SEG Solar has announced plans to build a 4.6 GW solar module manufacturing facility in Greater Houston, Texas. The facility will increase SEG’s US solar module manufacturing capacity to 10.6 GW and will support next-generation heterojunction (HJT) solar module production. The facility’s construction is expected to be completed by March 2027 with commercial operations commencing in May 2027.
In May 2026, SEG Solar announced plans to establish a 4 GW solar module manufacturing facility in Houston, Texas. Commercial operations for the facility are expected to begin in the third quarter of 2026. The project represents an investment of more than $200 million.
In December 2025, SEG Solar announced plans to develop a 3 GW ingot and wafer manufacturing facility in Batang Regency, Indonesia. The project forms phase I of a broader 5 GW expansion plan for ingot and wafer production. The proposed manufacturing facility is expected to involve an investment of about $80 million, fully funded by SEG. Moreover, production at the plant is scheduled to begin in the third quarter of 2026.
