In a landmark move that underscores the shifting dynamics of global clean energy manufacturing, Chinese solar giant Trina Solar has completed the sale of a massive 5-gigawatt solar module factory in Texas to T1 Energy, formerly known as FREYR Battery.

The transaction, which was initiated and approved by T1 Energy's board of directors in November 2024, represents a significant milestone in the ongoing trend of localizing critical green technology production within the United States. Finalized on December 23, 2025, the deal sees Trina Solar retaining a 17% equity stake in T1 Energy and receiving $100 million in cash.

This strategic move comes against the backdrop of increasing global protectionism and a growing emphasis on domestic manufacturing of renewable energy infrastructure. The Inflation Reduction Act of 2022, passed under President Joe Biden's administration, has played a crucial role in incentivizing such investments in American solar and battery manufacturing.

T1 Energy's journey is particularly noteworthy. Previously focused on battery production, the company pivoted after earlier plans for a battery factory in Georgia were halted during political transitions. This solar module factory acquisition represents a resilient and adaptive approach to clean energy manufacturing.

The transfer signals a broader trend of nations seeking to secure their supply chains for critical green technologies. With solar panels and batteries increasingly viewed as essential infrastructure for future energy systems, companies like T1 Energy are positioning themselves at the forefront of this transformative industrial shift.

Industry observers see this transaction as more than just a business deal—it's a testament to the United States' commitment to building a robust, domestically-driven clean energy ecosystem. As geopolitical landscapes continue to evolve, strategic investments like these will play a pivotal role in shaping the global renewable energy landscape.
