialized power product manufacturers such as Sunpower Corp, Suntech Power Holdings Co., Ltd., Sharp Corporation, Trina Solar Ltd,. Yingli Green Energy Holding Co., Ltd., Canadian Solar Inc., Hanwha SolarOne Ltd., and Jinko Solar Holding Co., Ltd. Some of our competitors, for example Yingli Green Energy Holding Co., Ltd., have also become vertically integrated, from polysilicon, wafer and module manufacturing to solar system integration. During periods of raw material supply shortage, their internally produced raw materials may enable them to realize a higher margin in comparison with other solar power product manufacturers.

11

Increases in polysilicon prices and solar power product manufacturing capacity could result in substantial downward pressure on the price of solar power products and intensify competition in 2011. We may also face new competition from semiconductor manufacturers, several of which have already announced their intention to start production of solar power products. In addition, the entire solar power industry faces competition from conventional and non-solar renewable energy technologies. Due to relatively high manufacturing costs compared to most other energy sources, solar energy is generally not competitive without government subsidies and economic incentives.

Many of our existing and potential competitors have substantially greater financial, technical, manufacturing and other resources than we do. Their greater size in some cases provides them with a competitive advantage with respect to manufacturing costs due to their economies of scale and their ability to purchase raw materials at lower prices. Many of our competitors also have more established distribution networks and larger customer bases. In addition, they have well-established relationships with our customers and have extensive knowledge of our target markets. As a result, they may be able to devote greater resources to the research, development, promotion and sale of their products or respond more quickly to evolving industry standards and changes in market conditions than we can. It is possible that new competitors or alliances among existing competitors will emerge and rapidly acquire significant market share, which would harm our business. If we fail to compete successfully, our business would suffer and we may lose or be unable to gain market share.

If solar power technology is not suitable for widespread adoption, or if sufficient demand for solar power products does not develop or takes longer to develop than we anticipate, our revenues may not continue to increase or may decline, and we may be unable to achieve or sustain our profitability.

The solar power market is at a relatively early stage of development, and the extent of acceptance of solar power products is uncertain. Historical and current market data on the solar power industry are not as readily available as those for other more established industries where trends can be assessed more reliably from data gathered over a longer period of time. In addition, demand for solar power products may not develop or may develop to a lesser extent than we anticipate. Many factors may affect the viability of widespread adoption of solar power technology and demand for solar power products, including:

• cost-effectiveness, performance and reliability of solar power products compared to conventional and other renewable energy sources and products;

• success of other alternative energy generation technologies, such as wind power, hydroelectric power and biomass;

• fluctuations in economic and market conditions that affect the viability of conventional and other renewable energy sources, such as increases or decreases in the prices of oil and other fossil fuels or decreases in capital expenditures by end users of solar power products;

• availability of government subsidies and incentives to support the development of the solar power industry;

• capital expenditures by end users of solar power products, which tend to decrease when the economy slows down; and

• deregulation of the electric power industry and the broader energy industry.

If solar power technology is not viable for widespread adoption or sufficient demand for solar power products does not develop or develops to a lesser extent than we anticipate, our revenues may suffer and we may be unable to sustain our profitability.

Advances in solar power technology could render our products uncompetitive or obsolete, which could reduce our market share and cause our sales and profits to decline.

The solar power market is characterized by evolving technological standards that require improved features, such as higher conversion efficiencies and higher power output. This requires us to develop new solar power products and enhancements for existing solar power products to keep pace with evolving industry standards and changing customer requirements. For example, currently we are focused on crystalline silicon

12

technology and the expansion of production capacity based on crystalline silicon, which today is the primary technology used by most solar cell and module manufacturers. Some overseas producers have developed alternative forms of solar power technologies, such as thin-film technologies. Failure to further refine our technology and to develop and introduce new solar power products could cause our products to become uncompetitive or obsolete, which could reduce our market share and cause our revenues to decline. We will need to invest significant financial resources in research and development to maintain our market position, keep pace with technological advances in the solar power industry and effectively compete in the future.

If our future innovations fail to enable us to maintain or improve our competitive position, we may lose market share. If we are unable to successfully design, develop and bring to market competitive new solar power products or enhance our existing solar power products, we may not be able to compete successfully. Competing solar power technologies may have lower manufacturing costs or higher product performance than those expected from our solar power products. In addition, if we, or our customers, are unable to manage product transitions, our business and results of operations would be negatively affected.

We may not be successful in the commercial production of Quasar solar cells or other new products, which could limit our growth prospects.

We are currently developing technology for manufacturing Quasar solar cells. The conversion efficiency of this new type of solar cells may be generally higher than that of mainstream P-type solar cells. However, we cannot assure you that we will be able to commercially manufacture Quasar solar cells on a large scale in a cost effective way.

We may face significant challenges in manufacturing Quasar solar cells. Minor deviations in the manufacturing process can cause decreases in yield and cell conversion efficiencies. We may face difficulty in securing wafer supply for the manufacture of this new type of solar cells. If we are unable to commence manufacturing this new type of solar cells on a timely basis, or if we face technological difficulties in cost-efficiently producing this new type of solar cells with the expected performance on a stable level, or if we are unable to secure sufficient raw material supplies or generate sufficient customer demand for this new type of solar cells, our business and prospects may be adversely impacted.

We may also have difficulty in converting existing manufacturing lines or installing new manufacturing lines for the production of new products. These difficulties could arise from a number of reasons, including difficulties or delays in obtaining or installing equipment, adapting our production to new processes or training our personnel. We may also have difficulties in achieving the higher conversion efficiencies that we expect to achieve with these new products. Any of these difficulties may adversely affect our business, results of operations and financial condition.

Our future success substantially depends on our ability to increase both our manufacturing capacity and total output, which exposes us to a number of risks and uncertainties.

We have 13 solar cell manufacturing lines, with an aggregate annual production capacity of 404 MW, assuming the use of 156-millimeter monocrystalline silicon wafers, and an annual module production capacity of 480 MW, as of December 31, 2010. Our future success partially depend on our ability to increase both our manufacturing capacity and total output. If we are unable to do so, we may be unable to expand our business, decrease our costs per watt, maintain our competitive position and improve our profitability. Our ability to establish additional manufacturing capacity and increase output is subject to significant risks and uncertainties, including:

• the need to raise significant additional funds, which we may be unable to obtain on commercially viable terms or at all, to purchase raw materials and to build additional manufacturing facilities;

• delays and cost overruns as a result of a number of factors, many of which are beyond our control, such as increases in the price of silicon raw materials and problems with equipment vendors;

• delays or denial of required approvals by relevant government authorities;

• diversion of significant management attention;

13

• the ability to secure sufficient silicon raw materials, primarily silicon wafers, to support our expanded manufacturing capacity; and

• the recovery of global economy and demand for solar power products in overseas markets as influenced by the global economic downturn and its effects.

If we are unable to establish or successfully operate additional manufacturing capacity, or if we encounter any of the risks described above, we may be unable to expand our business as planned. Moreover, we cannot assure you that if we do expand our manufacturing capacity as planned, we will be able to generate sufficient customer demand for our solar power products to support our increased production levels.

We may experience difficulty in achieving acceptable yields and product performance as a result of manufacturing problems, which could negatively impact our future revenue.

The technology for the manufacture of solar power products is highly complex and is continually being modified in an effort to improve yields and product performance. The quality of the raw materials used, microscopic impurities such as dust and other contaminants, difficulties in the manufacturing process, or malfunctions of the equipment or facilities used can lower yields, cause quality control problems, interrupt production or result in losses of products in process.

Because our existing manufacturing capabilities are, and our future manufacturing capabilities will likely remain, concentrated in our manufacturing facilities in Nanjing and Shanghai, China, any problem in our facilities may limit our ability to manufacture products. We may encounter problems in our manufacturing facilities as a result of, among other things, production failures, construction delays, human errors, equipment malfunction or process contamination, which could seriously harm our operations. We may also experience floods, droughts, power losses and similar events beyond our control that would affect our facilities. For example, the unusually heavy snowstorms in the first quarter of 2008 disrupted our power supply and forced us to suspend our manufacturing operations for three weeks. In addition, a power loss to our Nanjing facility in February 2011 disrupted our entire manufacturing operation for three days, and continuously influenced part of our manufacturing operation for another three days, resulting in a total loss of production capacity of approximately 3.5MW. Any disruption in our manufacturing process that forces us to shut down and restart our production causes a drop-off in production quality during the first two or three weeks after we resume production, which in turn reduces our yield as more of our output falls below our quality control standards during that period.

Our business depends substantially on the continuing efforts of our chairman, executive officers and key employees, and our business may be severely disrupted if we lose their services.

Our future success depends substantially on the continued services of Mr. Tingxiu Lu, our chairman, our executive officers and key employees, especially Dr. Jianhua Zhao, our vice chairman and chief technology officer, Mr. Stephen Zhifang Cai, our director and chief executive officer, and Dr. Aihua Wang, our vice president. In the past, certain of our executive officers and key employees resigned from their positions. For example, Mr. Ruennsheng Allen Wang resigned from the position as our director and chief executive officer in March 2010. Mr. Siegfried Yi Chou Hsu resigned from the position as our chief financial officer in October 2010. We subsequently appointed Mr. Stephen Zhifang Cai as our chief executive officer and director in March and April 2010, respectively, and appointed Mr. Yongfei Chen as our acting chief financial officer in November 2010, respectively. Although we have successfully found replacements for these vacated positions in the past, we cannot assure you that we will continue to be able to find eligible candidates in the future if one or more of our executive officers or key employees are unable or unwilling to continue in their present positions.

Although we believe that these changes of our management team did not materially affect our business operations in the past, if we lose the services of our executive officers or key employees due to their resignation, non-compliance with applicable law or any other reason in the future, especially if we cannot timely find replacements, our business may be severely disrupted, our financial conditions and results of operations may be materially and adversely affected and we may incur additional expenses to recruit, train and retain personnel. If any of our executive officers or key employees joins a competitor or forms a competing company, we may lose customers, suppliers, know-how and key professionals and staff members. Each of our

14

executive officers and key employees has entered into an employment agreement with us which contains non-competition provisions. However, if any dispute arises between our executive officers or our key employees and us, these agreements may not be enforceable in China, where these executive officers or our key employees reside, in light of the uncertainties with China’s legal system. See “— Risks Related to Doing Business in China — Uncertainties with respect to the Chinese legal system could have a material adverse effect on us.”

If we fail to manage our growth and expansion effectively, our business may be adversely affected.

We have experienced a period of rapid growth and expansion that has placed, and continues to place, significant strain on our management personnel, systems and resources. To accommodate our growth, we anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including improvements to our accounting and other internal management systems, all of which require substantial management efforts. We also will need to continue to expand, train, manage and motivate our workforce, manage our customer relationships and manage our relationships with raw material suppliers. All of these endeavors will require substantial management effort and skill and the incurrence of additional expenditures. If we fail to manage our growth effectively, that failure may have a material adverse effect on our business.

Future acquisitions may have an adverse effect on our ability to manage our business.

If we are presented with appropriate opportunities, we may acquire technologies, businesses or assets that are complementary to our business. For example, in November 2010, we completed the acquisition of SST and NRE. These and any future acquisitions may expose us to potential risks, including risks associated with the assimilation of new personnel, unforeseen or hidden liabilities, the diversion of management attention and resources from our existing business and the inability to generate sufficient revenues to offset the costs and expenses of acquisitions. Any difficulties encountered in the acquisition and integration process may have an adverse effect on our ability to manage our business.

We face risks associated with the marketing, distribution and sale of our solar power products internationally, and if we are unable to effectively manage these risks, they could impair our ability to expand our business abroad.

In 2010, we derived 36.1%of our net revenues from sales of our products to customers outside of China. We intend to continue to expand our sales in Europe as well as in other overseas markets such as Italy, Germany, France, Belgium, Eastern Europe, United States, India, Australia and other countries and regions. We anticipate that the majority of our solar module products will be sold to customers outside of China in 2011. The marketing, distribution and sale of our solar power products in the international markets expose us to a number of risks, including:

• fluctuations in currency exchange rates;

• increased costs associated with maintaining marketing efforts in various countries;

• difficulty and costs relating to compliance with the different commercial and legal requirements of the overseas markets in which we offer our products;

• difficulty in engaging and retaining sales personnel who are knowledgeable about, and can function effectively in, overseas markets;

• trade barriers such as export requirements, tariffs, taxes and other restrictions and expenses, which could increase the prices of our products and make us less competitive in some countries; and

• demand for solar power products in overseas markets as influenced by world wide credit crisis and its effects.

15

If we are unable to attract, train and retain qualified personnel, our business may be materially and adversely affected.

Our future success depends, to a significant extent, on our ability to attract, train and retain qualified personnel, particularly technical personnel with expertise in the solar power industry. Since our industry is characterized by high demand and intense competition for talent, there can be no assurance that we will be able to attract or retain the qualified technical staff or other highly- skilled employees that we will need to achieve our strategic objectives. As we are still a relatively young company and our business has grown rapidly, our ability to train and integrate new employees into our operations may not meet the growing demands of our business. If we are unable to attract and retain qualified personnel, our business may be materially and adversely affected.

We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.

Our success depends largely on our ability to use and develop our technology and know-how without infringing the intellectual property rights of third parties. The validity and scope of claims relating to solar power technology patents involve complex scientific, legal and factual questions and analysis and, therefore, may be highly uncertain. We may be subject to litigation involving claims of patent infringement or violation of other intellectual property rights of third parties. The defense and prosecution of intellectual property suits, patent opposition proceedings and related legal and administrative proceedings can be both costly and time-consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we may become a party could subject us to significant liability to third parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our products, or subject us to injunctions prohibiting the manufacture and sale of our products or the use of our technologies. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation.

Failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.

We rely primarily on trade secrets, patent laws and other contractual restrictions to protect our intellectual property. Nevertheless, these afford only limited protection, and the actions we take to protect our intellectual property rights may not be adequate to provide us with meaningful protection or commercial advantage. For example, as of the date of this annual report, we have 23 patents and 24 pending patent applications in China, including patents and patent applications held by our newly acquired module manufacturers. We cannot assure you that in a legal proceeding the claims of our patents would be found valid or that the claims would be interpreted as having sufficient scope to protect the technology we consider important to our business, nor can we assure you that our patent applications will eventually issue with claims of sufficient scope to protect additional technology significant to our business. As a result, we may be unable to exclude third parties from using the technologies that we have developed and compete with us, which could have a material adverse effect on our business, financial condition or operating results.

In addition, litigation may be necessary to enforce our intellectual property rights. We cannot assure you that the outcome of such potential litigation will be in our favor. Such litigation may be costly and may divert management attention as well as divert other resources away from our business. In addition, we have no insurance coverage against litigation costs and would have to bear all costs arising from such litigation to the extent we are unable to recover them from other parties. The occurrence of any of the foregoing could have a material adverse effect on our business, results of operations and financial condition.

Changes to existing regulations and policies may present technical, regulatory and economic barriers to the purchase and use of solar power products, which may significantly reduce demand for our products.

The market for electricity generation products is heavily influenced by government regulations and policies concerning the electric utility industry, as well as policies adopted by electric utilities. These regulations and policies often relate to electricity pricing and technical requirements regarding the interconnection between customer-owned electricity generation and the grid. In a number of countries, these

16

regulations and policies are being modified and may continue to be modified. Customer purchases of, or further investment in the research and development of, alternative energy sources, including solar power technology, could be deterred by these regulations and policies, which could result in a significant reduction in the potential demand for our products. For example, without a regulatory mandated exception for solar power systems, utility customers are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to customers of using our solar power products and make them less desirable, thereby harming our business, prospects, results of operations and financial condition.

We anticipate that our products and their installation will be subject to oversight and regulation in accordance with national and local regulations relating to building codes, safety, environmental protection, utility interconnection and metering and related matters. It is difficult to track the requirements of individual jurisdictions and to design products that comply with the varying standards. Any new government regulations or utility policies pertaining to our solar power products may result in significant additional expenses to us or cause a significant reduction in demand for our solar power products.

Heightened environmental concerns and increased awareness of climate change risks associated with fossil fuel-based power generation have generated political momentum in many governments, which subsequently implemented strategies aimed at the reduction of emissions of carbon dioxide and certain other gases commonly referred to as “greenhouse gases.” Renewable energy sources such as solar power help address these environmental concerns, and governments around the world have implemented a variety of policy initiatives to accelerate the development and adoption of solar power. While passage of climate change legislation or other regulatory initiatives that regulate or restrict emissions of greenhouse gases may encourage use of solar power and accordingly increase demand for our products and services, this could cause us to incur additional direct costs in complying with any new environmental regulations during our manufacturing and research and development processes, as well as increased indirect costs resulting from our customers, suppliers or both incurring additional compliance costs which are subsequently passed on to us.

Fluctuations in exchange rates could adversely affect our business.

The value of the Renminbi against the U.S. dollar, Euro and other currencies is affected by, among other things, changes in China’s political and economic conditions and China’s foreign exchange policies. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi was permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy caused the Renminbi to appreciate approximately 21.5% against the U.S. dollar over the following three years. Since reaching a high against the U.S. dollar in July 2008, however, the Renminbi has traded within a narrow band against the U.S. dollar, remaining within approximately 1% of its August 2008 high. As a consequence, the Renminbi has fluctuated sharply since July 2008 against other freely traded currencies, in tandem with the U.S. dollar. For example, the Renminbi appreciated approximately 27% against the Euro between July 2008 and November 2008. It is difficult to predict how long the current situation may last and when and how it may change again.

A major portion of our sales before our acquisition of module business were denominated in Renminbi and Euros, with the remainder in U.S. dollars, and are denominated in Euros and U.S. dollars after our acquisition of module business, while a substantial portion of our costs and expenses is denominated in Renminbi and U.S. dollars, with the remainder in Euros. Fluctuations in exchange rates, particularly among the U.S. dollars, Renminbi and Euros, may affect our net profit margins and could result in fluctuations in foreign currency exchange and operating gains and losses. We incurred a net foreign exchange loss of approximately $5.1 million in 2010. We cannot predict the impact of future exchange rate fluctuations on our results of operations and may incur net foreign currency losses in the future. In addition, as we rely entirely on dividends paid to us by our operating subsidiaries in China, any significant revaluation of the Renminbi may have a material adverse effect on our revenues and financial condition, and the value of, and any dividends payable on, our ordinary shares and ADSs. For example, to the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our common shares or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect

17

on the U.S. dollar amount available to us. Furthermore, due to the fact that we are paid in Euros for a proportion of our sales, fluctuations in the exchange rate between the Euro and the RMB may also have a material effect on our results of operations.

Noncompliance with present or future construction and environmental regulations may result in potentially significant monetary damages and fines.

In the past, we had begun operating facilities without having obtained all the necessary approvals on the completion acceptance of our certain facilities from relevant PRC construction and environmental protection authorities. As of the date of this annual report, we have not received any administrative penalties in respect of such non-compliance. If we are not able to obtain these approvals, we could be required to pay fines, suspend production or cease operations.

As our manufacturing processes generate noise, waste water, gases and other industrial wastes, we are required to comply with all national and local regulations regarding protection of the environment. In addition, the National People’s Congress of China and the Chinese government have promulgated certain resolutions and regulations regarding climate change, which generally require enterprises to take actions to effectively manage the impact of climate change, develop renewable energy solutions and control emissions. Other than those discussed above, we believe we are in material compliance with present environmental protection requirements and regulations, and have all necessary environmental permits to conduct our business, except as disclosed herein. However, if more stringent regulations are adopted in the future, the costs of compliance with such new regulations could be substantial. We believe that we have all of the permits necessary to conduct our business as it is presently conducted. If we fail to comply with present or future environmental regulations, however, we may be required to pay substantial fines, suspend production or cease operations. We use, generate and discharge toxic, volatile and otherwise hazardous chemicals and wastes in our research and development and manufacturing activities. Any failure by us to control the use of, or to restrict adequately the discharge of, hazardous substances could subject us to potentially significant monetary damages and fines or suspensions in our business operations.

We have limited insurance coverage and may incur losses resulting from product liability claims.

As the insurance industry in China is still in an early stage of development, product liability insurance available in China offer limited coverage compared to that offered in many other countries. We have purchased product liability insurance for our solar module products, which has a term from August 2010 to August 2011. We are exposed to risks associated with product liability claims if the use of our solar power products results in injury, and we can not assure you that the product liability insurance is adequate. Since our products generate electricity, it is possible that users could be injured or killed by our products as a result of product malfunctions, defects, improper installation or other causes. We only began commercial shipment of our solar power products in August 2005, and, because of our limited operating history, we cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business. The successful assertion of product liability claims against us could result in potentially significant monetary damages and require us to make significant payments. In addition, we have purchased business interruption insurance in 2010, but we can not assure you that it is adequate.

Problems with product quality or product performance may result in a decrease in customers and revenues, incur unexpected expenses or cause us to incur warranty expenses, and may damage our market reputation and prevent us from achieving increased sales and market share.

Our products may contain defects that are not detected until after they are sold or are installed because we cannot test for all possible scenarios. We have received in the past, and may receive from time to time in the future, complaints from certain customers that portions of our solar power products have quality deficiencies. If we deliver solar power products that do not satisfy our customers’ or end users’ quality requirements, or if there is a perception that our products are of poor quality, our credibility and the market acceptance and sales of our solar power products could be harmed. We may also incur substantial expenses to compensate the customers. Historically, some of our sales contracts with overseas customers provided for a 10-year warranty for the performance of our solar cells, and in some cases, our solar cells were sold with up to a 20-year warranty. In 2010, we sold 67.2 MW of solar modules, in most cases with a five-year warranty

18

for defects in material and workmanship and a minimum power output warranty of up to 25 years following the date of purchase. As a result, we bear the risk of extensive warranty claims long after we have sold our products and recognized revenues. We have sold solar cells only since August 2005 and sold modules in large scale since November 2010. Due to the short usage history of our products, we cannot assure you that our assumptions regarding the durability and reliability of our products are reasonable. Our warranty provisions may be inadequate, and we may have to incur substantial expense to repair or replace defective products in the future. Any increase in the defect rate of our products would cause us to increase the amount of our warranty reserves and have a correspondingly negative impact on our operating results. Furthermore, widespread product failures may damage our market reputation, reduce our market share and cause our sales to decline.

If we fail to maintain an effective system of internal controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of our common shares may, therefore, be adversely impacted.

We are subject to reporting obligations under the U.S. securities laws. Beginning with our annual report on Form 20-F for the fiscal year ending December 31, 2008, we are required to prepare a management report on our internal controls over financial reporting containing our management’s assessment of the effectiveness of our internal controls over financial reporting. In addition, our independent registered public accounting firm must attest to and report on the effectiveness of our internal controls over financial reporting.

There have been historical deficiencies with our internal controls. In connection with the audit of our financial statements as of and for the year ended December 31, 2009, we and our independent registered public accounting firm identified a significant deficiency in our internal financial reporting procedure relating to the internal communications between our legal and finance department. We have undertaken remedial steps to improve our internal control over financial reporting and our disclosure controls.

In connection with the preparation of this annual report on Form 20-F, we carried out an evaluation of the effectiveness of our internal control over financial reporting. Our management excluded from our assessment the internal control over financial reporting at SST and NRE which were acquired on November 1, 2010, and whose aggregated financial statements constitute -1.9% and 25.6% of net and total assets, respectively, 4.4% of revenues, and -2.1% of net income of the consolidated financial statement amounts as of and for the year ended December 31, 2010. Based on this assessment and evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2010. However, our acquisition of the module business may strain our resources and make it difficult to maintain and update our internal control and procedures as we continue to expand. See “Item 15. Controls and Procedures.” If we fail to maintain an effective system of internal control over financial reporting and an effective system of disclosure controls in the future, we may be unable to accurately report our financial results or prevent fraud, and as a result, investor confidence and the market price of our ADSs may be adversely impacted. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs, management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act.

Our chairman has significant influence over our company, and his interests may not be aligned with the interests of our other shareholders.

Mr. Tingxiu Lu, our chairman, currently beneficially owns 14.7% of our outstanding share capital as of March 31, 2011. Most of our bank borrowings are guaranteed by CEEG, an entity controlled by Mr. Lu. CEEG guaranteed the bank borrowings of Sunergy Nanjing for up to RMB1 billion until May 2011, subject to adjustment in the event of a material change in CEEG’s credit or operational status. As both our chairman and our principal shareholder, Mr. Lu has significant influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders and holders of our ADSs, including those who purchased our ADSs in our initial public offering.

19

We have been a party in several legal proceedings, which, if determined adversely, could negatively affect our business and results of operations.

We and several of our directors and officers were named defendants in three purported class actions currently pending in the United States District Court for the Southern District of New York — Brown v. China Sunergy Co., Ltd. et al., Case No. 07-CV-07895 (DAB), Sheshtawy v. China Sunergy Co., Ltd. et al., Case No. 07-CV-08656 (DAB), and Giombetti v. China Sunergy Co., Ltd. et al., Case No. 07-CV-09689 (DAB). On September 29, 2008, the District Court appointed a lead plaintiff and consolidated the three cases. The lead plaintiff alleges that we made false and misleading statements in our registration statement and prospectus in connection with our initial public offering in May 2007 regarding, among other things, the procurement of polysilicon, and seek unspecified damages. On January 26, 2009, the defendants filed a motion to dismiss the consolidated amended complaint. Briefing on the motion was completed on May 1, 2009. Defendants’ motion remained outstanding when, on July 14, 2009, the parties reached an agreement in principle to settle the dispute in its entirety with an amount of $1.1 million. The parties are currently awaiting the hearing for final approval of the settlement, set by the Court for May 12, 2011.

We have filed a petition in a Norwegian district court seeking injunction with regard to the withdrawal of a $50 million bank guarantee, which is a security for our payment obligation under a long term supply contract entered into between REC SiTech AS, a Norwegian wafer supplier, and us in June 2008. Without obtaining our written consent as the contract requires, REC SiTech AS merged into REC Wafer Norway AS upon its dissolution on January 1, 2009. Subsequently, the bank guarantee was not renewed. REC Wafer Norway AS claimed that the non-renewal of the bank guarantee was a breach of contract which according to the supply contract is the basis for the drawdown of the bank guarantee, and it sought to draw on the bank guarantee.

The Salten District Court initially granted us the injunction prohibiting REC Wafer Norway AS from drawing on the bank guarantee but later rejected our request for an extension of the injunction upon a hearing held in January 2010. We subsequently appealed to the Court of Appeal in Norway, which denied our injunction request on April 16, 2010, and we filed a further appeal to the supreme court of Norway. The Supreme Court of Norway ruled in July 2010 overturning the Court of Appeal’s order which denied our injunction petition. Our petition was sent back to the Court of Appeal for a new ruling, which granted the injunction we petitioned and ordered that Nordea Bank Norge ASA is prohibited from making payment and REC Wafer is prohibited from receiving payment from the US$50 million bank guarantees issued by Nordea Bank Norge ASA to REC Sitech AS. The injunction will remain in force until the Court of Appeal makes a ruling on the main dispute.

The court proceeding in Norway regarding the main dispute is still ongoing. The Norwegian District Court ruled on July 5, 2010 in favor of REC Wafer. We appealed the ruling at the Court of Appeal, claiming REC Wafer is not a party to the contract originally entered between China Sunergy and the dissolved REC Sitech AS. The Court of Appeal hearing, originally scheduled for March 2011, will now be held in June 2011.

Unfavorable resolutions of these legal proceedings or any future legal proceedings could materially and adversely affect our results of operations and financial condition. See Item 8, “Financial Information — Legal Proceedings.”

Risks Related to Doing Business in China

Adverse changes in political and economic policies of the PRC government could have a material adverse effect on the overall economic growth of China, which could reduce the demand for our products and materially and adversely affect our competitive position.

All of our business operations are conducted in China and a majority of our sales are made in China. Accordingly, our business, financial condition, results of operations and prospects are affected significantly by economic, political and legal developments in China. The Chinese economy differs from the economies of most developed countries in many respects, including:

• the amount of government involvement;

• the level of development;

20

• the growth rate;

• the control of foreign exchange; and

• the allocation of resources.

While the Chinese economy has grown significantly in the past 20 years, the growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage or control economic growth and guide the allocation of resources. Some of these measures benefit the overall Chinese economy, but may also have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us. As the PRC economy is increasingly linked to the global economy, it is affected in various respects by downturns and recessions of major economies around the world, such as the recent financial services and economic crises of these economies. The various economic and policy measures enacted by the PRC government to forestall economic downturns or shore up the PRC economy could materially affect our clients’ businesses and our business.

The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. Although in recent years the PRC government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of sound corporate governance in business enterprises, a substantial portion of the productive assets in China is still owned by the PRC government. The continued control of these assets and other aspects of the national economy by the PRC government could materially and adversely affect our business. The PRC government also exercises significant control over Chinese economic growth through the allocation of resources, controlling payment of foreign currency- denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Efforts by the PRC government to slow the pace of growth of the Chinese economy could result in decreased capital expenditures by solar energy users, which in turn could reduce demand for our products.

Uncertainties with respect to the Chinese legal system could have a material adverse effect on us.

