| 3. Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
| Dec. 31, 2019 |
| Accounting Policies [Abstract] | |
| Basis of Presentation | (a) Basis of Presentation The accompanying consolidated financial
statements of the Group are prepared in conformity 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 Group’s ability to operate profitably, to generate cash flows from operations,
and to pursue financing arrangements to support its working capital requirements. |
| Principles of Consolidation | (b) Principles of Consolidation The consolidated financial statements
include the financial statements of the Company, and its subsidiaries. All material inter-company transactions and balances have
been eliminated upon consolidation. For consolidated subsidiaries where the Company’s ownership in the subsidiary is less
than 100%, the equity interest not held by the Group is shown as noncontrolling interests. The Company accounts for investments
over which it has significant influence but not a controlling financial interest using the equity method of accounting. The Company
deconsolidates a subsidiary when the Company ceases to have a controlling financial interest in the subsidiary. When control is
lost, the parent-subsidiary relationship no longer exists and the parent derecognizes the assets and liabilities of the subsidiary. |
| Use of Estimates | (c) Use of Estimates The preparation of the financial
statements in conformity with U.S. GAAP requires the Group to make estimates and assumptions that affect reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well
as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Significant accounting estimates reflected in the Company’s consolidated financial statements include the allowance made
for doubtful accounts receivable and other receivable, inventory write-downs, the estimated useful lives of long-lived assets,
the impairment of goodwill, long-lived assets and project assets, fair value of derivative liability, valuation allowance of deferred
tax assets, accrued warranty expenses, the grant-date fair value of share-based compensation awards and related forfeiture rates,
the lease discount rate, and fair value of financial instruments and assumptions related to the consolidation of entities in which
the Company holds variable interests. Changes in facts and circumstances may result in revised estimates. The current economic
environment has increased the degree of uncertainty inherent in those estimates and assumptions. |
| Foreign Currency Translation and Foreign Currency Risk | (d) Foreign Currency Translation and Foreign Currency Risk The functional currency of the Company
and subsidiaries located in the United States is the United States dollar (“US$” or “$”). The functional
currency of the Company’s subsidiaries located in the PRC, Europe, United Kingdom, Japan and Australia are Renminbi (“RMB”),
EURO (“EUR”), British Pounds(“GBP”), Japanese Yen (“JPY”) and Australia Dollar (“AUD”),
respectively. Transactions denominated in foreign currencies are re-measured into the functional currency at the rates of exchange
prevailing when the transactions occur. Monetary assets and liabilities denominated in foreign currencies are re-measured into
the functional currency at rates of exchange in effect at the balance sheet dates. Exchange gains and losses are included in the
consolidated statements of operations. The Group’s reporting currency
is the US$. Assets and liabilities of subsidiaries, whose functional currency is not the US$, are translated into US$ using exchange
rates in effect at each period end, and revenues and expenses are translated into US$ at average rates prevailing during the year,
and equity is translated at historical exchange rates, except for the change in retained earnings during the year which is the
result of the income or loss. Gains and losses resulting from the translations of the financial statements of these subsidiaries
into US$ are recognized as other comprehensive income or loss in the consolidated statement of comprehensive loss. |
| Fair Value of Financial Instruments | (e) Fair Value of Financial Instruments The Group estimates fair value of
financial assets and liabilities as the price that would be received from the sale of an asset or paid to transfer a liability
(an exit price) on the measurement date in an orderly transaction between market participants. The fair value measurement guidance
establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value.
Level 1 — Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.
Level 2 — Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.
