On August 15, according to foreign media reports, American photovoltaic manufacturer T1 Energy (hereinafter referred to as T1) and glass giant Corning reached an agreement to jointly build a domestic supply chain covering polysilicon, silicon wafers, batteries and solar modules.
T1 said it would purchase high-purity polysilicon and solar wafers from Corning's manufacturing park in Michigan and deliver them to its new solar cell factory (G2 Austin) in Austin, Texas, for battery production from the second half of 2026. The solar cells produced by the Austin plant will be assembled and produced in T1's existing module plant in Dallas (G1 Dallas) .
Earlier, in March 2025, T1 announced a plan in its 2024 annual performance report to build a 5G W solar cell manufacturing plant (G2 Austin) in Milam County, Texas, USA. The investment is about 850 million US dollars (about 6.15 billion RMB).
T1's plant in northeast Austin, Texas, USA, is named "G2 Austin", while the existing solar module plant in Wilmer, Texas, is called "G1 Dallas".
It is reported that G1 Dallas is a Texas Wilmer component plant acquired by T1 Energy from Trina Solar in November 2024, which began production on November 1, 2024, and in the first quarter of 2025. G1 Dallas has produced more than 440MW PV modules . (For details, please refer to the signing of the 5G W photovoltaic cell project of Trina Solar's US shareholding company!)
