SEG Solar Expands US PV Output With Tomball #1

• SEG Solar opens Tomball #1, a 4GW U.S. solar module plant near Houston—$200M investment, up to 800 jobs, and tech-ready for HJT upgrades—boosting capacity to 10.6GW.

SEG Solar inaugurated its second U.S. photovoltaic module plant, Tomball #1, in the Greater Houston area of Texas. The facility has 4 gigawatts of annual manufacturing capacity and covers nearly 500,000 square feet. SEG Solar said it has invested more than $200 million and expects up to 800 jobs. The plant was officially opened Aug. 7, 2026, with commercial operations scheduled for the third quarter. Designed for future upgrades, it can integrate new manufacturing technologies, including heterojunction or HJT, to improve quality, traceability and delivery speed.

With Tomball #1 online, SEG Solar’s total U.S. module capacity rises to 6 GW per year, alongside its existing Houston plant with 2 GW capacity. The company is also building a third Greater Houston factory aimed at 4.6 GW annual production across about 1.15 million square feet. Construction is expected to finish in March 2027, with commercial output set to start in May 2027. Once operational, SEG Solar expects combined U.S. capacity of about 10.6 GW, as part of its localization strategy.

How will SEG Solar’s Tomball #1 expansion boost US PV manufacturing capacity and jobs?

• Adds 4 GW/year of U.S. photovoltaic (PV) module production by bringing Tomball #1 online in Greater Houston, directly increasing domestic supply of components needed for U.S. solar projects.
  
• Raises SEG Solar’s U.S. manufacturing footprint to 6 GW/year (Tomball #1 plus the existing Houston plant), which can reduce reliance on imported modules and help stabilize delivery schedules for downstream developers and EPCs.
  
• Strengthens “local content” and supply-chain compliance by enabling more U.S.-assembled module volume for markets where domestic manufacturing requirements and procurement preferences matter.
  
• Improves the overall resilience of U.S. PV manufacturing by expanding capacity in a major U.S. solar supply hub (Texas), making it easier for suppliers and workforce ecosystems to scale with demand.
• Creates a larger pipeline of skilled manufacturing employment in the Houston area (SEG Solar expects up to 800 jobs linked to the Tomball #1 project), including roles in production operations, technicians, quality assurance, logistics, and engineering support.
  
• Supports additional indirect jobs beyond the factory floor by increasing demand for local services such as equipment maintenance, cleanroom and industrial utilities, transport/warehousing, and professional services tied to plant operations.
  
• Drives longer-term job growth potential through future technology upgrades: Tomball #1 is designed to accommodate newer cell/module processes (including next-generation device formats), which can require additional training, process engineering, and production-line enhancements.
  
• Enhances U.S. PV manufacturing competitiveness by enabling faster adaptation to evolving module designs and performance requirements, supporting higher-quality output and reducing time-to-qualification for new module variants.
  
• Provides scale that helps attract suppliers and consolidates the regional manufacturing cluster, which can lower procurement friction for materials, subcomponents, and testing services used throughout module production.
• Positions SEG Solar to expand further in Greater Houston (with a third factory planned for additional multi-gigawatt output), meaning Tomball #1 serves as an immediate capacity step while also building momentum for subsequent hiring and operational scaling.
