Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies and Significant Concentrations and Risks ( Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably and to generate cash flows from operations, and the ability to pursue financing arrangements, including the renewal or rollover of its bank borrowings, to support its working capital requirements and its obligations and commitments on loans and borrowings when they become due. For the year ended December 31, 2015, the Company incurred a net loss of RMB 5,898,836 910,623 As of December 31, 2015, the Company 5,939,684 916,929 7,257,335 1,120,339 1,587,675 245,095 9,124,183 1,408,531 2,405,898 371,407 300,000 46,312 1.1 163.2 700,000 108,061 accrued 1.45 224.5 that became The Company has carried out a review of its cash flow forecast for the twelve months ending December 31, 2016. In preparing the cash flow forecast, the Company’s management has considered historical cash requirements of the Company, the Company’s expected debt repayment obligations in 2016, the Company’s plan to further reduce operating costs and expenses, as well as the alternative financing plans discussed in detail below. The Company’s management also made the assumption that there will be no significant decrease of the Company’s shipments of modules and gross profit margin. Alternative Financing Plans The Company is currently exploring a variety of alternative financing plans to improve the Company’s liquidity and financial position. Debt Restructuring and Introducing Strategic Investors As of December 31, 2015, the Company had medium-term notes of RMB 2,057,000 357,000 October 13, 2015 1,400,000 May 12, 2016 300,000 May 3, 2017 The Company is also in negotiation proactively with certain investors for potential strategic investments in the Company or its major subsidiaries. Such debt restructuring and strategic investments, if successfully completed, will further increase the liquidity of the Company and improve its debt-to-equity ratio. Renewal or Rollover of Borrowings and other Financing Arrangements The Company has maintained good credit records and relationships with its lending banks and other financial institutions in China. In addition, the Company has obtained financing through other arrangements, such as sale and lease back of certain machinery and equipment and sale and repurchase of certain equity interest in its subsidiary. The Company has failed to fulfill its payment obligations under some of these arrangements in the past. As of December 31, 2015, the Company had RMB 175 million of payment obligation overdue under its agreement with a leasing company for sale and lease back of certain machinery and equipment and RMB 100 million of payment obligation overdue under its agreement with a third party for sale and repurchase of 5.50% equity interest of Hainan Yingli. As of December 31, 2015, the Company recorded the RMB 175 million and RMB 100 million of payment obligation overdue as borrowings and payables, respectively. The Company is still in negotiation with these third parties about the extension of our payment schedules under the relevant agreements. There can be no assurance, however, that such expected financing plans will be successfully completed or completed on terms acceptable to the Company. The Company ’ (b) Principles of Consolidation The accompanying consolidated financial statements include the accounts of Yingli Green Energy and its subsidiaries. For consolidated subsidiaries where the Company’s ownership in the subsidiary is less than 100 The Company applies the guidance codified in Accounting Standard Codification 810, Consolidations (“ASC 810”) on accounting for VIEs and their respective subsidiaries, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns, or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor. Accordingly, the financial statements of the VIEs and VIEs’ subsidiaries are consolidated into the Company’s financial statements. In 2014, the Company signed several contracts with Yingli PV Investment Group Co., Ltd. (“Yingli PV Group”) to construct all project assets on behalf of the Company. Each project asset is owned by a special purpose entity which is owned 100 100 23 In September 2015, the Company entered into an agreement with Yingli PV Group to terminate the above-mentioned construction contracts and the Company was no longer entitled to any rights or undertook any obligations under the aforementioned contracts. As a result, the Company disposed all the project assets under the VIE structure to Yingli PV Group. Total consideration for disposal of all entities under the VIE structure was RMB 554,452 85,593 6,852 1,058 561,304 86,650 1,886,045 1,324,741 In 2015, the Company also entered into three separate agreements with three entities unrelated to the Company to transfer the Company’s 100 28,430 4,389 30,002 4,631 1,572 243 180,752 179,180 (c) Significant Concentrations and Risks Revenue concentrations The Company’s business depends substantially on government incentives given to its customers. In many countries in which the Company sells its products, the market of the Company’s products would not be commercially viable on a sustainable basis without government incentives. This is largely in part caused by the cost of generating electricity from solar power currently exceeding and that is expected to continue to exceed the costs of generating electricity from conventional energy sources. The Company generated approximately 90 88 93 Year ended December 31, % of net December 31, % of net % of net 2013 revenue 2014 revenue December 31, 2015 revenue RMB RMB RMB US$ PRC 4,546,482 34 % 4,550,915 35 % 4,078,476 629,608 41 % Japan 972,604 7 % 2,487,949 19 % 2,723,800 420,482 27 % USA 2,906,262 22 % 2,301,496 18 % 1,248,536 192,741 12 % Turkey 22,118 0 % 118,305 1 % 550,799 85,029 5 % France 156,557 1 % 191,071 1 % 363,635 56,136 4 % Germany 2,439,058 18 % 671,534 5 % 170,518 26,323 2 % England 403,014 3 % 998,203 8 % 80,255 12,389 1 % Total 11,446,095 85 % 11,319,473 87 % 9,216,019 1,422,708 92 % The Company derived significant revenue from sales outside of the PRC. As a result, the Company’s financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures and changes in regional or worldwide economic or political conditions. Management currently expects that the Company’s operating results will, for the foreseeable future, continue to depend on the sale of PV modules to a relatively small number of customers. The Company’s relationships with such key customers have been developed over a short period of time and are generally in their preliminary stages. Any factors adversely affecting the business operations of these customers could have a material adverse effect on the Company’s business and results of operations. In 2013, 2014 and 2015, sales to the top five customers accounted for approximately 15.2 13.9 19.4 10 As of December 31, 2014 and 2015, the top five outstanding accounts receivable balances (net of provisions) accounted for approximately 27.2 27.6 10 10 Dependence on suppliers Polysilicon is the most important raw material used in the production of the Company’s PV products. To maintain competitive manufacturing operations, the Company depends on timely delivery by its suppliers of polysilicon in sufficient quantities. The Company’s failure to obtain sufficient quantities of polysilicon in a timely manner could disrupt its operations, prevent it from operating at full capacity or limit its ability to expand as planned, which will reduce the growth of its manufacturing output and revenue. In order to secure a stable supply of polysilicon and other raw materials, the Company makes prepayments to certain suppliers. Such amounts are recorded as prepayments to suppliers, prepayments to related party suppliers (included in “Amounts due from and prepayments to related parties”), and “Long-term prepayments to suppliers” in the Company’s consolidated balance sheets and amounted to RMB 1,681,562 1,212,614 187,195 December 31, 2014 2015 Location RMB RMB US$ Supplier A Singapore 212,612 224,029 34,584 Supplier B South Korea 158,613 158,613 24,486 Supplier C Germany 784,866 277,392 42,822 Total 1,156,091 660,034 101,892 The Company obtains some equipment to be used in its manufacturing process from a small number of selected equipment suppliers. In addition, some equipment has been customized based on the Company’s specifications, is not readily available from multiple vendors and would be difficult to repair or replace. If any of these suppliers were to experience financial difficulties or go out of business, the Company may have difficulties in repairing or replacing its equipment in the event of any damage to the manufacturing equipment or a breakdown of the production process. The Company’s ability to deliver products timely would suffer, which in turn could result in order cancellations and loss of revenue. A supplier’s failure to deliver the equipment in a timely manner with adequate quality and on terms acceptable to the Company could delay its capacity expansion of manufacturing facilities and otherwise disrupt its production schedule or increase its costs of production.

