SEG Solar Begins Production of HJT Modules in Texas
SEG Solar has started production at its new Tomball facility in Texas for heterojunction (HJT) solar modules. This marks the beginning of commercial-scale output from SEG's second U.S. plant, increasing their North American module capacity to 6GW annually. The $200 million investment spans over 500,000 square feet and is equipped with four production lines focused on SIERRA N series HJT modules using advanced manufacturing techniques like AI-enabled inspection and automation. The Tomball facility uses low-temperature soldering and precision butyl sealant application to improve module durability and energy output. SEG Solar's CEO emphasized the company’s commitment to U.S.-based manufacturing amid new policy challenges, aiming for a fully traceable domestic supply chain. The firm also plans another 4.6GW HJT plant set to open in 2027, with additional cell production expected by 2028. HJT technology is known for higher bifaciality and lower degradation rates compared to traditional modules, potentially offering better long-term energy yields.