We conduct substantially all of our manufacturing operations through our PRC subsidiaries. Such PRC subsidiaries are generally subject to laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly foreign-owned enterprises. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, since these laws and regulations have not been fully developed and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involves uncertainties. We cannot predict the effect of future developments in the PRC legal system, including the promulgation of new laws, changes to existing laws or the interpretation or enforcement thereof, the preemption of local regulations by national laws, or the overturn of local government’s decisions by the superior government. These uncertainties may limit legal protections available to us. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention.

We rely on dividends paid by our subsidiary for our cash needs.

We conduct substantially all of our operations through our subsidiaries in the PRC. We rely on dividends paid by our PRC subsidiaries for our cash needs, including the funds necessary to pay dividends and other cash distributions to our shareholders, to service any debt we may incur and to pay our operating expenses. The payment of dividends by entities organized in China is subject to limitations. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. Our PRC subsidiaries are also required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves until the accumulative amount of such reserves reaches 50% of its registered capital. These reserves are not distributable as cash dividends. Our PRC subsidiaries are also required to allocate a portion of its after-tax profits, as determined by its board of directors, to its staff welfare and bonus funds, which may not be distributed to equity owners. In addition, if our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us.

21

Furthermore, the dividends we receive from our PRC subsidiaries may also be adversely affected by the Law of the People’s Republic of China on Enterprise Income Tax, or the New EIT Law, and its implementation rules, or the New EIT Law Implementation Rules, which became effective on January 1, 2008. See “— Our global income and the dividends we receive from our PRC subsidiary may be subject to PRC tax under the New EIT Law, which would have a material adverse effect on our results of operations.”

Our global income and the dividends we receive from our PRC subsidiary may be subject to PRC tax under the New EIT Law, which would have a material adverse effect on our results of operations.

Under the New EIT Law and the New EIT Law Implementation Rules, which became effective on January 1, 2008, an enterprise established outside of the PRC with “de facto management bodies” within the PRC is considered a PRC resident enterprise and will be subject to a 25% PRC enterprise income tax on its global income. The New EIT Law Implementation Rules define the term “de facto management bodies” as “establishments that carry out substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc. of an enterprise.” On April 22, 2009, the State Administration of Taxation released a circular, or the Resident Enterprise Circular, which sets out the standards and procedures for recognizing the location of the “de facto management bodies” of an enterprise registered outside of the PRC and funded by Chinese enterprises as controlling investors, or the Chinese Funded Enterprise. Under the Resident Enterprise Circular, if (i) a Chinese Funded Enterprise’s major management department and personnel who are responsible for carrying out daily operations are primarily located in the PRC; (ii) the department or the personnel who have the right to decide or approve the Chinese Funded Enterprise’s financial and human resource matters are located in the PRC; (iii) the major assets, accounting books and records, company seals, board and shareholder meeting resolutions of the Chinese Funded Enterprise are located or maintained in the PRC; and (iv) 50% or more of voting board members or senior executives habitually reside in China, such Chinese Funded Enterprise shall be considered as a PRC resident enterprise. The Resident Enterprise Circular explicitly provides that the above standards shall apply to the enterprises which are registered outside the PRC and funded by Chinese enterprises as controlling investors, therefore such standards may be cited for reference only and may not be directly adopted when considering whether our Company’s “de facto management body” is in the PRC or not. Moreover, the assessment of “resident enterprise” shall be determined by the PRC tax authorities based on the facts and circumstances of each individual case. Accordingly, it is still unclear whether we will be considered as a PRC resident enterprise under the New EIT Law as of the date of this annual report. If we are considered a PRC resident enterprise, we will be subject to a 25% PRC income tax on our global income and such 25% PRC income tax on our global income could significantly increase our tax burden and materially and adversely affect our cash flow and profitability.

Under the applicable PRC tax laws in effect before January 1, 2008, dividend payments to foreign investors made by foreign-invested enterprises such as our PRC subsidiary, Sunergy Nanjing, were exempt from PRC withholding tax. Pursuant to the New EIT Law and the New EIT Law Implementation Rules, however, dividends generated after January 1, 2008 and payable by a foreign-invested enterprise to its foreign investors will be subject to a 10% withholding tax if the foreign investors are considered as non-PRC resident enterprises without any establishment or place of business within China or if the dividends payable have no connection with the establishment or place of business of the foreign investors within China, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced withholding arrangement. The Cayman Islands, where we are incorporated, does not have such a tax treaty with China. China Sunergy (Hong Kong) Co., Ltd., or Sunergy Hong Kong, the direct holder of the 100% equity interest in Sunergy Nanjing, is incorporated in Hong Kong. According to the Mainland and Hong Kong Special Administrative Region Arrangement on Avoiding Double Taxation or Evasion of Taxation on Income agreed between China and Hong Kong in August 2006, dividends paid by a foreign-invested enterprise in China to its direct holding company in Hong Kong will be subject to withholding tax at a rate of no more than 5% (if the foreign investor owns directly at least 25% of the shares of the foreign-invested enterprise). Under the New EIT Law Implementation Rules, if we and Sunergy Hong Kong were regarded as PRC resident enterprises, the dividends payable to us from Sunergy Nanjing would be exempt from the PRC income tax. If we were regarded as a non-PRC resident enterprise and Sunergy Hong Kong were regarded as a PRC resident enterprise, then Sunergy Hong Kong would be required to withhold a 10% withholding tax on any dividends payable to us, while if Sunergy Hong Kong is regarded as a non-PRC resident enterprise, then

22

Sunergy Nanjing would be required to withhold a 5% withholding tax on any dividends payable to Sunergy Hong Kong. In either case, the amount of funds available to us to meet our cash requirements, including the payment of dividends to our shareholders and debt service on any debt we incur, could be materially reduced.

In addition, if we are regarded as a PRC resident enterprise, under the New EIT Law, any dividends to be distributed by us to our non-PRC shareholders or holders of ADSs will be subject to a withholding tax. We also cannot assure you that any gain realized by non-PRC shareholders or holders of our ADSs from the transfer of our shares or ADSs will not be subject to a withholding tax. Unless there are further rules announced by the Chinese tax authorities, we may be required under the New EIT Law to withhold PRC income tax on our dividends payable to our non-PRC shareholders or holders of ADSs, or any gain realized by our non-PRC shareholders or holders of ADSs from transfer of the shares or ADSs, and your investment in our ADSs may be materially and adversely affected.

According to a circular released by the State Administration of Taxation regarding the understanding and recognition of the identification of “beneficial owner” under tax treaties on October 27, 2009, or the Beneficial Owner Recognition Circular, a corporate resident of a contracting state will not be entitled to the lower withholding tax rate under a tax treaty if it is considered a “conduit company” which is set up merely for the purpose of avoiding or reducing tax or transferring or accumulating profits, as opposed to a beneficial owner who owns and controls an item of income, or the right or property from which that item of income is derived, and is normally engaged in substantive business activities such as manufacturing, sales and management. Therefore, if Sunergy Hong Kong were not considered to be the beneficial owner of Sunergy Nanjing as the case may be, under the terms of the Beneficial Owner Recognition Circular, we may not be able to enjoy the applicable tax treaty benefits between the PRC and Hong Kong, and any dividends paid by Sunergy Nanjing to Sunergy Hong Kong may incur a higher withholding tax rate of 10%. No similar tax treaty exists between the PRC and the Cayman Islands.

Restrictions on currency exchange may limit our ability to receive and use our revenues or financing effectively.

Certain portions of our revenues and expenses are denominated in Renminbi. If our revenues denominated in Renminbi increase or expenses denominated in Renminbi decrease in the future, we may need to convert a portion of our revenues into other currencies to meet our foreign currency obligations, including, among others, payment of dividends declared, if any, in respect of our ordinary shares or ADSs. Under China’s existing foreign exchange regulations, Sunergy Nanjing is able to pay dividends in foreign currencies, without prior approval from the State Administration of Foreign Exchange, or SAFE, by complying with certain procedural requirements. However, we cannot assure you that the PRC government will not take further measures in the future to restrict access to foreign currencies for current account transactions.

Most foreign exchange transactions by Sunergy Nanjing under capital accounts continue to be subject to significant foreign exchange controls and require the approval of, or registration with, PRC governmental authorities. In particular, if Sunergy Nanjing borrows foreign currency loans from us or other foreign lenders, these loans cannot exceed statutory limits and must be registered with the SAFE, and if we finance Sunergy Nanjing by means of additional capital contributions, these capital contributions must be approved or registered by certain government authorities including the SAFE, the Ministry of Commerce or their local counterparts. These limitations could affect the ability of Sunergy Nanjing to obtain foreign exchange through debt or equity financing, and could affect our business and financial condition.

Our business benefits from certain PRC preferential tax treatments. Expiration of, or changes to, these incentives could have a material adverse effect on our operating results.

The PRC government has provided various incentives to foreign-invested enterprises. Because Sunergy Nanjing is a foreign-invested enterprise engaged in manufacturing businesses and located in Nanjing, which is within a coastal economic zone, it was entitled to a preferential enterprise income tax rate of 24% prior to January 1, 2008. As a foreign-invested enterprise engaged in manufacturing businesses, Sunergy Nanjing is also entitled to a two-year income tax exemption and 50% reduction for the succeeding three years from the first profitable year. On March 16, 2007, the National People’s Congress of China, or the Congress, enacted the New EIT Law, under which foreign invested enterprises and domestically-owned enterprises would be

23

subject to enterprise income tax at a uniform rate of 25%. On December 6, 2007, the State Council promulgated the New EIT Law Implementation Rules. Both the New EIT Law and its Implementation Rules became effective on January 1, 2008. The New EIT Law also provides transitional measures for enterprises established prior to the promulgation of the New EIT Law and eligible for lower tax rate or preferential treatment in accordance with the then-prevailing tax laws and administrative regulations. On December 26, 2007, State Council of China promulgated the Circular on Carrying Out the Transitional Preferential Policies concerning Enterprise Income Tax, or the Circular. Under the New EIT Law, the Implementation Rules and the Circular, enterprises which were established and already enjoyed preferential enterprise income tax treatments before March 16, 2007 will continue to enjoy them (i) in the case of preferential tax rates, for a period of five years from January 1, 2008, and the enterprises which previously enjoyed the tax rate of 24% shall be subject to the tax rate of 25% in 2008, or (ii) in the case of preferential tax exemption or reduction for a specified term, until the expiration of such term or 2012, whichever is earlier. However, the Circular also prescribes that if the above transitional relief of enterprise income tax overlaps with the preferential treatments provided by the New EIT Law, an enterprise may choose the more favorable treatment, and shall not enjoy both. The treatment cannot be changed once it is chosen. In addition, on April 14, 2008, the Ministry of Finance, the Ministry of Science and Technology and the State Administration of Taxation jointly promulgated the Administration Measures for Recognition of High and New Technology Enterprises, or the Recognition Measures. Pursuant to the New EIT Law, the New EIT Law Implementation Rules and the Recognition Measures, the qualifying High and New Technology Enterprise, or HNTE, is eligible for a preferential tax rate of 15%. See “Item 4. Information On The Company — Business Overview — Regulation — Tax” for a discussion of the requirements to qualify as a HNTE. In October 2008, Sunergy Nanjing obtained the HNTE certificate with a three-year validity term from 2008 to 2010. Therefore, Sunergy Nanjing is entitled to a preferential income tax rate of 15% as long as it maintains its HNTE qualification under the New EIT Law and the Recognition Measures. Based on the Circular, the management chose to enjoy the transitional relief, i.e. 12.5% from 2008 to 2010. In December 2009, SST obtained the HNTE certificate with a three-year validity term from 2009 to 2011. Therefore, SST is entitled to a preferential income tax rate of 15% as long as it maintains its HNTE qualification.We cannot assure you that we will be able to maintain our current effective tax rate in the future. Any discontinuation of preferential tax treatment or any increase of the enterprise income tax rate applicable to Sunergy Nanjing or SST could have a material adverse effect on our financial condition and results of operations.

Our failure to obtain the prior approval of the China Securities Regulatory Commission, or the CSRC, of the listing and trading of our ADSs on the Nasdaq Global Market could have a material adverse effect on our business, operating results, reputation and trading price of our ADSs.

On August 8, 2006, six PRC regulatory agencies, including CSRC, promulgated the Regulation on Mergers and Acquisitions of Domestic Companies by Foreign Investors, which became effective on September 8, 2006.

This regulation, among other things, has certain provisions that purport to require offshore special purpose vehicles, or SPVs, formed for the purpose of acquiring PRC domestic companies and controlled by PRC individuals, to obtain the approval of the CSRC prior to listing their securities on an overseas stock exchange. The application of this PRC regulation remains unclear with no consensus currently existing among the leading PRC law firms regarding the scope and applicability of the CSRC approval requirement. On September 21, 2006, the CSRC published on its official website a notice specifying the documents and materials that are required to be submitted for obtaining CSRC approval. We believe, based on the advice of our PRC counsel, Jun He Law Offices, that although the CSRC generally has jurisdiction over overseas listing of SPVs like us, it was not necessary for us to obtain CSRC approval for our initial public offering given the fact that we had legally completed the acquisition of all the equity interest in Sunergy Nanjing before the new regulation became effective. Uncertainty as to how this regulation will be interpreted or implemented still remains. If the CSRC or another PRC regulatory agency subsequently determines that the CSRC’s approval was required for our initial public offering and offering of convertible senior notes, we may face sanctions by the CSRC or another PRC regulatory agency. If this happens, these regulatory agencies may impose fines and penalties on our operations in the PRC, limit our operating privileges in the PRC, delay or restrict the repatriation of the proceeds from our initial public offering into the PRC, restrict or prohibit payment or remittance of dividends by Sunergy Nanjing, or take other actions that could have a material adverse effect on

24

our business, financial condition, results of operations, reputation and prospects, as well as the trading price of our ADSs. Also, if later the CSRC requires that we obtain its approval, we may be unable to obtain a waiver of the CSRC approval requirements, if and when procedures are established to obtain such a waiver. Any uncertainties and/or negative publicity regarding this CSRC approval requirement could have a material adverse effect on the trading price of our ADSs.

Regulations relating to offshore investment activities by PRC residents may limit our ability to inject capital into our PRC subsidiary, limit our subsidiary’s ability to distribute profits to us, or otherwise adversely affect us.

In October 2005, SAFE issued a regulation entitled “Circular on several issues concerning foreign exchange regulation of corporate finance and roundtrip investments by PRC residents through special purpose companies incorporated overseas,” or Circular No. 75. Circular No. 75 states that if PRC residents use assets or equity interests in their PRC entities as capital contributions to establish offshore companies or inject assets or equity interests of their PRC entities into offshore companies to raise capital overseas, they must register with local SAFE branches with respect to their overseas investments in offshore companies and must also file amendments to their registrations if their offshore companies experience material events involving capital variation, such as changes in share capital, share transfers, mergers and acquisitions, spin-off transactions, long-term equity or debt investments or uses of assets in China to guarantee offshore obligations. Under Circular No. 75, failure to comply with the registration procedures set forth in such regulation may result in restrictions being imposed on the foreign exchange activities of the relevant PRC entity, including the payment of dividends and other distributions to its offshore parent, as well as restrictions on the capital inflow from the offshore entity to the PRC entity. While we believe our shareholders have complied with existing SAFE registration procedures, any future failure by any of our shareholders who is a PRC resident or controlled by a PRC resident to comply with relevant requirements under Circular No. 75 could subject our company to fines or sanctions imposed by the PRC government, including restrictions on Sunergy Nanjing’s ability to pay dividends or make distributions to us and our ability to increase our investment in or provide loans to Sunergy Nanjing.

A failure to comply with PRC regulations regarding the registration of shares and share options held by our employees who are PRC citizens may subject such employees or us to fines and legal or administrative sanctions.

Pursuant to the Implementation Rules of the Administrative Measures on Individual Foreign Exchange, or the Individual Foreign Exchange Rules, promulgated on January 5, 2007 by SAFE and the Operating Procedures on Administration of Foreign Exchange for PRC Individuals’ Participation in Employee Share Ownership Plans and Employee Share Option Plans of Overseas Listed Companies, or the Share Option Rules, issued by SAFE in March 2007, PRC citizens who are granted shares or share options by an overseas-listed company according to its employee share option or share incentive plan are required, through the PRC subsidiary of such overseas-listed company or other qualified PRC agents, to register with SAFE and complete certain other procedures related to the share option or other share incentive plan. In addition, the overseas listed company or its PRC subsidiary or other qualified PRC agent is required to appoint an asset manager or administrator and a custodian bank, and open special foreign currency accounts to handle transactions relating to the share option or other share incentive plan.

In addition, the General Administration of Taxation has issued certain circulars concerning employee share options. Pursuant to these circulars, our employees working in China who exercise their share options will be subject to PRC individual income tax. Our PRC subsidiaries have obligations to file documents related to such employee share options with relevant tax authorities and withhold individual income taxes of those employees who exercise their share options.

We and the participants of our share incentive plans who are PRC citizens are subject to these rules, and we will attempt to comply with the relevant requirements under such rules. Failure to comply with such rules may subject us and the participants of our share incentive plans who are PRC citizens to fines and legal sanctions and prevent us from further granting options and restricted share under our share incentive plans, which could adversely affect our business operations.

Increase in labor costs and the new Labor Contract Law and other labor-related regulations in the PRC may adversely affect our business and our profitability.

On June 29, 2007, the National People’s Congress of China enacted a new Labor Contract Law, which became effective on January 1, 2008. Compared to the PRC Labor Law effective as of January 1, 1995, the new Labor Contract Law imposes more restrictions and increases costs for the employers to terminate employment, including specific provisions related to fixed term employment contracts, temporary employment, probation, consultation with the labor union and employee assembly, employment without a contract, dismissal of employees, compensation upon termination and overtime work, and collective bargaining. According to the new Labor Contract Law, the employer is obliged to sign an unlimited term labor contract with an employee if the employer continues to hire the employee after two consecutive fixed term labor contracts or after the employee spends 10 consecutive years working for the employer. The employer also has to pay a compensation fee to the employee if the employer terminates an unlimited term labor contract. Unless an employee refuses to extend an expired labor contract, such compensation is also required when the labor contract expires. Further, under the Regulations on Paid Annual Leave for Employees, which became effective on January 1, 2008, employees who have served more than one year for an employer are entitled to a paid vacation ranging from 5 to 15 days, depending on their length of service. Employees who waive such vacation time at the request of employers shall be compensated for three times their normal salaries for each waived vacation day. As a result of these new protective labor measures, our labor costs are expected to increase, which may adversely affect our business and our results of operations.

We face risks related to natural disasters and health epidemics, which could have a material and adverse effect on our business and results of operations.

Our business could be adversely affected by the effects of avian flu, SARS or another epidemic or outbreak. China reported a number of cases of SARS in April 2004. Since 2005, there have been reports of occurrences of avian flu in various parts of China, including a few confirmed human cases and deaths. In April 2009, an outbreak of a new strain of influenza identified as the Influenza A (H1N1) virus occurred in Mexico resulting in a number of deaths. As the virus continued to spread worldwide including China, the World Health Organization on June 11, 2009 declared the H1N1 virus outbreak a global pandemic. The spread of H1N1 or any prolonged recurrence of avian influenza, SARS or other adverse public health developments in China could have a material adverse effect on our business operations. These could include restrictions on our ability to travel or ship our products outside of China as well as temporary closure of our manufacturing facilities. Such closures or travel or shipment restrictions would severely disrupt our business operations and adversely affect our results of operations. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of avian flu, SARS or any other epidemic. More recently, in March 2011, Japan was struck by a 9.0-magnitude earthquake and tsunami, which may affect Japan’s production of polysilicon and may result in upward pressure on pricing of silicon raw materials globally. Additionally, the production cost for solar power products is influenced by macroeconomic factors such as global economic conditions, the supply and prices of other energy products such as oil. An increase in oil prices, for example, may increase the production cost for solar power products globally. While such events in the past have not had an adverse impact on us as of the date of this annual report, future natural disasters and health hazards may severely restrict the level of economic activity in affected areas, which may in turn materially and adversely affect our business and prospects.

Risks Related to Our Shares and ADSs

The market price for our ADSs has been volatile since our ADSs began trading on NASDAQ, and may be subject to fluctuations in the future, which could result in substantial losses to investors.

The closing price of our ADSs has ranged from a high of $17.88 to a low of $1.38 since our ADSs began trading on NASDAQ on May 17, 2007. We cannot assure you that the market price of ADSs will not significantly fluctuate from its current level. The market price of our ADSs may be subject to wide fluctuations in response to factors including the following:

• announcements of technological or competitive developments;

• regulatory developments in our target markets affecting us, our customers or our competitors;

26

• announcements of studies and reports relating to the conversion efficiencies of our products or those of our competitors;

• actual or anticipated fluctuations in our quarterly operating results;

• changes in financial estimates by securities research analysts;

• changes in the economic performance or market valuations of other solar power technology companies;

• addition or departure of our executive officers and key research personnel;

• announcements regarding patent litigation or the issuance of patents to us or our competitors;

• fluctuations in the exchange rates between the U.S. dollar, the Euro and RMB;

• release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares or ADSs; and

• sales or perceived sales of additional ADSs.

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. These market fluctuations may also have a material adverse effect on the market price of our ADSs. In particular, the performance and fluctuation of market prices of other companies with business operations located mainly in China that have listed their securities in the United States may affect the volatility in the price of and trading volumes for our ADSs. The trading performances of these China-based companies’ securities at the time of or after their offerings may affect the overall sentiment toward China-based companies’ securities listed in the United States and consequently may impact the trading performance of our ADSs. Volatility in global capital markets could also have an effect on the market price of our ADSs. For example, financial markets have experienced extreme disruption in the past years, including, among other things, extreme volatility in security prices. In the event of a continuing market downturn, the market price of our ADSs may further decline.

Substantial future sales of our ADSs or ordinary shares in the public market, or the perception that these sales could occur, could cause the price of our ADSs to decline.

Additional sales of our ADSs or ordinary shares in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline. If our shareholders sell substantial amounts of our ADSs, including those issued upon the exercise of outstanding options, in the public market, the market price of our ADSs could fall. Such sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. If any existing shareholder or shareholders sell a substantial amount of ordinary shares, the prevailing market price for our ADSs could be adversely affected.

In addition, we may issue additional ordinary shares or ADSs for future acquisitions. If we pay for our future acquisitions in whole or in part with additionally issued ordinary shares or ADSs, your ownership interests in our company would be diluted and this, in turn, could have a material adverse effect on the price of our ADSs.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. Holders of our ADSs or ordinary shares.

Based on the market price of our ADSs, the value of our assets, and the composition of our income and assets, although we do not believe we were a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for our taxable year ended December 31, 2010, we cannot assure you we were not a PFIC for such year. A non-U.S. corporation will be a PFIC for any taxable year if either (1) at least 75% of its gross income for such year is passive income or (2) at least 50% of the value of its assets (based on an average of the quarterly values of the assets) during such year is attributable to assets that produce passive income or are held for the production of passive income. We must make a separate determination after the close of each taxable year as to whether we were a PFIC for that year. Because the value of our assets for purposes of the PFIC test will generally be determined by reference to the market price of our ADSs or

27

ordinary shares, fluctuations in the market price of the ADSs or ordinary shares may cause us to become a PFIC. Although we do not believe we were a PFIC for our taxable year ended December 31, 2010, because of the depressed market price of the ADSs and our retention of a significant amount of cash during such year, there is a significant risk that we could be treated as a PFIC for such year. Accordingly, we cannot assure you we were not a PFIC for such year. If we are a PFIC for any taxable year during which a U.S. Holder (as defined in Item 10, “Additional Information — Taxation — United States Federal Income Taxation”) holds an ADS or an ordinary share, certain adverse U.S. federal income tax consequences could apply to such U.S. Holder. See Item 10, “Additional Information — Taxation — United States Federal Income Taxation — Passive Foreign Investment Company.”

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings and you may not receive cash dividends if it is impractical to make them available to you.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary bank will not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act, or exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

In addition, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property and you will not receive such distribution.

Anti-takeover provisions in our charter documents may discourage a third party from acquiring us, which could limit our shareholders’ opportunities to sell their shares at a premium.

Our amended and restated memorandum and articles of association include provisions that could limit the ability of others to acquire control of us, modify our structure or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of us in a tender offer or similar transaction.

For example, our board of directors will have the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix the powers and rights of these shares, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares. Preferred shares could thus be issued quickly with terms calculated to delay or prevent a change in control or make removal of management more difficult. In addition, if our board of directors issues preferred shares, the market price of our ordinary shares may fall and the voting and other rights of the holders of our ordinary shares may be adversely affected.

Our amended and restated articles of association provide for a staggered board, which means that our directors are divided into three classes, with around one- third of our board standing for election every year. This means that, with our staggered board, at least two annual shareholders’ meetings, instead of one, are generally required in order to effect a change in a majority of our directors. Our staggered board can discourage proxy contests for the election of our directors and purchases of substantial blocks of our shares by making it more difficult for a potential acquirer to take control of our board in a relatively short period of time.

28

We are a Cayman Islands company and, because judicial precedent regarding the rights of shareholders is more limited under Cayman Islands law than that under U.S. law, you may have less protection for your rights than you would under U.S. law.

Our corporate affairs are governed by our amended and restated memorandum and articles of association, the Cayman Islands Companies Law and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as that from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. In addition, some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as shareholders of a U.S. public company.

You will have limited ability to bring an action against us or against our directors and officers, or to enforce a judgment against us or them, because we are incorporated in the Cayman Islands, because we conduct a majority of our operations in China and because the majority of our directors and officers reside outside the U.S.

We are incorporated in the Cayman Islands, and conduct substantially all of our operations in China through Sunergy Nanjing, our wholly owned subsidiary established in China. Most of our directors and officers reside outside the United States and substantially all of the assets of those persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the Cayman Islands or in China in the event that you believe that your rights have been infringed under the applicable securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of our ADSs are limited in several significant ways by the terms of the deposit agreement.

Holders of our ADSs may only exercise their voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Upon receipt of voting instructions from a holder of ADSs in the manner set forth in the deposit agreement, the depositary will endeavor to vote the underlying ordinary shares in accordance with these instructions. Under our amended and restated memorandum and articles of association and Cayman Islands law, the minimum notice period required for convening a general meeting is ten clear days. When a general meeting is convened, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw your ordinary shares to allow you to cast your vote with respect to any specific matter at the meeting. In addition, the depositary and its agents may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but we cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ordinary shares are not voted as you requested.

29

You may be subject to limitations on transfer of your ADSs.

Your ADSs, represented by American depositary receipts, are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary thinks it is necessary or advisable to do so in connection with the performance of its duty under the deposit agreement, including due to any requirement of law or any government or governmental body, or under any provision of the deposit agreement.

ITEM 4. INFORMATION ON THE COMPANY

A.History and Development of the Company

Our operating subsidiary, Sunergy Nanjing, was incorporated in August 2004 in Nanjing, China. China Sunergy Co., Ltd., or Sunergy BVI, our holding company incorporated in the British Virgin Islands, acquired all of the equity interests in Sunergy Nanjing in April 2006 through a series of transactions that we have accounted for as a legal reorganization. As part of a restructuring in anticipation of our initial public offering, we incorporated China Sunergy Co., Ltd., or Sunergy, in the Cayman Islands on August 4, 2006. Sunergy became our ultimate holding company upon its issuance of shares to the existing shareholders of Sunergy BVI on August 30, 2006 in exchange for all shares of equivalent classes that these shareholders previously held in Sunergy BVI. In December 2007, Sunergy BVI incorporated China Sunergy (Hong Kong) Co., Ltd., or Sunergy Hong Kong, in Hong Kong. During the same month, Sunergy BVI transferred all of the equity interests in Sunergy Nanjing to Sunergy Hong Kong, which became the direct holding company of Sunergy Nanjing. We conduct substantially all of our operations through Sunergy Nanjing.

In May 2007, we completed our initial public offering, in which we issued and sold 9,775,000 ADSs, representing 58,650,000 of our ordinary shares, at a public offering price of $11.00 per ADS. In July 2008, we completed our offering of $54.5 million aggregate principal amount of 4.75% convertible senior notes due June 2013 and public offering of 4,431,000 ADSs, which were loaned to an affiliate of the initial purchaser of the notes, who in turn sold the borrowed ADSs in the offering. We did not receive any proceeds from the offering of the borrowed ADSs, but has received a nominal lending fee from the ADS borrower.

As our strategy to enter into solar module business, on November 1, 2010, we completed the acquisitions of our related parties SST and NRE from CEEG, an entity controlled by Mr. Tingxiu Lu, and Sundex Holdings Limited, a company not affiliated with us. The total acquisition consideration of these two modules manufacturers are approximately RMB308.0 million ($46.0 million).

Our principal executive offices are located at No. 123 Focheng West Road, Jiangning Economic & Technical Development Zone, Nanjing, Jiangsu 211100, People’s Republic of China. Our telephone number at this address is (86-25) 5276-6688 and our fax number is (86-25) 5276-6882.

You should direct all inquiries to us at the address and telephone number of our principal executive offices set forth above. Our website iswww.chinasunergy.com. The information contained on our website does not form part of this report. Our agent for service of process in the United States is CT Corporation System, located at 111 Eighth Avenue, New York, New York 10011.