To limit exposure to credit risk relating to bank deposits, the Company primarily places bank deposits with large financial institutions in the PRC with acceptable credit rating. As of December 31, 2014 and 2015, the Company had cash balances at two and one PRC individual financial institutions, respectively, that held cash balances in excess of 10% of the Company’s total cash balances. These bank deposits collectively accounted for approximately 37.2 34.4 (d) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities as well as with respect to the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the fair values of assets acquired and liabilities assumed in business acquisitions, the useful lives of property, plant and equipment and intangibles with definite lives, recoverability of the carrying values of property, plant and equipment, and intangible assets, the fair value of share-based payments, the collectability of accounts receivable, the realizability of inventories, prepayments and deferred income tax assets, the fair values of financial and equity instruments, the accruals for warranty obligations and loss contingency, and provision for inventory purchase commitments. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions. (e) Foreign Currency The Company’s reporting currency is the Renminbi (“RMB”). Assets and liabilities of foreign companies whose functional currency is not RMB are translated into RMB using the exchange rate on the balance sheet date. Revenues and expenses are translated at average rates prevailing during the year. Gains and losses resulting from the translation of financial statements of foreign companies are recorded as a separate component of accumulated other comprehensive income within shareholders’ equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. The resulting exchange differences are recorded in “foreign currency exchange gains (losses)” in the Consolidated Statements of comprehensive Loss. Transaction gains and losses resulting from intercompany foreign currency transactions that are of a long-term investment nature are treated in the same manner as translation adjustments and therefore excluded from the determination of net loss. RMB is not freely convertible into foreign currencies. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (“PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC. For the convenience of readers, certain 2015 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.4778 ( Cash, Cash equivalents and Restricted Cash Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less. Restricted cash of RMB 1,332,404 346,926 53,556 ( Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance for doubtful accounts is based on a review of specifically identified accounts and aging data. Judgments are made with respect to the collectability of accounts receivable balances based on historical collection experience, customer specific facts and current economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Sale of Accounts Receivable In 2013 and 2014, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyers were responsible for servicing the receivables. The accounts receivables were determined to be legally isolated from the Company and its creditors, even in the event of bankruptcy or other receivership and the Company had surrendered control over the transferred receivables. As a result, the accounts receivables were considered sold and were therefore derecognized. The Company received proceeds from the sale of accounts receivable of RMB 677,795 188,117 11,840 8,885 Inventories Inventories are stated at the lower of cost or market. Cost is determined by using the weighted-average cost method. Cost of work-in-progress and finished goods are comprised of direct materials, direct labour, and an allocation of related manufacturing overhead based on normal operating capacity. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. Certain factors could impact the realizable value of inventory, so the Company continually evaluates the recoverability based on assumptions about customer demand and market conditions. The evaluation may take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer concentrations, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that could negatively impact the Group’s gross margin and operating results. If actual market conditions are more favorable, the Company may have higher gross margin when products that have been previously written down are eventually sold. ( Prepayments to Suppliers Advance payments for the future delivery of raw materials are made based on written purchase orders detailing product, quantity, pricing and are classified as “prepayments to suppliers” in the consolidated balance sheets. The Company’s supply contracts grant the Company the right to inspect products prior to acceptance. The amount in the balance of the “prepayments to suppliers” is and reclassified to “inventories” when inventory is received and passes quality inspection. Such reclassifications of RMB 245,906 340,007 318,132 49,111 23,338 144,803 721,651 555,520 85,758 For the years ended December 31, 2013, 2014 and 2015, provisions of RMB 87,134 522,050 80,591 Long-lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the asset, taking into consideration any estimated residual value, using the straight-line method. When items are retired or otherwise disposed of, income is charged or credited for the difference between net book value and proceeds received thereon. Ordinary maintenance and repairs are charged to expense as incurred, and replacements and betterments are capitalized. Buildings 30 Machinery and equipment 4 25 Furniture and fixtures 3 5 Motor vehicles 8 10 Depreciation of property, plant and equipment attributable to manufacturing activities is capitalized as part of the cost of inventory production, and expensed to cost of revenues when the inventory is sold. Cost incurred in the construction of new facilities, including progress payments and deposits, interest and other costs relating to the construction, are capitalized and transferred out of construction in progress and into their respective asset categories when the assets are ready for their intended use, at which time depreciation commences. Leases Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Other leases are accounted for as capital leases. Payments made under operating leases, net of any incentives received by the Company from the leasing company, are charged to the consolidated statements of comprehensive loss on a straight-line basis over the lease periods. Leases that qualify as capital leases are recorded at the lower of the fair value of the asset or the present value of the future minimum lease payments over the lease term generally using the Company’s incremental borrowing rate. Assets leased under capital leases are included in property, plant and equipment and generally are depreciated over the lease term. Lease payments under capital leases are recognized as a reduction of the capital lease obligation and interest expense. For a sale-leaseback transaction, an analysis is performed to determine if the Company can record a sale and remove the assets from the balance sheet and recognize the lease; and if so, to determine whether to record the lease as either an operating or capital lease. If the Company has continued involvement beyond a normal lease, the lease is accounted for as a capital lease transaction and the assets and related financing obligation are recognized on the balance sheet. The Company’s assets under the capital lease transaction were derecognized upon sale at the net book value and rebooked at the financed amount; and the differences between the net book value derecognized and the rebooked financed amount of the assets were deferred and amortized over the lease term. Accordingly, the asset is depreciated over its estimated useful life in accordance with the Company’s policy. When the assets transaction does not qualify as a sale-leaseback transaction, it will be treated as a financing transaction. If the sale-leaseback transactions involve asset other than real estate, those are evaluated to determine whether they are considered integral with real estate, in which case the sale-leaseback rules related to real estate are applied. Refer to note (16) to the consolidated financial statement. Project assets Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the sale of the solar power project. These costs include modules, installation and other development costs. If a project is completed and begins commercial operation prior to entering into a sales agreement, which is at the point when the solar power plant is connected to grids and begins to generate electricity, costs capitalized in the construction of solar power plants under development will be transferred to solar power plants upon completion and when they are ready for its intended use. Any income generated by such project is accounted for as revenue. Depreciation is provided over the estimated useful lives of the projects assets ( 20-25 years), taking into consideration any estimated residual value, using the straight-line method, and expensed to cost of revenues. As of December 31, 2015, project assets with carrying value of RMB 235,229 36,313 485,057 74,880 For the years ended December 31, 2013, 2014 and 2015, revenue related to the projects assets from power generation were nil, RMB 2,015 30,836 4,760 2,365, 37,855 5,844 . Other Intangible Assets Trademarks that have an indefinite useful life are not amortized, but instead are tested for impairment at least annually. Intangible assets, other than trademarks, are amortized on a straight-line basis over the estimated useful lives of the respective assets. 5.5 6 Customer relationships 5.5 6 Order backlog 1 1.5 Short-term supply agreements 0.5 Impairment of Long-Lived Assets Long-lived assets, such as property, plant, and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Intangible assets that are not subject to amortization are tested annually for impairment at December 31, and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. For intangible assets that are not subject to amortization, an impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. For the years ended December 31, 2013 and 2014, no impairment loss arose on long-lived assets. For the year ended December 31, 2015, a total impairment loss against property, plant and equipment amounted to RMB 3,804,116 587,254 Government grant Government grants are recorded in the balance sheet when they are received and that the Company will comply with the conditions attaching to them. Government grants, which are obtained by the Company for the purposes of purchase, construction or acquisition of the long-term assets, will be recorded as “Deferred other income” and included in “Deferred other income” in the Consolidated Balance Sheets and are depreciated or amortized evenly over the useful lives of the related assets. For the years ended December 31, 2013, 2014 and 2015, the Company received government grants of RMB 350,028 80,849 74,581 11,513 53,419 49,557 56,935 8,789 Government grants other than those related to assets, will be recorded as “Deferred other income” and recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss in the period in which the related expenses are recognized if the grants are intended to compensate for future expenses or losses, and otherwise recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss for the current period if the grants are used to compensate for expenses or losses