SEG Solar plans 4.6 GW third U.S. manufacturing site in Greater Houston

The facility is planned as a 1.15 million square-foot factory and warehouse, with construction expected to finish by March 2027 and commercial production to begin two months later. The announcement follows SEG’s second U.S. site, a 4 GW factory near Houston scheduled for an August 2026 opening. The story matters because U.S. solar manufacturing growth is increasingly tied to domestic supply-chain rules, traceability, and technology shifts beyond standard module assembly.
