SEG Solar, a U.S. solar module manufacturer, has announced plans to establish a new 4-gigawatt (GW) solar modules manufacturing facility in Houston, Texas. This expansion builds on its existing 2 GW facility and will increase the company’s total annual U.S. production capacity to approximately 6 GW. Commercial operations are expected to begin in Q3 2026.
The new facility will span nearly 500,000 square feet and represents an investment of over $200 million. It is expected to create up to 800 new jobs and is part of SEG Solar’s broader localization strategy to strengthen domestic manufacturing capabilities.
According to the company, the facility is designed to support advanced solar technologies, including HJT, and enhance flexibility as industry requirements evolve.
“This new facility marks an important milestone for SEG,” said Timothy Johnson, VP of Operations of SEG Solar. “It will further strengthen our U.S. manufacturing capabilities while supporting ongoing technology innovation. The plant is designed with the flexibility to integrate next-generation technologies, including HJT, as the industry evolves.”
SEG Solar also noted its previously announced plan to develop a 5 GW ingot and wafer manufacturing facility in Indonesia, expected to begin construction in Q2 2026. Once completed, the company aims to operate a more integrated supply chain spanning ingots, wafers, and cells.