Level 3 — Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use to price an asset or liability. The Group uses quoted market prices
to determine the fair value when available. If quoted market prices are not available, the Group measures fair value using valuation
techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and
currency rates. |
| Business Combination | (f) Business Combination Business combinations are recorded
using the acquisition method of accounting and, accordingly, the acquired assets and liabilities are recorded at their fair market
value at the date of acquisition. Any excess of acquisition cost over the fair value of the acquired assets and liabilities, including
identifiable intangible assets, is recorded as goodwill. The Company charges acquisition related costs that are not part of the
purchase price consideration to general and administrative expenses as they are incurred. Those costs typically include transaction
and integration costs, such as legal, accounting, and other professional fees. The Company adopted Accounting Standard
Update (“ASU”) 2017-01 “Business Combination (Topic 805): Clarifying the Definition of a Business” on January
1, 2018 and applied the new definition of a business prospectively for acquisitions made subsequent to December 31, 2017. Upon
the adoption of ASU 2017-01, a new screen test is introduced to evaluate whether a transaction should be accounted for as an acquisition
and/or disposal of a business versus assets. In order for a purchase to be considered an acquisition of a business, and receive
business combination accounting treatment, the set of transferred assets and activities must include, at a minimum, an input and
a substantive process that together significantly contribute to the ability to create outputs. If substantially all of the fair
value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then
the set of transferred assets and activities is not a business. The adoption of this standard requires future purchases to be evaluated
under the new framework. |
| Asset Acquisition | (g) Asset Acquisition When the Company acquires other
entities, if the assets acquired and liabilities assumed do not constitute a business, the transaction is accounted for as an asset
acquisition. Assets are recognized based on the cost, which generally includes the transaction costs of the asset acquisition,
and no gain or loss is recognized unless the fair value of noncash assets given as consideration differs from the assets’
carrying amounts on the Company’s books. If the consideration given is not in the form of cash (that is, in the form of noncash
assets, liabilities incurred, or equity interest issued), measurement is based on either the cost to the acquiring entity or the
fair value of the assets (or net assets) acquired, whichever is more clearly evident and, thus, more reliably measureable. The
cost of a group of assets acquired in an asset acquisition is allocated to the individual assets acquired or liabilities assumed
based on their relative fair value and does not give risk to goodwill. |
| Cash and Cash Equivalents | (h) Cash and Cash Equivalents Cash and cash equivalents include
cash on hand, cash accounts, interest bearing savings accounts and all highly liquid investments with original maturities of three
months or less, and which are unrestricted as to withdrawal and use. There were no cash equivalents as of December 31, 2019 and
2018. |
| Restricted Cash | (i) Restricted Cash Restricted cash represent bank deposits
with designated use, which cannot be withdraw without certain approval or notice. Restricted cash, which matures twelve months
after the balance sheet date, is classified as noncurrent assets in the consolidated balance sheets. At December 31, 2019 and 2018, the
Group had restricted bank deposits of $239 and $458, respectively. The balance as of December 31, 2019 and 2018 mainly represented
the restricted bank deposits in the bank account established for the sole purpose of paying the obligations and making other
payments related to the project assets development in Hawaii of SPI Solar Inc., a subsidiary of the Group. |
| Accounts Receivable, net | (j) Accounts Receivable, net The Group grants open credit terms
to credit-worthy customers. Accounts receivable are primarily related to the Group's sales of pre-development solar projects and
sales of PV components. For pre-development sales contracts, the payment is typically due in installments over the contract term,
which are both before and after the performance by the Company. Payment for sales of PV components and electricity revenue with
power purchase agreements (“PPAs”) are typically due in full within 30 to 90 days of shipping of the products or the
start of the contract term. The Group maintains allowances for
doubtful accounts. The Group regularly monitors and assesses the risk of not collecting amounts owed by customers. This evaluation
is based upon a variety of factors, including an analysis of amounts current and past due along with relevant history and facts
particular to the customer. The Group does not have any off-balance-sheet credit exposure related to its customers. Contractually,
the Group may charge interest for extended payment terms and require collateral. |
| Notes Receivable | (k) Notes Receivable Notes receivable was a 12-year interest-bearing
promissory note issued by an EPC customer in 2015. The promissory note carries interests at 6% per annum and is settled by pre-determined
