SEG Solar, a Houston-based manufacturer, has announced plans to establish a new 4 GW solar panel manufacturing facility in its hometown of Houston, Texas.
The expansion builds on the company’s existing footprint of 2 GW and is expected to bring total domestic production capacity to approximately 6 GW. Commercial activities at the site are expected to start in the third quarter of 2026.
The 46,4511 m2 facility represents an investment of more than $200 million and is expected to create 800 jobs. This move reflects the company’s strategy to increase domestic content and provide better traceability for its partners.
Timothy Johnson, vice president of operations at SEG Solar, said the facility marks a milestone for the company and is designed with the flexibility to integrate next-generation technologies, such as heterojunction, as the industry evolves.
The project contributes to a broader increase in regional production, as solar panel production in Texas is expected to do surpass 15 GW by 2026. This growth is driven by a favorable regulatory environment and the state’s proximity to major logistics hubs.
SEG Solar said it has also been validated as a non-prohibited foreign entity for compliance purposes (FEOC), which is a critical factor for developers seeking to qualify for federal tax benefits.
In addition to the expansion in Texas, the company is developing a 5 GW billet and wafer production line in Indonesia. Construction at that location is scheduled for the second quarter of 2026. Once the project is complete, the company will have a vertically integrated supply chain that includes ingots, wafers and cells.
SEG Solar, founded in 2021, reported that it would supply more than 7.5 GW of modules worldwide by the end of 2025.
