Accounting Policies [Abstract]
Basis of Presentation	Note 1. Basis of Present ation The condensed consolidated financial statements included herein have been prepared by us without audit, pursuant to the rules and regulations of the SEC and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in our Annual Report on Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted, as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading. The accompanying condensed consolidated financial statements reflect, in the opinion of our management, all normal recurring adjustments necessary to present fairly our financial position at June 30, 2021, and the results of our operations, comprehensive income (loss) and cash flows for the periods presented. Interim results for the three and six months ended June 30, 2021 and 2020 are not necessarily indicative of the results to be expected for the full years. Certain prior period amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying condensed consolidated financial statements include the accounts of TPI Composites, Inc. and all of our majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated. References to TPI Composites, Inc, the “Company,” “we,” “us” or “our” in these notes refer to TPI Composites, Inc. and its consolidated subsidiaries. Accounting Pronouncements Recently Adopted Accounting Pronouncements Convertible Instruments In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This ASU is intended to simplify the accounting for certain convertible instruments with characteristics of both liability and equity. This ASU removes certain accounting models which separate the embedded conversion features from the host contract for convertible instruments. As a result, after the adoption of this guidance, an entity’s convertible debt instrument will be wholly accounted for as debt. This ASU also expands disclosure requirements for convertible instruments and simplifies areas of the guidance for diluted earnings-per-share calculations by requiring the use of the if-converted method. This ASU is effective for all public business entities (other than smaller reporting companies) for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020 and can be adopted on either a fully retrospective or modified retrospective basis. An entity should adopt the guidance at the beginning of its annual fiscal year. We adopted this standard on January 1, 2021 on a modified retrospective basis and it did not have a material effect on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This ASU only applies to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. This ASU is effective for all entities beginning on March 12, 2020 and entities may elect to apply the ASU prospectively through December 31, 2022. The FASB later issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope , to clarify the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. We are currently evaluating the impact this guidance may have on our condensed consolidated financial statements and related disclosures.

The geography of Europe, the Middle East and Africa comprises the EMEA segment. Contract Assets and Liabilities Contract assets consist of the amount of revenue recognized over time for performance obligations in production where control has transferred to the customer but the contract does not yet allow for the customer to be billed. Typically, customers are billed when the product finishes production and meets the technical specifications contained in the contract. The majority of the contract asset balance relates to materials procured based on customer specifications. The contract assets are recorded as current assets in the condensed consolidated balance sheets. Contract liabilities consist of advance payments in excess of revenue earned. These amounts primarily represent progress payments received as precision molding and assembly systems are being manufactured. The contract liabilities are recorded as current liabilities in the condensed consolidated balance sheets and are reduced as we record revenue over time. These contract assets and liabilities are reported on the condensed consolidated balance sheets net on a contract-by-contract basis at the end of each reporting period. Contract assets and contract liabilities consisted of the following: June 30, December 31, 2021 2020 $ Change (in thousands) Gross contract assets $ 234,045 $ 223,428 $ 10,617 Less: reclassification from contract liabilities ( 2,265 ) ( 6,500 ) 4,235 Contract assets $ 231,780 $ 216,928 $ 14,852 June 30, December 31, 2021 2020 $ Change (in thousands) Gross contract liabilities $ 4,523 $ 7,114 $ ( 2,591 ) Less: reclassification to contract assets ( 2,265 ) ( 6,500 ) 4,235 Contract liabilities $ 2,258 $ 614 $ 1,644 Contract assets increased by $ 14.9 million from December 31, 2020 to June 30, 2021 due to an increase in customer specific material purchases and incremental unbilled production during the six months ended June 30, 2021. Contracts liabilities increased by $ 1.6 million from December 31, 2020 to June 30, 2021 primarily due to amounts billed to a customer in advance of the production of precision molding and assembly systems during the six months ended June 30, 2021. For the three and six months ended June 30, 2021 , we recognized $ 0.1 million and $ 0.1 million, respectively, of revenue related to precision molding and assembly systems and wind blades, which was included in the corresponding contract liability balance at the beginning of the period. Performance Obligations Remaining performance obligations represent the transaction price for which work has not been performed and excludes any unexercised contract options. The transaction price includes estimated variable consideration as determined based on the estimated production output within the range of the contractual guaranteed minimum volume obligations and production capacity. As of June 30, 2021, the aggregate amount of the transaction price allocated to the remaining performance obligations to be satisfied in future periods was approximately $ 3.2 billion. We estimate that we will recognize the remaining performance obligations as revenue as follows: $ % of Total (in thousands) Year Ending December 31, Remainder of 2021 $ 874,559 27.3 % 2022 1,492,816 46.7 2023 712,885 22.3 2024 118,962 3.7 Total remaining performance obligations $ 3,199,222 100.0 % For the three and six months ended June 30, 2021 , net revenue recognized from our performance obligations satisfied in previous periods decreased by $ 4.0 million and $ 12.5 million, respectively, as compared to increases of $ 5.8 million and $ 0.6 million, respectively, in the same periods in 2020. The current year decreases primarily relates to changes in certain of our estimated total contract values and related direct costs to complete the performance obligations.