installments. Installment payments that fall due within 12 months and over 12 months after the balance sheet date are classified
as current assets and noncurrent assets respectively on the consolidated balance sheet. Notes receivable was fully collected during
the year ended December 31, 2019. As of December 31, 2018, no allowance was made against the notes receivable. |
| Inventories, net | (l) Inventories, net Inventories are carried at the lower
of cost or net realizable value, determined by the weighted average cost method. Provisions are made for obsolete or slow-moving
inventories based on management estimates. Inventories are written down based on the difference between the cost of inventories
and the net realizable value based upon estimates about future demand from customers, specific customer requirements on certain
projects and other factors. Inventory provision charges establish a new cost basis for inventory that subsequently cannot be marked
up based on changes in underlying facts and circumstances. |
| Project Assets, net | (m) Project Assets, net The Group acquires or constructs
PV solar power systems (“solar system”) that are (i) held for development and sale or (ii) held for the Group’s
own use to generate income or return from the use of the solar systems. Solar systems are classified as either held for development
and sale within “project assets” or as held for use within “property, plant and equipment” based on the
Group’s intended use of solar systems. The Group determines the intended use of the solar systems upon acquisition or commencement
of project construction. Classification of the solar systems
affects the accounting and presentation in the consolidated financial statements. Transactions related to the solar systems held
for development and sale within “project assets” are classified as operating activities in the consolidated statements
of cash flows and reported as sales and costs of goods sold in the consolidated statements of operations upon the sale of the solar
systems and fulfillment of the relevant recognition criteria. Incidental electricity income generated from the solar systems held
for development and sale prior to the sale of the projects is recorded in other operating income in the consolidated statement
of operations. The solar systems held for use within “property, plant and equipment”, are used by the Group in its
operations to generate income or a return from the use of the assets. Income generated from the solar systems held for use are
included in net sales in the consolidated statement of operations. The costs to construct solar systems intended to be held for
own use are capitalized and reported within property, plant and equipment on the consolidated balance sheets and are presented
as cash outflows from investing activities in the consolidated statements of cash flows. The proceeds from disposal of solar systems
classified as held for own use are presented as cash inflows from investing activities within the consolidated statements of cash
flows. A net gain or loss upon the disposal of solar systems classified as held for own use is reported in other operating income
or expense in the consolidated statement of operation. Solar systems costs consist primarily
of capitalizable costs for items such as permits and licenses, acquired land or land use rights, and work-in-process. Work-in-process
includes materials and modules, construction, installation and labor, capitalized interests and other capitalizable costs incurred
to construct the PV solar power systems. The solar systems held for development
and sale, named as “project assets”, are reported as current assets on the consolidated balance sheets when upon completion
of the construction of the solar systems, the Group initiates a plan to actively market the project assets for immediate sale in
their present condition to potential third party buyers subject to terms that are usual and customary for sales of these types
assets and it is probable that the project assets will be sold within one year. Otherwise, the project assets are reported as noncurrent
assets. No depreciation expense is recognized while the project assets are under construction or classified as held for sale. For solar systems held for development
and sale, named as “project assets”, the Group considers a project commercially viable if it is anticipated to be sold
for a profit once it is either fully developed or fully constructed. The Group also considers a partially developed or partially
constructed project commercially viable if the anticipated selling price is higher than the carrying value of the related project
assets plus the estimated cost to completion. The Group considers a number of factors, including changes in environmental, ecological,
permitting, market pricing or regulatory conditions that affect the project. Such changes may cause the cost of the project to
increase or the selling price of the project to decrease. The Group records an impairment loss of the project asset to the extent
the carrying value exceed its estimated recoverable amount. The recoverable amount is estimated based on the anticipated sales
proceeds reduced by estimated cost to complete such sales. |
| Property, Plant and Equipment, net | (n) Property, Plant
and Equipment, net The Group accounts for its property,
plant and equipment at cost, less accumulated depreciation. Cost includes the prices paid to acquire or construct the assets, interest
capitalized during the construction period and any expenditure that substantially extends the useful life of an existing asset.