that have been incurred. Land and Land Use Rights Land represents the cost of land acquired outside the PRC with indefinite useful life. Land use rights represent the cost of rights to use land in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the respective periods of the rights of 45 50 (l) Equity Investments Investments in entities where the Company does not have a controlling financial interest, but has the ability to exercise significant influence over the operating and financial policies of the investees, are accounted for using equity method accounting. Under the equity method accounting, the Company’s share of the investees’ results of operations is included in “Equity in Income/Loss of Affiliates” in the Company’s Consolidated Statements of Comprehensive Loss. Equity investments are accounted for under cost method when the Company does not have the ability to exercise significant influence over the operating and financial policies of the investees. Under the cost method of accounting, the Company records an investment in the equity of an investee as cost, and recognizes as income dividends received that are distributed from net accumulated earnings of the investee since the date of acquisition. The Company does not have available-for-sale investment. In case the Company sells modules to its equity method investee, the profit derived from the transaction is eliminated to the extent of the Company’s shares in that investee, and the income is credited against “Investments in affiliated companies” in the Consolidated Balance Sheets and deferred until the project assets are ultimately sold to external customers. The Company recognizes a loss when there is a loss in value of an equity investment which is other than a temporary decline. The process of assessing and determining whether an impairment on a particular equity investment is other than temporary requires a significant amount of judgment. To determine whether an impairment is other-than-temporary, management considers whether the Company has the ability and intent to hold the investment until recovery and whether evidence indicating the carrying value of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the decline in value, any change in value subsequent to year end, and forecasted performance of the investee. ( Statutory Reserves In accordance with the relevant laws and regulations of the PRC, PRC enterprises are required to transfer 10 50 499,383 500,164 77,212 Derivative Financial Instruments and Hedging Activities The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are either offset through earnings against the change in fair value of the designated hedged item attributable to the risk being hedged or recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings. The Company enters into derivative contracts that it intends to designate as a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For all hedging relationships, the Company formally documents the hedging relationship and its risk management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company also formally assesses, both at the inception of the hedging relationship and on an ongoing basis, whether the derivatives that are used in hedging relationships are highly effective in offsetting changes in cash flows of hedged transactions. For derivative instruments that are designated and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The maximum term over which the Company is hedging exposures to the variability of cash flows for forecasted transaction is 12 months. The Company discontinues hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedged risk, the derivative expires or is sold, terminated, or exercised, the cash flow hedge is designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in in the Consolidated Statement of Comprehensive loss. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in the Consolidated Statement of Comprehensive loss gains and losses that were accumulated in other comprehensive income related to the hedging relationship. Share-based Payment The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the costs over the period the employee is required to provide service in exchange for the award, which generally is the vesting period. The Company estimates grant date fa

Due to the significant decrease in shipment, gross profit margins and lower-than-expected utilization of production facilities, the Company determined a two-step impairment analysis was required in the middle of 2015. In step one impairment analysis, the estimated future undiscounted net cash flows expected to be generated by the assets over their remaining estimated useful lives were based on certain assumptions, such as forecasts of future operating results, gross margin and expected future growth rates. The estimated undiscounted future cash flows generated by the equipment used to produce solar products were less than their carrying value, which required the step two impairment test. In the step two impairment analysis, the Company estimated the fair value based on discounted cash flow analysis using market participants’ assumptions, such as forecasts of future operating results, discount rates commensurate with the risk involved, and expected future growth rates. The carrying value of the equipment was reduced to fair value based on the discounted cash flow analysis. As a result, an impairment loss of RMB 3,804,116 587,254 Depreciation expense on property, plant and equipment was allocated to the following expense items: Year ended December 31, 2013 2014 2015 RMB RMB RMB US$ Cost of revenues 1,192,906 1,292,586 1,086,392 167,710 Selling expenses 1,813 16,475 7,530 1,162 General and administrative expenses 60,029 48,963 60,268 9,304 Research and development expenses 24,573 30,260 20,515 3,167 Total depreciation expense 1,279,321 1,388,284 1,174,705 181,343 For year ended December 31,2015, due to the impairment loss of RMB3,804,116 (US$ 587,254) was recorded during the middle of the year, total depreciation expenses for the year decreased by approximately RMB 242.7 37.5 The Company capitalized interest costs as a component of the cost of construction in progress as follows: Year ended December 31, 2013 2014 2015 RMB RMB RMB US$ Interest cost capitalized 53,998 8,624 37,452 5,782 Interest cost charged against income 971,597 1,015,871 977,176 150,850 Total interest cost incurred 1,025,595 1,024,495 1,014,628 156,632 As of December 31, 2014 and 2015, the Company had pledged property, plant and equipment with a total carrying amount of RMB 10,213,355 4,001,055 617,656 In December 2014, Yingli China sold certain machinery and equipment with carrying amount of RMB 405,282 400,000 7 403,191 62,242 In February 2015, right after Yingli China repaid total instalment of RMB 400,000 300,000 300,000 1,750 300,000 250,000 250,000 28,000 250,000 75,000 175,000 27,015 175,000

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	(7) Derivative Instruments and Hedging Activities The Company uses foreign currency forward contracts to manage its exposure to foreign currency risks arising from sales denominated in foreign currency and uses interest rate related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not speculate using derivative instruments. Foreign Currency The Company’s principal operating subsidiaries, Hainan Yingli New Energy Resources Co., Ltd. (“Hainan Yingli”) and Yingli Energy (China) Co., Ltd. (“Yingli China”) are located in the PRC with the Renminbi being their functional currency, respectively. However, the majority of these two entity’s sales are in currencies other than Renminbi, primarily the EURO and US$. Any depreciation of the EURO or US$ against the Renminbi will generally result in foreign exchange losses and adversely affect the Company’s results of operations. With an aim to reduce its risk exposure, the Company, on a selected basis, enters into forward contracts with financial institutions to forward sell EURO or US$ when it entered into certain sales contracts denominated in EURO or US$ through its PRC operating subsidiaries. Some of these foreign currency forward contracts are qualified as foreign currency cash flow hedges at inception, and thus the change in the fair value of these hedge contracts were initially recognized in accumulated other comprehensive income and reclassified into the consolidated statements of comprehensive loss in the period that the sale of the related hedged item is recognized or when hedge accounting is discontinued if the foreign currency forward contracts are no longer effective in offsetting cash flows attributable to the hedged risk. During the year ended December 31, 2013, the Company entered into foreign currency forward contracts with a notional amount of EURO 100,690 7,000 31,760 27,000 2,499,200 80,000 30,000 7,100,000 3,780 Interest The Company’s exposure to the risk of changes in market interest rates primarily relates to its bank borrowings. To finance its business operation and expansion, the Company’s PRC operating subsidiaries will obtain short-term and long-term bank borrowings. Some of the bank borrowings carry variable interest rates. Interest expenses on these banking borrowings may increase as a result of change in market interest rates. With an aim to reduce its interest rate exposure, the Company entered into one long-term interest rate swap contract, with notional amount of US$ 70,000 Balance Sheet Classification Fair Value 2014 2015 Balance Sheet Classification RMB RMB US$ Assets: Foreign currency contract Prepaid expenses and other current assets 4,195 — — Total derivatives designated as hedges 4,195 — — Cash Flow Hedge Loss or Gain Recognition Location of Gain Amount of Gain Amount of Gain Reclassified from Reclassified from Recognized in Other Other Other Comprehensive Comprehensive Comprehensive Income into Derivatives in Cash Flow Income Income into Loss Hedging Relationships RMB US$ Loss RMB US$ 2013 Foreign currency contracts (7,641) Foreign currency exchange losses (8,711) 2014 Foreign currency contracts (24,117) Foreign currency exchange losses (24,390) 2015 Foreign currency contracts — — Foreign currency exchange losses (749) (116) Other Derivatives Gains (Losses) Recognition Amount of Loss Recognized in Income on Location of Loss Derivative Recognized in Income 2013 2014 2015 on Derivative RMB RMB RMB US$ Derivatives Not Designated as Hedging Instruments Interest rate swap Interest expense (103) (81) — — Total (103) (81) — —

