<p>Texan solar module manufacturer <a href="https://www.segsolar.com/">SEG Solar</a> is planning for a new module production plant in the Lone Star State, company officials say, with commercial operations expected to begin in Q3 2026.</p>
<p>At nearly 500,000 square feet, the Houston-area facility represents a companywide investment of over $200 million. The plant also expects to provide 800 jobs to the Harris County area. The expansion is part of a long-term strategy by SEG Solar to localize its manufacturing efforts, representatives say, with the end result making the firm one of the largest 100% U.S.-owned module manufacturers in the industry.</p>
<p>The facility “marks an important milestone for SEG,” according to Timothy Johnson, VP of Operations of SEG Solar. Johnson has been with the company since March of this year, following a seven year stint at <a href="https://www.engie.com/en">ENGIE</a>.</p>
<p>“(The new plant) will further strengthen our U.S. manufacturing capabilities while supporting ongoing technology innovation,” he says. “The plant is designed with the flexibility to integrate next-generation technologies, including HJT, as the industry evolves.”</p>
<p>The announcement builds on the success of the first 2 GW solar module factory, and will add 4 GW more to the company’s manufacturing capacity. The new factory also follows the company’s previously announced plan to develop a 5 GW ingot and wafer manufacturing facility in Indonesia. That plant commenced construction in September 2024, and is expected to come fully online sometime this quarter.</p>
<p>Once both plants are completed, the company says it will be able to provide a full supply chain of ingots, wafers, and solar cells. Fully domestic manufacturing has become increasingly important, the company says, as supply chain issues and <a href="https://solarbuildermag.com/projects/trumps-one-big-beautiful-bill-act-reshapes-u-s-energy-landscape/">policy changes</a> continue to affect the wider solar landscape. SEG officials also say the company has been verified as a non-PFE for <a href="https://solarbuildermag.com/policy/treasury-issues-feoc-guidance-for-solar-developers-manufacturers/">FEOC compliance</a> purposes.</p>
