HoustonMay 8, 2026 /PRNewswire/ — SEG Solar (referred to as “SEG”), a leading U.S. solar module manufacturer, today announced that it will build a new 4-gigawatt (GW) solar manufacturing facility in Houston, Texas. Building on the success of its first 2 GW solar module factory, this expansion will increase SEG’s total annual module production capacity in the United States to approximately 6 GW. The new facility is expected to begin commercial operations in the third quarter of 2026.
The new factory spans nearly 500,000 square feet, with an investment exceeding $200 million, and is expected to create up to 800 new jobs. This expansion is part of SEG’s long-term localization strategy and will position SEG as one of the largest 100% domestically owned module manufacturers in the United States. Modules produced domestically will offer improvements in product quality, traceability, and delivery speed, delivering greater value to partners and customers.
Timothy Johnson, Vice President of Operations at SEG Solar, stated: “This new facility is a significant milestone in SEG’s development. It will further strengthen our manufacturing capabilities in the United States while supporting ongoing technological innovation. The factory is designed with flexibility to integrate next-generation technologies, including heterojunction (HJT), as the industry evolves.”
This announcement follows SEG’s previous disclosure of plans to build a 5 GW ingot and wafer manufacturing facility in Indonesia, with construction expected to begin in the second quarter of 2026. Once completed, this facility will enable SEG to deliver modules through a fully integrated supply chain covering ingots, wafers, and cells — a capability that is increasingly important amid evolving policy and trade environments. SEG has been certified by multiple independent third-party organizations as a non-prohibited foreign entity (non-PFE) compliant with U.S. Foreign Entity of Concern (FEOC) rules, and the company can currently offer modules using solar cells sourced from non-prohibited foreign entities.