B.Business Overview

We manufacture our solar cells from silicon wafers utilizing crystalline silicon solar cell technology to convert sunlight directly into electricity through a process known as the photovoltaic effect. Before November 2010, we sold our solar cell products to Chinese and overseas module manufacturers and system integrators, who assemble our solar cells into solar modules and solar power systems for use in various markets. As part of our business strategy to achieve more vertical integration, we acquired SST and NRE, two solar module manufacturers, in November 2010 and began engaging in module manufacturing. Since then, most of our solar cells are supplied to our module business. Solar modules are arrays of interconnected solar cells encased in a weatherproof frame. Currently our end-products include solar cells and modules in different sizes and power outputs. Generally, we sell solar cells and modules under the brands of “CSUN” and “CEEG”.

We commenced business operations in August 2004. In 2005, we had only one solar cell manufacturing line. In 2006, we installed five additional solar cell manufacturing lines and expanded our annual manufacturing capacity of solar cells by 160 MW, assuming the use of 156-millimeter monocrystalline silicon wafers. Our fifth line, which achieved full scale manufacturing capacity in November 2006, commenced commercial mass production of selective emitter cells using monocrystalline silicon wafers, an improved version of the P-type solar cells that we and most other solar cell manufacturers produce, in the fourth quarter of 2007. In December 2008, we installed four new solar cell lines for the production of selective emitter cells. These four new lines are producing selective emitter cells with performance similar to those from the first line which produces selective emitter solar cells. In 2010, we installed three new solar cell lines for the production

31

of selective emitter cells. These three lines achieved full scale manufacturing capacity in December 2010 and are producing selective emitter cells with performance similar to those produced from our previous selective emitter cell lines. Hence, eight of our manufacturing lines are capable of producing high efficiency selective emitter cells. As of December 31, 2010, our 13 solar cell manufacturing lines had an aggregate annual production capacity of 404 MW, assuming the use of 156-millimeter monocrystalline silicon wafers. Upon our acquisition of SST and NRE, as of December 31, 2010, we had an aggregate annual production capacity of solar modules of 480 MW.

Since our inception, our research and development team has been led by two solar power researchers, Dr. Jianhua Zhao and Dr. Aihua Wang, who have 31 and 26 years of solar cell research experience, respectively, and established excellent credentials in the solar power industry. Our research and development efforts focus on continually enhancing our solar cell conversion efficiencies, which measure the ability of solar power products to convert sunlight into electricity, and improving our manufacturing operations of both solar cells and modules.

In 2010, our research and the production management teams have made a concerted effort to improve the performance of our standard crystalline solar cells. We have reduced the wafer-cell non-silicon cost to a new low level of $0.20 per watt in the fourth quarter of 2010 while simultaneously improved the cell efficiency. In addition, our research team continued to focus on the development of advanced process technology for manufacturing other new products, such as Quasar solar cells.

In 2008, the shipment of our solar power products amounted to 107.2 MW, including 100.4 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 2.6 MW of modules sold. In 2009, the shipment of our solar power products amounted to 194.0 MW, including 181.5 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 8.3 MW of modules sold. In 2010, the shipment of our solar power products amounted to 347.8 MW, including 277.2 MW of solar cells sold, 3.4 MW solar cells and modules processed under OEM arrangements and 67.2 MW of modules sold. We had net revenues of $350.9 million, $284.9 million and $517.2 million in 2008, 2009 and 2010, respectively. We incurred net losses of $23.3 million and $10.3 million in 2008 and 2009, respectively, and had net income of $51.7 million in 2010.

Products

We currently design, develop, manufacture and sell solar cells and solar modules.

Solar Cells

A solar cell is a device made from a silicon wafer that converts sunlight directly into electricity by a process known as the photovoltaic effect. Currently, we produce both monocrystalline and multicrystalline silicon solar cells. In addition to standard P-type solar cells and HP solar cells, we also produce since the fourth quarter of 2007 selective emitter cells, an improved version of the P-type solar cells that we and most other solar cell manufacturers produce. We sell our solar cells under the brand of “CSUN.”

The following table sets forth the types of solar cells we offered in 2010 with the specifications indicated.

Monocrystalline or Multicrystalline Solar Cell	Dimensions (mm×mm)		As a Percentage of Total Output in 2010 As Measured by MW (%)
Monocrystalline silicon solar cell		125×125		20.9
		156×156		32.0
Multicrystalline silicon solar cell		156×156		47.1

We produce a test batch of solar cells from each shipment of silicon wafers that we receive, and return the wafers if the quality is below our standards. However, normal variation in the quality of silicon wafers in shipments that meet our standards will still result in the production of a certain proportion of solar cells that do not meet our customers’ specifications.

32

Solar Modules

Solar modules are arrays of interconnected solar cells encased in a weatherproof frame. Through SST and NRE, which we acquired in 2010, we produce standard monocrystalline modules ranging from 185 W to 305 W in power output and multicrystalline modules ranging from 195 W to 295 W in power output. We build our modules to general specifications for use in a wide range of residential, commercial, industrial and other solar power generation systems. The variation in power output is based on the conversion efficiency of the cells used in our solar modules, as well as the types of cells. We assemble solar modules either from monocrystalline or multicrystalline cells. The solar cells manufactured by us accounts for approximately 86% of the supplies we procured for our module business in the last two months in 2010. Our solar modules are sealed, weatherproof and able to withstand high levels of ultraviolet radiation and moisture. We sell our module products under the brands of “CSUN” and “CEEG.”

The following table sets forth the major types of modules produced by us:

Dimensions	Weight	Maximum Power	Optimum Operating Voltage
(mm x mm)	(Kilograms)	(Watts)	(Volts)
1580 x 808	15.6	185 – 205	35.8 – 38
1490 x 990	17.2	195-230	26 – 27.3
1640 x 990	19.8	230 – 260	29.4 – 30.3
1956 x 990	23.8	275 – 305	35.2 – 36.2

Manufacturing Process

Solar Cells

The manufacturing process for our solar cells includes the following main steps:

• Chemical treatment of silicon wafers. We first fabricate a textured structure on the wafer surface through chemical treatment to reduce the reflection of sunlight. The chemical treatment process produces a surface structure, which traps sunlight into the silicon.

• Diffusion process. Diffusion is a thermal process through which we selectively incorporate impurities into the silicon wafer and form an electrical field within the surface region of the wafer.

• Back junction removal. We achieve electrical isolation between the front and back surfaces of the silicon wafer through a process known as backside etching technology.

• Anti-reflection coating and surface passivation. We apply an anti-reflection coating to the front surface of the solar cell, which helps to significantly reduce the light reflection at the cell surface. Such coating also passivates the cell surface to reduce the carrier loss at the surface and hence increases the cell current density. Our surface coating technology ensures the appropriate thickness and refractive index of the coating to achieve high conversion efficiencies.

• Screen printing and firing. We screen print negative and positive metal contacts, or electrodes, on the solar cell. Silicon and metal electrodes are then connected through an electrode firing process in a furnace at a high temperature.

• Testing, sorting and packaging. The cells, once manufactured, are tested on the cell tester, and sorted according to their electrical performance and according to their visual appearance. They are then packed for shipment.

Solar Modules

Solar modules are formed by interconnecting multiple solar cells into desired electrical configurations through welding. The interconnected cells are laid out and laminated in a vacuum. Through these processes, the solar modules are weather-sealed, and thus are able to withstand high levels of ultraviolet radiation, moisture, wind and sand. Assembled solar modules are packaged in a protective aluminum frame prior to testing.

Manufacturing Capacity and Manufacturing Facilities

Solar Cells

Since our inception in August 2004, we have significantly expanded our manufacturing capacity to capture a larger portion of the market opportunity for our solar cells. In June 2005, we completed construction on a green-field site and started trial production of our first manufacturing line with a production capacity of 32 MW per year, assuming the use of 156-millimeter monocrystalline silicon wafers. We sold 4.4 MW of solar cells in 2005.

We completed our second to sixth solar cell manufacturing lines and started generating revenues from these lines in 2006.

Our fifth line, which achieved full scale manufacturing capacity in November 2006, commenced commercial mass production of selective emitter cells using monocrystalline silicon wafers in the fourth quarter of 2007. In 2008, we installed four new solar cell lines for the production of selective emitter cells. These four new lines are producing selective emitter cells with performance similar to those from the first line which produces selective emitter solar cells. In 2008, we also converted four of our standard P-type solar cell manufacturing lines into HP solar cell manufacturing lines, three of which are capable of producing HP solar cells using multicrystalline silicon wafers as raw materials. In August 2009, we converted another standard P-type solar cell manufacturing line into HP solar cell manufacturing lines. In 2010, we installed three new solar cell lines. These three lines achieved full scale manufacturing capacity in December 2010 and are producing solar cells with performance similar to those from our previous solar cell lines.

As of December 31, 2010, we had 13 solar cell manufacturing lines. Five of them are capable of producing HP solar cells and eight are capable of producing both selective emitter solar cells and HP solar cells, with an aggregate annual production capacity of 404 MW, assuming the use of 156-millimeter monocrystalline silicon wafers. Our actual output of solar cells depends on the size of the silicon wafers that we use; historically we have used a mix of monocrystalline and multicrystalline silicon wafers, each in sizes of 125 millimeters or 156 millimeters.

Solar Modules

As of December 31, 2010, through the acquisition of SST and NRE, we had an aggregate annual module production capacity of 480 MW. Our actual output of solar modules depends on the type of the solar cells that we use; historically we have used a mix of monocrystalline solar cells and multicrystalline solar cells in the sizes of 125×125 mm and 156 × 156 mm. With our expansion into downstream solar module business, we expect to sell substantially all of our solar cell products to SST and NRE for our module manufacturing. In addition, as our current solar cell production capacity does not match our solar module production capacity, we will also purchase solar cells from outside solar cell suppliers in 2011.

Raw Materials

Silicon wafers are the most important raw materials for producing solar cells, with monocrystalline and multicrystalline silicon wafers as the most commonly used materials. We can produce solar cells with either of these types of silicon wafers, and this dual capability provides us with flexibility in raw material procurement.

We seek to procure silicon wafers from various suppliers, most of which are manufacturers located in China. In addition, we also procure polysilicon from various suppliers, and outsource the production of silicon wafers from these polysilicon raw materials under toll manufacturing arrangements with third parties. Sometimes, we sell polysilicon raw materials to wafer manufacturers and purchase silicon wafers from them under buy-and-sell arrangements. In order to meet a portion of our raw material requirements, we also enter into buy-and-sell arrangements with some of our customers, under which we secure silicon wafers from some of our customers, and sell solar cells to them in return.

In 2010, our principal suppliers of silicon wafers and other silicon-based raw materials included CEEG (Nanjing) Semiconductor Co., Ltd., COMTEC Solar Systems Group Limited, TBEA Sunoasis Co., Ltd, Jiangxi LDK Solar Hi-Tech Co. Ltd., and Heraeus Materials Technology Shanghai Ltd.Our top five suppliers supplied approximately 34.1% of silicon wafers and other supplies that we procured in 2010. Due to the industry-wide shortage of silicon raw materials experienced during the past few years, we purchased silicon raw materials using short-term and long-term contracts from a limited number of international and domestic suppliers. Some agreements provide for firm purchase commitments and fixed pricing or pricing adjustable within a relatively small range. From the fourth quarter of 2008 to mid-2009, the price of silicon raw materials decreased rapidly due to the excess supply of silicon raw materials resulting from a slowed global solar power market growth. In light of such excess supply, we have sought to re-negotiate with our long-term supply partner in regard to certain long term supply contract signed in 2008. In 2009 and 2010, almost all of our purchases of silicon raw materials were made under short-term contracts. In February 2011, in order to secure long-term supply of silicon wafer while maintaining ability to keep the price at the market level, we entered into a 6-year contract with GCL-Poly Energy Holdings Limited, or GCL-Poly. The agreement contains a clause for a price adjustment mechanism based on wafer market price. Given the current wafer price environment, we also seek to exert greater control over incoming wafer quality while establishing stable and long-term relationships with high quality suppliers.

Our manufacturing process also involves metallic paste, chemicals and other materials. We secure these raw materials from multiple vendors who have demonstrated good quality control and reliability.

Quality Assurance and Customer Support and Service

Our quality control consists of three components: incoming inspection through which we ensure the quality of the raw materials that we source from third parties, in-process quality control of our manufacturing processes, and output quality control of finished products through inspection and testing. We have received the ISO 9001:2008 certification for our quality assurance programs, which we believe demonstrates our technological capabilities and instills customer confidence. We strictly adhere to the standards enacted by international authoritative institutions in our operation. In addition, we also ensure that the performance of our products is adherent to specified standards when testing the conversion efficiency of our products.

A team within our sales group works closely with our quality assurance group to provide customer support and service. We emphasize gathering customer feedback for our products and timely addressing customer concerns. Our customer support and service team also provides our customers with training and consultation with respect to the application of our products.

Customers and Markets

Before our acquisition of SST and NRE on November 1, 2010, we sold our solar cells primarily to module manufacturers, who assemble our cells into solar modules and solar power systems for use in various markets, particularly the European market. Historically, we also outsourced to third parties the manufacturing of solar modules from our solar cells or purchase solar modules from third parties for sale of such solar modules to our customers. In the first ten months of 2010, solar module sales accounted for 4.8% of our revenues. After we acquired the two module manufacturers, the majority of our solar cells were used for our module production. The solar cells manufactured by us account for approximately 86% of the supplies we procured for our module business in the last two months in 2010. Sales generated from solar cells and solar modules accounted for 9.0% and 89.7%, respectively, of our revenues in the last two months of 2010. We expect to lower our cost and achieve higher profit by supplying most of our solar cells to our module manufacturing in future.

In 2010, our major customers of solar cell business included NRE, SST, ILB HELIOS SPAIN, S.A., Solaire Direct Technologies, and asola Advanced and Automotive Solar Systems GmbH. In 2010, our major customers of solar module business included Ecoware S.p.A. (Gruppo Kerself), P.M.service s.r.l, TENERGIE, CEEG Nanjing International Trade Co., Ltd. and CEEG (Nanjing) Solar Research Institute. In 2010, our top five customers contributed over 57.7% of our net revenues in 2010, including SST and NRE, both of which were completely acquired by us on November 1, 2010, which contributed approximately 23.6% and 23.2%, respectively, of our net revenues in 2010 prior to the acquisition.

In 2010, we made a majority of our sales to customers located in China. We also sell our solar power products to customers located in Italy, Germany, Spain and other countries. The following table sets forth by region our net revenues derived from sales of our products for the periods indicated:

	Year Ended December 31,

In order to continue growing our sales and to reduce our reliance on any particular market segment, we intend to broaden our geographic presence and customer base. While we expect China to continue to be one of our key markets for the foreseeable future, we plan to further expand into several overseas solar power markets, including European countries and those countries and regions with growing demand or market potential for solar power products, such as Italy, Germany, France, United States, India, Australia, Japan and other countries and regions as we expand into downstream solar power business.

37

We sell our products primarily under sales contracts, purchase orders and buy-and-sell arrangements, as follows:

• Sales contracts and purchase orders. Historically, we entered into sales contracts of various terms with our customers and were obligated to deliver solar power products according to a pre-agreed price and schedule during the term of the contract. Given the volatility in average selling prices of silicon raw materials and solar power products in recent periods, a substantial portion of our contracts now provide for re-negotiation of price terms based on regular pricing reviews every three or six months or provide for adjustment of pricing terms when the change in exchange rate reaches certain benchmarks. We typically require our customers to pay a certain percentage of the purchase price as advance payment within a short period after signing the sales contracts. The percentage of advance payments varies depending on the credit status of our customers, our relationship with the customers, market demand and the terms of a particular contract. We may grant our large customers credit terms, usually within 30-60 days, according to our current credit policy. With respect to the other customers, we typically request full payment before or upon shipment. We also sell our solar power products via purchase orders placed by our customers. As we expand into downstream solar power business, we continue to use the combination of sales contracts and purchase orders to directly sell solar modules to end customers.

• Buy-and-sell arrangements. Historically, we obtained silicon wafer supplies from our customers, and were obligated to sell solar cells to them in return under buy-and-sell arrangements. The payment we make for the wafers and the payment our customers make for the solar cells are either settled separately or sometimes offset against each other.

Historically, we also processed silicon wafers provided by our customers into solar cells under OEM arrangements, and we charged processing fees from these customers.

From 2008, particularly in the fourth quarter of 2008 and the first quarter of 2009, partly due to the impact of global financial market disruption and economic slowdown, some of our customers cancelled or delayed orders for our products. Purchases of solar power products tend to decrease during the winter months because of adverse weather conditions in certain regions, which complicate the installation of solar power systems. Historically, our results of operations have been affected by such seasonality of industry-wide demand for solar power products.

Sales and Marketing

We currently market and sell our solar power products worldwide mainly through our direct sales force. We also have sales force in Germany to expand our overseas market. Our marketing programs include industrial conferences, trade fairs, advertising and public relation events, and seminars to solicit customers. Our sales and marketing groups work closely with our research and development and manufacturing groups to coordinate our product development activities, product launches and ongoing demand and supply planning. We are building a global sales network and have established three regional sale offices, one in Shanghai, China, one in Munich, Germany, and a third in California, U.S.A. We may establish more subsidiaries or regional offices in other European countries, and Japan in the future to further expand our sales network. In addition, we also sell some of our solar power products through distributors. In 2010, 32.3% of our revenues generated from module sales was derived from sales made through distributors. We expect this percentage to increase in the future as we expand into downstream solar power business.

Historically, the identity of our customers has changed substantially from year to year. We aim to further develop long-term relationships with key customers who are market leaders or strong niche players in their respective industrial or geographic segments. We believe that these customers will provide consistent revenue streams to minimize business volatility, and we target to achieve a substantial portion of our total net revenues from sales to strategic customers. To further diversify our customer base, which historically consisted primarily of module manufacturers and system integrators purchasing solar cells as we historically focused on solar cell business, we will seek to increase our sales to system integrators, solar power project developers and solar product distributors in connection with our expansion into downstream solar power business. We also rely on distributors for 32.3% of our revenues generated from module sales in 2010 and we expect that we

38

will continue to rely on distributors in our module sales in the future as such distributors have better sources and relations with end users of our solar modules.

Intellectual Property

As of the date of this annual report, Sunergy Nanjing have 12 patents in China, one on process technology for the manufacture of N-type solar cells, four on process technology for the improvement of cell performance, two on utility models for N-type solar cells, two on utility model for improvement on performance of solar cells, two on utility model for processing instruments of cells and the remaining one on utility model for cell-made tile. In addition, Sunergy Nanjing have 11 patent applications pending in China, three on the manufacturing of solar cells, three on process technology for solar cells, one on improving solar cell performance, one on rectification of bowed solar cells, one on measurement instrument for ancillary manufacturing instrument and the remaining one on packaging of solar cells. Our newly acquired PRC subsidiary SST has 11 patents on utility model in China, including one on N-type solar cell structure, two on manufacturing equipments of solar modules, three on structure of solar modules, two on manufacturing equipments of solar cells, one on manufacturing equipments of solar constructions, one on solar street lights and one on solar tiles. SST also has 13 patent application pending in China, one on solar cell frame, two on model of solar modules, one on manufacturing equipment of solar modules, one on utility model of solar tiles, one on solar cell safe sucker, one on accessory of solar street light, four on utility model of solar cell moulds, one on manufacturing equipment of recycling of condensed water and one on modular unit of solar module. We intend to continue to assess appropriate opportunities for patent protection of those aspects of our technology that we believe provide significant competitive advantage to us.

We also rely on a combination of trade secrets and employee contractual protections to establish and protect our proprietary rights. We believe that many elements of our solar power products and manufacturing processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including technical processes, equipment designs, algorithms and procedures. We have taken security measures to protect these elements. All of our research and development personnel have entered into confidentiality and proprietary information agreements with us. These agreements address intellectual property protection issues and require our employees to assign to us all of their inventions, designs and technologies that they develop primarily utilizing our resources or when performing their duties during their employment.

We are the registered owner of the trademarks “NPV” and “CSUN” and two logos in China. Further, CEEG and Sunergy Nanjing entered into two trademark license agreements effective as of February 9, 2006 and June 7, 2006, respectively, pursuant to which CEEG granted to Sunergy Nanjing the rights to use the trademarks of “CEEG” and its Chinese characters in Sunergy Nanjing’s ordinary business for ten years. In addition, each of SST and NRE entered into trademark license agreements with CEEG on September 1, 2007, pursuant to which these two companies were granted the rights to use the trademarks of “CEEG” and another logo with a ten-year period.

Competition

The market for solar power products is highly competitive and continually evolving. We expect to face increased competition, which may result in price reductions, reduced margins or loss of market share. We believe that the key competitive factors in the market for solar power products include:

• manufacturing efficiency;

• conversion efficiency and performance;

• price;

• strength of supplier relationships; and

• reputation.

We used to compete with specialized solar power manufacturers such as JA Solar Holdings Co., Ltd., Motech Industries Inc., Q-Cells AG and Solarfun Power Holdings Co., Ltd. when we focused on solar cell business. As we expand into downstream solar module business at the end of 2010, our current competitors include specialized solar power manufacturers such as Sunpower Corp, Suntech Power Holdings Co., Ltd.,

39

Sharp Corporation, Trina Solar Ltd,.Yingli Green Energy Holding Co., Ltd., Canadian Solar Inc., Hanwha SolarOne Ltd., and Jinko Solar Holding Co., Ltd. Some of our competitors have also become vertically integrated, from polysilicon, wafer and module manufacturing to solar power system integration, such as Yingli Green Energy Holding Co., Ltd.

Many of our competitors may be developing or currently producing products based on alternative solar power technologies, such as Panda cell of Yingli Green Energy Holding Co., Ltd. and Maple cell of JA Solar Holdings Co., Ltd., which may ultimately have costs similar to, or lower than, our projected costs. We expect that we will also need to compete with new entrants to the solar power market. In addition, the entire solar power industry also faces competition from conventional and non-solar renewable energy technologies.

Many of our existing and potential competitors have substantially greater financial, technical, manufacturing and other resources than we do. Our competitors’ greater size in some cases provides them with a competitive advantage with respect to manufacturing costs due to their economies of scale and their ability to purchase raw materials at lower prices. Many of our competitors also have more established distribution networks and larger customer bases. As a result, they may be able to devote greater resources to the research, development, promotion and sale of their products or respond more quickly to evolving industry standards and changes in market conditions than we can.

REGULATION

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China or our shareholders’ rights to receive dividends and other distributions from us.

Renewable Energy Law and Other Government Directives

In February 2005, China enacted its Renewable Energy Law, which became effective on January 1, 2006. The Renewable Energy Law sets forth policies to encourage the development and use of solar energy and other non-fossil energy. The renewable energy law sets out the national policy to encourage and support the use of solar and other renewable energy and the use of on-grid generation. It also authorizes the relevant pricing authorities to set favorable prices for the purchase of electricity generated by solar and other renewable power generation systems.

The law also sets out the national policy to encourage the installation and use of solar energy water-heating systems, solar energy heating and cooling systems, solar photovoltaic systems and other solar energy utilization systems. It also provides the general principles regarding financial incentives for the development of renewable energy projects. The projects, as listed in the renewable energy industry development guidance catalogue, may obtain preferential loans from financial institutions and can enjoy tax preferences. The State Council is authorized to stipulate the specific tax preferential treatments. However, so far, no rule has been issued by the State Council pertaining to this matter. In January 2006, China’s National Development and Reform Commission promulgated two implementation directives of the Renewable Energy Law. These directives set out specific measures in setting prices for electricity generated by solar and other renewal power generation systems and in sharing additional expenses occurred. The directives further allocate the administrative and supervisory authorities among different government agencies at the national and provincial levels and stipulate responsibilities of electricity grid companies and power generation companies with respect to the implementation of the Renewable Energy Law. In July 2007, China’s National Development and Reform Commission further promulgated an implementation directive of the Renewable Energy Law. The directive stipulates the responsibility of electricity grid companies to buy all electricity generated by renewable energy power generation systems.

PRC Ministry of Construction also issued directives in September 2006 and February 2007, which seek to expand the use of solar energy in residential and commercial buildings and encourages the increased application of solar energy in different townships.

In addition, the State Council promulgated a directive in July 2005 which sets out specific measures to conserve energy resources.

40

On March 23, 2009, PRC Ministry of Finance promulgated the Interim Measures for Administration of Government Subsidy Funds for Application of Solar Photovoltaic Technology in Building Construction, or the Interim Measures, to support the demonstration and the promotion of solar photovoltaic application in China. Local governments are encouraged to issue and implement supporting policies for the development of solar photovoltaic technology. Under these Interim Measures, the Ministry of Finance provides subsidies for projects with individual solar installations that are greater that 50 kilowatt-peak in size and have more than 16% conversion efficiency for monocrystalline solar power products, more than 14% conversion efficiency for multicrystalline solar power products and more than 6% conversion efficiency for amorphous silicon solar power products, and gives priority support to solar power technology integrated into building construction, grid-connected solar power building applications and some public solar power building applications such as schools, hospitals and offices. For 2009, the standard subsidy is set at RMB20 per watt in principle and the detailed standard is to be determined by factors including, but not limited to, the level of integration of buildings with solar power and the technology of solar power products. The Interim Measures do not apply to projects completed before March 23, 2009, the promulgation date of the Interim Measures.

On April 16, 2009, the General Offices of the PRC Ministry of Finance and the PRC Ministry of Housing and Urban-Rural Development jointly issued the Guidelines for Declaration of Demonstration Project of Solar Photovoltaic Building Applications. These guidelines set the subsidies given out in 2009 to qualified solar projects at no more than RMB20 per watt for projects involving the integration of solar power components into buildings’ structural elements and at no more than RMB15 per watt for projects involving the installation of solar power components onto building rooftops and wall surfaces.

On July 16, 2009, PRC Ministry of Finance, Ministry of Science and Technology and National Energy Administration jointly issued the Notice on Implementation of Demonstration Project of Golden Sun to support the promotion of photovoltaic generation in China. Under this notice, the photovoltaic projects which meet certain requirements will be provided with subsidies. On November 9, 2009, Ministry of Finance, Ministry of Science and Technology and National Energy Administration further jointly issued the Notice on Successful Implementation of Demonstration Project of Golden Sun to emphasize the requirements for subsidizing the photovoltaic projects. On September 21, 2010, PRC Ministry of Finance, Ministry of Science, Ministry of Housing and Urban-Rural Development and Technology and National Energy Administration jointly issued the Notice on Enhancing the Administration of Construction of the Demonstration Project of Golden Sun and the Demonstration Project of Solar Photovoltaic Building Applications to further regulate the standards for the projects and subsidies. On November 19, 2010, PRC Ministry of Finance, Ministry of Science and National Energy Administration jointly issued the Notice on Enhancing the Demonstration Project of Golden Sun to further regulate the application for subsidies.

Environmental Regulations

We are subject to a variety of governmental regulations related to environmental protection. The major environmental regulations applicable to us include the Environmental Protection Law of the PRC, the Law of PRC on the Prevention and Control of Water Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Water Pollution, the Law of PRC on the Prevention and Control of Air Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Air Pollution, the Law of PRC on the Prevention and Control of Solid Waste Pollution, and the Law of PRC on the Prevention and Control of Noise Pollution.

We are in compliance with present environmental protection requirements in all material aspects and have all necessary environmental permits to conduct our business, except as disclosed herein, see “Item 3 — Key Information — D. Risk Factors — Risks Related to Our Company and Our Industry — Noncompliance with present or future construction and environmental regulations may result in potentially significant monetary damages and fines”. Our operations are subject to regulation and periodic monitoring by local environmental protection authorities.

41

Restriction on Foreign Ownership

The principal regulation governing foreign ownership of solar power businesses in the PRC is the Foreign Investment Industrial Guidance Catalogue, effective as of December 1, 2007, or the Catalogue. The Catalogue classifies the various industries into four categories: encouraged, permitted, restricted and prohibited. As confirmed by the government authorities, Sunergy Nanjing, our operating subsidiary, is engaged in an encouraged industry. Sunergy Nanjing is permitted under the PRC laws to be wholly owned by a foreign company. Sunergy Nanjing is, accordingly, also entitled to certain preferential treatments granted by the PRC government authorities, such as exemption from tariffs on equipment imported for its own use.

Tax

PRC enterprise income tax is calculated primarily on the basis of taxable income determined under PRC enterprise income tax laws and regulations. In accordance with the Income Tax Law of China for Enterprises with Foreign Investment and Foreign Enterprises promulgated as of April 9, 1991 and effective on July 1, 1991, or the Income Tax Law, and its implementing rules, or the Income Tax Law Implementation Rules, foreign-invested enterprises incorporated in the PRC were generally subject to an enterprise income tax rate of 33% (30% of state income tax plus 3% of local income tax). The Income Tax Law and the Income Tax Law Implementation Rules provided certain preferential tax treatments to foreign-invested enterprises established in certain areas in the PRC.

Sunergy Nanjing, a foreign-invested enterprise engaged in a manufacturing business and established in Nanjing, which is within a coastal economic zone, was entitled to a preferential enterprise income tax rate of 24%. As a wholly foreign owned enterprise engaged in a manufacturing business, Sunergy Nanjing was also entitled to a two-year exemption of the enterprise income tax from its first profitable year, which was 2006, and to a 50% reduction of its applicable income tax rate for the succeeding three years,. To enjoy the above preferential treatment, the operation duration of Sunergy Nanjing shall be no less than 10 years.