The Group expenses repair and maintenance costs when they are incurred. Depreciation is recorded on the straight-line method based
on the estimated useful lives of the assets as follows:
Plant and machinery 5 or 6.67 years
Furniture, fixtures and equipment 3 or 5 years
Computers 3 or 5 years
Automobile 3 or 5 years
Bitcoin mining equipment 3 years
Leasehold improvements The shorter of the estimated life or the lease term
PV solar system 17, 20, 25 or 27 years |
| Intangible Assets Other Than Goodwill | (o) Intangible Assets other than Goodwill Intangible assets consist of customer
relationships and patents. Amortization is recorded on the straight-line method based on the estimated useful lives of the assets. |
| Impairment of Long-lived Assets | (p) Impairment of Long-lived Assets The Group’s long-lived assets
include property, plant and equipment, project assets and other intangible assets with finite lives. The Group evaluates long-lived
assets 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 Group first compare undiscounted
cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount 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 amount 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. Any impairment write-downs would
be treated as permanent reductions in the carrying amounts of the assets and a charge to operations would be recognized. |
| Bitcoins | (q) Bitcoins Bitcoins are awarded to the Company
through its mining activities which are accounted for in connection with the Company’s revenue recognition policy. Bitcoins held are accounted for
as intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life is not amortized but assessed
for impairment annually, or more frequently, when events or changes in circumstances occur indicating that it is more likely than
not that the indefinite-lived asset is impaired. Impairment exists when the carrying amount exceeds its fair value, which is measured
using the quoted price of the bitcoins at the time its fair value is being measured. In testing for impairment, the Company has
the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists.
If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary.
If the Company concludes otherwise, it is required to perform a quantitative impairment test. To the extent an impairment loss
is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted.
The balance of bitcoins was nil as of December 31, 2019 and 2018. Bitcoins awarded to the Company
through its mining activities are included within operating activities on the accompanying consolidated statements of cash flows.
The sales of bitcoins are included within investing activities in the accompanying consolidated statements of cash flows and any
realized gains or losses from such sales are included in other income (expense) in the consolidated statements of operations. The
Company accounts for its gains or losses in accordance with the first in first out (FIFO) method of accounting. |
| Goodwill | (r) Goodwill Goodwill represents the excess of
the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed
of the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries. Goodwill is not amortized
but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might
be impaired. The Company has an option to first assess qualitative factors to determine whether it is necessary to perform the
two-step quantitative goodwill impairment test. In the qualitative assessment, the Company considers primary factors such as industry
and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations.
Based on the qualitative assessment, if it is more likely than not that the fair value of each reporting unit is less than the
carrying amount, the quantitative impairment test is performed. In performing the two-step quantitative
impairment test, the first step compares the fair values of each reporting unit to its carrying amount, including goodwill. If
the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step
will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair
value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined
in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first
step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned
to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for the purposes
of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application
of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning
assets, liabilities and goodwill to reporting units, and determining the fair value of each reporting unit. |
| Product Warranties | (s) Product Warranties The Group offers the industry standard
warranty up to 25 years for PV modules and industry standard warranty for five to ten years on inverter and balance of system components.
Due to the warranty period, the Group bears the risk of extensive warranty claims long after products have been shipped and revenues
have been recognized. The Group provides a limited warranty to the original purchasers of its solar modules, inverters and cables
for trading business for one to five years, in relation to defects in materials and workmanship. For the Group’s cable, wire
and mechanical assemblies business, historically the related warranty claims have not been material. For the Group’s solar
PV business, the greatest warranty exposure is in the form of product replacement. During the quarter ended September
30, 2007 and continuing through the fourth quarter of 2010, the Group installed own manufactured solar panels and accrued warranty
based on the Group’s own historical data. Since 2011, due to the absence of historical material warranty claims and identical
warranty terms, the Group has not recorded any additional warranty provision relating to solar energy systems sold. PV construction
contracts entered into during the recent years included provisions under which the Group agreed to provide warranties to the customers.