Risks And Uncertainties [Abstract]
Significant Risks and Uncertainties	Note 3. Significant Risks and Uncertainties Our revenues and receivables are earned from a small number of customers. As such, our production levels are dependent on these customers’ orders. See Note 13, Concentration of Customers . We may be required to reinstate temporary production suspensions or volume reductions at our manufacturing facilities to the extent there are new resurgences of COVID-19 cases in the regions where we operate or there is an outbreak of positive COVID-19 cases in any of our manufacturing facilities. In addition, our global supply chain may in the future be adversely affected if the COVID-19 pandemic persists. In 2021, there have been both significant price increases and supply constraints with respect to resin and carbon fiber, which are key raw materials that we use to manufacture our products, as well as increases in logistics costs to obtain raw materials. We expect that the price of resin and carbon fiber will remain at elevated levels for the remainder of 2021. Approximately 55 % of the resin and resin systems we use are purchased under contracts either controlled or borne by two of our customers and therefore these customers receive/bear 100 % of any increase in resin prices. With respect to our other customer supply agreements, our customers typically bear 70 % of any raw material price increases. If the supply of resin feedstocks and carbon fiber continue to be constrained for an extended period of time, such shortages could impact our ability to meet our customers’ forecasted demand for our products for the remainder of 2021 and have a further material adverse impact on our results of operations. We maintain our U.S. cash in bank deposit and money market accounts that, at times, exceed U.S. federally insured limits. U.S. bank accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) in an amount up to $ 250,000 during 2021 and 2020. U.S. money market accounts are not guaranteed by the FDIC. At June 30, 2021 and December 31, 2020, we had $ 55.2 million and $ 68.9 million, respectively, of cash in bank deposit and money market accounts in high quality U.S. banks, which was in excess of FDIC limits. We have not experienced losses in any such accounts. We also maintain cash in bank deposit accounts outside the U.S. with no insurance. At June 30, 2021, this included $ 58.7 million in China, $ 5.1 million in Turkey, $ 2.3 million in Mexico, $ 1.5 million in India and $ 0.3 million in other countries. As of December 31, 2020, this included $ 47.4 million in China, $ 6.0 million in Turkey, $ 5.0 million in India, $ 2.1 million in Mexico and $ 0.5 million in other countries. We have not experienced losses in these accounts. In addition, at June 30, 2021 and December 31, 2020, we had short-term deposits in interest bearing accounts in China of $ 0.2 million and $ 0.3 million, respectively, which are reported as restricted cash in our condensed consolidated balance sheets. Certain of our debt agreements are either tied to LIBOR or the Euro Interbank Offered Rate (EURIBOR) and certain of them have associated interest rate hedges. Due to the relatively low LIBOR and EURIBOR rates in effect as of June 30, 2021 , a 10 % change in the LIBOR or EURIBOR rate would not have had a material impact on our future earnings, fair values or cash flows.

Income Tax Disclosure [Abstract]
Income Taxes	Note 9. Income Taxes The income tax provisions for the three and six months ended June 30, 2021 were lower than for the corresponding periods in 2020 primarily due to the change in the mix of earnings of foreign jurisdictions and U.S. tax on foreign earnings in the comparable periods, partially offset by the recording of a full U.S. valuation allowance during the three months ended June 30, 2021 and an increase in our uncertain tax positions for the three and six months ended June 30, 2021 as compared to the same periods in 2020. No changes in tax law occurred during the six months ended June 30, 2021 , which had a material impact on our income tax provision. We do not record a deferred tax liability related to unremitted foreign earnings as we maintain our assertion to indefinitely reinvest our unremitted foreign earnings.

Basis of Presentation	The condensed consolidated financial statements included herein have been prepared by us without audit, pursuant to the rules and regulations of the SEC and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2020 included in our Annual Report on Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted, as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading. The accompanying condensed consolidated financial statements reflect, in the opinion of our management, all normal recurring adjustments necessary to present fairly our financial position at June 30, 2021, and the results of our operations, comprehensive income (loss) and cash flows for the periods presented. Interim results for the three and six months ended June 30, 2021 and 2020 are not necessarily indicative of the results to be expected for the full years. Certain prior period amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying condensed consolidated financial statements include the accounts of TPI Composites, Inc. and all of our majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated. References to TPI Composites, Inc, the “Company,” “we,” “us” or “our” in these notes refer to TPI Composites, Inc. and its consolidated subsidiaries.
Accounting Pronouncements	Accounting Pronouncements Recently Adopted Accounting Pronouncements Convertible Instruments In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This ASU is intended to simplify the accounting for certain convertible instruments with characteristics of both liability and equity. This ASU removes certain accounting models which separate the embedded conversion features from the host contract for convertible instruments. As a result, after the adoption of this guidance, an entity’s convertible debt instrument will be wholly accounted for as debt. This ASU also expands disclosure requirements for convertible instruments and simplifies areas of the guidance for diluted earnings-per-share calculations by requiring the use of the if-converted method. This ASU is effective for all public business entities (other than smaller reporting companies) for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020 and can be adopted on either a fully retrospective or modified retrospective basis. An entity should adopt the guidance at the beginning of its annual fiscal year. We adopted this standard on January 1, 2021 on a modified retrospective basis and it did not have a material effect on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This ASU only applies to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. This ASU is effective for all entities beginning on March 12, 2020 and entities may elect to apply the ASU prospectively through December 31, 2022. The FASB later issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope , to clarify the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. We are currently evaluating the impact this guidance may have on our condensed consolidated financial statements and related disclosures.