On March 16, 2007, the National People’s Congress of China promulgated the New EIT Law. On December 6, 2007, the State Council promulgated the New EIT Law Implementation Rules. Both the New EIT Law and the New EIT Law Implementation Rules became effective on January 1, 2008. Under the New EIT Law and the New EIT Law Implementation Rules, domestically-owned enterprises and foreign-invested enterprises are all subject to a uniform tax rate of 25%. The New EIT Law also provides transitional measures for enterprises established prior to the promulgation of the New EIT Law and eligible for lower tax rate or preferential treatment in accordance with the then-prevailing tax laws and administrative regulations. On December 26, 2007, State Council of China promulgated the Circular. Under the New EIT Law, the New EIT Law Implementation Rules and the Circular, enterprises which were established and already enjoyed preferential enterprise income tax treatments before March 16, 2007 will continue to enjoy them (i) in the case of preferential tax rates, for a period of five years from January 1, 2008, and the enterprises which previously enjoyed the tax rate of 24% shall be subject to the tax rate of 25% in 2008, and (ii) in the case of preferential tax exemption or reduction for a specified term, until the expiration of such term or 2012, whichever is earlier. However, The Circular also prescribes that if the above transitional relief of enterprise income tax overlaps with the preferential treatments provided by the New EIT Law, an enterprise may choose the more favorable treatment, but cannot enjoy both. The treatment cannot be changed once it is chosen.

On April 14, 2008, the Ministry of Finance, the Ministry of Science and Technology and the State Administration of Taxation jointly promulgated the Recognition Measures. Pursuant to the New EIT Law, the New EIT Law Implementation Rules and the Recognition Measures, HNTE is eligible for a preferential tax rate of 15%.

42

Pursuant to Article 10 of theAdministrative Measures for Certification of New and High Technology Enterprises promulgated as of April 14, 2008 and effective on January 1, 2008, the certification of HNTE shall satisfy all the following conditions:

• The enterprises registered in China shall have independent intellectual property rights of key technologies of their main products (services) gained through independent research and development, transfer, donation or acquisition in the recent three years, or through exclusive permission for over five years;

• Of the expenses earmarked for research and development, the total expenses for research and development accrued in the territory of China shall account for no less than 60% of the total expenses for research and development. Where the period of registration and establishment of the enterprise is less than 3 years, the said ratio shall be accumulated according to its actual operation period;

• The income from high and new technology products shall account for more than 60% of the total income of the enterprise in the year;

• The enterprise’s capacity of research and development and organization, capacity of transformation of scientific achievements, amount of independent intellectual property rights, index of growth of sales and total assets shall be in conformity with requirements of Directions on Certification and Management of New and High Technology Enterprises.

On October 21, 2008, Sunergy Nanjing obtained a HNTE certificate with a three-year validity term from 2008 to 2010. Therefore, Sunergy Nanjing is eligible for a 15% preferential tax rate during the above period. Based on the Circular, our management chooses to enjoy the transitional relief, i.e. 12.5% from 2008 to 2010, for Sunergy Nanjing.

SST was acquired in November 2010. It obtained the HNTE certificate in 2009, with a valid period between 2009 and 2011, and thus is eligible for a 15% preferential tax rate during this period.

NRE was acquired in November 2010 and its applicable enterprise income tax rate is 25%.

Sunergy Shanghai was established in November 2007 and its applicable PRC enterprise income tax rate is 25%.

Pursuant to the Provisional Regulation of China on Value Added Tax and its provisional rules, all entities and individuals that are engaged in the sale of goods, the provision of processing, repairs and replacement services and the importation of goods into China are generally required to pay value added tax, or VAT, at a rate of 17.0% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayer. Further, when exporting goods, the exporter is entitled to a portion or all of the refund of VAT that it has already paid or borne. Accordingly, our PRC subsidiaries are subject to the 17.0% VAT with respect to their sales of solar power products in China, while export sales of our solar power products are exempt from such VAT.

Foreign Currency Exchange

The principal regulations governing foreign currency exchange in China are the Foreign Exchange Administration Regulations (1996), as amended in 1997 and 2008 respectively. Under these regulations, the Renminbi is freely convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions. However, for capital account items, such as direct investment, loan, repatriation of investment and investment in securities outside China, the conversion of foreign currencies into Renminbi is subject to the prior approval of SAFE, but the conversion of Renminbi into foreign currencies for the international payment and remittance under capital accounts is generally exempt from SAFE’s prior approval unless otherwise required by Chinese laws and regulations.

Pursuant to the Administration Rules of the Settlement, Sale and Payment of Foreign Exchange (1996), enterprises may only buy, sell or remit foreign currencies at banks that are authorized to conduct foreign exchange business after the enterprise provides valid commercial documents and relevant supporting documents and, in the case of certain capital account transactions, after obtaining approval from SAFE or its competent local branches. Capital investments by enterprises outside of China are also subject to limitations, which include approvals by the Ministry of Commerce, SAFE and the National Development and Reform Commission, or their respective competent local branches.

Pursuant to the Notice of the General Affairs Department of the State Administration of Foreign Exchange on the Relevant Operating Issues concerning the Improvement of the Administration of Payment and Settlement of Foreign Currency Capital of Foreign-funded Enterprises (2008), the foreign currency capital of foreign invested enterprises, after being converted to Renminbi, can only be used for doing business within the business scope approved by relevant governmental authorities, and shall not be used for domestic equity investment unless otherwise provided for.

The business operations of Sunergy Nanjing, which are subject to the foreign currency exchange regulations, have all been in compliance with these regulations in all material aspects.

Dividend Distribution

The principal regulations governing distribution of dividends of wholly foreign-owned enterprises include the Wholly Foreign- owned Enterprise Law (1986), as amended by the Decision on Amending the Law of the PRC on Wholly Foreign-owned Enterprise (2000), and the Implementing Rules of the Wholly Foreign-owned Enterprise Law (1990), as amended by the Decision of the State Council on Amending the Implementing Rules of the Law of the PRC on Wholly Foreign-owned Enterprises (2001).

Under these regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations. In addition, wholly foreign owned enterprises in China are required to set aside at least 10% of their respective after-tax profits based on PRC accounting standards each year, if any, to fund its general reserves fund, until the accumulative amount of such reserves reaches 50% of its registered capital. These reserves are not distributable as cash dividends. A wholly foreign owned enterprise is also required to allocate a portion of its after-tax profits, as determined by its board of directors, to its staff welfare and bonus funds.

Share Incentive Plan

On March 28, 2007, SAFE promulgated the Operating Procedures on Administration of Foreign Exchange for PRC Individuals’ Participation in Employee Share Ownership Plans and Employee Share Option Plans of Overseas Listed Companies, or the Share Option Rules. Under the Share Option Rules, PRC citizens who are granted shares or share options by an overseas-listed company according to its employee share option or share incentive plan are required, through the PRC subsidiary of such overseas-listed company or other qualified PRC agents, to register with SAFE and complete certain other procedures related to the share option or other share incentive plan. In addition, the overseas-listed company or its PRC subsidiary or any other qualified PRC agent is required to appoint an asset manager or administrator and a custodian bank, and open special foreign currency accounts to handle transactions relating to the share option or other share incentive plan. The General Administration of Taxation has also issued certain circulars concerning employee share options. Pursuant to these circulars, our employees working in China who exercise their share options will be subject to PRC individual income tax. Our PRC subsidiaries have obligations to file documents related to such

44

employee share options with relevant tax authorities and withhold individual income taxes of those employees who exercise their share options. Failure to comply with such rules may subject such overseas-listed company and the participants of share incentive plan who are PRC citizens to fines and legal sanctions and prevent the overseas-listed company from further granting options under its share incentive plan to its employees.

Intellectual Property Rights

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion of our financial condition and results of operations is based upon and should be read in conjunction with our consolidated financial statements and their related notes included in this annual report on Form 20-F. This report contains forward-looking statements. See “Introduction — Forward-Looking. Information.” In evaluating our business, you should carefully consider the information provided under the caption “Risk Factors” in this annual report on Form 20-F. We caution you that our businesses and financial performance are subject to substantial risks and uncertainties.

A.Operating Results

Overview

Before we acquired SST and NRE on November 1, 2010, we sold our solar cell products mostly to module manufacturers and, to a lesser extent, to system integrators, who assembled our cells into solar modules and solar power systems for use in various markets. Our management’s operational expertise and execution capability, coupled with our strong research and development capabilities, have allowed us to rapidly install our solar cell manufacturing lines and expand our manufacturing capacity. As of December 31, 2010, we had 13 solar cell manufacturing lines with an aggregate production capacity of 404 MW per year, assuming the use of 156-millimeter monocrystalline silicon wafers. Our research and development efforts focus on continually enhancing our solar cell conversion efficiencies, which measure the ability of solar power products to convert sunlight into electricity, and improving our manufacturing operations. We commenced business operations in August 2004. In 2005, we had only one solar cell manufacturing line. In 2006, we installed five additional solar cell manufacturing lines and expanded our annual manufacturing capacity by 160 MW, assuming the use of 156-millimeter monocrystalline silicon wafers. Our fifth line, which achieved full scale manufacturing capacity in November 2006, commenced commercial mass production of selective emitter cells using monocrystalline silicon wafers in the fourth quarter of 2007. In December 2008, we installed four new solar cell lines for the production of selective emitter cells. These four new lines are producing selective emitter cells with performance similar to those from the first line which produces selective emitter solar cells. In 2010, we installed three new solar cell lines for the production of selective emitter cells. These three lines achieved full scale manufacturing capacity in December 2010 and are producing selective emitter cells with performance similar to those from our previous selective emitter cell lines. Hence, eight of our manufacturing lines are capable of producing high efficiency selective emitter cells.

In 2010, our research and the production management teams have made a concerted effort to improve the performance of our standard crystalline solar cells. We have reduced the wafer-cell non-silicon cost to a new low level of $0.20 per watt in the fourth quarter of 2010 while simultaneously improved the cell efficiency. In addition, our research team continued to focus on the development of advanced process technology for manufacturing other new products, such as Quasar solar cells.

As part of our business strategy to achieve more vertical integration, we began engaging in module manufacturing upon acquisition of SST and NRE, two solar module manufacturers, in November 2010. As of December 31, 2010, we had an aggregate module annual production capacity of 480 MW.

In 2008, the shipment of our solar power products amounted to 107.2 MW, including 100.4 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 2.6 MW of modules sold. In 2009, the shipment of our solar power products amounted to 194.0 MW, including 181.5 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 8.3 MW of modules sold. In 2010, the shipment of our solar power products amounted to 347.8 MW, including 277.2 MW of solar cells sold, 3.4 MW solar cells and modules processed under OEM arrangements and 67.2 MW of modules sold. We had net revenues of $350.9 million, $284.9 million and $517.2 million in 2008, 2009 and 2010, respectively. We incurred net losses of $23.3 million and $10.3 million in 2008 and 2009, respectively, and had net income of $51.7 million in 2010.

We operate and manage our business as a single segment.

Industry Demand

The solar power market grew rapidly in the past several years. During that period, our business and revenue growth were primarily driven by industry demand and our ability to retain existing customers, attract new customers and expand our manufacturing capacity at the same time. According to Solarbuzz, the global solar power market, as measured by annual volume of modules delivered to installation sites, grew at a CAGR of 79.4% from approximately 1.8 gigawatts, or GW, in 2006 to approximately 18.2 GW in 2010. Under the lowest of three different projections, Solarbuzz expects the annual volume of modules delivered to installation sites may further increase to 24.0 GW in 2015, but global solar power industry revenue may decrease from $82.1 billion in 2010 to $61.1 billion in 2015 while market demand growth is partially offset by the market price declines. According to a Solarbuzz forecast named “Green World”, the moderate one of three possible scenarios, annual volume of modules delivered to installation sites may further increase to approximately 36.4 GW in 2015, and global solar power industry revenue may increase from $82.1 billion in 2010 to $96.2 billion in 2015.

We believe that the following factors have driven and may continue to drive the growth of the solar power industry in the long run as projected by the Solarbuzz “Green World” forecast:

• government incentives for solar power;

• growing demand for electricity, supply constraints and desire for energy security; and

• growing awareness of the advantages of solar power.

In the fourth quarter of 2008 and the first quarter of 2009, the global solar power industry experienced a precipitous decline in demand due to decreased availability of financing for downstream buyers of solar power products as a result of the global economic crisis. During the same period, increased manufacturing capacity combined with decreased demand caused a decline in the prices of solar power products. The demand for solar power products is also influenced by macroeconomic factors such as the global economic downturn, the supply and prices of other energy products, such as oil, coal and natural gas, as well as government regulations and policies concerning the electric utility industry. A decrease in oil prices, for example, may reduce demand for investment in alternative energy. The global economic downturn, which may affect the availability of financing, may also contribute to decreased sales and shipments of solar power products and the slowdown of the large solar project market segments. Pleases see “Item 3. Key Information — D. Risk Factors” for discussions of the risks related to industry demand for solar power products.

We believe that the near-term growth of the market for on-grid applications depends in large part on the availability and size of government subsidies and economic incentives. Today, the cost of solar power substantially exceeds the cost of power provided by the electric utility grid in many locations, when upfront system costs are factored into cost per kilowatt. As a result, governmental bodies in many countries, most notably China, Germany, Italy, Japan, Spain, France and the United States, have provided subsidies and economic incentives to reduce dependency on non-renewable sources of energy. These subsidies and economic incentives have come in the form of capital cost rebates, feed-in tariffs, tax credits and other incentives to end users, solar product distributors, system integrators and manufacturers of solar power products.

The demand for our solar power products is affected significantly by government subsidies and economic incentives in our targeted or potential markets. According to Solarbuzz, Germany had the largest solar power market in 2010, with a market size of 7.74 GW, which accounted for 42.5% of the global solar power market demand in 2010. Italy and Spain had a market size of 3.74 GW and 0.38 GW, respectively, and accounted for 20.5% and 2.1%, respectively, of the global solar power market demand in 2010. At the beginning of 2010, the German government reduced solar feed-in tariffs by 9%. Due to the strong growth in 2009, the German government had decided in early 2010 to implement additional tariff cuts in July and October of 2010, resulting in a total decline of approximately 16% in feed-in tariffs, according to Solarbuzz. Despite this severe reduction in feed-in tariffs rates, the German market soared to 7.74GW in 2010, which triggered another tariff cut of 13% at the beginning of 2011, according to Solarbuzz. The rise of the Italian market in 2010 was largely due to a generous national feed-in-tariff program in combination with the country’s excellent insolation conditions, also from the Italian government’s aim to increase the country’s rate of final electricity consumption from renewable resource to 33% by 2020, according to Solarbuzz. The Spanish market increased

49

significantly in 2010, and this surprising 2010 market rebound result was a function of quota allocations made in 2009 that had to be installed and registered within their 12 months deadline in order to qualify for subsidy terms, according to Solarbuzz. Reductions in, or eliminations of, subsidies and economic incentives for on-grid solar energy applications could result in decreased demand for our products and cause our revenues to decline.

In March 2009, the Chinese government announced new rules to support solar power applications in rural and remote areas, which would allow for meaningful development of the solar power market in China. The Chinese government offers subsidies to assist construction of building integrated solar power applications in urban and remote areas, establishment of the technical standards on the installation of solar power products on buildings, as well as integration and promotion of key universal solar power building technologies. According to the rules, projects with more than 50 Kilowatts and a conversion efficiency of their monocrystalline solar panels of higher than 16% are eligible to receive the subsidies. Priority will be given to the usage of solar modules for building integrated solar power projects and grid-type projects, as well as projects for public buildings. On July 16, 2009, Chinese government issued another Notice on Implementation of Demonstration Project of Golden Sun to support the promotion of photovoltaic generation in China. Under this notice, the photovoltaic projects which meet certain requirements will be provided with subsidies. In August 2009, the Chinese government issued the Report on the Work of Dealing with Climate Change, or the Report, and the Standing Committee of National People’s Congress of China issued the Resolutions on Making Active Responses to Climate Change, or the Resolutions. According to the Report and the Resolutions, the renewable energy use including solar power is encouraged and shall be expanded. We believe that some of our customers may be benefited by these incentives, which may in turn affect their demand for our products.

Availability, Price and Quality of Silicon Raw Materials

Silicon wafers are the most important raw material from which our solar cells are made. To manufacture silicon wafers, polysilicon is melted and processed into crystalline silicon ingots, which are then sliced into wafers. The procurement costs of silicon raw materials have accounted for more than half of our cost of revenues since we began our commercial production of solar cells in August 2005. Fluctuation in the price of polysilicon have in the past impacted our production costs and our cost of revenues and net income. According to Solarbuzz, the average initial price range of long-term polysilicon supply contracts narrowed to $52 – $57 per kilogram in the fourth quarter of 2010 from $50 to $60 per kilogram in the fourth quarter of 2009, and the spot price for solar grade polysilicon maintained a level of around $55 per kilogram by the beginning of 2010 compared to the prices of $45 to $65 per kilogram in the fourth quarter of 2009, but spiked dramatically to above $65 per kilogram by the end of third quarter of 2010, and further increased to $80 per kilogram in the fourth quarter of 2010. Spot price softened to around $70 per kilogram by the end of the first quarter of 2011, according to Solarbuzz.

We purchase silicon wafers from various suppliers, most of which are wafer manufacturers located in China. We also historically procured polysilicon from various suppliers, and outsource the production of silicon wafers from these polysilicon raw materials under toll manufacturing arrangements with third parties. Toll manufacturing is a type of contract manufacturing frequently used in the solar power industry, in which part of the manufacturing process is outsourced to qualified third parties, or toll manufacturers. Sometimes, we also sold polysilicon raw materials to wafer manufacturers and purchased silicon wafers from them under buy-and-sell arrangements. Due to the industry-wide shortage of silicon raw materials experienced during the past few years, we purchased silicon raw materials using short-term and long-term contracts from a limited number of international and domestic suppliers. Some agreements provide for firm purchase commitments and fixed pricing or pricing adjustable in a relatively small range. From the fourth quarter of 2008 to mid-2009, the price of silicon raw materials decreased precipitously due to the excess supply of silicon raw materials resulting from a slowed global solar power market growth. In light of such excess supply, we have sought to re-negotiate with our long-term supply partner in regard to certain long term supply contracts signed in 2008. In February 2011, in order to secure long-term supply of silicon wafer while maintaining ability to keep the price at the market level, we entered into a 6-year contract with GCL-Poly. The agreement contains a clause for a price adjustment mechanism based on wafer market price. Given the current wafer price environment, we also seek to exert greater control over incoming wafer quality while establishing stable and long-term relationships with high quality suppliers.

50

Historically, given the state of the industry, suppliers of silicon raw materials typically required customers to make payments in advance of shipment. Our suppliers generally required us to make a prepayment at a certain percentage of the order value prior to shipping. Due to the relative oversupply of polysilicon, prepayment as a percentage of the entire contract has been reducing. In 2010, most of our suppliers granted us credit terms under their contracts with us. However, our purchases of silicon raw materials may continue to require us to make certain working capital commitments. We are required to manage our borrowings and equity contributions to support our raw material purchases.

Manufacturing Capacity

In order to capture the market opportunity for our solar power products, we have expanded our manufacturing capacity. When the market demand for solar cells exceeded supply, increased capacity had a significant effect on our results of operations, by allowing us to produce and sell more solar cell products generating higher revenues, and by lowering certain manufacturing costs resulting from economies of scale. In June 2005, we completed our first solar cell manufacturing line with a manufacturing capacity of 32 MW per year, and we started generating revenues from the first line in August 2005. We completed our second to sixth solar cell manufacturing lines and started generating revenues from these lines in 2006. We further installed our seventh to tenth solar cell manufacturing lines in December 2008. In 2010, we installed another three solar cell manufacturing lines, increasing our total number of solar cell manufacturing lines to 13. As a result of our acquisition of SST and NRE, as of December 31, 2010, we had an aggregate annual module production capacity of 480 MW. In 2008, the shipment of our solar power products amounted to 107.2 MW, including 100.4 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 2.6 MW of modules sold. In 2009, the shipment of our solar power products amounted to 194.0 MW, including 181.5 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 8.3 MW of modules sold. In 2010, the shipment of our solar power products amounted to 347.8 MW, including 277.2 MW of solar cells sold, 3.4 MW solar cell and modules processed under OEM arrangements and 67.2 MW of modules sold. We had net revenues of $350.9 million, $284.9 million and $517.2 million in 2008, 2009 and 2010, respectively. We incurred net losses of $23.3 million and $10.3 million in 2008 and 2009, respectively, and had net income of $51.7 million in 2010.

When the global supply of solar power products exceeds the global demand due to excess production capacity, global economic downturn or other reasons, we may not be able to fully utilize our manufacturing capacity due to declined demand for our products. As we incur fixed costs associated with our facilities and equipment whether they are being utilized, operating at less than full utilization will result in expenses without corresponding revenue, which will reduce our operating margins.

As of December 31, 2010, we had 13 solar cell manufacturing lines with an aggregate manufacturing capacity of 404 MW per year, assuming the use of 156-millimeter monocrystalline silicon wafers. Our actual output of solar cells depends on the size of the silicon wafers that we use. Historically, we have used a mix of monocrystalline and multicrystalline silicon wafers, each in sizes of 125 millimeters and 156 millimeters.

Pricing of Our Solar Power Products

Solar Cells

Solar cells are priced based on the number of watts of electricity they can generate and on their conversion efficiency. Pricing per watt of solar cells is principally affected by manufacturing costs per watt, comprising of primarily the cost of silicon wafers, the overall market demand for solar cells, and some other factors, such as the exchange rate. Increased economies of scale and process technology advancements in the past resulted in a steady reduction in manufacturing costs and the price per watt of solar cells. However, since 2004, price per watt of solar cells began rising gradually due to rapid demand growth worldwide and the resulting shortages of silicon raw materials. Following several years of increases, prices of solar cells declined gradually in early 2007 mainly due to decreases in subsidies or feed-in tariffs in major end-markets of solar power products, such as Germany, as well as increased production output around the world. From the third quarter of 2007, average selling prices of our solar cells have increased due to increasing demand for solar power products and the appreciation of the Renminbi. In the fourth quarter of 2008 and the first quarter of 2009, the global solar power industry experienced a precipitous decline in demand due to decreased

51

availability of financing for downstream buyers of solar power products as a result of the global economic crisis. During the same period, increased manufacturing capacity combined with decreased demand contributed to a decline in the average selling price of solar power products. The demand for solar power products is influenced by macroeconomic factors such as the global economic downturn, the supply and prices of other energy products, such as oil, coal and natural gas, as well as government regulations and policies concerning the electric utility industry. Although global demand began to recover from the second half of 2009, increasing costs of raw materials and expanded manufacturing capacity in the industry continued to cause pricing pressure of our solar power products.

We determine the power output of our solar cells based on their size and measured conversion efficiencies. We determine the price per watt of our solar cells based on the prevailing market prices when we enter into sales contracts with our customers or when our customers place purchase orders with us, taking into account the size of the contract or the purchase order, the strength, history and prospects of our relationship with the customer and our costs. Most of our customers pay premiums over the price of cells with normal conversion efficiency such as the standard P- type cells, for our high conversion efficiency cells such as the selective emitter solar cells, due to their higher conversion efficiency.

The average selling prices of our solar cells slightly decreased from $1.36 per watt in 2009 to $1.35 per watt in 2010, due primarily to decreased price of silicon raw materials. If demand for solar cell products declines and the supply of solar cell products continues to grow, the average selling price of our solar cells will be materially and adversely affected. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Company and Our Industry — Volatile market and industry trends, in particular, the decline in demand for solar power products and continued downward pressure on the prices of our products will reduce our revenues and profitability” for more details.

Solar Modules

Solar modules are priced based on the number of watts of electricity they generate as well as the market price per watt for solar modules. We price our standard solar modules based on the prevailing market prices at the time we enter into sales contracts with our customers or our customers place their purchase orders with us, taking into account the size of the contract or the purchase order, the strength and history of our relationship with each customer, and our silicon raw materials costs or our costs to purchase solar cells. The average selling price per watt of our solar modules was $1.92 in the last two months of 2010. If demand for solar module products declines and the supply of solar module products continues to grow, the average selling price of our solar modules will be materially and adversely affected.

Pace of Advancement in Process Technologies

Our cell products are priced based on the number of watts of electricity they can generate. Process technologies advancement is important because it helps increase conversion efficiencies of solar cells and the resultant number of watts of electricity solar cells can generate, thereby generating higher revenues per solar cell, and helps reduce the manufacturing cost of solar cells per watt. As a result, solar cell manufacturers, ourselves included, are continuously developing advanced process technology for large-scale manufacturing.

In the fourth quarter of 2007, we commenced commercial production of selective emitter cells, an improved version of the P-type solar cells that most solar cell manufacturers produce. We began pilot production of HP solar cells during the same quarter. In December 2008, we installed four new solar cell lines for the production of selective emitter cells. These four new lines are producing selective emitter cells with performance similar to those from the first line which produces selective emitter solar cells. In 2010, we installed three HP solar cell lines in the existing facilities.

In 2010, our research and the production management teams have made a concerted effort to improve the performance of our standard crystalline solar cells. We have reduced the wafer-cell non-silicon cost to a new low level of $0.20 per watt in the fourth quarter of 2010 while simultaneously improved the cell efficiency. In addition, our research team continued to focus on the development of advanced process technology for manufacturing other new products, such as Quasar-type solar cells.

Seasonality of Our Operations

We believe that industry demand for solar power products may be affected by seasonality. Demand tends to be lower during the winter season from December to February, primarily because adverse weather conditions in certain regions make installations of solar power systems more difficult. Furthermore, as there are fewer working days for our China-based customers during Chinese New Year holidays, usually in January or February, our sales volumes and revenues tend to be lower during these periods. In addition, the prices of silicon raw materials also tend to decrease during such periods.

Overview of Financial Results

Net Revenues

Our net revenues are net of value-added tax. Factors affecting our net revenues include average selling price per watt, unit volume sold and product demand for our solar power products. In addition to sale of solar cells and modules, in 2010 we derived revenues from selling silicon raw materials under our buy-and-sell arrangements with silicon wafer manufacturers. Before we acquired the two module manufacturers in November 2010, we also outsource to third parties the manufacturing of solar modules from our solar cells or purchase solar modules from third parties, and sell these solar modules to our customers.

In 2008, 2009 and 2010, non-related party customers contributing 10% or more of our total net sales accounted for approximately 33%, 11% and nil of our total net revenues, respectively. Such decrease in percentage in 2010 is due to our strategy to sell our solar cells to SST and NRE which were acquired by us in November 2010, upon our expansion into downstream solar power business. SST and NRE contributed 23.6% and 23.2% of our net revenues in 2010 prior to the acquisition, respectively.

The following table sets forth by region our total net revenues derived from sales of our products for the periods indicated:

Cost of Revenues and Operating Expenses

The following table sets forth our cost of revenues and our operating expenses as a percentage of our total net revenues for the periods indicated.

	Year Ended December 31,
	2008			2009			2010
Cost of revenues		95.6	%		94.2	%		82.2	%
Operating expenses:
Selling and marketing expenses		1.1			1.0			1.1
General and administrative expenses		4.8			8.6			3.4
Research and development expenses		0.5			1.5			0.6
Total operating expenses		6.4	%		11.1	%		5.1	%

Our cost of revenues decreased significantly in 2010 as a percentage of our total net revenues in 2010 primarily due to the decreased price of silicon raw materials and our reduced non-silicon cost.

Our operating expenses include general and administrative expenses, selling and marketing expenses and research and development expenses.

Our total operating expenses as a percentage of our total net revenues was 6.4%, 11.1% and 5.1% in 2008, 2009 and 2010, respectively. Our total operating expenses in 2009 as a percentage of our total net revenues was higher than that of 2008 and 2010 because our reserve in 2009 included the proposed settlement of the 2007 shareholder class action of $1.1 million and allowance for doubtful accounts receivable of $7.3 million. In addition, we incurred more material costs consumed in our research and development activities in 2009.

Cost of Revenues

Our cost of revenues consists primarily of:

• Raw materials cost. Silicon raw materials, primarily in the form of silicon wafers, comprise a substantial majority of our cost of revenues. In addition to silicon raw materials, raw materials involved in our production also include metallic pastes, tempered glass, ribbon, laminate material (EVA,TPT), junction box, and aluminum frame. Since expanding into the module business, we have been purchasing solar cells from our in-house cell manufacturing division as well as other third-party suppliers for our module production.

• Direct labor cost. Direct labor costs include salaries and benefits for manufacturing personnel. We expect direct labor costs to increase as we hire additional manufacturing personnel as we expand our production.

• Overhead. Overhead costs include maintenance, utilities such as electricity and water used in manufacturing, and other support expenses associated with the manufacturing.

• Depreciation and amortization of manufacturing facilities and equipment. Due to our capacity expansion, our depreciation and amortization expenses have increased. We expect depreciation to increase in absolute terms in the near future following the expansion of our manufacturing capacity.