The warranty the Group offers to its customers is identical to the warranty offered to the Group by its suppliers, therefore, the
Group passes on all potential warranty exposure and claims, if any, with respect systems sold by the Group to its suppliers. |
| Income Taxes | (t) Income Taxes The Group accounts for income taxes
under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable
to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases
and operating loss and tax credit carryforwards. Deferred 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 tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment
date. A valuation allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will
not be realized. The Company recognizes in the consolidated
financial statements the impact of a tax position, if that position is more likely than not of being sustained upon examination,
based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition
threshold, management presumes that the position will be examined by the appropriate taxing authority that has full knowledge of
all relevant information. In addition, a tax position that meets the more-likely-than-not recognition threshold is measured to
determine the amount of benefit to be recognized in the financial statements. The tax position is measured at the largest amount
of benefit that is greater than 50 percent likely of being realized upon settlement. The Group’s tax liability associated
with unrecognized tax benefits is adjusted periodically due to changing circumstances, such as the progress of the tax audits,
case law developments and new or emerging legislation. Such adjustments are recognized entirely in the period in which they are
identified. The Group records interest and penalties related to an uncertain tax position, if and when required, as part of income
tax expense in the consolidated statements of operations. No reserve for uncertainty tax position was recorded by the Group for
the years ended December 31, 2019, 2018 and 2017. |
| Revenue Recognition | (u) Revenue Recognition On January 1, 2018, the Group adopted
Accounting Standards Codification (“ASC”) No. 606, “Revenue from Contracts with Customers” (“ASC
606” or “Topic 606”) and applied the modified retrospective method to all contracts that were not completed as
of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period
amounts are not adjusted and continue to be reported in accordance with the Group’s historical accounting practices under
ASC Topic 605 “Revenue Recognition”. The Group has determined that the
impact of the transition to the new standard is immaterial to the Group’s revenue recognition model. Accordingly, the Group
has not made any adjustment to opening retained earnings. The Group’s accounting practices
under ASC Topic 606 are as followings: The Company generates revenue from
sales of PV components, electricity revenue with Power Purchase Agreements (“PPAs”), sales of PV project assets, bitcoin
mining equipment sales and hosting service, sales of pre-development solar projects, revenue from bitcoin mining and sales of hays
for the years ended December 31 2019, 2018 and 2017. Sale of PV components Revenue on sale of PV components
is recognized at a point in time following the transfer of control of such products to the customer, which typically occurs upon
shipment or acceptance of the customer depending on the terms of the underlying contracts. Electricity revenue with PPAs The Group sells energy generated
by PV solar power systems under PPAs. For energy sold under PPAs, the Group recognizes revenue each period based on the volume
of energy delivered to the customer (i.e., the PPAs off-taker) and the price stated in the PPAs. The Group has determined that
none of the PPAs contains a lease since (i) the purchaser does not have the rights to operate the PV solar power systems, (ii)
the purchaser does not have the rights to control physical access to the PV solar power systems, and (iii) the price that the purchaser
pays is at a fixed price per unit of output. Sale of PV project asset The Group’s sales arrangements
for PV projects do not contain any forms of continuing involvement that may affect the revenue or profit recognition of the transactions,
nor any variable considerations for energy performance guarantees, minimum electricity end subscription commitments. The Group
therefore determined its single performance obligation to the customer is the sale of a completed solar project. The Group recognizes
revenue for sales of solar projects at a point in time after the solar project has been grid connected and the customer obtains
control of the solar project. Bitcoin mining equipment sales and hosting service Revenue on sale of bitcoin
mining equipment is recognized at a point in time following the transfer of control of such products to the customer, which typically
occurs upon delivery of the products to the hosting site or receipt place assigned by the customer, installation and setting up
the products. Revenue for hosting service is recognized over time as services are performed and based on the output method related
to the time incurred during the service period. Sales of pre-development solar projects For sales of pre-development solar
projects in which the Group transfers 100% of the membership interest in solar projects to a customer, the Group recognizes all
of the revenue for the consideration received at a point in time when the membership interest was transferred to the customer,
which typically occurs when the Group delivered the membership interest assignment agreement to the customer. The contract arrangements may contain
provisions that can either increase or decrease the transaction price. These variable amounts generally are resolved upon achievement
of certain performance or upon occurrence of certain price reduction conditions. Variable consideration is estimated at each measurement
date at its most likely amount to the extent that it is probable that a significant reversal of cumulative revenue recognized will
not occur and true-ups are applied prospectively as such estimates change. Changes in estimates for sales of
pre-development solar projects occur for a variety of reasons, including but not limited to (i) EPC construction plan accelerations
or delays, (ii) product cost forecast changes, (iii) change orders, or (iv) occurrence of purchase price reduction conditions.
