T1 Energy secures polysilicon and wafer supply agreements with Hemlock Semiconductor and Corning to support U.S. solar module manufacturing
Type: Supply Agreement · Technology: Solar · Country: United States · Announced: 2026-08-13
T1 Energy finalized supply contracts with Hemlock Semiconductor and Corning for American polysilicon and wafers, reinforcing its vertically integrated U.S. solar supply chain. The agreements underpin T1 Energy’s 5GW solar module facility, G1_Dallas, designed to produce modules capable of powering over one million American homes annually. Located in Dallas, Texas, the facility represents a cornerstone of T1 Energy’s strategy to localize solar manufacturing amid rising global competition. Hemlock Semiconductor, a Michigan-based producer, supplies the critical polysilicon feedstock, while Corning contributes high-purity wafers essential for solar cell production. These supply agreements were disclosed alongside T1 Energy’s December 2024 transaction that repositioned the company from battery development to solar integration, marking a strategic pivot toward domestic clean energy infrastructure.