• Warranty costs. With respect to solar cell sales made with contractual warranty provisions, we accrue 0.5% of our net revenues as warranty costs at the time revenue is recognized. Our sales contracts concluded after December 2006 do not contain warranty provisions, which we believe is in line with the practice of other solar cell manufacturers in China. We do not expect to enter into solar cell sales contracts with warranty provisions in the future. We still accrue warranty costs for deliveries of solar cells under the contracts concluded before December 2006. With respect to solar modules, which are typically sold with a five-year warranty for defects in material and workmanship and a minimum power output warranty of up to 25 years following the date of purchase, we accrue

54

1.0% of our net revenues generated from module sales based on our competitors’ accrual history and industry practice. We expect warranty costs to increase in absolute terms as module sales will account for a larger portion of our net revenues as we expand into downstream solar power business.

• Shipping and handling costs. Cost of revenues also includes shipping and handling costs of products bought from suppliers or sold to customers.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and benefits for our administrative and finance and human resources personnel, expenses associated with our administrative offices, professional advisory fees and other compliance-related costs, bad debt provision as well as depreciation of equipment used for administrative purposes. Pursuant to PRC law, our board of directors has the discretion to allocate a portion of our after-tax profit to staff welfare and bonus funds, which may not be distributed to equity owners.

General and administrative expenses account for the largest part of our operating expenses. In 2008, 2009 and 2010, our general and administrative expenses were $16.8 million, $24,5 million and $17.5 million, respectively. In 2009, our general and administrative expenses were higher than those in 2008 and 2010 primarily due to our reserve in 2009 for the proposed settlement of the 2007 shareholder class action of $1.1 million and allowance for doubtful accounts receivable of $7.3 million. In 2008, 2009 and 2010, we also recorded share-based compensation expenses of $3.2 million, $1.3 million and $0.5 million, respectively, in connection with the grants of share options and restricted shares to certain employees.

Selling and Marketing Expenses

Selling and marketing expenses consist primarily of post-sale service expenses, sales employee salaries, travel and entertainment expenses, freight expenses, and other sales and marketing expenses.

We expect that our selling and marketing expenses will increase in absolute terms in the near term as we increase our sales efforts, hire additional sales personnel, develop new markets and initiate additional marketing programs to establish our brand name.

Research and Development Expenses

Research and development expenses consist primarily of cost of raw materials used in our research and development activities, salaries and benefits for research and development personnel, and prototype costs and depreciation of equipment related to the design, development, testing and enhancement of our products and manufacturing processes. We expect our research and development expenses to increase as we purchase more raw materials to be used in our research and development activities, and plan to hire additional personnel for the research and development of our process technology.

Share-based Compensation Expenses

In 2008 and 2009, we entered into option award agreements pursuant to our first share incentive plan. Under these option award agreements, we had outstanding options to purchase 965,214 ordinary shares as of December 31, 2010. We also entered into two restricted share award agreements pursuant to our second share incentive plan. As of December 31, 2010, no restricted share was outstanding under these restricted share award agreements. See Item 6, “Directors, Senior Management and Employees — Compensation of Directors and Executive Officers — Share Incentive Plan.” In 2008, 2009 and 2010, we recorded share-based compensation expenses of $3.2 million, $1.3 million and $0.5 million, respectively, in connection with the grants of share options and restricted shares to certain employees. Changes in the amount of share-based compensation will primarily affect our general and administrative expenses, reported net income and earnings per share.

We are required to recognize share-based compensation as compensation expense in our statement of operations based on the fair value of equity awards on the grant date, with the compensation expense recognized over the period in which the recipient is required to provide service in exchange for the award (usually the vesting period). We are also required to adopt a fair value-based method of measuring the compensation expense related to share-based compensation. We record share-based compensation expenses for

55

the fair value of the options and restricted shares at the grant date. We recognize such share-based compensation expenses over the grant recipient’s requisite service periods.

As of December 31, 2010, there was $0.08 million in total unrecognized compensation expense related to unvested share-based compensation arrangements granted under the plan, which is expected to be recognized over a weighted-average period of 0.57 years.

Taxation

Under the current laws of the Cayman Islands and the British Virgin Islands, we and Sunergy BVI are not subject to tax on income or capital gain. Additionally, dividend payments made by us and Sunergy BVI are not subject to withholding tax in those jurisdictions.

Under the current Hong Kong Inland Revenue Ordinance, Sunergy Hong Kong is subject to Hong Kong profit tax at a rate of 17.5% as of March 31, 2008 and 16.5% effective from April 1, 2008 on its taxable income generated from operations in Hong Kong. Additionally, payments of dividends by Sunergy Hong Kong to us are not subject to any Hong Kong withholding tax.

The New EIT Law and the New EIT Law Implementation Rules provides that enterprises established under the laws of foreign countries or regions whose “de facto management bodies” are located within the PRC are considered PRC resident enterprises and will be subject to the PRC enterprise income tax at the rate of 25% on their worldwide income. Under the New EIT Law Implementation Rules, a “de facto management body” is defined as “establishments that carry out substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc. of an enterprise.” If we are treated as PRC resident enterprises for PRC tax purposes, we will be subject to PRC enterprise income tax on our worldwide income at the 25% tax rate, which would have an impact on our effective tax rate. Additionally, under such circumstances that Sunergy Hong Kong is also treated as a PRC resident enterprise, dividends distributed from our PRC subsidiaries to Sunergy Hong Kong and ultimately to us could be exempt from withholding tax, and dividends from us to our foreign investors would be subject to a withholding tax at 10%, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced withholding arrangement.

PRC Enterprise Income Tax

Prior to January 1, 2008, a foreign-invested enterprise in China was typically subject to enterprise income tax at a statutory rate of 33%, which comprised 30% national income tax and 3% local income tax. Sunergy Nanjing, a foreign-invested enterprise engaged in a manufacturing business and established in Nanjing, which is within a coastal economic zone, was entitled to a preferential enterprise income tax rate of 24% before January 1, 2008. As a wholly foreign owned enterprise engaged in a manufacturing business, Sunergy Nanjing was also entitled to two years of exemption followed by three years of 50% deduction starting from its first profitable year which was 2006. On March 16, 2007, the National People’s Congress issued the New EIT Law, under which foreign-invested enterprises and domestically-owned companies would be subject to enterprise income tax at a uniform rate of 25%. On December 6, 2007, the Congress also promulgated the New EIT Law Implementation Rules. Both the New EIT Law and the New EIT Law Implementation Rules became effective on January 1, 2008. On December 26, 2007, State Council of China promulgated the Circular. Under the New EIT Law, the New EIT Law Implementation Rules and the Circular, enterprises which were established and already enjoyed preferential income tax treatments before March 16, 2007 will continue to enjoy them (i) in the case of preferential tax rates, for a period of five years from January 1, 2008, and the enterprises which previously enjoy the tax rate of 24% shall be subject to the tax rate of 25% in 2008, and (ii) in the case of preferential tax exemption or reduction for a specified term, until the expiration of such term, or 2012, whichever is earlier. However, the Circular also prescribes that if the above transitional relief of enterprise income tax overlaps with the preferential treatments provided by the New EIT Law, an enterprise may choose the more favorable treatment, and shall not enjoy both. The treatment cannot be changed once it is chosen.

On April 14, 2008, the Ministry of Finance, the Ministry of Science and Technology and the State Administration of Taxation jointly promulgated the Recognition Measures. Pursuant to the New EIT Law, the New EIT Law Implementation Rules and the Recognition Measures, HNTE is eligible for a preferential tax

56

rate of 15%. On October 21, 2008, Sunergy Nanjing obtained a HNTE certificate with a three-year validity term, from 2008 to 2010. Therefore, Sunergy Nanjing is eligible for a 15% preferential tax rate during the above period.

Based on the Circular, the management chooses to enjoy the transitional relief, i.e. 12.5% from 2008 to 2010, for Sunergy Nanjing. Sunergy Nanjing was in a tax loss position under PRC tax law in 2004, 2005, 2007, 2008 and 2009, and thus was not subject to any enterprise income tax during these periods. Sunergy Nanjing is subject to such enterprise income tax in 2010.

Sunergy Shanghai was established in November 2007 and its applicable enterprise income tax rate is 25%. Sunergy Shanghai did not have substantive operations and had incurred minimal non-operating related losses in 2007, 2008, 2009 and 2010.

SST was acquired in November 2010. It obtained the HNTE certificate in 2009, with a valid period between 2009 and 2011, and thus is eligible for a 15% preferential tax rate during this period.

NRE was acquired in November 2010 and its applicable enterprise income tax rate is 25%.

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (a) the reported amounts of our assets and liabilities, (b) the disclosure of our contingent assets and liabilities at the end of each fiscal period and (c) the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and reasonable assumptions, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

When reviewing our financial statements, you should consider (a) our selection of critical accounting policies, (b) the judgment and other uncertainties affecting the application of such policies and (c) the sensitivity of reported results to changes in conditions and assumptions. We believe the following accounting policies involve the most significant judgment and estimates used in the preparation of our financial statements.

Revenue Recognition

Sales of solar cells and modules are recorded when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is reasonably assured. We sell our solar power products at agreed upon prices to our customers, which reflect prevailing market prices. Our considerations for recognizing revenue are based on the following:

• Persuasive evidence that an arrangement (sales contract) exists between a willing customer and us that outlines the terms of the sale (including customer information, product specification, quantity of goods, purchase price and payment terms). Customers do not have any general rights of return but may be allowed to exchange for goods that are not defective but may not meet certain minor specifications such as color or sizes of the products for a 30 to 45 day period. We have recorded the estimated replacement costs, which have been immaterial for all periods as a result of the product exchanges in cost of revenue upon the recognition of revenue.

• Our price to the customer is fixed and determinable as specifically outlined in the sales contract.

• For customers to whom credit terms are extended, we assess a number of factors to determine whether collection from them is probable, including past transaction history with them and their credit-worthiness. All credit extended to customers is pre-approved by management. If we determine that collection is not reasonably assured, we defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment.

57

Allowance for Doubtful Accounts

We conduct credit evaluations of customers and generally do not require collateral or other security from them. We establish an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. We generally do not require collateral or other security interests from our customers when we grant them credit. However, we maintain a reserve for potential credit losses and such losses have historically been within our expectations. We raise an allowance for doubtful accounts primarily based on the age of the receivables or prepayments and other factors like the length of time receivables are passing due, previous loss history and the counterparty’s current ability to fulfill its obligation. In 2009, we recorded $7.3 million allowance for doubtful accounts, primarily attributable to the doubtful accounts in connection with our sales to a major client of us in 2008 due to the worsening financial condition of this client.

With respect to advances to suppliers, our suppliers are primarily suppliers of silicon raw materials. We perform ongoing credit evaluations of our suppliers’ financial conditions. We generally do not require collateral or security against advances to suppliers.

Inventories

Our inventories are stated at the lower of cost or market value. The valuation of inventory requires us to estimate excess and slow moving inventory. The determination of the value of excess and slow moving inventory is based upon assumptions of future demands and market conditions. If actual market conditions are less favorable than those projected by management, inventory write-downs may be required. We routinely evaluate quantities and value of our inventories in light of current market conditions and market trends, and record write-down against the cost of inventories for a decline in net realizable value. Inventory write-down charges establish a new cost basis for inventory. In estimating obsolescence, we estimate future market demand by referring to our backlog sales orders and our historical inventory turnover ratio. We estimate sales prices for the next quarter through our market analysis. Market conditions are subject to change and actual consumption of inventories could differ from forecasted demand. Furthermore, spot prices of polysilicon are primarily a result of market supply and demand. Our management continually monitors the changes in the purchase price paid for polysilicon, including prepayments to suppliers. Our products have a long life cycle and obsolescence has not historically been a significant factor in the valuation of inventories.

Impairment of Long-lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When these events occur, we measure impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we recognize an impairment loss based on the fair value of the assets. The determination of fair value of the long lived assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future. This analysis also relies on a number of factors, including changes in strategic direction, business plans, regulatory developments, economic and budget projections, technological improvements, and operating results. Any write-downs would be treated as permanent reductions in the carrying amounts of the assets and an operating loss would be recognized. We identified certain long-lived assets that were no longer actively used due to obsolete technology or poor physical conditions as of December 31, 2009, resulting in a loss of $0.8 million.

Business combination

Our consolidated financial statements reflect the results of an acquired business after the completion of the acquisition. We account for business combinations using the purchase method of accounting, which requires that most assets acquired and liabilities assumed be recorded at the date of acquisition at their fair values. Any excess of the purchase price over the assigned values of the net assets acquired is recorded as goodwill.

58

The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact our results of operations. There are several methods that can be used to determine fair value. For intangible assets, we typically use the income method. This method starts with our forecast of all of the expected future net cash flows. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash-flow streams. Some of the more significant estimates and assumptions inherent in the income method or other methods include:

• amount and timing of projected future cash flows;

• amount and timing of projected costs to develop commercially viable products and services;

• discount rate selected to measure the risks inherent in the future cash flows; and

• assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of (1) any technical, legal, regulatory or economic barriers to entry and (2) expected changes in standards of practice for indications addressed by the asset.

Determining the useful life of an intangible asset also requires judgment, as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives.

Goodwill Impairment

Goodwill is required to be tested for impairment at least annually or more frequently if events or changes in circumstances indicate that these assets might be impaired. If we determine that the carrying value of our goodwill has been impaired, the carrying value will be written down.

To assess potential impairment of goodwill, we perform an assessment of the carrying value of the reporting unit at least on an annual basis or when events and changes in circumstances occur that would more likely than not reduce the fair value of the reporting unit below its carrying value. If the carrying value of reporting unit exceeds its fair value, we would perform the second step in our assessment process and record an impairment loss to earnings to the extent the carrying amount of the reporting unit exceeds its implied fair value. We estimate the fair value of the reporting unit through internal analysis and external valuations, which utilize income and market valuation approaches through the application of capitalized earnings and discounted cash flow. These valuation techniques are based on a number of estimates and assumptions, including the projected future operating results, appropriate discount rates and long-term growth rates. The significant assumptions regarding our future operating performance are revenue growth rates, discount rates and terminal values. If any of these assumptions changes, the estimated fair value of the reporting unit will change, which could affect the amount of goodwill impairment charges, if any. We have not recognized any impairment charge in 2010. We are currently not aware of any impairment charge of the goodwill.

Warranty Costs

Historically, some of our sales contracts with overseas customers provided for a 10- or 20-year warranty for the performance of our solar cells against declines in certain technical specifications, primarily the minimum power generation capacity specified at the time of delivery. Since the beginning of 2007, we have aborted such warranty terms in solar cell sales contracts. We also sell our module products to customers along with a warranty on the performance of solar module products at certain levels of conversion efficiency for an extended period. Our solar modules are typically sold with a warranty up to 25 years against specified declines in the initial minimum power generation capacity at the time of sale. In addition, we provided warranty for our solar modules against defects in materials and workmanship for a period of five years from the date of sale. We, therefore, maintain warranty reserves (recorded as accrued warranty costs) to cover potential liabilities that could arise from these warranties. We accrue the estimated costs of warranties at 0.5% of our solar cell sales made with warranty provisions and 1.0% of our solar module sales, respectively, and include that amount in our cost of revenue. Because we are a relatively new company, we have a limited warranty claim period. We also engage in product quality assurance programs and processes, including monitoring and evaluating the quality of suppliers, in an effort to ensure the quality of our products and reduce our warranty exposure. As we have not experienced significant warranty claims to date in connection with declines of the power generation capacity or other technical specifications of our solar cells or solar

59

modules, we estimate our warranty costs based on our actual historical cost data, competitor data and academic research which are reviewed by our quality review staff. Although we conduct quality testing and inspection of our solar cell products, our solar cell products have not been tested in an environment simulating the up to 20-year warranty periods. We acknowledge that such estimates are subjective, and we will continue to analyze our claim history and the performance of our products compared to our competitors and academic research to determine whether our accrual is adequate. Actual warranty costs are accumulated and charged against accrued warranty liability. Our warranty obligation will be affected not only by our product failure rates, but also by costs incurred to repair or replace failed products as well as any service delivery costs incurred in correcting a product failure. If our actual product failure rates, material usage or service delivery costs differ from our estimates, we will need to prospectively revise our estimated warranty liability accrual rate.

Valuation of Share-based Compensation

We record share-based compensation expense based on the fair value of the options and other awards on the date of grant.

In 2008 and 2009, we granted share options and restricted shares to certain of our employees. We incurred share-based compensation expenses of $3.2 million, $1.3 million and $0.5 million for the years ended December 31, 2008, 2009 and 2010, respectively. We used the binomial option-pricing method to determine the amount of employee share-based compensation expenses. This approach requires us to make assumptions on such variables as share price volatility, expected lives of awards and discount rates. Changes in these assumptions could significantly affect the amount of employee share-based compensation expenses we recognize in our consolidated financial statements. See Item 5, “— Overview of Financial Results — Share-based Compensation Expenses.”

Income Taxes

As required by Accounting Standards Codification 740, “Income Taxes,” we periodically evaluate the likelihood of the realization of deferred tax assets, and reduce the carrying amount of these deferred tax assets by a valuation allowance to the extent we believe a portion will not be realized. We consider many factors when assessing the likelihood of future realization of our deferred tax assets, including our recent cumulative operating experience by taxing jurisdiction, expectations of future taxable income, the carry-forward periods available to us for tax reporting purposes, and other relevant factors. Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits by applying enacted tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. On October 21, 2008, Sunergy Nanjing obtained a HNTE certificate with a three-year validity term, from 2008 to 2010. SST was acquired in November 2010. It obtained the HNTE certificate in 2009, with a valid period between 2009 and 2011, and thus is eligible for a 15% preferential tax rate during this period. NRE was acquired in November 2010 and its applicable enterprise income tax rate is 25%. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities, or the expected timing of their use when they do not relate to a specific asset or liability.

Results of Operations

The following table sets forth a summary, for the periods indicated, of our consolidated results of operations, with each item expressed as a percentage of our total net revenues. Our limited operating history makes the prediction of future operating results very difficult. Period-to-period comparisons of our operating results should not be relied upon as indicative of future performance. Item 3 “Key Information — Risk Factors — Risks Related to Our Company and Our Industry — Our limited operating history may not serve as an adequate measure of our future prospects and results of operations.”

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

Net Revenues.  Our total net revenues increased by $232.3 million, or 81.5%, from $284.9 million in 2009 to $517.2 million in 2010. Our net revenues increased primarily due to an increase in the volume of our solar power product sales.

In 2010, we shipped 347.8 MW of solar power products including 277.2 MW solar cells, 3.4 MW solar cells and modules processed under OEM arrangements and 67.2 MW of solar modules, compared to sales of 194.0 MW of solar power products, including 181.5 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 8.3 MW of modules sold in 2009. The increase in our sales of solar power products was due primarily to the macroeconomic economic conditions and the increase of our available manufacturing capacity and production output resulted from both the expansion of our solar cell production capacity and the acquisitions of module business.

61

Cost of Revenues.  Our cost of revenues increased by $156.6 million, or 58.4%, from $268.3 million in 2009 to $424.9 million in 2010. Our cost of revenues increased primarily due to the increased volume of our solar power product sales, partially offset by the decreased price of silicon raw materials and our reduced non-silicon cost.

Silicon raw materials, primarily silicon wafers, accounted for approximately 80% of our cost of revenue in 2010 compared to 76.6% in 2009 due primarily to the reduced non-silicon cost in 2010. As a percentage of our total net revenues, our cost of revenues decreased from 94.2% in 2009 to 82.2% in 2010.

Gross Profit.  As a result of the foregoing, our gross profit in 2010 increased by $75.7 million to $92.3 million, from $16.6 million in 2009. Our gross margin increased from 5.8% in 2009 to 17.8% in 2010.

Operating Expenses.  Our operating expenses decreased by $5.5 million, or 17.3%, from $31.8 million in 2009 to $26.3 million in 2010. The decrease in operating expenses was primarily due to decreases in general and administrative expenses. As a percentage of our total net revenues, operating expenses decreased from 11.2% in 2009 to 5.1% in 2010.

General and administrative expenses.  Our general and administrative expenses decreased by $7.0 million, or 28.6%, from $24.5 million in 2009 to $17.5 million in 2010. The decrease in our general and administrative expenses was due primarily to our reserve in 2009 for the proposed settlement of the 2007 shareholder class action of $1.1 million and allowance for doubtful accounts receivable of $7.3 million, which was primarily attributable to the doubtful accounts in connection with our sales to a major client of us in 2008 due to the worsening financial condition of this client, partially offset by increased salary and other benefits expenses due to our acquisition of the two module manufacturers in November 2010.

Selling and marketing expenses.  Our selling and marketing expenses increased by $2.6 million, or 89.7%, from $2.9 million in 2009 to $5.5 million in 2010. The increase in our selling and marketing expenses was due primarily to the increase in logistic fee for products delivery and the amortization cost of intangible assets regarding customer relationship incurred by the two module manufacturers we acquired.

Research and development expenses.  Research and development expenses decreased by $1.1 million, or 25%, from $4.4 million in 2009 to $3.3 million in 2010. The decrease in research and development expenses was primarily because we conducted more research and development activities and consumed more raw materials in the research and development activities in 2009 than in 2010.

Interest Expense.  Our interest expenses increased by $1.4 million, or 18.2%, from $7.7 million in 2009 to $9.1 million in 2010. The increase was due primarily to increase in the total amount of bank borrowings.

Interest Income.  Our interest income decreased slightly by $0.4 million, or 25%, from $1.6 million in 2009 to $1.2 million in 2010, due primarily to the decrease of the interest rate applied to certain of our bank deposits.

Change in Fair Value of Derivative.  In 2010, we had a gain on the change in fair value of derivative of $2.9 million, compared to a gain on the change in fair value of derivative of $8.0 million in 2009. The higher gain in fair value of derivative in 2009 was mainly attributable to the termination of the embedded foreign currency derivative instruments in connection with the termination of one of our long term supply contract in September 2009.

Net Other Income (Expense).  In 2010, we recorded net other expenses of $3.7 million, due primarily to foreign exchange loss of $5.1 million as a result of the depreciation of Euros and U.S. Dollars. In 2009, we recorded net other income of $2.1 million, due primarily to the gain of $2.2 million from the repurchases of the convertible senior notes, which was partially offset by the foreign exchange loss of $0.5 million in the same year. We did not repurchase any of our outstanding convertible senior notes during 2010.

Net Income (Loss).  As a result of the foregoing, we achieved a net income of $51.7 million in 2010, compared to net loss of $10.3 million in 2009.

Year Ended December 31, 2009 Compared to Year Ended December 31, 2008

Net Revenues.  Our total net revenues decreased by 18.8%, from $350.9 million in 2008 to $284.9 million in 2009. Our net revenues decreased primarily due to a decrease in the average selling price of

62

the solar power products we sold as a result of the impact on pricing caused by the macroeconomic conditions and over-supply of solar power products experienced during 2009. Our average selling price for solar cells decreased from $3.32 per watt in 2008 to $1.36 per watt in 2009.

In 2009, we shipped 194.0 MW of solar power products, including 181.5 MW of solar cells sold, 4.2 MW of solar cells processed under OEM arrangements and 8.3 MW of modules sold, compared to sales of 107.2 MW of solar power products, including 4.2 MW of solar cells processed under OEM arrangements and 2.6 MW of solar modules in 2008. The increase in our sales of solar power products was due primarily to the increase of our available manufacturing capacity and production output.

Cost of Revenues.  Our cost of revenues decreased by $67.2 million from $335.5 million in 2008 to $268.3 million in 2009. Our cost of revenues decreased primarily due to the reduced prices of silicon raw materials as a result of the industry wide over supply of polysilicon.

Silicon raw materials, primarily silicon wafers, accounted for approximately 76.6% of our cost of revenue in 2009 compared to 90.2% in 2008 due primarily to the declining wafer spot price in 2009. As a percentage of our total net revenues, our cost of revenues decreased from 95.6% in 2008 to 94.2% in 2009.

Gross Profit.  As a result of the foregoing, our gross profit in 2009 increased by $1.1 million to $16.6 million, from $15.5 million in 2008. Our gross margin increased from 4.4% in 2008 to 5.8% in 2009.

Operating Expenses.  Our operating expenses increased by $9.3 million, from $22.5 million in 2008 to $31.8 million in 2009. The increase in operating expenses was due to increases in general and administrative expenses and research and development expenses. As a percentage of our total net revenues, operating expenses increased from 6.4% in 2008 to 11.1% in 2009.

General and administrative expenses.  Our general and administrative expenses increased by $7.7 million, from $16.8 million in 2008 to $24.5 million in 2009. The increase in our general and administrative expenses was due primarily to the reserve for the proposed settlement of the 2007 shareholder class action of $1.1 million and allowance for doubtful accounts receivable of $7.3 million, which was primarily attributable to the doubtful accounts in connection with our sales to a major client of us in 2008 due to the worsening financial condition of this client, offset in part by a decrease in share based compensation expenses from $3.2 million in 2008 to $1.3 million in 2009.

Selling expenses.  Our selling expenses decreased by $1.0 million from $3.9 million in 2008 to $2.9 million in 2009. The relatively high selling expenses in 2008 were due primarily to compensation we made to certain customer in connection with the quality deficiencies of our solar cells. Selling expenses as a percentage of net revenues decreased slightly from 1.1% in 2008 to 1.0% in 2009.

Research and development expenses.  Research and development expenses increased by $2.5 million from $1.9 million in 2008 to $4.4 million in 2009. The increase in research and development expenses was due primarily to our purchase more raw materials used in our research and development activities, and hiring of additional personnel for the research and development of our process technology.

Interest Expense.  Our interest expenses decreased from $8.5 million in 2008 to $7.7 million in 2009. The decrease was due primarily to a decrease in average interest rate of our short-term bank borrowings.

Interest Income.  Our interest income decreased slightly from $1.7 million in 2008 to $1.6 million in 2009, due primarily to a decrease in average interest rate of our bank deposits.

Change in Fair Value of Derivative.  In 2009, we had a gain on the change in fair value of derivative of $8.0 million, compared to a loss on the change in fair value of derivative of $9.9 million in 2008. The gain was mainly attributable to the termination of the embedded foreign currency derivative instruments in connection with the termination of one of our long term supply contract in September 2009. See “— Critical Accounting Policies — Derivative Financial Instruments” for more details.

Net Other Income (Expense).  In June 2009, we conducted open market repurchase of $4.0 million aggregate principal amount of the convertible senior notes for a total cash consideration of $1.8 million, compared to our repurchase of $6.5 million aggregate principal amount of the convertible senior notes for a

63

total cash consideration of $2.0 million during the fourth quarter of 2008. We recorded the gain of $2.2 million from the repurchases as other income in our consolidated income statement, compared to a gain of $4.5 million in 2008.

In 2009, we recorded net other income of $2.1 million, due primarily to the above gain of $2.2 million from the repurchases of the convertible senior notes, which was partially offset by the foreign exchange loss of $0.5 million in the same year. In 2008, we recorded net other expense of $2.3 million, due primarily to the gain of $4.5 million from the repurchases of the convertible senior notes, which was offset by the foreign exchange loss of $6.9 million in the same year as a result of devaluation of Euro against Renminbi during 2008.

Net Income (Loss).  As a result of the foregoing, we incurred a net loss of $10.3 million in 2009, compared to net loss of $23.3 million in 2008, because the business conditions have been improving from the second quarter of 2009.

B.Liquidity and Capital Resources

Cash Flows and Working Capital

To date, we have financed our operations primarily through cash flows from equity contributions by our shareholders, operations and long-term and short-term borrowings.

In July 2008, we completed an offering of $54.5 million aggregate principal amount of 4.75% convertible senior notes. The notes are convertible at any time prior to the close of business on the third business day immediately preceding the maturity date, unless previously redeemed, at the option of the holders into our ADSs at a conversion price of $12.30 per ADS, subject to certain adjustments. In connection with the convertible senior notes offering, we also offered 4,431,000 ADSs in an ADS borrow facility. During the fourth quarter of 2008, we conducted open market repurchases of the convertible senior notes, and through December 31, 2008, we repurchased $6.5 million aggregate principal amount of the convertible senior notes for a total cash consideration of $2.0 million. In June 2009, we conducted open market repurchases of $4.0 million aggregate principal amount of the convertible senior notes for a total cash consideration of $1.8 million. We did not repurchase any of our outstanding convertible senior notes during 2010.

As of December 31, 2008, 2009 and 2010, we had $94.8 million, $123.9 million and $106.5 million, respectively, in cash and cash equivalents, $97.3 million, $102.5 million and $169.7 million, respectively, in outstanding borrowings. Our cash and cash equivalents primarily consist of cash on hand and demand deposits placed with banks. As of December 31, 2008, 2009 and 2010, $97.3 million, $102.5 million and $139.5 million, respectively, of our outstanding borrowings were due within one year. These borrowings expire at various times throughout the year. Our short-term borrowings outstanding as of December 31, 2008, 2009 and 2010 bore an average interest rate of 7.42%, 5.62% and 5.33%, respectively. We did not have any long-term borrowings as of December 31, 2008 and 2009. We had $30.2 million long-term borrowings as of December 31, 2010, which bore an average interest rate of 3.51%. We have historically been able to repay our borrowings as they became due from capital contributions from our shareholders, proceeds from short-term and long-term borrowings and note offering, and our operating cash flows. See Item 3, “Key Information — Risk Factors — Risks Related to Our Company and Our Industry — We have significant outstanding bank borrowings, and we may not be able to arrange adequate financing when they mature or may encounter other difficulties in maintaining liquidity.”