The cumulative effect of revisions to transaction prices are recorded in the period in which the revisions to estimates are identified
and the amounts can be reasonably estimated. Revenue from bitcoin mining The Company has entered into
a digital asset mining pool to provide computing power to the mining pool. Providing computing power in crypto asset transaction
verification services is an output of the Company’s ordinary activities. The provision of computing power is the only performance
obligation in the Company’s contracts with the mining pool. The transaction consideration the Company receives, if any,
is noncash consideration, which the Company measures at fair value on the date of receipt, which is not materially different than
the fair value at contract inception or the time the Company has earned the award from the mining pool. The consideration
is all variable. Because it is not probable that a significant reversal of cumulative revenue will not occur, the consideration
is constrained until the Company receives the consideration, at which time revenue is recognized. There is no significant financing
component in these transactions. Fair value of the digital asset
award received is determined using the average U.S. dollar spot rate of the related digital currency at the time of receipt. Sale of Alfalfa hays In 2019, the Company sells
alfalfa hays from United States to China. Revenue on sale of alfalfa hays is recognized at a point in time following the transfer
of control of such products to the customer, which typically occurs upon the acceptance of the products made by the customer. Disaggregation of revenues The following table illustrates
the disaggregation of revenue by revenue stream from continuing operations for the years ended December 31, 2019, 2018 and 2017:

Accounts receivable, current and noncurrent $ 16,539 $ 27,777
Advance from customers $ 17,632 $ 25,984 Advance from customers, which represent
a contract liability, represent mostly unrecognized amount received for customers. Advance from customers is recognized as (or
when) the Group performs under the contract. During the year ended December 31, 2019, 2018 and 2017, the Group recognized $8,159,
$11,365 and $326 that was included in the balance of advance from customers at January 1, 2019, 2018 and 2017, respectively. |
| Cost of Revenues | (v) Cost of Revenues Cost of revenues for PV components
is mainly from direct purchase price of PV components. Cost of revenues for PV project assets and pre-development solar projects
include all direct material, labor, subcontractor cost, land use right fee, and those indirect costs related to contract performance,
such as indirect labor, supplies and tools. Cost of revenues for bitcoin mining equipment and hosting service include direct purchase
of mining equipment, electricity fee and other indirect expense. Costs of electricity generation revenue include depreciation of
solar power project assets and costs associated with operation and maintenance of the project assets. Costs of bitcoin mining include
depreciation of bitcoin miners and hosting service fee. Cost of sales of hays is mainly the purchase price of raw materials. |
| Share-based Compensation | (w) Share-based Compensation The Group’s share-based payment
transactions with employees, such as restricted shares and share options, are measured based on the grant-date fair value of the
equity instrument issued. The fair value of the award is recognized as compensation expense, net of estimated forfeitures, over
the period during which an employee is required to provide service in exchange for the award, which is generally the vesting period. |
| Derivative Instruments | (x) Derivative Instruments The Company evaluates its convertible
debt to determine if the contract or embedded component of the contract qualifies as derivatives to be separately accounted for
in accordance with ASC 480, “Distinguish by Liabilities from Equity”, and ASC 815, “Derivatives and Hedging”.
The result of this accounting treatment is that the fair value of the embedded derivative, if required to be bifurcated, is marked-to-market
at each balance sheet date and recorded as a liability. The change in fair value is recorded in the consolidated statement of operations.