The significant unobservable inputs used in the valuation of the fair value of the asset group subject to impairment are as following: ⋅ Weighted average cost of capital, or WACC—The WACCs were determined based on a consideration of such factors as risk-free rate, comparative industry risk, equity risk premium, company size and company-specific factors. The Company used WACC of 15.0 ⋅ Comparable companies—In deriving the discounted cash flow and WACCs, which are used as the discount rates under the discounted cash flow, three to four publicly traded solar companies were selected for reference as market participants. (b) Fair Value of Financial Instruments Management used the following methods and assumptions to estimate the fair value of financial instruments at the relevant balance sheet dates: ⋅ Foreign currency forward contract — as of December 31, 2014 and 2015, the fair value is determined by discounting estimated future cash flow, which is based on the changes in the forward rate. ⋅ Interests swap contract — as of December 31, 2014 and 2015 the fair value is determined by using pricing models developed based on the London Interbank Offered Rate (“LIBOR”) swap rate and other unobservable market data. ⋅ Short-term financial instruments (cash and cash equivalents, restricted cash, accounts receivable, amounts due from related parties, accounts payable, short-term borrowing, and amounts due to related parties) - cost approximates fair value because of the short maturity period. ⋅ Long-term debt and long-term payable (included in other liabilities) - fair value is based on the amount of future cash flows associated with each debt instrument discounted at the Company’s current borrowing rate for similar debt instruments with comparable terms. As of December 31, 2015, the carrying values of the Company’s long term debt and long-term payable approximate their fair values as all the long-term borrowings carries variable interest rates which approximate rates currently offered by the Company’s bankers for similar debt instruments of comparable maturities. ⋅ Medium-term notes — fair value is based on the amount of future cash flows associated with the debt instrument discounted at the Company’s current borrowing rate for similar debt instruments with comparable terms. As of December 31, 2015, the fair value of the Company’s medium term notes, based on Level 2 inputs, was RMB 253,811 39,182

Inventory Purchase Commitments

Inventory Purchase Commitments Disclosure [Abstract]
Inventory Purchase Commitments [Text Block]	(18) Inventory Purchase Commitments Until the third quarter of 2008, an industry-wide shortage of high purity polysilicon coupled with growing demand for PV modules caused the increases of polysilicon prices. In order to ensure the adequate supply of polysilicon, the Company entered into several long-term fixed price supply contracts from 2006 to 2011 under which the polysilicon would be delivered from 2009 to 2020. However, from the second quarter of 2011, the polysilicon price has decreased significantly as the result of increased polysilicon manufacturing capacity and the pressure from the decreasing average selling price of PV modules. As a result, the Company recognized a provision of RMB 851,694 on its firm purchase commitments under the long-term fixed price polysilicon contracts as of December 31, 2011. The provision was determined by applying a methodology similar to that used in the lower of cost or market evaluation with respect to inventory. During the years ended December 31, 2011 and 2012, notwithstanding that the firm purchase commitments under the long-term fixed price contracts continued to be in effect, through negotiations with the vendors the Company was able to obtain various pricing concessions from the vendors which resulted in the actual purchase price paid by the Company to be less than the stated contract price. The Company has therefore reclassified the accrual for potential losses on inventory firm purchase commitments of RMB 851,694 During the year ended December 31, 2013, the Company continued to negotiate and execute amendments for current purchases on a monthly or quarterly basis with Supplier B and Supplier C(refer to note (2)(c)) and obtained price concessions that allowed the Company to purchase polysilicon at renegotiated prices that were in line with the market price and significantly lower than the stated contract prices under the long-term fixed price supply contracts with these vendors. In addition, the Company continued to negotiate with these Supplier B and Supplier C for an overall amendment to each long-term fixed price supply contract with such vendors to eliminate fixed price arrangements. In October 2013, the Company entered into agreements with Supplier B to amend the contract and include a price adjustment mechanism that allows the Company and the vendor to renegotiate purchase price on a quarterly basis within a specified price range set forth in the amendments based on market price. The Company has not reached similar agreement with Supplier C, but continued to renegotiate prices on a quarterly or monthly basis to purchase at close to market prices. The Company failed however, to purchase from Supplier C the stated quantities for a total of six months in 2012 and 2013 under the long-term fixed price supply contracts as the Company’s management determined after taking into consideration all relevant factors that it would be in the Company’s best interest not to accept those deliveries when they were due. As a result, because the contract has been substantially executed, Supplier C claimed that the Company had forfeited certain advance payments made by the Company (see below for discussion of provision recorded in 2013 against these advances). Notwithstanding the Company’s failure to accept deliveries for six months and Supplier C’s claim as described above, the Company and Supplier C continued their monthly or quarterly negotiations and the Company has accepted deliveries from Supplier C after its failure to accept deliveries in those six months. In connection with the preparation of the Company’s consolidated financial statements for the year ended December 31, 2013, management reassessed the loss contingency under the long-term fixed price polysilicon contracts taking into account the developments described above as well as considerations related to the more recent long-term fixed price polysilicon contracts with another supplier, Supplier A, the Company recognized an additional provision of RMB 393,048 As of December 31, 2013 and December 31, 2014, the total accrual for loss on inventory purchase commitments remained RMB 1,331,877 87,134 13,042 2,102 1,231,701 198,514 (a) Development on the inventory firm purchase commitment with Supplier A for the years ended December 31, 2014 and 2015 As of December 31, 2013, the total liability recognised for loss on inventory purchase commitments of RMB 1,244,743 87,134 In 2015, after management’s assessment by using same methodology mentioned above, no additional contingency losses for inventory firm purchase commitment with Supplier A was determined to be required in 2015. However, due to significant fluctuation in the foreign exchange rates between the RMB and US$ and given that the inventory purchase commitment to Supplier A is dominated in US dollar, which is different from the related entities’ functional currency, a foreign exchange re-measurement loss of RMB 77,705 11,996 As of December 31, 2014 and December 2015, the total reserve for inventory purchase commitment of Supplier A was RMB 1,244,743 1,322,448 204,151 13,042 1,231,701 1,322,448 204,151 Year ended December 31, 2013 2014 2015 RMB RMB RMB US$ Beginning balance (851,694 ) (1,244,743 ) (1,244,743 ) (192,155 ) Additions (393,048 ) - (77,705 ) (11,996 ) Ending balance (1,244,743 ) (1,244,743 ) (1,322,448 ) (204,151 ) In entering into its inventory purchase contracts with Supplier A, the Company made prepayments as described in note 2(c). As of December 31, 2014 and 2015, total balance of prepayments made to Supplier A was RMB 224,029 34,584 1.6 (b) Development on the inventory firm purchase commitment with Supplier C for the years ended December 31, 2014 and 2015 As described in note 2(c), the Company also has prepayments with respect to another supplier, Supplier C, for the purchase of polysilicon. In 2015, the Company failed to purchase from Supplier C the stated quantities under the long-term fixed price supply contracts as the Company’s management determined after taking into consideration all relevant factors that it would be in the Company’s best interest not to accept those deliveries when they were due (In 2014, the Company purchased the required amounts of polysilicon from Supplier C and utilized the portion of prepayments related to 2014). As a result, because the contract has been substantially executed, the vendor claimed that certain advance payments had been forfeited. Unlike the take or pay obligation for Supplier A described in Note 18(a), if the Company fails to take the full amount of the agreed annual quantity in any calendar year, the Company does not have to pay for the remaining annual commitment, but rather only forfeits the unutilized portion of the prepayment related to that year. Further, the Company does not have the right to utilize this prepayment for deliveries in the following years. For years ended December 31, 2013, 2014 and 2015, impairment provided against the forfeited advance payments was RMB 87,134 71,266 11,002 For year ended December 31, 2015, the Company made an assessment and estimated that for the Company’s best interest, the Company would continue not to purchase from Supplier C the stated quantities in the remaining execution period of these long-term fixed price supply contracts. As a result, an additional impairment of RMB 450,784 69,589 Year ended December 31, 2013 2014 2015 RMB RMB RMB US$ Beginning balance - (87,134 ) (87,134 ) (13,451 ) Additions (87,134 ) - (522,050 ) (80,591 ) Ending balance (87,134 ) (87,134 ) (609,184 ) (94,042 ) As of December 31, 2014 and 2015, total impairment provided against prepayments to Supplier C in relation to inventory purchase commitments was RMB 87,134 13,451 609,184 94,042 277,392

Commitments and Contingencies Disclosure [Text Block]	(24) Commitments and Contingencies (a) Commitments As of December 31, 2015, commitments outstanding for the purchase of property, plant and equipment approximated RMB 1,256,106 202,448 In order to secure adequate and timely supply of polysilicon, the Company entered into a number of multi-year supply agreements from 2006 through 2011. Year ended December 31, RMB US$ 2016 218,185 33,682 2017 1,456,829 224,896 2018 1,595,406 246,288 2019 1,945,774 300,376 2020 1,945,774 300,376 Thereafter 8,983,114 1,386,753 Total 16,145,082 2,492,371 The purchase prices under the multi-year supply agreements are subject to adjustments, taking into consideration the spot market price, the cost to produce the polysilicon, among other things. The Company purchased polysilicon from Supplier B in the amount of RMB 415,075 561,487 461,515 71,246 Besides the “take or pay” arrangements, future minimum obligations under other polysilicon supply agreements with Supplier C amounted to RMB 4,261,237 657,822 732,626 701,784 248,496 38,361 522,050 In terms of the supply agreement with Supplier A, it is impractical for the Company to execute the agreement because of the events such as anti-dumping and anti-subsidy investigations into solar-grade polysilicon imported from the U.S. and South Korea launched by the Ministry of Commerce of the PRC in July 2012 that have occurred are beyond the management’s control. Therefore, based on assessment of management, no material losses or costs should be incurred for not executing the agreement. Reserve for inventory purchase commitments was provided against Supplier A for year ended December 31, 2015, please refer to note (18). (b) Contingencies From July 2009 through March 2013, the Company signed several agreements and amendments with a supplier to provide recovery service of exhausted slurry for the Company. According to the series of agreements and amendments with the supplier, the Company guaranteed a minimum annual supply volume of exhausted slurry. Starting from late 2011, due to certain quality control issues related to the supplier and substantial changes in the slurry processing market, we and this supplier had disputes over the performance of the supply contracts and payments of accounts receivable. In May 2013, the supplier informed the Company that it would like to cease the recovery service and claimed compensation. In July 2014, the