As of December 31, 2010, approximately $128.4 million of the short-term bank borrowings have been guaranteed Mr. Tingxiu Lu, our chairman, CEEG, a company controlled by Mr. Lu, and Jiangsu CEEG Electrical Equipment Manufacturing Co., Ltd., a company controlled by Mr. Lu. In an agreement between Sunergy Nanjing and CEEG dated December 18, 2006, CEEG had undertaken to guarantee the bank borrowings of Sunergy Nanjing for up to RMB1 billion, subject to adjustment in the event of the material change of CEEG’s credit or operation status, for one year after our initial public offering. In May 2008 and April 2010, Sunergy Nanjing and CEEG signed agreements to further extend the term of the above agreement to May 16, 2010 and further to May 31, 2011.

Historically, we have significant working capital commitments because suppliers of silicon wafers and other silicon-based raw materials require us to make prepayments in advance of shipment. Due to the

64

industry-wide shortage of silicon raw materials in the past several years, working capital and access to financings for the purchasing of silicon raw materials were critical to growing our business. However, due to the relative oversupply of polysilicon, prepayment as a percentage of the entire contract has been reducing. In 2010, most of our suppliers granted us credit terms under their contracts with us. Our advances to suppliers decreased significantly to $0.2 million as of December 31, 2009 from $7.3 million as of December 31, 2008. However, the prepayment increased to $8.5 million as of December 31, 2010 as we increase the prepayment in some of our contracts in order to maintain our relationship and preferential price with qualified suppliers. Depending on the supply and demand situation, going forward, our purchases of silicon raw materials may continue to require us to make certain working capital commitments from time to time as we expand our production.

Inventories, one of the principal components of our current assets, increased from $22.6 million as of December 31, 2009 to $72.3 million as of December 31, 2010 primarily due to the acquisitions of module business.

We generally require customers to make prepayment before delivery. However, depending on their credit history with us, we historically granted our large customers credit terms of 30 to 60 days. Our accounts receivable increased from $15.3 million as of December 31, 2009 to $65.6 million as of December 31, 2010. The increase in our accounts receivable was primarily due to the acquisition of module business.

The following table sets forth a summary of our cash flows for the periods indicated:

	Year Ended December 31,
	2008			2009			2010
	(in thousands)
Net cash generated from operating activities	$	91,954		$	28,965		$	30,752

Cash and cash equivalents at the end of the year	$	94,800		$	123,855		$	106,468

Operating Activities

Operating activities during the year ended December 31, 2010 provided $30.8 million of cash inflow in 2010. Operating cash inflows are largely attributable to revenues derived from the sales of our solar power products. Operating cash outflows are largely attributable to recurring expenditures for raw materials, labor, administration, marketing, and other activities. Changes in the components of our working capital also impact cash flow from operating activities. For the year ended December 31, 2010, our business generated substantial cash inflow as we increased net revenues by 81.5% from $284.9 million in 2009 to $517.2 million in 2010. Our cost of revenues and operating expenses, after deducting non-cash operating items, increased by 56.1% from $279.8 million in 2009 to $436.7 million in 2010. We had a net operating cash outflow in working capital of $33.6 million for the year ended December 31, 2010. The cash outflow in working capital was primarily due to a significant increase in inventories as a result of increased requirement for more silicon raw materials and solar cells in connection with the expansion of production capacity and the expansion to downstream business, and a significant increase in amounts due from related parties as a result of our increased sales of modules to related parties.

Operating activities during the year ended December 31, 2009 provided $29.0 million of cash inflow in 2009. For the year ended December 31, 2009, our business generated substantial cash inflow as we recorded net revenue of $284.9 million. Our cost of revenues and operating expenses, after deducting non-cash operating items, decreased by 17.0% from $337.2 million in 2008 to $279.8 million in 2009. We had a net operating cash inflow in working capital of $27.7 million for the year ended December 31, 2009. The cash inflow in working capital was primarily due to a significant decrease in inventories due to a decreased inventory level and a reduced average price of our inventory, a decrease in prepaid expenses and other current assets, a decrease in advances to suppliers as a result of the improved silicon raw material supply conditions, an increase in accounts payable due to increased payment periods in connection with the purchases of silicon

65

raw materials, partially offset by an increase in amounts due from related parties and accounts receivables due to the longer credit term we granted to our customers in respect of sales of our products.

Operating activities during the year ended December 31, 2008 provided $92.0 million of cash inflow in 2008. For the year ended December 31, 2008, our growing business generated substantial cash inflow as we increased net revenues by 49.4% from $234.9 million in 2007 to $350.9 million in 2008. Our cost of revenues and operating expenses, after deducting non-cash operating items which included inventory write-down of $11.8 million, increased by 48.5% from $227.1 million in 2007 to $337.2 million in 2008. We had a net operating cash inflow in working capital of $88.0 million for the year ended December 31, 2008. The cash inflow in working capital was primarily due to a significant decrease in advances to suppliers as a result of improved silicon raw material supply conditions, a decrease in accounts receivable as we received payment for deliveries previously made, an increase in accounts payable due to increased payment periods in connection with the purchases of silicon raw materials, partially offset by an increase in inventories as a result of increased requirement for more silicon raw materials in line with the expansion of production capacity, and a decrease in advances from customers as we lowered the prepayment ratio and not requesting prepayment under several sales contracts.

Investing Activities

Net cash used in investing activities in 2010 was $51.8 million, as compared to $3.1 million and $88.2 million in 2009 and 2008, respectively. Net cash used in investing activities in 2010 was primarily attributable to our acquisition of SST and NRE in the aggregate amount of $46.0 million, our purchase of property, plant and equipment in the amount of $14.6 million in connection with the expansion of our solar cell manufacturing lines, partly offset by cash of $16.0 million assumed upon the acquisition of SST and NRE. Net cash used in investing activities in 2009 was primarily attributable to our purchases of property, plant and equipment in the amount of $9.9 million, partly offset by a decrease in restricted cash of $6.7 million in connection with the release of certain promissory note facilities. Net cash used in investing activities in 2008 was primarily attributable to our purchases of property, plant and equipment in the amount of $44.1 million in connection with the expansion of our solar cell manufacturing lines, as well as an increase in restricted cash of $38.9 million in connection with deposit with banks for securing letter of credit and promissory note facilities for procurement of silicon raw materials.

Financing Activities

Net cash used in financing activities was $4.6 million in 2010, primarily due to our repayment of short-term bank borrowings in the amount of $168.4 million, partly offset by proceeds from short-term bank borrowings in the amount of $133.6 million and long-term bank borrowings in the amount of $30.2 million. Net cash provided by financing activities was $3.0 million in 2009, primarily attributable to proceeds from short-term borrowings in the amount of $131.0 million, partly offset by repayment of bank borrowing in the amount of $125.9 million. Net cash provided by financing activities was $15.9 million in 2008, primarily attributable to proceeds from short-term borrowings in the amount of $142.5 million and proceeds from our issuance of convertible senior notes in the amount of $54.5 million, partly offset by repayment of bank borrowing in the amount of $175.1 million.

Historically, we have relied on our current cash, cash equivalents, short-term borrowings, proceeds from our convertible senior notes offering in July 2008 and anticipated cash flow from operations to meet our anticipated cash needs. We may, however, require additional cash as we expand our businesses. In addition, future acquisitions, investments, market changes or other developments may also require additional financing. If our existing cash is insufficient to meet our requirements, we may seek to sell additional equity securities, debt securities or borrow from banks. However, any future financial downturn may significantly restrict our ability to obtain financing in the capital markets or from financial institutions. Furthermore, we cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. The sale of additional equity securities, including convertible debt securities, would dilute our earnings per share. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating and financial covenants that restrict our operations and our ability to pay dividends to our shareholders.

66

Capital Expenditures

We incurred capital expenditures of $49.3 million, $9.9 million and $60.7 million in 2008, 2009 and 2010, respectively. Our capital expenditures have been used primarily to build our plant, purchase equipment for our solar cell manufacturing lines, and acquire module business in 2010. We estimate that our capital expenditures will be approximately $120 million to $200 million in 2011, and will be used primarily to expand our solar cell and solar module manufacturing lines.

C.Research and Development

Our senior management team heads our research and development efforts and sets strategic directions for the advancement of our products and manufacturing processes. Dr. Jianhua Zhao, our vice chairman and chief technology officer, and Dr. Aihua Wang, our vice president are all experienced solar power researchers. Under their guidance, our research and development plans include the following areas:

• Development of the manufacturing process for new solar cell structures. We focus our research and development efforts on the process technology of new type of solar cells. Based on Dr. Zhao and Dr. Wang’s previous experience working with high efficiency solar cells, including developing what were the most efficient crystalline silicon solar cells in the world, we have successfully conducted research and a large number of experiments on solving the technical problems associated with manufacturing new types of solar cells and we are in the process of developing Quasar cells.

• Increase our solar cell manufacturing efficiency and reduce the manufacturing costs. In 2010, our research team has made a concerted effort to improve the performance of our standard HP solar cells. We also made efforts in continuously optimizing the processing parameters and conditions for each manufacturing step to streamline our manufacturing process and reduce the manufacturing costs. We are also working collaboratively with metallic paste manufacturers to reduce the paste used for our manufacturing without affecting solar cell performance. Hence, our wafer-cell non-silicon costs has been reduced to a new low level of $0.20 per watt in the fourth quarter of 2010.

We believe that the continual improvement of our technology is vital to maintaining our long-term competitiveness. Therefore, we have established our own solar power research center and have installed an experimental manufacturing line dedicated to our research and development.

To further leverage our internal advanced research and development capability, we have established cooperative relationships with several universities and institutions in China, including Nanjing University, Southeast University and Hebei University of Technology, each a leading science and engineering university in China. We have also entered into cooperation agreement with CEEG (Nanjing) Semiconductor Co., Ltd., an entity controlled by our chairman, and Nanjing University of Aeronautics and Astronautics, one of the leading science and engineering universities in China, to jointly develop solar wafer cutting and texture technology. Besides, we have been collaborating with a number of solar cell equipment suppliers and material suppliers to test their new products, with the purpose to improve the performance of solar cells. In addition, we have also entered into cooperation agreement with Intelume Laser Systems (Shenzhen) Co.,Ltd., a China based laser system development Company, to jointly develop solar cells laser edge isolation equipment. We believe our collaborative efforts with these institutions have kept us apprised of the latest industry trends and developments, helped implement our own innovation initiatives and will continue to contribute to our technological advancement.

In addition, several government authorities in China, including, Ministry of Finance and Jiangsu Science and Technology Department, have provided us or committed to provide us with grants for our research in solar power technologies. Jiangsu Science and Technology Department also recognized our research and development capability by establishing the photovoltaic engineering technology research center in our company, which has passed the acceptance of Jiangsu Science and Technology Department in August 2009. We have invited solar power experts from external research institutes to form the expert commission for such research center.

Our gross expenditures on research and development were $1.9 million, $4.4 million and $3.3 million in 2008, 2009 and 2010, respectively.

D.Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events since January 1, 2010 that are reasonably likely to have a material effect on our net revenues, income, profitability, liquidity or capital resources, or that caused the disclosed financial information to be not necessarily indicative of future operating results or financial conditions.

E.Off-balance Sheet Commitments and Arrangements

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of third parties. We have not entered into any derivative contracts that are indexed to our shares and classified as shareholder’s equity, or that are not reflected in our consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that provides financing, liquidity, market risk or credit support to us or that engages in leasing, hedging or research and development services with us.

F.Contractual Obligations and Commercial Commitments

We may terminate the employment for cause, at any time, without remuneration, for certain acts of the employee, including but not limited to a conviction or plea of guilty to a felony, willful dishonesty to us and willful and continued failure to perform substantially all his agreed-to duties after a reasonable opportunity to cure the failure.

Share Incentive Plan

In October 2006, our board of directors adopted a share incentive plan, or the First Plan, later amended in April 2007 and May 2009, respectively, to link the personal interests of our board members, employees and consultants to those of our shareholders by providing them with an incentive to generate superior returns for our shareholders, as well as to provide us with the flexibility to motivate, attract and retain the services of these individuals upon whose judgment, interest and special effort the successful conduct of our operations is dependent. The First Plan provides for the grant of options, referred to as “awards,” and we have reserved 2,500,000 shares for issuance under the First Plan. We adopted a second share incentive plan, or the Second Plan, after obtaining the approval by shareholders in February 2008. We have reserved 4,190,748 shares for issuance under the Second Plan. As of December 31, 2010, our board of directors has granted certain of our officers, employees and consultants an aggregate of 1,336,794 options and 2,996,896 restricted shares, excluding options and restricted shares forfeited pursuant to the above plans.

Administration.  Our share incentive plans are administered by our compensation committee or, in its absence, by our board of directors. Our compensation committee will determine the provisions, terms and conditions of our awards.

Awards.  Awards granted are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award. Our First Plan only provides for awards in the form of options. Options provide for the right to purchase our ordinary shares at a specified price, and usually will become exercisable in installments after the grant date. The option exercise price may be paid in cash, by check, by our ordinary shares which have been held by the option holder for such time as may be required to avoid adverse accounting treatment, by other property with value equal to the exercise price, through a broker assisted cash-less exercise or by such other methods as our compensation committee or board of directors may approve from time to time.

The following paragraphs briefly describe the principal features of the various awards that may be granted under the Second Plan.

• Options.  Options provide for the right to purchase our ordinary shares at a price and period determined by our compensation committee in one or more installments after the grant date.

• Restricted Shares.  A restricted share award is the grant of our ordinary shares determined by our compensation committee. A restricted share is nontransferable, unless otherwise determined by our compensation committee at the time of award, and may be repurchased by us upon termination of employment or service during a restricted period. Our compensation committee shall also determine in the award agreement whether the participant will be entitled to vote the restricted shares or receive dividends on such shares.

• Restricted Share Units.  Restricted share units represent the right to receive our ordinary shares at a specified date in the future, subject to forfeiture of such right. If the restricted share unit has not been forfeited, then on the date specified in the award agreement, we shall deliver to the holder unrestricted ordinary shares which will be freely transferable.

Termination of Plan.  Unless terminated earlier, our First Plan and Second Plan will expire in 2016 and 2018, respectively. Our board of directors has the authority to amend or terminate our share incentive plans subject to shareholder approval to the extent necessary to comply with applicable law. However, no such action may impair the rights of any recipient of the awards unless agreed by the recipient and the share incentive plan administrator.

73

The following table summarizes, as of December 31, 2010, the outstanding options granted under our plans to several of our directors and executive officers and to other individuals.

A substantial portion of options vest over a four-year period beginning in October 2006, April 2007, January 2008, February 2008, June 2008 or January 2009. Other options vest on the first anniversary of the grant date. All restricted shares granted under our plans have either been vested or forfeited.

C.Board Practices

Board of Directors

Our board of directors currently has nine directors, all designated by the holders of our ordinary shares. As of the date of this annual report, a majority of our directors meet the “independence” definition under The Nasdaq Stock Market Marketplace Rules, or the Nasdaq Rules.

Under our amended and restated articles of association, which became effective in May 2007, our board of directors consists of at least two directors. Our directors are elected by the holders of our ordinary shares.

A director is not required to hold any shares in the company by way of qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is materially interested. A director may exercise all the powers of the company to borrow money, mortgage its undertakings, property and uncalled capital, and issue debentures or other securities whenever money is borrowed or pledged as security for any obligation of the company or of any third party. Upon the completion of our initial public offering in May 2007, we established three committees under the board of directors: the audit committee, the compensation committee and the nominating committee. We have adopted a charter for each committee.

Committees of the Board of Directors

We have established three committees under the board of directors: the audit committee, the compensation committee and the corporate governance and nominating committee. We have adopted a charter for each of the three committees. Each committee’s members and functions are described below.

Audit Committee.  Our audit committee consists of Ms. Merry Tang, Mr. Steve Morgan and Ms. Jian Li and is chaired by Ms. Merry Tang. Ms. Tang, Mr. Morgan and Ms. Li satisfy the independence requirements of Rule 10A-3 under the Exchange Act, as amended, and Rule 5605 of the Nasdaq Rules.

Corporate Governance and Nominating Committee.  Our corporate governance and nominating committee consists of Mr. Wenze Wang, Ms. Jian Li and Mr. Xiaoqian Zhou. Mr. Wang, Ms. Li and Mr. Zhou satisfy the independence requirements of Rule 5605 of the Nasdaq Rules.

Duties of Directors

Under Cayman Islands law, our directors have fiduciary duties to act honestly in good faith with a view to our best interests. Our directors also have a duty to exercise the skill they actually possess with the care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our amended and restate memorandum and articles of association. A shareholder has the right to seek damages if a duty owed by our directors is breached.

Terms of Directors and Officers

Our shareholders have designated our directors into three classes, namely Class A directors, Class B directors and Class C directors, who shall retire from office and be eligible for re-election at the first, second and third annual general meeting after our initial public offering, respectively.

ITEM 8. FINANCIAL INFORMATION

A.Consolidated Statements and Other Financial Information

We have appended consolidated financial statements filed as part of this annual report.

Legal Proceedings

We are a named defendant in three purported class actions currently pending in the United States District Court for the Southern District of New York — Brown v. China Sunergy Co., Ltd. et al., Case No. 07-CV-07895 (DAB), Sheshtawy v. China Sunergy Co., Ltd. et al., Case No. 07-CV-08656 (DAB), and Giombetti v. China Sunergy Co., Ltd. et al., Case No. 07-CV-09689 (DAB). On September 29, 2008, the District Court appointed a lead plaintiff and consolidated the three cases. The lead plaintiff filed a consolidated amended complaint on December 8, 2008.

The consolidated amended complaint purports to state class action claims against us in connection with our initial public offering and seeks unspecified damages. Specifically, the lead plaintiff alleges that we made false and misleading statements in our initial public offering registration statement and prospectus regarding, among other things, the procurement of polysilicon.

Several of our directors and officers, along with the investment banks that underwrote our initial public offering, are also named defendants in the cases. On January 26, 2009, the defendants filed a motion to dismiss the consolidated amended complaint. Briefing on the motion was completed on May 1, 2009. Defendants’ motion remained outstanding when, on July 14, 2009, the parties reached an agreement in principle to settle the dispute in its entirety with an amount of $1.1 million. The parties are currently awaiting the hearing for final approval of the settlement, set by the Court for May 12, 2011.

In September 2009, we filed a petition with the Salten District Court seeking injunction with regard to a $50 million bank guarantee, which is a security for our payment obligation under a long term supply contract entered into between REC SiTech AS, a Norwegian wafer supplier, and us in June 2008. The contract stipulates that REC SiTech AS will supply us monocrystalline 156-millimeter wafers for a seven year period between 2009 and 2015. Without obtaining our written consent as the contract requires, REC SiTech AS merged into REC Wafer Norway AS upon its dissolution on January 1, 2009. Subsequently, the bank guarantee was not renewed. REC Wafer Norway AS claimed that the non-renewal of the bank guarantee was a breach of contract which according to the supply contract is the basis for the drawdown of the bank guarantee, and it sought to draw on the bank guarantee.

The Salten District Court initially granted us the injunction prohibiting REC Wafer Norway AS from drawing on the bank guarantee but later rejected our request for an extension of the injunction upon a hearing held in January 2010. We subsequently appealed to the Court of Appeal in Norway, which denied our injunction request on April 16, 2010, and we then filed a further appeal to the supreme court of Norway. The Court of Appeal in Norway granted the injunction China Sunergy petitioned and ordered that Nordea Bank Norge ASA is prohibited from making payment and REC Wafer is prohibited from receiving payment from the US$50 million bank guarantees issued by Nordea Bank Norge ASA to REC Sitech AS. The injunction will remain in force until the Court of Appeal makes a ruling on the main dispute.

Meanwhile, the court proceeding in Norway regarding the main dispute is still ongoing. We have also served a writ claiming that REC Wafer Norway AS is not a party to the contract entered into between Sunergy Nanjing and the currently dissolved REC SiTech AS and thus not in the position to benefit from the bank guarantee. The Salten District Court in Norway has, after an oral hearing, ruled on July 5, 2010 in favor of REC Wafer and denied the claim from China Sunergy. Based on the ruling from the Supreme Court, China Sunergy has appealed the ruling from the district court. The Court of Appeal hearing, originally scheduled for March 2011, will now be held in June 2011.

We have separately filed a lawsuit against REC Wafer Norway AS with the People’s High Court of Jiangsu Province, China. The court in China has issued an injunction to the related banks to forbid these banks from making payments related to the bank guarantee. In April 2010, the People’s High Court of Jiangsu Province rejected REC Wafer Norway AS’s dissent of jurisdiction after an oral hearing.In a ruling made by

80

the Supreme Court of the People’s Republic of China on November 5, 2010, the Court denied the appeal filed by REC Wafer and made the final and binding decision that the Jiangsu Higher Court shall have Jurisdiction over the case.

Other than as described above, we are currently not a party to any material legal or administrative proceedings, and we are not aware of threatened material legal or administrative proceedings against us. We may from time to time become a party to various legal or administrative proceedings arising in the ordinary course of our business.

Dividend Policy

We have never declared or paid any dividends, nor do we have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

We are a holding company incorporated in the Cayman Islands. We rely on dividends paid by our direct and indirect subsidiaries, Sunergy BVI, Sunergy Hong Kong and Sunergy Nanjing, for our cash needs, including the payment of dividends to the holders of our ADSs and debt service on any debt we may incur through our Cayman holding company. The payment of dividends by entities organized in China is subject to limitations. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with PRC accounting standards and regulations. Sunergy Nanjing is also required to set aside at least 10% of its after-tax profit based on PRC accounting standards each year to its general reserves until the cumulative amount of such reserves reaches 50% of its registered capital. These reserves are not distributable as cash dividends. Sunergy Nanjing is also required to allocate a portion of its after-tax profits, as determined by its board of directors, to its staff welfare and bonus funds, which may not be distributed to equity owners. In addition, if Sunergy Nanjing or Sunergy BVI incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

Our board of directors has complete discretion on whether to pay dividends, subject to the approval of our shareholders. Even if our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. Any dividend we declare will be paid to the holders of ADSs, subject to the terms of the deposit agreement, to the same extent as holders of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable under. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B.Significant Changes

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited consolidated financial statements included in this annual report.

Our shareholders adopted our amended and restated memorandum and articles of association by a special resolution on April 24, 2007.

Board of Directors

See “Item 6.C. Board Practices — Board of Directors”

Ordinary Shares

General.  All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their shares.

Dividends.  The holders of our ordinary shares are entitled to such dividends as may be declared by our shareholders or board of directors subject to the Companies Law.

Voting Rights.  Each ordinary share is entitled to one vote on all matters upon which the ordinary shares are entitled to vote. Voting at any meeting of shareholders is by show of hands unless a poll is demanded or required by the rules of the designated stock exchange as described in our amended and restate articles of association. A poll may be demanded by (a) the chairman of the meeting, (b) at least three shareholders present in person or, in the case of a shareholder being a corporation, by its duly authorized representative or by proxy for the time being entitled to vote at the meeting, (c) any shareholder or shareholders present in person or, in the case of a shareholder being a corporation, by its duly authorized representative or by proxy and representing not less than one-tenth of the total voting rights of all the shareholders having the right to vote at the meeting, (d) a shareholder or shareholders present in person or, in the case of a shareholder being a corporation, by its duly authorized representative or by proxy and holding not less than one-tenth of the issued share capital of our voting shares or (e) if required by the rules of the designated stock exchange, by any director or directors who, individually or collectively, hold proxies in respect of shares representing 5% or more of the total voting rights at such meeting.

A quorum required for a meeting of shareholders consists of at least two shareholders present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative representing not less than one-third of the total issued voting shares. Shareholders’ meetings are held annually and may be convened by our board of directors on its own initiative. Advance notice of at least ten clear days is required for the convening of our annual general meeting and other shareholders’ meetings.

An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the ordinary shares. A special resolution is required for important matters such as a change of name or an amendment to our memorandum

83

or articles of association. Holders of the ordinary shares may effect certain changes by ordinary resolution, including alter the amount of our authorized share capital, consolidate and divide all or any of our share capital into shares of larger amount than our existing share capital, and cancel any unissued shares.

Transfer of Shares.  Subject to the restrictions of our amended and restated articles of association, as applicable, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or a form prescribed by the designated stock exchange or any other form approved by our board.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien or shares issued under any share incentive scheme for employees upon when a restriction on transfer imposed thereby still subsists. Our directors may also decline to register any transfer of any ordinary share unless (a) the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer; (b) the instrument of transfer is in respect of only one class of ordinary shares; (c) the instrument of transfer is properly stamped, if required; (d) in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; or (e) a fee of such maximum sum as the Nasdaq Global Market may determine to be payable, or such lesser sum as our board of directors may from time to time require, is paid to us in respect thereof.

If our directors refuse to register a transfer they shall, within two months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal. The registration of transfers may, on prior notice being given by advertisement in one or more newspapers or by electronic means, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year.

Liquidation.  On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of the ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on Shares and Forfeiture of Shares.  Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to the specified time and place of payment. The shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of Shares.  Subject to the provisions of the Companies Law, the rules of the designated stock exchange, our amended and restated memorandum and articles of association and to any special rights conferred on the holders of any shares or class of shares, we may issue shares on terms that they are subject to redemption at our option or at the option of the holders, on such terms and in such manner as may be determined by our board of directors.

Variations of Rights of Shares.  All or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Law and our amended and restated memorandum and articles of association, be varied with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class.

Inspection of Register of Members.  Pursuant to our amended and restated articles of association, our register of members and branch register of members shall be open for inspection by shareholders for such times and on such days as our board of directors shall determine, without charge, or by any other person upon a maximum payment of $2.50 or such other sum specified by the board, at the registered office or such other place at which the register is kept in accordance with the Companies Law or, upon a maximum payment of $1.00 or such other sum specified by the board, at our registration office, unless the register is closed in accordance with our amended and restated articles of association.

However, we will make this annual report, which contains our audited financial statements, available to shareholders and ADS holders. See “Item 10.H. Documents on Display.”

C.Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those described in Item 4, “Information on the Company” or elsewhere in this annual report on Form 20-F.

D.Exchange Controls

China’s government imposes control over the convertibility of RMB into foreign currencies. The conversion of RMB into foreign currencies, including U.S. dollars, has been based on rates announced by the People’s Bank of China. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy has resulted in an approximately 20.9% appreciation of the RMB against the U.S. dollar between July 21, 2005 and March 31, 2011. While the international reaction to the RMB revaluation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency policy, which could result in a further and more significant appreciation of the RMB against the U.S. dollar.

Pursuant to the Foreign Exchange Administration Regulations issued by the State Council on January 29, 1996, and effective as of April 1, 1996 (and amended on January 14, 1997 and August 5, 2008, respectively) and the Administration Rules of the Settlement, Sale and Payment of Foreign Exchange which came into effect on July 1, 1996, or the Rules, conversion of RMB into foreign exchange by foreign investment enterprises for current account items, including the distribution of dividends and profits to foreign investors of joint ventures, is permissible. Foreign investment enterprises are permitted to remit foreign exchange from their foreign exchange bank account in China on the basis of, inter alia, the terms of the relevant joint venture contracts and the board resolutions declaring the distribution of the dividend and payment of profits. The State Council amended the Foreign Exchange Administration Rules on January 14, 1997 and August 5, 2008, respectively, providing that, among other things, an important provision, as Article 5 provides that the State shall not impose restrictions on recurring international current account payments and transfers. Renminbi can be freely converted into foreign currencies for international payment under capital accounts unless Chinese laws and regulations require obtaining prior approval from SAFE. However, for the international income under capital accounts, the conversion of foreign currencies into Renminbi is still subject to the prior approval of SAFE.

Under the Rules, foreign investment enterprises are required to open and maintain separate foreign exchange accounts for capital account items (but not for other items). In addition, foreign investment enterprises may only buy, sell and/or remit foreign currencies at those banks authorized to conduct foreign exchange business upon the production of valid commercial documents and, in the case of certain capital account item transactions, document approval from SAFE.

Currently, foreign investment enterprises are required to apply to SAFE for “foreign exchange registration certificates for foreign investment enterprises” (which are granted to foreign investment enterprises, upon fulfilling specified conditions and which are subject to review and renewal by SAFE on an annual basis). With such foreign exchange registration certificates and required underlying transaction documents, or with approval documents from the SAFE if the transactions are under capital account (which are obtained on a transaction-by-transaction basis), foreign-invested enterprises may enter into foreign exchange transactions at banks authorized to conduct foreign exchange business to obtain foreign exchange for their needs.

85

E.Taxation

The following summary of the material Cayman Islands, PRC and United States federal income tax consequences of an investment in our ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report on Form 20-F, all of which are subject to change. This summary does not deal with all possible tax consequences relating to an investment in our ADSs or ordinary shares, such as the tax consequences under state, local, and other tax laws not addressed herein.

Cayman Islands Taxation

The Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties. There are no exchange control regulations or currency restrictions in the Cayman Islands.

