SEG Solar ramps up with a new 4 GW solar factory in Texas

SEG Solar is expanding its US manufacturing footprint again, this time with a new 4-gigawatt solar module factory planned for Houston, Texas.

The company said today that the new facility will add nearly 500,000 square feet of manufacturing space and increase SEG’s total US solar module production capacity to around 6 GW annually. Commercial operations are expected to begin in Q3 2026.

SEG says the Houston project represents more than $200 million in investment and will create up to 800 jobs.

The expansion comes as US solar manufacturers continue to build more production capacity amid growing demand for domestically made clean energy equipment and tighter scrutiny around solar supply chains.