Company filed litigation against this supplier for breach of contract and claimed damages against this supplier. In September 2015, the supplier also filed litigation against the Company for the default in performance of contract and claimed compensation. The court consolidated these two disputes in January 2016, in accordance with the Company’s request. While it is premature at this stage to evaluate the final outcome, the Company believes that the supplier’s claims lack merits. In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2015 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated. In October 2013, the Company received notice of an antitrust filed by Energy Conversion Devices Liquidation Trust (“ECD”), through its liquidating trustee, against the Company and two other China-based photovoltaic panel manufacturers. in the U.S. District Court of the Eastern District of Michigan. ECD alleges a wide-ranging conspiracy among the Company and other two Chinese photovoltaic panel manufacturers, their suppliers, banks and the Chinese government to destroy ECD and the U.S. solar industry by flooding the market with cheap photovoltaic panels. On October 31, 2014, the Court granted our joint motion to dismiss the case. In November 2014, the plaintiff filed a motion for reconsideration and a second motion to amend or alter the judgement and for leave to file an amended complaint, both of which were denied by the Court in September 2015. ECD has appealed to the U.S. Court of Appeals for the Sixth Circuit, and that appeal remains pending. While it is premature at this stage of the litigations to evaluate the likelihood of favorable or unfavorable outcomes, we believe that ECD’s claims lack merits. We intend to defend vigorously against those allegations. In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2015 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated. In May and June 2015, two individual plaintiffs respectively filed purported class action securities fraud lawsuits against us, our chairperson and chief executive officer, Mr. Liansheng Mao, and the Company’s director and chief executive officer, Mr. Yiyu Wang, in the U.S. District Court for the Central District of California, both alleging, among other things, that the Company made false and misleading statements and failed to disclose certain material financial information. In October 2015, the cases were consolidated and the court appointed lead plaintiffs and lead counsel. In November 2015, lead plaintiffs filed a consolidated amended complaint. The amended complaint contends that we and certain of our officers and directors made false or misleading statements between December 2, 2010 and May 15, 2015 regarding (i) the Chinese government’s Golden Sun program, which provided subsidies for solar projects in China; and (ii) the Company’s accounts receivable attributable to Chinese customers. The sole claim against the Company is for violation of Section 10(b) of the Securities Exchange Act of 1934. In December 2015, the Company filed a motion to dismiss the consolidated suit. Plaintiffs filed an opposition to the motion on January 15, 2016, and we filed a reply on January 29, 2016. The court heard oral argument on the motion on May 2. On May 10, 2016, the Court issued a written decision granting Yingli’s motion to dismiss with leave to amend. Plaintiffs have until June 24, 2016 to file an amended complaint. In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2015 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated. In October 2012, the Company received notice of an antitrust and unfair competition lawsuit filed by Solyndra, LLC (“Solyndra”, a U.S.-based solar company) against the Company and two other China-based photovoltaic panel manufacturers in the U.S. District Court of the Northern District of California. The Company filed its joint motion to dismiss all of Solyndra’s claims with the co-defendants in March 2013. On April 9, 2014, the Company received an order denying defendants’ joint motion to dismiss Solyndra’s claims. In February 2016, the Company entered into an agreement to settle these claims (“the Settlement Agreement”). According to the Settlement Agreement, i) the Company together with Yingli Green Energy Americas, Inc. (“Yingli Americas”, one subsidiaries of the Company), shall pay US$ 7.5 10 7.5 48.7 10 64.8

These technologies included the design and configuration of the Company’s PV manufacturing line, manufacturing technologies and process for high efficiency silicon solar cells and provision of innovations for continuous improvement of cell efficiencies and manufacturing cost reduction. Management estimated that the economic useful life of technical know-how by taking into consideration of the remaining life cycle of the current manufacturing technologies. Management estimated the useful life of the customer relationships based primarily on the historical experience of the Company’s customer attrition rate and estimated sales to these customers in future years. The straight-line method of amortization has been adopted as the pattern in which the economic benefit of the customer relationship are used, cannot be reliably determined. The estimated fair values of short-term and long-term supply agreements were determined based on the present values of the after-tax cost savings of the Company’s short-term and long-term supply agreements. The after-tax cost savings of the Company’s short-term and long-term supply agreements were based on the difference of price of polysilicon between the agreed purchase price per the supply contracts and the forecasted spot market price at time of the forecasted inventory acquisition. The after-tax costs savings also considered the interest impact of making the pre-payments in accordance with the supply agreements payment terms. Management estimated the useful life of the short-term and long-term supply agreements based upon the contractual delivery periods specified in each agreement. The long-term supply agreements relate to four long-term polysilicon supply agreements with delivery period commencing in 2009.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	( Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably and to generate cash flows from operations, and the ability to pursue financing arrangements, including the renewal or rollover of its bank borrowings, to support its working capital requirements and its obligations and commitments on loans and borrowings when they become due. For the year ended December 31, 2015, the Company incurred a net loss of RMB 5,898,836 910,623 As of December 31, 2015, the Company 5,939,684 916,929 7,257,335 1,120,339 1,587,675 245,095 9,124,183 1,408,531 2,405,898 371,407 300,000 46,312 1.1 163.2 700,000 108,061 accrued 1.45 224.5 that became The Company has carried out a review of its cash flow forecast for the twelve months ending December 31, 2016. In preparing the cash flow forecast, the Company’s management has considered historical cash requirements of the Company, the Company’s expected debt repayment obligations in 2016, the Company’s plan to further reduce operating costs and expenses, as well as the alternative financing plans discussed in detail below. The Company’s management also made the assumption that there will be no significant decrease of the Company’s shipments of modules and gross profit margin. Alternative Financing Plans The Company is currently exploring a variety of alternative financing plans to improve the Company’s liquidity and financial position. Debt Restructuring and Introducing Strategic Investors As of December 31, 2015, the Company had medium-term notes of RMB 2,057,000 357,000 October 13, 2015 1,400,000 May 12, 2016 300,000 May 3, 2017 The Company is also in negotiation proactively with certain investors for potential strategic investments in the Company or its major subsidiaries. Such debt restructuring and strategic investments, if successfully completed, will further increase the liquidity of the Company and improve its debt-to-equity ratio. Renewal or Rollover of Borrowings and other Financing Arrangements The Company has maintained good credit records and relationships with its lending banks and other financial institutions in China. In addition, the Company has obtained financing through other arrangements, such as sale and lease back of certain machinery and equipment and sale and repurchase of certain equity interest in its subsidiary. The Company has failed to fulfill its payment obligations under some of these arrangements in the past. As of December 31, 2015, the Company had RMB 175 million of payment obligation overdue under its agreement with a leasing company for sale and lease back of certain machinery and equipment and RMB 100 million of payment obligation overdue under its agreement with a third party for sale and repurchase of 5.50% equity interest of Hainan Yingli. As of December 31, 2015, the Company recorded the RMB 175 million and RMB 100 million of payment obligation overdue as borrowings and payables, respectively. The Company is still in negotiation with these third parties about the extension of our payment schedules under the relevant agreements. There can be no assurance, however, that such expected financing plans will be successfully completed or completed on terms acceptable to the Company. The Company ’
Consolidation, Policy [Policy Text Block]	(b) Principles of Consolidation The accompanying consolidated financial statements include the accounts of Yingli Green Energy and its subsidiaries. For consolidated subsidiaries where the Company’s ownership in the subsidiary is less than 100 The Company applies the guidance codified in Accounting Standard Codification 810, Consolidations (“ASC 810”) on accounting for VIEs and their respective subsidiaries, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns, or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor. Accordingly, the financial statements of the VIEs and VIEs’ subsidiaries are consolidated into the Company’s financial statements. In 2014, the Company signed several contracts with Yingli PV Investment Group Co., Ltd. (“Yingli PV Group”) to construct all project assets on behalf of the Company. Each project asset is owned by a special purpose entity which is owned 100 100 23 In September 2015, the Company entered into an agreement with Yingli PV Group to terminate the above-mentioned construction contracts and the Company was no longer entitled to any rights or undertook any obligations under the aforementioned contracts. As a result, the Company disposed all the project assets under the VIE structure to Yingli PV Group. Total consideration for disposal of all entities under the VIE structure was RMB 554,452 85,593 6,852 1,058 561,304 86,650 1,886,045 1,324,741 In 2015, the Company also entered into three separate agreements with three entities unrelated to the Company to transfer the Company’s 100 28,430 4,389 30,002 4,631 1,572 243 180,752 179,180
Concentration Risk Credit Risk [Policy Text Block]	(c) Significant Concentrations and Risks Revenue concentrations The Company’s business depends substantially on government incentives given to its customers. In many countries in which the Company sells its products, the market of the Company’s products would not be commercially viable on a sustainable basis without government incentives. This is largely in part caused by the cost of generating electricity from solar power currently exceeding and that is expected to continue to exceed the costs of generating electricity from conventional energy sources.

