Photovoltaic manufacturer SEG Solar announced the construction of a new 4 GW solar module production plant in Houston , Texas , as part of its industrial expansion strategy and manufacturing localization in the United States .
With this new facility, the company will increase its total annual module production capacity in the United States to approximately 6 GW , consolidating its position as one of the largest manufacturers of 100% American solar modules in the market.
According to the company, the new factory will begin commercial operations during the third quarter of 2026.
The facility will cover approximately 500,000 square feet and will require an investment exceeding $200 million. Furthermore, the project anticipates the creation of up to 800 new jobs.
The expansion follows the launch of the company's first 2 GW module factory in the United States and is part of a broader industrial integration strategy driven by SEG Solar.
“The plant is designed with the flexibility needed to incorporate next-generation technologies, including HJT, as the industry evolves,” said Timothy Johnson, vice president of Operations at SEG Solar.
The company also highlighted that domestic production will improve the traceability, quality, and delivery speed of solar modules for utility-scale, commercial, and residential customers.
Vertical integration and strategy in the face of the commercial context
The announcement is also linked to SEG's previously revealed project to develop a 5 GW ingot and wafer plant in Indonesia, with construction scheduled to begin in the second quarter of 2026.
Once completed, the company will seek to consolidate a vertically integrated supply chain, encompassing everything from ingots and wafers to solar cells and modules.
This move gains relevance amid the tightening of the regulatory and commercial framework in the United States for the photovoltaic industry, especially regarding local content requirements, traceability and restrictions linked to entities considered FEOCs (Foreign Entity of Concern).
SEG claimed to have been validated by multiple independent third parties as a “non-PFE” company for FEOC compliance purposes and assured that it currently supplies modules with “non-PFE” solar cells.
Manufacturer expansion in the United States
SEG Solar's decision adds to the growing wave of manufacturing investments in the United States by photovoltaic companies seeking to take advantage of tax incentives, reduce trade exposure and strengthen local supply chains.
Founded in 2021 and headquartered in Houston, the company reported that it has already shipped more than 7.5 GW of solar modules globally and reached a production capacity of 6.5 GW by the end of 2025.
FES's next stops
