Despite various challenges, U.S. companies say the American solar manufacturing industry continues to grow and develop.

The solar supply chain comprises several key stages, typically carried out in separate factories—starting with processing polysilicon into a form usable for solar cells. Next comes solar cell manufacturing: these cells are small square wafers coated with polysilicon. Manufacturers also rely on suppliers of glass, mounting structures, and electronic components. The final step is assembling all components into a finished panel—a process Vagneur-Jones compares to assembling IKEA furniture. Vagneur-Jones believes First Solar holds a strong position, having manufactured solar panels and managed its supply chain in the U.S. for decades. The company expects its U.S. factories to reach an annual production capacity of 14 gigawatts (GW) of solar panels by the end of 2026. This capacity will be distributed across three factories in Ohio, one in Alabama, and a forthcoming facility in Louisiana. "It’s important to recognize that some manufacturers are planning things that can be taken more seriously than others," he said. He also sees potential for success among newer Korean solar manufacturers like Hanwha Q CELLS, which has operated in Dalton, Georgia since 2019 and is now undertaking major expansion there. T1 Energy belongs to this category of newer, smaller firms planning to scale up production and build a U.S.-based supply chain. Prior to its rebranding announcement in February, T1 was known as Freyr Battery. This Norway-originated company had initially planned to open a U.S. battery factory in Georgia—but later abandoned that plan and instead pivoted to solar manufacturing, starting with a solar panel factory near Dallas acquired from a Chinese company. In March, T1 announced plans to build a factory in Rockdale, Texas—located about 60 miles northeast of Austin. The facility will have the capacity to produce 5 GW of solar cells: thin, square wafers coated with processed silicon. A typical solar panel contains dozens of such cells. Its partnership with Corning illustrates how T1 intends to construct its supply chain. Beginning in the second half of 2026, T1 will use polysilicon processed at Corning’s Michigan facility. These materials will be shipped to T1’s planned Rockdale cell manufacturing plant, then onward to its Dallas facility for final solar panel assembly. According to T1 and Corning, this collaboration will support approximately 5,800 new jobs. "This landmark supply chain agreement with Corning will revitalize America through scalable, reliable, and low-cost energy," said Daniel Barcelo, Chairman and CEO of T1, in a statement. "This is American companies building in America—and safeguarding America’s energy security. The U.S. must establish critical energy supply chains rooted in domestic manufacturing capacity and industrial technology." T1 is part of a rapidly expanding cluster of solar manufacturing enterprises in Texas.

T1 Energy, a U.S. affiliate of Trina Solar, monetizes $160 million: unveiling the policy-financing game.

Follow us on 【EnSight New Energy Vision — Seeing Value】 Recently, U.S.-based T1 Energy announced it had successfully completed its first sale of Production Tax Credits (PTCs) under Section 45X of the Inflation Reduction Act (IRA) to an investment-grade buyer, generating $160 million in proceeds. This substantial cash inflow did not come from component sales but rather from astute financial engineering leveraging U.S. government subsidy policies. $160 Million in “Immediate Cash” The Financial Magic of Tax Credits The transaction employed the tax credit transfer mechanism, with T1 selling each dollar of tax credit at a price of 91 cents. Citigroup Global Markets served as financial advisor. Final settlement and adjustment will occur in February 2026, based on T1’s December 2025 component output. In simple terms, for a company like T1—still ramping up production and expanding capacity—the future tax credits it will generate far exceed its current taxable income. By selling these “future tax-offset rights” upfront to banks or investment funds with large tax liabilities, T1 secures immediate liquidity without resorting to traditional debt or equity financing. Meanwhile, buyers acquire a reliable “tax-reduction asset” at a discount. This $160 million transaction effectively “monetizes” anticipated policy subsidies into immediate cash flow—funds that will directly support operations at T1’s G1 Dallas module factory and construction of its G2 Austin advanced battery factory. Thus, a perfect closed loop emerges: “policy infusion → cash injection → capacity expansion.” This is no longer the conventional “manufacture–sell–profit” logic; rather, it represents an upgraded capital game: “manufacture–generate subsidies–financial monetization–reinvest in manufacturing.” Trina Solar’s “Shell” and “Core” Compliance Wisdom Under FEOC Pressure Although T1 operates as an independent U.S. public company (NYSE ticker: TE), against the backdrop of stringent controls imposed by the U.S. “One Big Beautiful Bill Act” (OBBA) on “Foreign Entities of Concern” (FEOCs), T1 serves as Trina Solar’s pivotal platform for achieving “localized manufacturing” in the U.S. market. In December 2024, T1 acquired Trina Solar’s U.S. manufacturing assets for $621 million, naming the facility G1 Dallas Factory. (Read original article: [Capacity] Another 5 GW! U.S. Solar Giant Invests $1.1 Billion in Texas Triangle Region) Through subsequent equity transfers, Trina Solar currently holds approximately 17.4% of T1’s shares—a stake deliberately calibrated below FEOC-related regulatory thresholds. This ensures T1’s eligibility for U.S. federal subsidies while preserving Trina Solar’s channels for technological collaboration and financial returns.