As a result, the Company’s financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures and changes in regional or worldwide economic or political conditions. Management currently expects that the Company’s operating results will, for the foreseeable future, continue to depend on the sale of PV modules to a relatively small number of customers. The Company’s relationships with such key customers have been developed over a short period of time and are generally in their preliminary stages. Any factors adversely affecting the business operations of these customers could have a material adverse effect on the Company’s business and results of operations. In 2013, 2014 and 2015, sales to the top five customers accounted for approximately 15.2 13.9 19.4 10 As of December 31, 2014 and 2015, the top five outstanding accounts receivable balances (net of provisions) accounted for approximately 27.2 27.6 10 10 Dependence on suppliers Polysilicon is the most important raw material used in the production of the Company’s PV products. To maintain competitive manufacturing operations, the Company depends on timely delivery by its suppliers of polysilicon in sufficient quantities. The Company’s failure to obtain sufficient quantities of polysilicon in a timely manner could disrupt its operations, prevent it from operating at full capacity or limit its ability to expand as planned, which will reduce the growth of its manufacturing output and revenue. In order to secure a stable supply of polysilicon and other raw materials, the Company makes prepayments to certain suppliers. Such amounts are recorded as prepayments to suppliers, prepayments to related party suppliers (included in “Amounts due from and prepayments to related parties”), and “Long-term prepayments to suppliers” in the Company’s consolidated balance sheets and amounted to RMB 1,681,562 1,212,614 187,195 December 31, 2014 2015 Location RMB RMB US$ Supplier A Singapore 212,612 224,029 34,584 Supplier B South Korea 158,613 158,613 24,486 Supplier C Germany 784,866 277,392 42,822 Total 1,156,091 660,034 101,892 The Company obtains some equipment to be used in its manufacturing process from a small number of selected equipment suppliers. In addition, some equipment has been customized based on the Company’s specifications, is not readily available from multiple vendors and would be difficult to repair or replace. If any of these suppliers were to experience financial difficulties or go out of business, the Company may have difficulties in repairing or replacing its equipment in the event of any damage to the manufacturing equipment or a breakdown of the production process. The Company’s ability to deliver products timely would suffer, which in turn could result in order cancellations and loss of revenue. A supplier’s failure to deliver the equipment in a timely manner with adequate quality and on terms acceptable to the Company could delay its capacity expansion of manufacturing facilities and otherwise disrupt its production schedule or increase its costs of production.

To limit exposure to credit risk relating to bank deposits, the Company primarily places bank deposits with large financial institutions in the PRC with acceptable credit rating. As of December 31, 2014 and 2015, the Company had cash balances at two and one PRC individual financial institutions, respectively, that held cash balances in excess of 10% of the Company’s total cash balances. These bank deposits collectively accounted for approximately 37.2 34.4
Use of Estimates, Policy [Policy Text Block]	(d) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities as well as with respect to the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the fair values of assets acquired and liabilities assumed in business acquisitions, the useful lives of property, plant and equipment and intangibles with definite lives, recoverability of the carrying values of property, plant and equipment, and intangible assets, the fair value of share-based payments, the collectability of accounts receivable, the realizability of inventories, prepayments and deferred income tax assets, the fair values of financial and equity instruments, the accruals for warranty obligations and loss contingency, and provision for inventory purchase commitments. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	(e) Foreign Currency The Company’s reporting currency is the Renminbi (“RMB”). Assets and liabilities of foreign companies whose functional currency is not RMB are translated into RMB using the exchange rate on the balance sheet date. Revenues and expenses are translated at average rates prevailing during the year. Gains and losses resulting from the translation of financial statements of foreign companies are recorded as a separate component of accumulated other comprehensive income within shareholders’ equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. The resulting exchange differences are recorded in “foreign currency exchange gains (losses)” in the Consolidated Statements of comprehensive Loss. Transaction gains and losses resulting from intercompany foreign currency transactions that are of a long-term investment nature are treated in the same manner as translation adjustments and therefore excluded from the determination of net loss. RMB is not freely convertible into foreign currencies. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (“PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC. For the convenience of readers, certain 2015 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.4778
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	( Cash, Cash equivalents and Restricted Cash Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less. Restricted cash of RMB 1,332,404 346,926 53,556
Receivables, Policy [Policy Text Block]	( Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance for doubtful accounts is based on a review of specifically identified accounts and aging data. Judgments are made with respect to the collectability of accounts receivable balances based on historical collection experience, customer specific facts and current economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Sale of Accounts Receivable In 2013 and 2014, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyers were responsible for servicing the receivables. The accounts receivables were determined to be legally isolated from the Company and its creditors, even in the event of bankruptcy or other receivership and the Company had surrendered control over the transferred receivables. As a result, the accounts receivables were considered sold and were therefore derecognized. The Company received proceeds from the sale of accounts receivable of RMB 677,795 188,117 11,840 8,885
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost or market. Cost is determined by using the weighted-average cost method. Cost of work-in-progress and finished goods are comprised of direct materials, direct labour, and an allocation of related manufacturing overhead based on normal operating capacity. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. Certain factors could impact the realizable value of inventory, so the Company continually evaluates the recoverability based on assumptions about customer demand and market conditions. The evaluation may take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer concentrations, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that could negatively impact the Group’s gross margin and operating results. If actual market conditions are more favorable, the Company may have higher gross margin when products that have been previously written down are eventually sold.
Prepayments To Suppliers [Policy Text Block]	( Prepayments to Suppliers Advance payments for the future delivery of raw materials are made based on written purchase orders detailing product, quantity, pricing and are classified as “prepayments to suppliers” in the consolidated balance sheets. The Company’s supply contracts grant the Company the right to inspect products prior to acceptance. The amount in the balance of the “prepayments to suppliers” is and reclassified to “inventories” when inventory is received and passes quality inspection. Such reclassifications of RMB 245,906 340,007 318,132 49,111 23,338 144,803 721,651 555,520 85,758 For the years ended December 31, 2013, 2014 and 2015, provisions of RMB 87,134 522,050 80,591
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Long-lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the asset, taking into consideration any estimated residual value, using the straight-line method. When items are retired or otherwise disposed of, income is charged or credited for the difference between net book value and proceeds received thereon. Ordinary maintenance and repairs are charged to expense as incurred, and replacements and betterments are capitalized. Buildings 30 Machinery and equipment 4 25 Furniture and fixtures 3 5 Motor vehicles 8 10 Depreciation of property, plant and equipment attributable to manufacturing activities is capitalized as part of the cost of inventory production, and expensed to cost of revenues when the inventory is sold. Cost incurred in the construction of new facilities, including progress payments and deposits, interest and other costs relating to the construction, are capitalized and transferred out of construction in progress and into their respective asset categories when the assets are ready for their intended use, at which time depreciation commences. Leases Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Other leases are accounted for as capital leases. Payments made under operating leases, net of any incentives received by the Company from the leasing company, are charged to the consolidated statements of comprehensive loss on a straight-line basis over the lease periods. Leases that qualify as capital leases are recorded at the lower of the fair value of the asset or the present value of the future minimum lease payments over the lease term generally using the Company’s incremental borrowing rate. Assets leased under capital leases are included in property, plant and equipment and generally are depreciated over the lease term. Lease payments under capital leases are recognized as a reduction of the capital lease obligation and interest expense. For a sale-leaseback transaction, an analysis is performed to determine if the Company can record a sale and remove the assets from the balance sheet and recognize the lease; and if so, to determine whether to record the lease as either an operating or capital lease. If the Company has continued involvement beyond a normal lease, the lease is accounted for as a capital lease transaction and the assets and related financing obligation are recognized on the balance sheet. The Company’s assets under the capital lease transaction were derecognized upon sale at the net book value and rebooked at the financed amount; and the differences between the net book value derecognized and the rebooked financed amount of the assets were deferred and amortized over the lease term. Accordingly, the asset is depreciated over its estimated useful life in accordance with the Company’s policy. When the assets transaction does not qualify as a sale-leaseback transaction, it will be treated as a financing transaction. If the sale-leaseback transactions involve asset other than real estate, those are evaluated to determine whether they are considered integral with real estate, in which case the sale-leaseback rules related to real estate are applied. Refer to note (16) to the consolidated financial statement. Project assets Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the sale of the solar power project. These costs include modules, installation and other development costs. If a project is completed and begins commercial operation prior to entering into a sales agreement, which is at the point when the solar power plant is connected to grids and begins to generate electricity, costs capitalized in the construction of solar power plants under development will be transferred to solar power plants upon completion and when they are ready for its intended use. Any income generated by such project is accounted for as revenue. Depreciation is provided over the estimated useful lives of the projects assets ( 20-25 years), taking into consideration any estimated residual value, using the straight-line method, and expensed to cost of revenues. As of December 31, 2015, project assets with carrying value of RMB 235,229 36,313 485,057 74,880 For the years ended December 31, 2013, 2014 and 2015, revenue related to the projects assets from power generation were nil, RMB 2,015 30,836 4,760 2,365, 37,855 5,844 . Other Intangible Assets Trademarks that have an indefinite useful life are not amortized, but instead are tested for impairment at least annually. Intangible assets, other than trademarks, are amortized on a straight-line basis over the estimated useful lives of the respective assets. 5.5 6 Customer relationships 5.5 6 Order backlog 1 1.5 Short-term supply agreements 0.5 Impairment of Long-Lived Assets Long-lived assets, such as property, plant, and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Intangible assets that are not subject to amortization are tested annually for impairment at December 31, and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. For intangible assets that are not subject to amortization, an impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. For the years ended December 31, 2013 and 2014, no impairment loss arose on long-lived assets. For the year ended December 31, 2015, a total impairment loss against property, plant and equipment amounted to RMB 3,804,116 587,254 Government grant Government grants are recorded in the balance sheet when they are received and that the Company will comply with the conditions attaching to them. Government grants, which are obtained by the Company for the purposes of purchase, construction or acquisition of the long-term assets, will be recorded as “Deferred other income” and included in “Deferred other income” in the Consolidated Balance Sheets and are depreciated or amortized evenly over the useful lives of the related assets. For the years ended December 31, 2013, 2014 and 2015, the Company received government grants of RMB 350,028 80,849 74,581 11,513 53,419 49,557 56,935 8,789 Government grants other than those related to assets, will be recorded as “Deferred other income” and recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss in the period in which the related expenses are recognized if the grants are intended to compensate for future expenses or losses, and otherwise recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss for the current period if the grants are used to compensate for expenses or losses that have been incurred.