Upon conversion or exercise of a derivative instrument, the instrument is marked to fair value at the conversion date and then
that fair value is reclassified to equity. |
| Capitalized Interest | (y) Capitalized Interest The Group’s policy is to capitalize
interest cost incurred on debt during the construction of major projects exceeding three months. A reconciliation of total interest
cost to “Interest Expense” as reported in the consolidated statements of operations for the years ended December 31,
2019, 2018 and 2017 is as follows:
For the years ended December 31,
2019 2018 2017
Interest cost capitalized $ – $ 292 $ 1,607
Interest cost charged to expense 3,923 6,665 8,087
Total interest cost $ 3,923 $ 6,957 $ 9,694 |
| Gain on troubled debt restructuring | (z) Gain on Troubled Debt Restructuring The Group accounted the debt amendment
as a troubled debt restructuring when the transaction meets the two criteria: 1) The Group was experiencing financial difficulties;
2) the lender was granting a concession when the effective borrowing rate on the restructured debt is less than the effective borrowing
on the original debt. The difference between future undiscounted cash flows and the net carrying value of the original debt is
recognized as gain on troubled debt restructuring, and the carrying value of the debt is adjusted to the future undiscounted cash
flow amount. |
| Segment Reporting | (aa) Segment Reporting Operating segments are defined as
components of a company which separate financial information is available that is evaluated regularly by the operating decision
maker in deciding how to allocate resources and assessing performance. The Group’s chief operating decision maker is the
Chairman, Mr. Peng. Based on the financial information presented to and reviewed by the chief operating decision maker, the Group
has determined that it has a single operating and reporting segment for the years ended December 31, 2019, 2018 and 2017. |
| Net Loss Per Share | (ab) Net Loss Per Share Basic loss per share is computed
by dividing net loss attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding for the
period. Diluted loss per share is calculated by dividing net loss 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 period. Potentially dilutive shares are excluded from the computation if their effect is anti-dilutive. |
| Comprehensive Loss | (ac) Comprehensive Loss U.S. GAAP generally requires that
recognized revenue, expenses, gains and losses be included in net income or loss. Although certain changes in assets and liabilities
are reported as separate components of the equity section of the consolidated balance sheet, such items, along with net income,
are components of comprehensive income or loss. The components of other comprehensive income or loss consist solely of foreign
currency translation adjustments. |
| Commitments and Contingencies | (ad) 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. If a potential material loss contingency is not probable but is reasonably
possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the
range of possible loss if determinable and material, is disclosed. Legal costs incurred in connection with loss contingencies are
expensed as incurred. |
| Leases | (ae) Leases In February 2016, the FASB issued
ASU 2016-12, Leases (ASC Topic 842), which amends the leases requirements in ASC Topic 840, Leases. Under the new lease accounting
standard, a lessee will be required to recognize a right-of-use asset and lease liability for most leases on the balance sheet.
The new standard also modifies the classification criteria and accounting for sales-type and direct financing leases, and enhances
the disclosure requirements. Leases will continue to be classified as either finance or operating leases. The Group adopted ASC Topic 842
using the modified retrospective transition method effective January 1, 2019. There was no cumulative effect of initially applying
ASC Topic 842 that required an adjustment to the opening retained earnings on the adoption date nor revision of the balances in
comparative periods. As a result of the adoption, the Group recognized a lease liability and right-of-use asset for each of the
existing lease arrangement. The adoption of the new lease standard does not have a material impact on the consolidated statements
of operations or the consolidated statements of cash flows. The Group determines if an arrangement
is a lease at inception. The lease payments under the lease arrangements are fixed. Non-lease components include payments for building
management, utilities and property tax. It separates the non-lease components from the lease components to which they relate. Lease assets and liabilities are
recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine
the present value of the future lease payments is the Group’s incremental borrowing rate, because the interest rate implicit
in the leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized
basis with similar terms and payments, and in economic environments where the leased asset is located. The lease terms include
periods under options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.
