SEG Solar has announced plans to develop its third U.S. manufacturing facility in Greater Houston, Texas, the new 4.6GW facility expected to bring the company’s planned annual U.S. module manufacturing capacity to 10.6GW, further strengthening its position as one of the largest domestic solar module manufacturers and advancing its long-term localization strategy.
As part of its continued U.S. expansion, SEG has signed an agreement with a local construction company to develop the new facility on a site spanning approximately 1.15 million square feet, to include a factory and a warehouse. The announcement comes ahead of the opening of the company’s second 4GW factory, scheduled for August. Construction of the third facility is projected to be completed by March 2027, with commercial production expected to begin two months later.
The new facility is being planned to support SEG’s transition toward next-generation HJT technology, enabling high-efficiency module production aligned with the evolving needs of the U.S. market. The facility is also designed to support FEOC-compliant production through strengthened supply chain traceability, material control and compliance management.
To further support its U.S. manufacturing expansion and strengthen resilience amid evolving trade and supply chain policies, SEG has initiated planning for an ingot and wafer facility in Indonesia. This upstream integration is intended to secure critical components and enhance the resilience of the company’s global supply chain. It is also evaluating potential U.S. sites for a dedicated HJT cell manufacturing facility, further advancing its strategy to localize key manufacturing processes and strengthen control over next-generation solar technologies.