We have received an undertaking from the Governor in Cabinet of the Cayman Islands that, in accordance with section 6 of the Tax Concessions Law (1999 Revision) of the Cayman Islands, for a period of 20 years from August 22, 2006, no law which is enacted thereafter in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to us or our operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable (i) on or in respect of the shares, debentures or other obligations of us or (ii) by way of the withholding in whole or in part of a payment of dividend or other distribution of income or capital by us to its members or a payment of principal or interest or other sums due under a debenture or other obligation of us.

People’s Republic of China Taxation

Pursuant to the New EIT Law and the New EIT Law Implementing Rules, both of which became effective on January 1, 2008, dividends generated after January 1, 2008 and payable by a foreign-invested enterprise to its foreign investors will be subject to a 10% withholding tax if the foreign investors are considered as non-PRC resident enterprises without any establishment or place of business within China or if the dividends payable have no connection with the establishment or place of business of the foreign investors within China, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced withholding arrangement. The Cayman Islands, where we are incorporated, does not have such a tax treaty with China. Sunergy Hong Kong, our wholly owned subsidiary and the direct holder of 100% equity interest in Sunergy Nanjing, is incorporated in Hong Kong. According to the Mainland and Hong Kong Special Administrative Region Arrangement on Avoiding Double Taxation or Evasion of Taxation on Income agreed between China and Hong Kong, dividends paid by a foreign-invested enterprise in China to its direct holding company in Hong Kong will be subject to withholding tax at a rate of no more than 5% (if the foreign investor owns directly at least 25% of the shares of the foreign-invested enterprise). If Sunergy Hong Kong is regarded as a non-PRC resident enterprise, and therefore would be subject to a 5% withholding tax for any dividends payable to it from Sunergy Nanjing, the amount of funds available to us to meet our cash requirements, including the payment of dividends to our shareholders and debt service on any debt we may incur through our Cayman holding company, could be materially reduced.

The New EIT Law and the New EIT Law Implementation Rules provides that enterprises established under the laws of foreign countries or regions whose “de facto management bodies” are located within the PRC are considered PRC resident enterprises and will be subject to the PRC Enterprise Income Tax at the rate of 25% on their worldwide income. Under the Implementation Rules of the New EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over manufacturing and business operations, personnel, accounting, properties, etc. of an enterprise. It is still unclear whether we will be considered a PRC resident enterprise under the New EIT Law.

Under the New EIT Law and the New EIT Law Implementation Rules, if we and Sunergy Hong Kong were regarded as PRC resident enterprises, the dividends payable to us from Sunergy Nanjing would be exempt from the PRC enterprise income tax. If Sunergy Hong Kong is regarded as a non-PRC resident

86

enterprise and the beneficial owner of the dividend, and therefore would be subject to a 5% withholding tax for any dividends payable to it from Sunergy Nanjing, the amount of funds available to us to meet our cash requirements, including the payment of dividends to our shareholders and debt service on any debt we may incur through our Cayman holding company, could be materially reduced.

In addition, if we are regarded as a PRC resident enterprise under the New EIT Law, any dividends to be distributed by us to our non-PRC shareholders or holders of ADSs will be subject to a withholding tax. Unless there are further rules announced by the Chinese tax authorities, we may be required under the New EIT Law to withhold PRC income tax on our dividends payable to our non-PRC shareholders or holders of ADSs, or any gain realized by our non-PRC shareholders or holders of ADSs from transfer of the shares or ADSs.

United States Federal Income Taxation

The following discussion describes the material U.S. federal income tax consequences to U.S. Holders (as defined below) under current law of an investment in our ADSs or ordinary shares. This discussion applies only to U.S. Holders that hold the ADSs or ordinary shares as capital assets (generally, property held for investment) and that have the U.S. dollar as their functional currency. This discussion is based on the tax laws of the United States as in effect on the date of this annual report and on U.S. Treasury regulations in effect or, in some cases, proposed as of the date of this annual report, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax consequences described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

• banks and other financial institutions;

• insurance companies;

• broker-dealers;

• traders that elect to use a mark-to-market method of accounting;

• tax-exempt entities;

• persons liable for alternative minimum tax;

• U.S. expatriates;

• regulated investment companies or real estate investment trusts;

• persons holding an ADS or ordinary share as part of a straddle, hedging, conversion or integrated transaction;

• persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee stock options or otherwise as compensation;

• persons that actually or constructively own 10% or more of the total combined voting power of all classes of our voting stock; or

• partnerships or other pass-through entities, or persons holding ADSs or ordinary shares through such entities.

INVESTORS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR ADSs OR ORDINARY SHARES.

87

The discussion below of the U.S. federal income tax consequences to “U.S. Holders” will apply to you if you are a beneficial owner of our ADSs or ordinary shares and you are, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) organized under the laws of the United States, any state thereof or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust that (1) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons for all substantial decisions or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If you are a partner in a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) that holds our ADSs or ordinary shares, your tax treatment will generally depend on your status and the activities of the partnership.

The discussion below assumes the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement have been and will be complied with in accordance with their terms. If you beneficially own our ADSs, you should be treated as the beneficial owner of the underlying ordinary shares represented by those ADSs for U.S. federal income tax purposes.

The U.S. Treasury has expressed concerns that U.S. holders of ADSs may be claiming foreign tax credits in situations where an intermediary in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS has taken actions inconsistent with the ownership of the underlying security by the person claiming the credit. Such actions (for example, a pre-release of an ADS by a depositary) may also be inconsistent with the claiming of the reduced rate of tax applicable to dividends received by certain non-corporate U.S. holders of ADSs, including individual U.S. holders (discussed below). Accordingly, the availability of foreign tax credits or the reduced tax rate for dividends received by certain non-corporate U.S. Holders, including individual U.S. Holders, could be affected by actions taken by the U.S. Treasury or the depositary.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of any distributions we make to you with respect to our ADSs or ordinary shares (including the amount of any taxes withheld there from) will generally be included in your gross income as dividend income on the date of actual or constructive receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, but only to the extent the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). To the extent the amount of the distribution exceeds our current and accumulated earnings and profits (as determined under U.S. federal income tax principles), such excess amount will be treated first as a tax-free return of your tax basis in your ADSs or ordinary shares, and then, to the extent such excess amount exceeds your tax basis, as capital gain. We currently do not, and we do not intend to, calculate our earnings and profits under U.S. federal income tax principles. Therefore, a U.S. Holder should expect a distribution will generally be reported as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above. Any dividends we pay will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to certain non-corporate U.S. Holders, including individual U.S. Holders, for taxable years beginning before January 1, 2013, dividends will be “qualified dividend income” that is taxed at the lower applicable capital gains rate, provided certain conditions are satisfied, including (1) our ADSs or ordinary shares are readily tradable on an established securities market in the United States, or we are eligible for the benefits of a qualifying income tax treaty with the United States that includes an exchange of information program, (2) we are neither a passive foreign investment company nor treated as such with respect to you for our taxable year in which the dividend is paid and the preceding taxable year, and (3) certain holding period requirements are met. U.S. Treasury guidance indicates that common or ordinary shares, or ADSs representing such shares, are considered for the purpose of clause (1) above to be readily tradable on an established

88

securities market in the United States if they are listed on the Nasdaq Global Market, as are our ADSs (but not our ordinary shares). There can be no assurance the ADSs will be considered readily tradable on an established securities market in later years. If we are deemed to be a “resident enterprise” under PRC tax law (see Item 10, “Additional Information — Taxation — People’s Republic of China Taxation”), we may be eligible for the benefits of the income tax treaty between the United States and the PRC. You should consult your tax advisors regarding the availability of the lower capital gains rate applicable to qualified dividend income for any dividends paid with respect to the ADSs or ordinary shares and any possible change in law relating to the availability of such lower rate for dividends paid by us.

Dividends will constitute foreign source income for foreign tax credit limitation purposes. If the dividends are qualified dividend income (discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will generally be limited to the gross amount of the dividend, multiplied by the reduced tax rate applicable to qualified dividend income and divided by the highest tax rate normally applicable to dividends. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, any dividends distributed by us with respect to our ADSs or ordinary shares will be “passive category income” or, in the case of certain U.S. Holders, “general category income.” In addition, if PRC withholding taxes apply to dividends paid to you with respect to the ADSs or ordinary shares (see Item 10, “Additional Information — Taxation — People’s Republic of China Taxation”), subject to certain conditions and limitations, such PRC withholding taxes may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. The rules relating to the determination of the foreign tax credit are complex, and you should consult your tax advisors regarding the availability of a foreign tax credit in your particular circumstances.

Taxation of Disposition of the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, you will recognize taxable gain or loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference between the amount realized (in U.S. dollars) for the ADS or ordinary share and your tax basis (in U.S. dollars) in the ADS or ordinary share. The gain or loss will be capital gain or loss. If you are a non-corporate U.S. Holder, including an individual U.S. Holder, who has held the ADS or ordinary share for more than one year, you will be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations.

Any gain or loss you recognize on a disposition of our ADSs or ordinary shares will generally be treated as U.S. source income or loss for foreign tax credit limitation purposes. However, if we are deemed to be a “resident enterprise” under PRC tax law and PRC tax were to be imposed on any gain from the disposition of the ADSs or ordinary shares (see Item 10, “Additional Information — Taxation — People’s Republic of China Taxation”), a U.S. Holder that is eligible for the benefits of the treaty may elect to treat such gain as PRC source income. You should consult your tax advisors regarding the proper treatment of gain or loss in your particular circumstances.

Passive Foreign Investment Company

Based on the market price of our ADSs, the value of our assets, and the composition of our income and assets, although we do not believe we were a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for our taxable year ended December 31, 2010, we cannot assure you we were not a PFIC for such year. A non-U.S. corporation will be a PFIC for any taxable year if either:

• at least 75% of its gross income for such year is passive income; or

• at least 50% of the value of its assets (based on an average of the quarterly values of the assets) during such year is attributable to assets that produce passive income or are held for the production of passive income (the “asset test”).

For this purpose, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, at least 25% (by value) of the stock.

89

We must make a separate determination after the close of each taxable year as to whether we were a PFIC for that year. The composition of our income and assets will be affected by how, and how quickly, we use the cash we generate from our operations and raise in any offering. Because the value of our assets for purposes of the asset test will generally be determined by reference to the market price of our ADSs or ordinary shares, fluctuations in the market price of the ADSs or ordinary shares may cause us to become a PFIC. Although we do not believe we were a PFIC for our taxable year ended December 31, 2010, because of the depressed market price of the ADSs and our retention of a significant amount of cash during such year, there is a significant risk we could be treated as a PFIC for such year. Accordingly, we cannot assure you we were not a PFIC for such year.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, we will generally continue to be treated as a PFIC with respect to you for all succeeding years during which you hold the ADSs or ordinary shares, unless we cease to be a PFIC and you make a “deemed sale” election with respect to the ADSs or ordinary shares, as applicable. If such election is made, you will be deemed to have sold the ADSs or ordinary shares you hold at their fair market value and any gain from such deemed sale would be subject to the rules described in the following two paragraphs. After the deemed sale election, your ADSs or ordinary shares with respect to which such election was made will not be treated as shares in a PFIC unless we subsequently become a PFIC.

For each taxable year we are treated as a PFIC with respect to you, you will be subject to special tax rules with respect to any “excess distribution” you receive and any gain you recognize from a sale or other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a “mark-to-market” election as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the ADSs or ordinary shares will be treated as an excess distribution. Under these special tax rules:

• the excess distribution or recognized gain will be allocated ratably over your holding period for the ADSs or ordinary shares,

• the amount allocated to the current taxable year, and any taxable years in your holding period prior to the first taxable year in which we were a PFIC, will be treated as ordinary income, and

• the amount allocated to each other year will be subject to the highest tax rate in effect for individuals or corporations, as applicable, for each such year, and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

The tax liability for amounts allocated to years prior to the year of disposition or excess distribution cannot be offset by any net operating losses for such years, and gains (but not losses) from a sale or other disposition of the ADSs or ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

If we are treated as a PFIC with respect to you for any taxable year, to the extent any of our subsidiaries are also PFICs or we make direct or indirect equity investments in other entities that are PFICs, you will be deemed to own shares in such lower-tier PFICs directly or indirectly owned by us in the proportion that the value of the ADSs or ordinary shares you own bears to the value of all of our ADSs and ordinary shares, and you may be subject to the rules described in the preceding two paragraphs with respect to the shares of such lower-tier PFICs that you would be deemed to own. You should consult your tax advisors regarding the application of the PFIC rules to any of our subsidiaries.

A U.S. Holder of “marketable stock” (as defined below) of a PFIC may make a mark-to-market election for such stock to elect out of the PFIC rules described above regarding excess distributions and recognized gains. If you make a mark-to-market election for our ADSs or ordinary shares, you will include in income for each year that we are a PFIC an amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares you hold as of the close of your taxable year over your adjusted basis in such ADSs or ordinary shares. You will be allowed a deduction for the excess, if any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable year. However, deductions will be allowable only to the extent of any net mark-to-market gains on the ADSs or ordinary shares included in your

90

income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as any gain from the actual sale or other disposition of the ADSs or ordinary shares, will be treated as ordinary income. Ordinary loss treatment will apply to the deductible portion of any mark-to-market loss on the ADSs or ordinary shares, as well as to any loss from the actual sale or other disposition of the ADSs or ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. If you make a valid mark-to-market election, any distributions we make would generally be subject to the tax rules discussed above under “— Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares”, except the lower capital gains rate applicable to qualified dividend income generally would not apply.

The mark-to-market election is available only for “marketable stock,” which is stock that is traded in greater thande minimis quantities on at least 15 days during each calendar quarter (“regularly traded”) on a qualified exchange or other market, as defined in applicable U.S. Treasury regulations. Our ADSs are listed on the Nasdaq Global Market, which is a qualified exchange or other market for these purposes. Consequently, if the ADSs continue to be listed on the Nasdaq Global Market and are regularly traded, and you are a holder of ADSs, we expect the mark-to-market election would be available to you if we become a PFIC. Because a mark-to-market election cannot be made for equity interests in any lower-tier PFICs that we own, a U.S. Holder may continue to be subject to the PFIC rules described above regarding excess distributions and recognized gains with respect to its indirect interest in any investments held by us that are treated as an equity interest in a PFIC for U.S. federal income tax purposes.

Alternatively, a U.S. Holder of stock of a PFIC may make a “qualified electing fund” election with respect to such corporation to elect out of the PFIC rules described above regarding excess distributions and recognized gains. A U.S. Holder that makes a valid qualified electing fund election with respect to a PFIC will generally include in income for a taxable year such holder’spro rata share of the corporation’s income for the taxable year. However, the qualified electing fund election is available only if the PFIC provides such U.S. Holder with certain tax information as required under applicable U.S. Treasury regulations. We do not intend to prepare or provide the information that would enable you to make a qualified electing fund election.

Unless otherwise provided by the U.S. Treasury, each U.S. shareholder of a PFIC is required to file an annual report containing such information as the U.S. Treasury may require. If we are or become a PFIC, you should consult your tax advisors regarding any reporting requirements that may apply to you.

You should consult your tax advisors regarding the application of the PFIC rules to your investment in our ADSs or ordinary shares.

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or other disposition of ADSs or ordinary shares may be subject to information reporting to the Internal Revenue Service and possible U.S. backup withholding at a current rate of 28%, unless the conditions of an applicable exception are satisfied. Backup withholding will not apply to a U.S. Holder that furnishes a correct taxpayer identification number and makes any other required certification on Internal Revenue Service Form W-9 or that is otherwise exempt from backup withholding. U.S. Holders that are required to establish their exempt status generally must provide such certification on Internal Revenue Service Form W-9. Certain individuals holding the ADSs or ordinary shares other than in an account at certain financial institutions may be subject to additional information reporting requirements. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information in a timely manner.

I.Subsidiary Information

For a listing of our subsidiaries, see Item 4, “Information on the Company — Organizational Structure.”

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Inflation

Since our inception, inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the consumer price index in China increased by 3.9%, 1.8%, 1.5%, 4.8% and 5.9% in 2004, 2005, 2006, 2007 and 2008, respectively, and decreased slightly by 0.7% in 2009. In 2010, the consumer price index increased by 3.3%.

Foreign Exchange Risk

A major portion of our sales are denominated in Renminbi and Euros, with the remainder in U.S. dollars. Since the acquisition of SST and NRE, a substantial portion of our costs and expenses have been denominated in U.S. dollars and Renminbi, with the remainder in Euros. Therefore, fluctuations in currency exchange rates could have a significant impact on our financial stability due to a mismatch among various foreign currency-denominated sales and costs. Fluctuations in exchange rates, particularly among the U.S. dollar, Renminbi and Euro, affect our gross and net profit margins and could result in foreign exchange and operating losses.

Our exposure to foreign exchange risk primarily relates to currency gains or losses resulting from timing differences between signing of sales contracts and settling of these contracts. As of December 31, 2010, we had a Renminbi denominated cash balance of RMB527.7 million and a U.S. dollar denominated cash balance of $2.2 million. Assuming we had converted the Renminbi denominated cash balance of RMB527.7 million as of December 31, 2010 into U.S. dollar at the exchange rate of RMB6.6227 for $1.00 as of December 31, 2010, this cash balance would have been $79.7 million. Assuming a further 1% appreciation of the U.S. dollar against the Renminbi, this cash balance would have decreased to $78.9 million as of December 31, 2010.

92

Therefore, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, any appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us.

We are also subject to foreign currency translation risk. Our financial statements are expressed in U.S. dollars but the functional currency of our operating subsidiary is Renminbi. We translate monetary assets and liabilities denominated in other currencies into Renminbi at the rates of exchange in effect at each balance sheet date. Depending on movements in foreign exchange rates, the foreign currency translation may have an adverse impact on our consolidated financial statements. We recorded these exchange gains and losses in the statements of operations. We recorded net foreign currency losses of $6.9 million, $0.5 million and $5.1 million in 2008, 2009 and 2010, respectively.

In 2010, we entered into a series of foreign currency forward contracts with certain banks to hedge our exposure to foreign currency exchange risk. As of December 31, 2010, we had foreign currency forward contracts with a total contract value of approximately EUR8.0 million and $ 4.6 million, respectively. As with all hedging instruments, there are risks associated with the use of foreign currency forward contracts. As at December 31, 2010, we recorded a gain on change in fair value of derivatives related to the forward foreign currency exchange contracts of $2.9 million, which was included in the line item “Change in fair value of derivative” in the consolidated statements of operations. While the use of such foreign currency forward contracts provides us with protection from certain fluctuations in foreign currency exchange, we potentially forgo the benefits that might result from favorable fluctuations in foreign currency exchange. In addition, any default by the counterparties to these transactions could adversely affect our financial condition and results of operations.

Counterparty Risk

Outstanding financial derivative instruments expose us to credit loss in the event of non-performance by the counterparties to the agreements. On a periodic basis, we review the credit ratings of our counterparties and adjust our exposure as deemed appropriate. The counterparty risk has been considered in the fair value measurement of derivative instruments.

Interest Rate Risk

Our exposure to interest rate risk primarily relates to interest expenses incurred by our short-term and long-term borrowings, as well as interest income generated by excess cash invested in demand deposits with original maturities of three months or less. Such interest-earning instruments carry a degree of interest rate risk. We have not used any derivative financial instruments to manage our interest rate risk exposure. As of December 31, 2010, we had total short-term bank borrowings amounting to $139.5 million and total long-term bank borrowings amounting to $30.2 million. The average interest of our short-term and long-term borrowings was 5.33% and 3.51%, respectively. Based on our bank borrowings as of December 31, 2010, a 1% increase in average interest rate of short-term and long-term loan would result in approximately a $0.1 million increase in our interest expense on an annual basis. Our future interest expense may increase due to changes in market interest rates.

The depositary has agreed to reimburse us for certain expenses we incur that are related to establishment and maintenance of the ADR program, including investor relations expenses and stock exchange application and listing fees. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of reimbursement available to us is not related to the amounts of fees the depositary collects from investors. In 2010, we received $57,500 from the depository as reimbursement relating to the ADS facility.

ITEM 15. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures within the meaning of Rules 13a-15(e) and 15d-15(e) of the Exchange Act as of the end of the period covered by this report. Based on such evaluation, our management has concluded that, as of the end of the period covered by this annual report, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the

96

preparation of consolidated financial statements in accordance with generally accepted accounting principles and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of a company’s assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that a company’s receipts and expenditures are being made only in accordance with authorizations of a company’s management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of a company’s assets that could have a material effect on the consolidated financial statements. Our management excluded from our assessment the internal control over financial reporting at SST and NRE which were acquired on November 1, 2010, and whose aggregated financial statements constitute -1.9% and 25.6% of net and total assets, respectively, 4.4% percent of revenues, and -2.1% percent of net income of the consolidated financial statement amounts as of and for the year ended December 31, 2010.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness of our internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

As required by Section 404 of the Sarbanes-Oxley Act and related rules as promulgated by the SEC, management assessed the effectiveness of our internal control over financial reporting as of December 31, 2010 using criteria established inInternal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this assessment, management concluded that the our internal control over financial reporting was effective as of December 31, 2010 based on the criteria established inInternal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our independent registered public accounting firm, Deloitte Touche Tohmatsu CPA Ltd., has audited our internal control over financial reporting included in this annual report on Form 20-F.

Attestation Report of the Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of China Sunergy Co. Ltd.

We have audited the internal control over financial reporting of China Sunergy Co., Ltd. (the “Company”) and subsidiaries (collectively referred to as the “Group”) as of December 31, 2010, based on the criteria established inInternal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at CEEG (Shanghai) Solar Science & Technology Co., Ltd. (“SST”) and CEEG (Nanjing) Renewable Energy Co., Ltd. (“NRE”) which were acquired on November 1, 2010, and whose aggregated financial statements constitute -1.9% and 25.6% of net and total assets, respectively, 4.4% of revenues, and -2.1% of net income of the consolidated financial statement amounts as of and for the year ended December 31, 2010. Accordingly, our audit did not include the internal control over financial reporting at SST and NRE. The Group’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Group’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

97

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established inInternal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and the related financial statement schedule as of and for the year ended December 31, 2010 of the Group and our report dated April 29, 2011 expressed an unqualified opinion on those financial statements and financial statement schedule.

Changes in Internal Control over Financial Reporting

During 2010, to address the significant deficiency identified by our independent registered public accounting firm in connection with the audit of our financial statements as of and for the year ended December 31, 2009,

• We implemented additional control procedures to strengthen the communications between accounting department and other relative departments prior to quarterly closing;

• We also designed and implemented controls to ensure that significant non-routine transactions were properly reviewed, analyzed and monitored by sufficient and appropriate accounting staff member on a timely basis.

In addition, with the completion of acquisition, we have started to implement the relevant controls of the newly acquired entities of SST and NRE.

ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES

The following table sets forth the aggregate fees by categories specified below in connection with certain professional services rendered by Deloitte Touche Tohmatsu CPA Ltd., our principal external auditors, for the periods indicated. We did not pay our auditors any fees other than audit fees in 2009 and 2010.

	2009		2010
Audit fees(1)	$	1,097,871	$	1,461,549
Audit-related fees(2)		—		—
Tax fees		—		—
All other fees		—		—

(1) “Audit fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered by our principal auditors for the audit of our annual financial statements.

(2) “Audit-related fees” means the aggregate fees billed in each of the fiscal years listed for assurance and related services by our principal auditors that are reasonably related to the performance of the audit or review of our financial statements and are not reported under “Audit fees.” Services comprising the fees disclosed under the category of “Audit-related fees” involve principally the issue of comfort letter, rendering of listing advice, and other audit-related services for the years ended December 31, 2009 and December 31, 2010.

We engaged Deloitte Touche Tohmatsu CPA Ltd. in 2006. Total service fees billed related to these professional services in 2009 and 2010 amounted to $1,097,871 and $1,461,549, respectively.

The policy of our audit committee is to pre-approve all audit and non-audit services provided by Deloitte Touche Tohmatsu CPA Ltd., including audit services, audit-related services, tax services and other services as described above, other than those for de minimus services which are approved by the Audit Committee prior to the completion of the audit.

ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES

We are in compliance with the Nasdaq corporate governance rules with respect to the audit committee.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS.

During the fourth quarter of 2008, we conducted open market repurchases of the convertible senior notes, and through December 31, 2008, we repurchased $6.5 million aggregate principal amount of the convertible senior notes for a total cash consideration of $2.0 million.

In June 2009, we conducted open market repurchases of $4.0 million aggregate principal amount of the convertible senior notes for a total cash consideration of $1.8 million.

ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT

Not applicable.

ITEM 16G. CORPORATE GOVERNANCE

Rule 5635(c) of the Nasdaq Rules requires a Nasdaq listed company to obtain its shareholders’ approval of stock option plans or other equity compensation arrangements, and any material amendments to such plans or arrangements. Rule 5615 of the Nasdaq Rules permits a foreign private issuer like our company to follow home country practice in certain corporate governance matters. Upon board approval in May 2009, we effected amendments to our First Plan. We believe that some of the amendments are material changes to the then existing plan. Our Cayman Islands counsel has provided a letter to Nasdaq dated May 14, 2009, confirming that under the existing Cayman Islands law, we are not required to obtain shareholders’ approval for amendments to our existing equity incentive plan. Nasdaq has acknowledged the receipt of such letter and our home country practice with respect to approval for amendments to our equity incentive plan.

99

Other than the home country practice described above, we are not aware of any significant ways in which our corporate governance practices differ from those followed by U.S. domestic companies under the Nasdaq Rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of China Sunergy Co. Ltd.

We have audited the accompanying consolidated balance sheets of China Sunergy Co., Ltd. (the “Company”) and subsidiaries (collectively referred to as the “Group”) as of December 31, 2009 and 2010, and the related consolidated statements of operations, changes in equity and comprehensive income (loss), and cash flows for each of the three years in the period ended December 31, 2010 and the related financial statement schedule included in Schedule I. These financial statements and financial statement schedule are the responsibility of the Group’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Group as of December 31, 2009 and 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

As discussed in Note 3 to the consolidated financial statements, effective January 1, 2010, with the adoption of new accounting standards, the Group changed its method of accounting for its own-share lending arrangement, and retrospectively applied the requirements to all periods presented.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Group’s internal control over financial reporting as of December 31, 2010, based on the criteria established inInternal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 29, 2011 expressed an unqualified opinion on the Company’s internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 2008, 2009 AND 2010
(In U.S. dollars, except share data and unless otherwise stated)

1. ORGANIZATION AND PRINCIPAL ACTIVITIES

China Sunergy Co., Ltd. (the “Company” or “China Sunergy Cayman”) was incorporated under the laws of the Cayman Islands on August 4, 2006. The Company and its subsidiaries (collectively referred to as the “Group”) are principally engaged in the design, development, manufacturing and marketing of solar cells and modules in the People’s Republic of China (the “PRC”) and overseas markets.

As of December 31, 2010, the Company’s subsidiaries include the following entities:

Subsidiaries' Name	Principal Activities	Date of Incorporation or acquisition	Percentage of Ownership	Place of Incorporation
China Sunergy Co., Ltd. (“China Sunergy BVI”)	Investment Holding	January 27, 2006	100%	British Virgin Islands
China Sunergy (Hong Kong) Co., Limited (“Sunergy Hong Kong”)	Investment Holding	December 7, 2007	100%	Hong Kong
China Sunergy Europe Gmbh	Marketing Service	November 27, 2007	100%	Germany
China Sunergy (Nanjing) Co., Ltd. (“Sunergy Nanjing”)	Solar cells manufacturing	August 2, 2004	100%	PRC
China Sunergy (Shanghai) Co., Ltd. (“Sunergy Shanghai”)	Solar cells manufacturing	November 1, 2007	100%	PRC

CEEG (Nanjing) Renewable Energy Co., Ltd (“NRE”)	Modules manufacturing	November 1, 2010	100%	PRC

On November 1, 2010, Sunergy Nanjing acquired all of the equity interests of SST and NRE. See Note 4 “Business acquisitions” for details.

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

(a) Basis of presentation

The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

(b) Basis of consolidation

The consolidated financial statements include the assets, liabilities, revenues and expenses of the Group. All significant intercompany transactions and balances have been eliminated on consolidation.

(c) Use of estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Group bases its estimates on historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Significant accounting estimates reflected in the consolidated financial statements include provision for uncertain tax positions and valuation allowances of deferred tax assets, contingent liability relates to outstanding legal proceedings, inventory valuation, purchase commitment, allowance on accounts receivable and supplier advances, provision of warranty costs, assumptions used in calculating fair value of embedded derivative in long-term purchase contract and foreign exchange forward

contracts, forfeiture rate of options, purchase price allocation and the useful lives for property, plant and equipment, intangible assets and impairment of intangible assets and goodwill.

(d) Cash and cash equivalents and restricted cash

Cash and cash equivalents consist of cash on hand and demand deposits, which are unrestricted as to withdrawal and use, and which have original maturities of three months or less.

Restricted cash represents bank deposits for securing letter of credit, bank promissory note and bank guarantee that are not available for use in operations.

(e) Fair value of financial instruments

Assets and liabilities that are recorded at fair value on a recurring basis reflect fair value as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) on the measurement date in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. The Group applies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows:

• Level 1 — Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

• Level 2 — Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

• Level 3 — Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group measures fair value using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and currency rates.

(f) Account receivables and allowance for doubtful accounts

Trade receivables are recognized and carried at the original transaction amount less an allowance for doubtful accounts. The Group maintains allowances for doubtful accounts for uncollectible accounts receivables. Estimated anticipated losses from doubtful accounts are based on days past due, historical collection and other factors.