The Group generally uses the base, non-cancelable, lease term when determining the lease assets and liabilities. |
| Recent Accounting Pronouncements | (af) Recent Accounting Pronouncements Recently Adopted Accounting Standards In May 2014, the Financial Accounting
Standards Board (FASB) issued Topic 606, which supersedes the revenue recognition requirements in Topic 605. The Group adopted
Topic 606 as of January 1, 2018 using the modified retrospective transition method applied to those contracts which were not completed
as of January 1, 2018. See Note 3(u) “Revenue Recognition” above for further details. In February 2016, the FASB issued
ASU 2016-12, Leases (ASC Topic 842), which amends the leases requirements in ASC Topic 840, Leases. The Group adopted ASC Topic
842 using the modified retrospective transition method effective January 1, 2019. There was no cumulative effect of initially applying
ASC Topic 842 that required an adjustment to the opening retained earnings on the adoption date nor revision of the balances in
comparative periods. See Note 3(ae) “Leases” above for further details. In November 2016, the FASB issued
ASU No. 2016-18, Statement of Cash Flows (Topic 230): “Restricted Cash” (“ASU 2016-18”). ASU 2016-18 requires
that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally
described as restricted cash or restricted cash equivalents. This update is effective in fiscal years, including interim periods,
beginning after December 15, 2017 and early adoption is permitted. The adoption of this guidance will result in the inclusion of
the restricted cash balances within the overall cash balance and removal of the changes in restricted cash activity, as a result,
the Company no longer presents transfers between cash and cash equivalents and restricted cash in the statement of cash flows.
Furthermore, an additional reconciliation will be required to reconcile cash, cash equivalents, and restricted cash reported within
the consolidated balance sheets to sum to the total shown in the consolidated statement of cash flows. The Group has already disclosed
the restricted cash separately on its consolidated balance sheets. Beginning January 1, 2018, the Group has adopted and included
the restricted cash balances on the consolidated statement of cash flows and reconciliation of cash, cash equivalent, and restricted
cash within its consolidated statements of balance sheet and consolidated statement of cash flows. This guidance has been applied
retrospectively to the consolidated statement of cash flows for the year ended December 31, 2017, which required the Company to
recast each prior reporting period presented. In January 2017, the FASB issued
AUS No. 2017-01, “Business Combination (Topic 805): Clarifying the Definition of a Business”. The Group adopted it
on January 1, 2018 and applied the new definition of a business prospectively for acquisitions made subsequent to December 31,
2017. See Note 3 (f) “Business Acquisition” above for further details. Accounting Pronouncements Issued
But Not Yet Adopted In August 2018, the FASB issued
ASU No. 2018-13, Fair Value Measurement (Topic 820)-Disclosure Framework-Changes to the Disclosure Requirements for Fair Value
Measurement. ASU 2018-13 removes the amounts and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy
and the valuation processes for Level 3 fair value measurements; modifies certain disclosure requirements in Topic 820; and require
additional disclosures such as the range and weighted average of significant unobservable inputs used to develop Level 3 measurements
etc. ASU No. 2018-13 is effective for the Company beginning in the first quarter of fiscal year 2020. The Company does not expect
this guidance will have a material impact on its consolidated financial statements. On December 18, 2019, the FASB issued
ASU No. 2019-12, Income taxes (Topic 740), Simplifying the Accounting for Income Taxes. This guidance amends ASC Topic 740 and
addresses several aspects including 1) evaluation of step-up tax basis of goodwill when there is not a business combination, 2)
policy election to not allocate consolidated taxes on a separate entity basis to entities not subject to income tax, 3) accounting
for tax law changes or rates during interim periods, 4) ownership changes from equity method investment to subsidiary or vice versa,
5) elimination of exception to intraperiod allocation when there is gain in discontinued operations and a loss from continuing
operations, 6) treatment of franchise taxes that are partially based on income. The guidance is effective for calendar year-end
public entities on January 1, 2021 and other entities on January 1, 2022. The Company is evaluating the impact of this guidance
on its consolidated financial statements. The Group does not believe other
recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated
financial position, statements of operations and cash flows. |