Land and Land Use Rights [Policy Text Block]	Land and Land Use Rights Land represents the cost of land acquired outside the PRC with indefinite useful life. Land use rights represent the cost of rights to use land in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the respective periods of the rights of 45 50
Equity Method Investments, Policy [Policy Text Block]	(l) Equity Investments Investments in entities where the Company does not have a controlling financial interest, but has the ability to exercise significant influence over the operating and financial policies of the investees, are accounted for using equity method accounting. Under the equity method accounting, the Company’s share of the investees’ results of operations is included in “Equity in Income/Loss of Affiliates” in the Company’s Consolidated Statements of Comprehensive Loss. Equity investments are accounted for under cost method when the Company does not have the ability to exercise significant influence over the operating and financial policies of the investees. Under the cost method of accounting, the Company records an investment in the equity of an investee as cost, and recognizes as income dividends received that are distributed from net accumulated earnings of the investee since the date of acquisition. The Company does not have available-for-sale investment. In case the Company sells modules to its equity method investee, the profit derived from the transaction is eliminated to the extent of the Company’s shares in that investee, and the income is credited against “Investments in affiliated companies” in the Consolidated Balance Sheets and deferred until the project assets are ultimately sold to external customers. The Company recognizes a loss when there is a loss in value of an equity investment which is other than a temporary decline. The process of assessing and determining whether an impairment on a particular equity investment is other than temporary requires a significant amount of judgment. To determine whether an impairment is other-than-temporary, management considers whether the Company has the ability and intent to hold the investment until recovery and whether evidence indicating the carrying value of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the decline in value, any change in value subsequent to year end, and forecasted performance of the investee.
Statutory Reserves [Policy Text Block]	( Statutory Reserves In accordance with the relevant laws and regulations of the PRC, PRC enterprises are required to transfer 10 50 499,383 500,164 77,212
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments and Hedging Activities The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are either offset through earnings against the change in fair value of the designated hedged item attributable to the risk being hedged or recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings. The Company enters into derivative contracts that it intends to designate as a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For all hedging relationships, the Company formally documents the hedging relationship and its risk management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company also formally assesses, both at the inception of the hedging relationship and on an ongoing basis, whether the derivatives that are used in hedging relationships are highly effective in offsetting changes in cash flows of hedged transactions. For derivative instruments that are designated and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The maximum term over which the Company is hedging exposures to the variability of cash flows for forecasted transaction is 12 months. The Company discontinues hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedged risk, the derivative expires or is sold, terminated, or exercised, the cash flow hedge is designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in in the Consolidated Statement of Comprehensive loss. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in the Consolidated Statement of Comprehensive loss gains and losses that were accumulated in other comprehensive income related to the hedging relationship.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-based Payment The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the costs over the period the employee is required to provide service in exchange for the award, which generally is the vesting period. The Company estimates grant date fair value using the Black Scholes-Merton option pricing model. The Company recognizes compensation cost for an award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, net of estimated forfeitures, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant date value of such award that is vested at that date. Forfeiture rates are estimated based on historical and future expectations of employee turnover rates. The Company applies the fair value method for equity instrument issued to non-employee under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 505-50 , Equity-based Payments to Non-employees
Revenue Recognition, Policy [Policy Text Block]	(p) Revenue Recognition Revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, the fee is fixed or determinable and collectability is reasonably assured. These criteria are determined in relation to the sale of the Company’s products or services as follows: For all sales, the Company requires a contract or purchase order which specified pricing, quantity and product specifications. For sales of PV modules from PRC to foreign customers, delivery of the products occurs at the point the product is delivered to the named port of shipment, which is when the risks and rewards of ownership are transferred to the customer. For sales of PV modules to domestic customers in PRC or by foreign subsidiaries, delivery of the product occurs at the point the product is received by the customer, which is when the risks and rewards of ownership have been transferred. Sales of PV systems consist of the delivery, assembly and installation of PV modules, related power electronics and other components. The Company considers the PV system to be delivered, and the risks and rewards of ownership transferred, when installation of all components is complete and customer acceptance is received. Customer acceptance is evidenced by a signed project acceptance document. The assembly and installation of PV systems is short, generally lasting between 1 3 The Company recognizes revenue for solar power station constructed for commercial customers according to ASC 605-35, Revenue Recognition—Construction-Type and Production Type Contracts 20,713 24,912 3,846 Starting in 2015, the Company provides PV cell / PV module processing services to customers. Under certain of these processing service arrangements, the Company purchases raw materials from a customer and agrees to sell a specified quantity of PV cells / PV modules produced from such materials back to the same customer. The Company recognizes revenue from these processing transactions on a net basis, that is, the revenue is recorded based on the amount received for PV cells / PV modules sold less the amount paid for the raw materials purchased from the customer. For sales of raw materials, PV cells and wafers, delivery occurs at the point the product is delivered to the customer, which is when the risks and rewards of ownership have been transferred. Delivery is evidenced by a signed customer acceptance form. Shipping and handling fees billed to customers are recorded as revenues, and the related shipping or delivery costs of RMB 405,839 311,356 239,519 36,975 Advance payments received from customers for future sale of inventory are recognized as advances from customers in the consolidated balance sheets. Advances from customers are recognized as revenues when the conditions for revenue recognition described above have been satisfied. Advances from customers have been recognized as a current liability because the amount at each balance sheet date is expected to be recognized as revenue within twelve months. In 2010 – 2012, a government subsidy project called “Golden Sun” program was proposed by the Ministry of Finance of PRC(“MOF”), to support and encourage PV stations installation. PV station owners could apply for a “Golden Sun” subsidy for the PV station to be constructed and solar companies may bid for the project as target vendors who would be authorized to supply PV modules to qualified PV station. According to detail implementation guidance, the government will give subsidy to each qualified PV station owners and the PV station owners’ obligation was to make sure that qualified PV stations would be successfully connected to national electric grid and pass the acceptance check by authorized supervisor appointed by the government (“government acceptance check”) within the period required by the government. Instead of paying full subsidy to PV station owners directly, the government should pay partial subsidy to qualified suppliers on behalf of PV station owners as advance before the commencement of construction of PV stations. Yingli China was a successful bidder as the qualified supplier for “Golden Sun” program. For year ended December 31, 2015, as agreed with local government of Hebei Province, due to that certain PV stations didn’t start construction and passed the government acceptance check within the required period, subsidy with RMB 286,277 44,194 The sales of the subsidiaries in the PRC are subject to Value added tax (“VAT”) at a general rate at 17

Standard Product Warranty, Policy [Policy Text Block]	(s) Warranty Cost Before September 30, 2011, the Company’s multicrystalline PV modules are typically sold with a two or five-year limited warranty for defects in materials and workmanship, and a 10 25 90 80 Effective October 1, 2011, the Company implemented a new and improved warranty terms for multicrystalline PV module that guarantees 91.2 80.7 10 25 98.0 92.0 82.0 10 25 The Company performs industry-standard testing to test the quality, durability and safety of the Company’s products. As a result of such tests, management believes the quality, durability and safety of its products are within industry norms. Management’s estimate of the amount of its warranty obligation is based on the results of these tests, consideration given to the warranty accrual practice of other companies in the same industry and the Company’s expected failure rate and future costs to service failed products. The Company’s warranty obligation will be affected by its estimated product failure rates, the costs to repair or replace failed products and potential service and delivery costs incurred in correcting a product failure. Consequently, the Company accrues the equivalent of 1 Actual warranty costs are charged against the accrued warranty liability. Warranty expense is recorded as selling expense. Changes in the carrying amount of accrued warranty liability are as follows: Year Ended December 31, 2013 2014 2015 RMB RMB RMB US$ Beginning balance 555,357 666,946 748,428 115,537 Warranty provision for the current year 125,900 120,780 84,520 13,048 Warranty costs incurred or claimed (14,311) (39,298) (40,809) (6,300) Total accrued warranty cost 666,946 748,428 792,139 122,285 Less: accrued warranty cost, current portion 40,632 40,903 38,869 6,000 Accrued warranty cost, excluding current portion 626,314 707,525 753,270 116,285
Purchase Commitment [Policy Text Block]	(t) Firm Purchase Commitment The Company entered into several long-term fixed price contracts to purchase polysilicon to ensure an adequate supply of polysilicon to operate its plants. These contracts represent firm purchase commitments which are evaluated for potential market value losses.

