T1 Energy Signs New Advanced Solar Module Offtake Deals Totaling 1.58+ GW; Terms Not Disclosed

Through its latest offtake contracts, including with subsidiaries of independent power producer Avantus, T1 Energy expects to supply high-performance, high-efficiency, TOPCon modules from its G1_Dallas solar module facility in 2027 and 2028. The modules are expected to use a blend of imported solar cells and domestically produced cells from T1’s G2_Austin new solar cell fab. T1 now has more than 4GW of its 2027 manufacturing capacity under contract.

T1 continues to increase the domestic content of its modules. T1 began construction of G2_Austin, its solar cell fab in Rockdale, Texas, in December 2025. The first 2.1GW phase is expected to produce cells in Q1 2027. T1 expects to offer modules with greater than 60% domestic content in 2027.

The deals mark a continuation of T1’s commercial strategy to offer customers a traceable and reliable solar supply chain. Leveraging its 5GW solar module facility, G1_Dallas, T1 offers integrated solutions that help clients optimize project schedules, financing, and returns.

In addition to building a leading domestic solar supply chain through reshoring manufacturing, T1 has also repatriated key solar technology. T1’s solar modules feature Tunnel Oxide Passivated Contact ("TOPCon") solar cells, which T1 believes is the most advanced, highly efficient commercially viable solar technology available. In July, the company announced it had acquired foundational TOPCon solar patents and other intellectual property.