(g) Inventories

Inventories are stated at the lower of cost or market value. Cost is determined using the weighted-average method.

The Group estimates excess and slow moving inventory based upon assumptions of future demands and market conditions. If actual market conditions are less favorable than projected by management, additional inventory write-downs may be required.

(In U.S. dollars, except share data and unless otherwise stated)

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

(h) Property, plant and equipment, net

Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on a straight-line basis over the following estimated useful lives:

Buildings	20 years
Machinery	10 years
Furniture, fixtures and equipment	5 years
Motor vehicles	5 years
Leasehold improvements	Over the shorter of the lease term or their estimated useful lives

Costs incurred in constructing new facilities, including progress payments and other costs related to construction, are capitalized and transferred to property, plant and equipment on completion, at which time depreciation commences. Interest cost incurred and capitalized in respect of construction of new facilities amounted to $2,492,328, $1,074,430 and $115,748 for the years ended December 31, 2008, 2009 and 2010, respectively.

(i) Prepaid land use rights

Prepaid land use rights are recorded at cost and are charged to the income statement ratably over 50 years, according to the term of the land use right agreement.

(j) Intangible assets, net

Intangible assets consist primarily of customer relationships acquired in business combinations and are amortized on a straight line basis. Intangible assets acquired through business combinations are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion. Intangible assets are recognized and measured at fair value upon acquisition.

(k) Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the identifiable assets less liabilities acquired. Goodwill is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired. The Group completes a two-step goodwill impairment test. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. Management performs its annual goodwill impairment in November. No goodwill was impaired for the year ended December 31, 2010.

(In U.S. dollars, except share data and unless otherwise stated)

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

(l) Impairment of long-lived assets

The Group evaluates its long-lived assets and finite lived intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When these events occur, the Group measures impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group would recognize an impairment loss equal to the excess of the carrying amount over the fair value of the assets.

The Group identified certain long-lived assets that were no longer actively used due to obsolete technology or poor physical conditions as of December 31, 2009. Such assets were impaired in accordance with ASC 360, resulting in a loss of $824,676, which was recorded in general and administrative expenses in the consolidated statement of operations.

(m) Derivative financial instruments

The Group enters into certain long-term supply contracts that may contain embedded derivatives that need to be bifurcated if the terms of the contracts are neither denominated in the functional/local currency of either contracted parties nor in the currency such goods are routinely denominated in international commerce. The Group accounts for such embedded derivatives at fair value and records the change in the statement of operations.

The Group entered into certain foreign exchange forward contracts to protect against volatility of future cash flows caused by the changes in foreign exchange rates associated with sales contracts denominated in Euro or U.S. dollar. The Group recognizes all derivative instruments as either assets or liabilities at fair value in the consolidated balance sheets. The derivatives do not qualify for hedge accounting and, as a result, the changes in fair value of the derivatives are recognized in the statement of operations.

(n) Income taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net operating loss carryforwards and credits by applying enacted tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities, or the expected timing of their use when they do not relate to a specific asset or liability.

(o) Revenue recognition

Sales of solar cells and modules are recorded when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is reasonably assured. Customers do not have any general rights of return but may be allowed to exchange for goods that are not defective but may not meet certain minor specifications such as color or sizes of the products for a 30 to 45 day period. The Group has recorded the estimated replacement costs, which have been immaterial for all periods, resulting from the product exchanges in cost of revenue upon the recognition of revenue. A portion of the Group’s sales to domestic customers require the customers to prepay before delivery has occurred. Such prepayments are recorded as advances from customers in the consolidated balance sheets until delivery has occurred. A majority of the Group’s contracts with overseas customers are written such that the customer takes title and assumes the risks and rewards of ownership of the products upon shipment. Accordingly, the Group recognizes revenue upon documentary evidence of shipment, assuming all other criteria have been met.

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

(p) Buy-and-sell arrangements

In 2008 the Group had buy-and-sell arrangement with certain raw material vendors wherein the Group sells finished goods, comprised of solar cells, and acquires raw materials in the form of silicon wafers. These arrangements are with counterparties in the same line of business as the Group and are executed as a means of securing a consistent supply of silicon wafer raw materials. In 2009 and 2010, the Group enters into arrangements wherein the Group purchases raw material silicon wafers and sells polysilicon or solar cells to the same counterparties. These arrangements are for making profits from trading of polysilicon. The Group records such transactions at fair value.

Transactions under buy-and-sell arrangement are as follows:

	Years ended December 31,
	2008		2009		2010
	$		$		$
Sell:
Polysilicon		—		17,253,185		12,962,514
Solar cell		1,529,131		—		1,078,520
Purchase:
Solar wafer		1,504,018		69,823,276		62,506,786

(q) Cost of revenue

Cost of revenue includes production related material costs and indirect manufacturing costs, i.e. depreciation costs, utility costs, personnel cost etc., as well as shipping and handling costs for products sold and warranty costs.

(r) Research and development

Research and development costs are expensed when incurred.

(s) Advertising expenses

Advertising costs are expensed as incurred. The Group incurred advertising costs amounting to $495,162, $425,750 and $795,162 for the years ended December 31, 2008, 2009 and 2010, respectively.

(t) Warranty cost

Solar modules are typically sold with 25 year warranty against specified declines in the initial minimum power generation capacity at the time of sale. In addition, the Group provided warranty for solar modules against defects in materials and workmanship for a period of five years from the date of sale. The Group estimates and accrues the costs of warranties at 1% of module sales.

Due to very limited claims incurred to date, the warranty provisions for cells and modules are mainly based on an assessment of competitors’ accrual history and industry practice.

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

(u) Government grants

Government grants are recognized when received and all the conditions for their receipt have been met. Government grants are recognized as other income in the period in which the related expenditures are recorded. Capital grants for the acquisition of equipment are recorded as a liability until earned and then offset against the related capital assets.

(v) Foreign currency translation

The reporting currency of the Group is the United States dollar (“US dollar”).

The functional currency of the Company is US dollar. Monetary assets and liabilities denominated in other currencies other than the US dollar are translated into US dollar at the rates of exchange in effect at the balance sheet dates. Transactions dominated in currencies other than the US dollar during the year are converted into US dollar at the applicable rates of exchange prevailing when the transactions occur. Transaction gains and losses are recorded in the statements of operations.

The financial records of the Group’s subsidiaries are maintained in their local currencies. Assets and liabilities are translated at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenue, expenses, gains and losses are translated at the average rate for the period. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive income in the statements of equity.

(w) Comprehensive income (loss)

Comprehensive income (loss) includes all changes in equity except those resulting from investments by owners and distributions to owners and is comprised of net income (loss) and foreign currency translation adjustments.

(x) Foreign currency risk

The functional currency of the Group’s subsidiaries which operate in the PRC is Renminbi (“RMB”). The RMB is not a freely convertible currency. The PRC State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into foreign currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China foreign exchange trading system market. The Group’s aggregate amount of cash and cash equivalents and restricted cash denominated in RMB amounted to USD equivalent of $125,748,915 and $153,240,564 at December 31, 2009 and 2010, respectively.

(y) Concentration of credit risk

Financial instruments that potentially expose the Group to significant concentrations of credit risk consist principally of cash and cash equivalents, accounts receivable and advance to suppliers. The Group places its cash and cash equivalents with financial institutions with high-credit ratings and quality.

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

The Group performs ongoing credit evaluations of customers and suppliers and generally does not require collateral or other security from its customers. The Group establishes an allowance for doubtful accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers.

(z) Net income (loss) per share

Basic income (loss) per share is computed by dividing income (loss) attributable to holders of ordinary shares by the weighted-average number of ordinary shares outstanding during the year. Diluted income (loss) per ordinary share reflects the potential dilution that could occur if securities or other contracts to issue ordinary shares were exercised or converted into ordinary shares. Generally, ordinary share equivalents are excluded from the computation in loss periods as their effects would be anti-dilutive.

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

For the years ended December 31, 2008, 2009 and 2010, the Group had securities which could potentially dilute basic earnings per share in the future, but which were excluded from the computation of diluted earnings (loss) per share as their effects would have been anti-dilutive. Such outstanding securities consist of the following:

(aa) Share-based compensation

The Group recognizes the services received in exchange for awards of equity instruments based on the grant-date fair value of the award as determined by the Binomial option pricing model, net of estimated forfeitures. The estimated compensation cost is recognized using straight line method over the period the granter is required to provide services per the conditions of the award. See Note 17, “Share Based Compensation”, for further details.

(ab) Recently issued accounting pronouncements

In December 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2010-28, “When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” This ASU amends guidance for Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES  – (continued)

to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. ASU 2010-28 is effective for fiscal years and interim periods beginning after December 15, 2010, with early adoption not permitted. The Group does not expect that the adoption of ASU 2010-28 will have a material impact on its financial position, results of operations, or cash flows.

In December 2010, the FASB issued ASU 2010-29, “Disclosure of Supplementary Pro Forma Information for Business Combinations.” This ASU specifies that if a public company presents comparative financial statements, the entity should only disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period. ASU 2010-29 is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010, with early adoption permitted. The adoption of ASU 2010-29 will not impact the Group’s financial position, results of operations, or cash flows, as its requirements only pertain to financial statement footnote disclosure.

3. CHANGE OF ACCOUNTING PRINCIPLES

On January 1, 2010, the Group adopted the new accounting standard (ASC 470-20) that impacts the accounting for its own-share lending arrangement. The new accounting standard requires the share-lending arrangement entered into on an entity’s own shares in contemplation of a convertible debt offering to be measured at fair value and recognized as an issuance cost, with an offset to additional paid-in capital in the financial statements. Retrospective application is required. As a result, additional debt issuance costs at issuance of $1.9 million would be amortized over the life of the convertible notes with a credit charged to additional paid-in capital since issuance.

Adjustments related to retrospective adoption of new accounting pronouncements — certain prior year amounts in the Company’s audited consolidated financial statements have been adjusted to reflect the retrospective adoption of the new standards on share lending arrangement. The impacts on the audited Consolidated Balance Sheet as of December 31, 2009, and the audited Statements of Operations for each of the two years in the period ended December 31, 2009 are summarized below.

4. BUSINESS ACQUISITIONS

On November 1^st, 2010, Sunergy Nanjing acquired all of equity interests of CEEG (Shanghai) Solar Science & Technology Co., Ltd. (“SST”) and CEEG (Nanjing) Renewable Energy Co., Ltd. (“NRE”), both of which were related parties at the time of such transactions, from China Electric Equipment Group Co., Ltd., or CEEG, an entity controlled by Board Chairman Mr. Tingxiu Lu, and Sundex Holdings Limited, a company not affiliated with the Group, at a total consideration of approximate $46 million. SST and NRE integrate the research and development, production, sales and servicing of solar modules, with total annual production capacities of 480MW as of December 31 2010. The acquisitions facilitate the implementation of corporate strategy to expand into downstream solar power business, including solar module and solutions businesses.

The following table summarizes the consideration paid for SST and NRE and the amounts of the assets acquired and liabilities assumed recognized at the acquisition date, as well as the fair value of recognized intangible assets at the acquisition date:

The Group has short term credit facility of $371.7 million from various banks to facilitate its purchase of raw materials, of which $177.0 million were withdrawn with $194.7 available to use as of December 31, 2010. Those short-term credit facilities are renewable annually upon mutual agreement between the parties.

10. DERIVATIVES FINANCIAL INSTRUMENTS

During 2008, the Group entered into a long-term silicon supply contract that the purchase price of the silicon to be acquired was denominated in U.S. dollars, which is not the functional currency of either of the contracting parties. Accordingly, the contract contains an embedded foreign exchange forward contract, which is required to be bifurcated and accounted for at fair value. Subsequent changes in fair value are recorded in the consolidated statements of operations.

As of December 31, 2008, the fair value of embedded foreign currency derivatives related to the purchase contract amounted to $7,603,956 and was recorded as derivative liability. The loss arising from the embedded foreign currency derivative instruments amounted to $7,611,513 for the year ended December 31, 2008 has been recorded as “Change in fair value of derivatives” in the consolidated statements of operations.

As of December 31, 2009, the derivative liability related to this long-term supply contract was extinguished due to the termination of such supply contract on September 9, 2009 and resulted in to a gain of $7,611,132 for the year ended December 31, 2009 which has been recorded as “Change in fair value of derivatives” in the consolidated statements of operations. The fair value measurement of embedded derivative for long-term purchase contract was classified as level 3 measurement as its valuation involved significant inputs that were not observable in the market.

The Group recorded a loss of $2.3 million, a loss of $0.4 million and $2.9 million gain relating to foreign exchange forward contracts that did not qualify for hedge accounting for the years ended December 31, 2008, 2009 and 2010, respectively. As of December 31, 2008, 2009 and 2010, the Group had outstanding foreign exchange forward contracts with notional amount of $46.6 million, $8.6 million and $15.2 million, respectively, with estimated fair value of $1.5 million, $0.3 million and $0.4 million, respectively. These forward contracts are recorded in prepaid expense and other current assets on the consolidated balance sheet and the gain (loss) is recorded in changes in fair value of derivatives on the consolidated statements of operations.

11. FAIR VALUE MEASUREMENT

As of December 31, 2009 and 2010, information about inputs into the fair value measurements of the Group’s assets and liabilities that are measured at fair value on a recurring basis in periods subsequent to their initial recognition is as follows:

	Fair Value Measurements at December 31, 2009
	Total		(Level 1)	(Level 2)		(Level 3)
Assets:
Foreign exchange forward contract	$	251,208		$	251,208

Assets:
Foreign exchange forward contract	$	427,740		$	427,740
Total assets	$	427,740		$	427,740

The following is a description of the fair value techniques used for instruments measured at fair value as well as the general classification of such instruments pursuant to the valuation hierarchy described above.

Foreign exchange forward contract: Quoted prices in active markets for identical assets are not available. The term of the forward contracts held by the Group is less than one year. Main inputs for these short-term forward contracts include foreign exchange rates, which are observable and can be obtained from third party professional pricing sources. These fair value measurements are classified as level 2.

As of December 31, 2010, the carrying amounts of accounts receivable, advances to suppliers, accounts payable, notes payable, advance from customers, amount due from (to) related parties and short-term borrowings approximate their fair values due to their short-term nature.

The carrying amount of the Group’s outstanding convertible notes was US$44 million in 2009 and 2010, the estimated fair value of this debt was US$20 million and US$18.5 million as of December 31, 2009 and 2010, respectively, which was estimated using market quotes.

The fair value estimates presented above are based on pertinent information available to management as of December 31, 2009 and 2010, respectively. Although management is not aware of any factors that would significantly affect these fair value estimates, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates, and current estimates of fair value may differ significantly from the amounts presented.

12. CONVERTIBLE SENIOR NOTES

On July 1, 2008, the Company issued US$54.5 million aggregate principal amount (includes USD 4.5 million from exercise of over-allotment option in full) of Convertible Senior Notes (“Convertible Notes” or “Notes”) due June 15, 2013, with an interest rate of 4.75% per annum, payable in arrears semi-annually on June 15 and December 15, beginning December 15, 2008.

Conversion

Each $1,000 principal amount of the Notes will initially be convertible into 81.30 American Depository Shares, or ADSs, par value $.0001 per share at a conversion price of $12.3, subject to adjustment. The Notes are convertible into a number of ADSs equal to the conversion rate, at any time prior to the close of business on the third business day immediately preceding the maturity date. Securities may be converted only in denominations of USD 1,000 principal amount and integral multiples thereof.

12. CONVERTIBLE SENIOR NOTES  – (continued)

If Notes are converted in connection with a fundamental change, then the conversion rate of the Notes being converted shall be increased by an additional number of ADSs. The conversion rate, including any additional ADSs added to the conversion rate in connection with a fundamental change, will not exceed 97.56 ADSs (equal to a conversion price of USD10.25 per ADS). Such maximum conversion rate will be appropriately adjusted for anti-dilution conversion rate adjustments.

Redemption

In the event of a fundamental change, holders have the option to require the Company to repurchase the entire principal amount of this Notes, or the portion thereof (which is $1,000 or an integral multiple thereof), at the fundamental change Repurchase Price, together with accrued interest to, but excluding the repurchase date.

Upon such declaration, the principal of, and accrued and unpaid interest (including any additional amounts) on all Notes shall be due and payable immediately.

Offering expenses incurred for issuing of Convertible Notes amounted to $6.2 million, and are being amortized through interest expense over the beneficiary period from July 2008 to June 2013, using the effective interest rate method. These capitalized costs are reported as deferred assets in Convertible bond issuance cost, and $1.3 million and $1.4 million and $1.0 million was amortized for the year ended December 31, 2008 and 2009 and 2010, respectively.

Share Lending Agreement

Concurrent with this offering, 4,431,000 ADSs were borrowed by an affiliate of the initial purchaser of the notes pursuant to an ADS lending agreement, and offered in a transaction registered under the Securities Act. This is designed to facilitate short sales and/or privately negotiated derivative transactions by which investors may elect to hedge their investments in the Convertible Notes.

The Loaned Shares must be returned to the Group by the earliest of (a) the maturity date of the Notes, June 15, 2013, (b) upon the Group’s election to terminate the Share Lending Agreement at any time after the later of (i) the date on which the entire principal amount of the Notes ceases to be outstanding, and (ii) the date on which the entire principal amount of any additional convertible securities that the Group has in writing consented to permit the ADS Borrower to hedge under the Share Lending Agreement ceases to be outstanding, in each case, whether as a result of conversion, redemption, repurchase, cancellation or otherwise; and (c) the termination of the Share Lending Agreement. The Group is not required to make any payment to the underwriter of the Notes (“Underwriter”) or the ultimate holder of the Notes (“the ADS Borrower”) upon the return of the Loaned Shares.

The Underwriter has agreed to post collateral in cash, having a market value equal to at least 100% of the market value of the Loaned Shares during the term of the Share Lending Agreement. Otherwise, the Group can demand that the Underwriter transfer to the collateral agent, a deposit equal to 100% of the market value of the Loaned Shares to the Collateral Account, no later than the second following business day. The collateral agent will promptly give the Group a statement setting forth the Market Value of all Collateral upon the Group’s reasonable request and the Group has the right to audit the Market Value of all Collateral.

The collateral agent is required to deliver to the Group any interest, distributions or dividends on the date of such interest, distribution or dividends are received. The Underwriter has agreed not to vote the Loaned Shares to the extent it is the shareholder of record. An ADS Borrower has the ability to vote without restriction.

12. CONVERTIBLE SENIOR NOTES  – (continued)

A nominal lending fee of US$0.0006 per ADS was received from the ADS borrower for the use of the borrowed ADSs. The ADS Borrower will be required to return the borrowed ADSs pursuant to the ADS lending agreement by the scheduled maturity date of the notes in June 2013. The loaned ADS were accounted for as being reflected at their par value in the common stock line item of the Group’s balance sheet, with an offsetting reduction of additional paid in capital.

The Group used the proceeds from the issuance of the Convertible Notes for expansion of production capacity, for enhancement of research and development, and for general corporate purposes.

The Group has accounted for the Share Lending Agreement as the issuance of a written call option to the ADS Borrower for the fair value of the associated ADSs. The Group has recorded the call option at fair value, given the Group has no economic benefit associated with the issuance of the call option. The fair value of the call option upon issuance and subsequently is immaterial.

Although legally issued, the Group has not considered the Loaned Shares issued for accounting purposes. As a result, any cash collateral, to the extent posted by the ADS Borrower, is not considered attributable to the issuance of shares. To the extent cash collateral is posted, the Group recorded the cash as an asset on its balance sheet with an offsetting liability recorded to reflect the collateral receipt as the proceeds of a borrowing. The cash collateral posted as of December 31, 2009 and 2010 is $20,471,220 and $18,521,580 which is recorded as a long-term asset under restricted cash collateral account with an offsetting long term liability recorded in collateral accounts payable as of December 31, 2009 and 2010.

During the 2008 and 2009, the Group conducted open market repurchase of its Convertible Notes, and repurchased $6.5 million and $4.0 million aggregate principal amount of the Convertible Notes for a total cash consideration of $2.0 million and $1.8 million, respectively. As a result, the Group realized a net gain of $4.5 million and $2.2 million and recorded as other income.

13. MAINLAND CHINA CONTRIBUTION PLAN

Full time employees of the Group in the PRC participate in a government-mandated multiemployer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. PRC labor regulations require the Group to accrue for these benefits based on certain percentages of the employees’ salaries. The total contribution for such employee benefits was $2,240,492, $2,467,789 and $3,744,032 for the years ended December 31, 2008, 2009 and 2010, respectively.

14. PROFIT APPROPRIATION

Pursuant to laws applicable to entities incorporated in the PRC, PRC subsidiaries such as Sunergy Nanjing, Sunergy Shanghai, SST and NRE, are prohibited from distributing their statutory capital and must make appropriations from PRC GAAP after-tax profit to other non-distributable reserve funds. These reserve funds include one or more of the following: (i) a general reserve, (ii) an enterprise expansion fund and (iii) a staff bonus and welfare fund. Subject to certain cumulative limits, the general reserve fund requires annual appropriation of 10% of after tax profit (as determined under accounting principles generally accepted in the PRC at each year-end); the appropriation to the other fund are at PRC subsidiaries’ discretion. These reserve funds can only be used for specific purposes of enterprise expansion and staff bonus and welfare and are not distributable as cash dividends, loans or advances to the Company. Due to a net loss in 2008 and 2009, PRC subsidiaries made no appropriation to other non-distributable reserve funds.

As a result of these PRC laws and regulations, PRC subsidiaries are restricted in its ability to transfer the registered capital to the Company in the form of dividends, loans or advances. The restricted portion amounted to $143,183,283 as of December 31, 2010.

British Virgin Islands

China Sunergy BVI is not subject to tax on income or capital gain according to the current laws of the British Virgin Islands.

Hong Kong

Sunergy Hong Kong is subject to Hong Kong profit tax at a rate of 17.5% as of March 31, 2008 and 16.5% effective from April 1, 2008. No Hong Kong profit tax has been provided as Sunergy Hong Kong has no assessable profit that was earned in or derived from Hong Kong in periods presented.

PRC

Under the Law of the People’s Republic of China on Enterprise Income Tax (“New EIT Law”), which was effective from January 1, 2008, domestically-owned enterprises and foreign-invested enterprises are subject to a uniform tax rate of 25%.

Sunergy Nanjing, as a recognized High and New Technology Enterprise (“HNTE”), is entitled to a two-year exemption and three-year 50% reduction in EIT starting from 2006. The EIT rate is 12.5% for Sunergy Nanjing in 2010. Since Sunergy Nanjing’s certificate of HNTE need to be renewed in 2011, management applied the 25% income tax rate in the deferred tax calculation.

Sunergy Shanghai was established in November 2007 and its applicable EIT rate is 25%. Sunergy Shanghai did not have substantive operations and had incurred minimal non-operating related losses.

SST was acquired in November 2010, which obtained the certificate of HNTE in 2009, with a valid period from 2009 to 2011, and thus is eligible for a 15% preferential tax rate during the periods above.

NRE was acquired in November 2010 and its applicable EIT rate is 25%.

The Group has no uncertain tax positions as of December 31, 2009 and 2010 or unrecognized tax benefits which would favorably affect the effective income tax rate. The Group does not anticipate any significant increases or decreases to its liabilities for unrecognized tax benefits within the next 12 months.

According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of income taxes is due to computational errors made by the taxpayer. The statute of limitations will be extended to five years under special circumstances, which are not clearly defined, but an underpayment of income tax liability exceeding RMB100,000 is specifically listed as a special circumstance. In the case of a transfer pricing related adjustment, the statute of limitations is ten years. There is no statute of limitations in the case of tax evasion. The statute of limitations in Hong Kong is 6 years.

The tax losses carryforwards arising from year 2008 and 2009 of Sunergy Nanjing are approximately $645,784 and $19,799,450 respectively, which were used in 2010.

The Group considers positive and negative evidence to determine whether some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible for tax purposes. Based upon the projections for future taxable income over the periods in which the deferred tax assets are realizable, the Group believes it is more-likely-than-not that Sunergy Nanjing, SST and NRE will realize the benefits of those deductible differences, and as such, no valuation allowances as of December 31, 2010 have been provided. The amount of the deferred tax assets considered to be realizable, however, could be reduced in the near term if estimates of future taxable income during the tax loss carry forward periods are reduced.

Based on the current profit, projected future profitability, and other available evidence, the Group believes it is more-likely-than-not that Sunergy Hong Kong and Sunergy Shanghai will not realize the deferred tax assets resulted from the tax loss carried forward in the future periods. Thus, a full valuation allowances are provided for the deferred tax assets of Sunergy Hong Kong and Sunergy Shanghai.

In accordance with the New EIT Law, dividends, which arise from profits of foreign invested enterprises (“FIEs”) earned after January 1, 2008, are subject to a 10% withholding income tax. Under applicable accounting principles, a deferred tax liability should be recorded for taxable temporary differences attributable to the excess of financial reporting basis over tax basis in a domestic subsidiary unless the profits are essentially permanent in duration. As of December 31, 2010, the Company’s PRC subsidiaries have an accumulated earning of $14.3 million. As the Group plans to indefinitely reinvest the undistributed earnings of the Company’s PRC subsidiaries, no dividend withholding tax has been accrued.

17. SHARE-BASED COMPENSATION

Prior to January 1^st, 2008, pursuant to the company’s Share Incentive Plan which allows the Company to offer share incentive awards to employees, officers, directors, individual consultants or advisors who rendered services to the Group, 2,500,000 options were authorized and 2,050,900 options were granted, which generally vest over four years and have a 10-year contract term.

consultants as determined by the Compensation Committee of the Board. The maximum number of shares that may be issued pursuant to the Second Plan is 4,190,748. The Company granted 2,397,301 and 1,078,785 restricted common shares to its then CEO and CFO on the same day, which vest one third annually over the following three years.

On January 9, 2009, the Group granted options to purchase 260,002 and 80,640 ordinary shares to certain employees at an exercise price of US$1.283 and US$0.7 per share, respectively. The options expire ten years from the date of grant, with one-fourth of the options vesting on each of the following four grant date anniversaries. At the same date, the Group also granted options to purchase 100,002 ordinary shares to a consultant at an exercise price of US$0.7 per share. The shares subject to the option was vested on the December 31, 2009 and is exercisable within 5 years from the date the option is vested.

In 2010, the Group didn’t grant any additional options to employees.

The Group recorded $3,231,594 and $1,327,033 and $543,510 as compensation expense for the years ended December 31, 2008, 2009 and 2010, respectively.

The Group records share-based compensation based on the grant date fair value of the option. The weighted average grant-date fair value of options granted during year 2008 and 2009 was $1.20 and $0.22 per share, respectively, computed using the binomial option-pricing formula that uses the assumptions noted below. Expected volatilities are based on the average volatility of comparable companies with the time period commensurate with the expected time period. The Group uses historical data to estimate option exercise and employee termination within the pricing formula. The contractual life of the option is 6 to 10 years. The risk-free rate for periods within the contractual life of the option is based on the yield of US Treasury Bond.

	2008			2009
Average risk-free rate of return		3.91	%		1.51% ~ 2.40	%

In 2009, the Company agreed to settle a securities class action that was filed against it on September 7, 2007 in the United States District Court for the Southern District of New York on behalf of purchasers of the Company’s American Depositary Shares during the period from May 17, 2007 through August 23, 2007. The proposed settlement agreement, filed with the court on October 16, 2009, was still pending and must be approved by the court before become final. The Company recorded its best estimate of the probable amount of $1.05 million for the final settlement in the consolidated financial statements as of and during the year ended December 31, 2009. The Company is currently awaiting the hearing for final approval of the settlement, set by the Court for May 12, 2011.

(2) Dispute with REC

On September 9, 2009, REC Wafer announced that it terminated a long-term take-or-pay contract with the Group for deliveries of mono wafers. REC Wafer called upon a USD 50 million bank guarantee established by the Group to cover the Group’s possible future payment obligations.

The Group has served a writ to REC claiming that REC Wafer is not a party to the contract originally entered into between China Sunergy and the dissolved REC Sitech.

In parallel, the Group requested an injunction to prevent REC Wafer from accessing the bank guarantees. The Court of Appeal has granted the injunction and ordered that Nordea Bank Norge ASA is prohibited from making payment and REC Wafer is prohibited from receiving payment from the US$50 million bank guarantees issued by Nordea Bank Norge ASA to REC Sitech AS. The injunction will remain in force until the Court of Appeal makes a ruling on the main dispute.

The court proceeding in Norway regarding the main dispute is still ongoing. The Norwegian District Court ruled on July 5, 2010 in favor of REC Wafer. The Group appealed the ruling at the Court of Appeal, claiming REC Wafer is not a party to the contract originally entered between the Group and the dissolved REC Sitech AS. The Court of Appeal hearing, originally scheduled for March 2011, will now be held in June 2011.

The Group will vigorously defend its interests and will continue to monitor the developments of the REC legal proceedings under both PRC and Norwegian courts. As of December 31, 2010, the Group believes the outcome of the dispute and related litigation proceedings is still uncertain and the present situation does not enable the Group to reasonably estimate either the likelihood or an amount of the potential outcome.