Income Tax, Policy [Policy Text Block]	(u) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and any tax loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or tax laws is recognized in the consolidated statements of comprehensive loss in the period the change in tax rates or tax laws is enacted. A valuation allowance is provided to reduce the amount of deferred income tax assets if it is considered more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company recognizes in the consolidated financial statements the impact of an unrecognized tax benefit, if the position is not more likely than not of being sustained upon examination, based on the technical merits of the position. Recognized income tax benefits are measured at the largest amount that is greater than 50
Commitments and Contingencies, Policy [Policy Text Block]	(v) Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. The Company is exposed to risks associated with liability claims in the event that the use of the PV products the Company sells results in injury. The Company does not maintain any third-party liability insurance coverage other than limited product liability insurance or any insurance coverage for business interruption. As a result, the Company may have to pay for financial and other losses, damages and liabilities, including, those in connection with or resulting from third-party product liability claims and those caused by natural disasters and other events beyond the Company’s control, out of its own funds, which could have a material adverse effect on its financial conditions and results of operations.
Segment Reporting, Policy [Policy Text Block]	Segment Reporting The Company uses the management approach in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions, allocating resources and assessing performance as the source for determining the Company’s reportable segments. Management has determined that the Company has only one operating segment.
Earnings Per Share, Policy [Policy Text Block]	(x) Earnings Per Share In accordance with FASB ASC Topic 260, Earnings Per Share, basic earnings per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the year. Ordinary equivalent shares consist of the ordinary shares issuable upon the exercise of outstanding share options (using the treasury stock method). Potential dilutive securities are not included in the calculation of dilutive earnings per share if the impact is anti-dilutive.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. See note (8) to the consolidated financial statements.
Reclassification Of Comparative Figures [Policy Text Block]	Reclassification of comparative figures Certain comparative figures have been reclassified to conform to the current year presentation.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will require the Company to separate performance obligations within a contract, determine total transaction costs, and ultimately allocate the transaction costs across the established performance obligations. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers" (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. As a result, ASU 2014-09 will become effective for the Company beginning in fiscal 2018 under either full or modified retrospective adoption, with early adoption permitted as of the original effective date of ASU 2014-09. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. In February 2015, the FASB issued the ASU 2015-02, "Amendments to the Consolidation Analysis". The objective of issuing the amendments in this Update is to change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in this Update are an improvement to current US GAAP because they simplify the Codification and reduce the number of consolidation models through the elimination of the indefinite deferral of Statement 167 and because they place more emphasis on risk of loss when determining a controlling financial interest. The amendments in this Update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. A reporting entity may apply the amendments in this Update using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. A reporting entity also may apply the amendments retrospectively. The Company plans to apply this standard beginning in 2016 and does not expect this guidance to have a material impact on the Company’s consolidated financial statements. In April 2015, the FASB issued the ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), which changes the presentation of debt issuance costs in financial statements. Under ASU 2015-03, an entity will present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. In August 2015, the FASB issued the ASU No. 2015-15—Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements ("ASU 2015-15"), which incorporates the SEC staff's announcement that clarifies the exclusion of line-of-credit arrangements from the scope of ASU 2015-03. The ASU clarifies that debt issuance costs related to line-of-credit arrangements can be deferred and presented as an asset that is subsequently amortized over the time of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is effective retrospectively for interim and annual periods beginning after December 15, 2015. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. As of December 31, 2015, the total balance of deferred debt issuance cost included in “Prepaid expenses and other current assets” was RMB 1,595 246 In September 2015, the FASB issued the ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement for acquirers in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts that would have been recorded in previous periods if the accounting had been completed at the acquisition date. This update is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. In November 2015, the FASB issued the ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, to simplify the presentation of deferred income taxes. The amendments in this Update require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this Update apply to all entities that present a classified statement of financial position. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this Update. For public business entities, the amendments in this Update are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. The amendments in this Update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. If an entity applies the guidance prospectively, the entity should disclose in the first interim and first annual period of change, the nature of and reason for the change in accounting principle and a statement that prior periods were not retrospectively adjusted. If an entity applies the guidance retrospectively, the entity should disclose in the first interim and first annual period of change the nature of and reason for the change in accounting principle and quantitative information about the effects of the accounting change on prior periods. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. As of December 31, 2015, total balances of current deferred tax assets and current deferred tax liabilities was nil and RMB 4,093 632 In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. This accounting standard retains the current accounting for classifying and measuring investments in debt securities and loans, but requires equity investments to be measured at fair value with subsequent changes recognized in net income, except for those accounted for under the equity method or requiring consolidation. This guidance also changes the accounting for investments without a readily determinable fair value and that do not qualify for the practical expedient to estimate fair value. A policy election can be made for these investments whereby estimated fair value may be measured at cost and adjusted in subsequent periods for any impairment or changes in observable prices of identical or similar investments. This revised guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. This accounting standard requires lessees to recognize assets and liabilities related to lease arrangements longer than 12 months on the balance sheet. This standard also requires additional disclosures by lessees and contains targeted changes to accounting by lessors. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, Contingent Put and Call Options in Debt Instruments. The amendments in this Update apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The Amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts, which is one of the criteria for bifurcating an embedded derivative. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. The amendments are an improvement to GAAP because they eliminate diversity in practice in assessing embedded contingent call (put) options in debt instruments. For public companies, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. An entity should apply the amendments in this Update on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Simplifying the Transition to the Equity Method of Accounting. The amendments in this Update eliminate the requirement that when an investment qualified for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previous held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increase in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is currently assessing the potential significant effects of these changes on the Company's consolidated financial statements.

[1]	Prior to FY 2014, Baoding Tianwei Baobian Electric Co., Ltd. (“Tianwei Baobian”), a third party, held 25.99% equity interest in Tianwei Yingli. In May 2014, the Company, Baoding Tianwei Group Co., Ltd.(“ Tianwei Group”), and Tianwei Baobian entered into a new joint venture contract and Tianwei Baobian transferred 7% equity interest in Tianwei Yingli to Tianwei Group. Under a Sino-foreign equity joint venture company contract with Tianwei Baobian and Tianwei Group, it provides that Tianwei Baobian and/or Tianwei Group will have a right to swap the shares of the Company with the all but not part shares of the non-controlling interest in Tianwei Yingli. The terms of the swap will be discussed separately at the time of the swap. The Company does not account for such share swap until a separate agreement is signed that clearly states the terms and basis of the share swap between the non-controlling shareholders and the Company. Tianwei Baobian and/or Tianwei Group may exercise this subscription right after certain conditions are satisfied following the completion of the Company’s IPO. Tianwei Baobian and/or Tianwei Group’s subscription rights to subscribe for newly issued ordinary shares of the Company in exchange for all but not part of Tianwei Baobian and/or Tianwei Group’s equity interest in Tianwei Yingli did not have an effect on earnings per share as these rights are contingent upon Tianwei Baobian and/or Tianwei Group obtaining all necessary approvals from relevant PRC government authorities for acquiring our ordinary shares in the future. As of December 31, 2014, Tianwei Baobian and/or Tianwei Group haven’t exercised this subscription right.
