T1, Corning reach deal to make fully American-made solar panels

U.S. solar company T1 Energy and specialty glass maker Corning have forged a landmark agreement to establish a fully domestic U.S. solar supply chain, encompassing polysilicon, wafers, cells, and panels. This strategic partnership aims to capitalize on U.S. policy, specifically the 'One Big Beautiful Bill Act,' which restricts federal clean energy tax credits for projects utilizing components from 'foreign entities of concern,' thereby reducing reliance on Chinese manufacturing and boosting American energy security. Under the deal, Corning will supply wafers from its Michigan factory to T1's Texas facilities starting in H2 2026, collectively creating 6,000 jobs and expanding on an existing polysilicon contract.

Analysis

T1 Energy (TE) and Corning (GLW) have announced a strategic agreement to create a fully domestic U.S. solar supply chain, a direct response to U.S. industrial policy aimed at reducing reliance on Chinese manufacturing. The partnership is explicitly designed to capitalize on the "One Big Beautiful Bill Act," which restricts federal clean energy tax credits for projects using components from foreign entities of concern. Under the terms, Corning will supply U.S.-made solar wafers from its Michigan factory to T1's Texas facilities, with deliveries commencing in the second half of 2026. This deal expands an existing polysilicon contract and is projected to support approximately 6,000 jobs in Michigan and Texas. For Corning, this agreement, following similar deals with Suniva and Heliene, solidifies its pivotal role in the onshoring of the U.S. solar industry. For T1 Energy, it secures a critical component supply that is compliant with federal incentives, positioning it to meet growing demand for American-made panels and enhancing its energy security narrative, as articulated by CEO Daniel Barcelo.

Key Decisions for Investors

• Given the strong alignment with U.S. industrial policy and tax incentives, investors should view this partnership as a significant long-term catalyst for both T1 Energy and Corning, potentially securing a durable demand stream and mitigating geopolitical supply chain risks.
• Monitor key execution milestones, particularly the development of T1's Austin cell facility and the start of wafer supply in H2 2026, as any delays could defer the material financial benefits of the agreement.
• Consider that this deal significantly de-risks T1 Energy's supply chain and enhances its competitive positioning within the domestic market, making it a key potential beneficiary of the U.S. renewable energy transition.
