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.
This new 4.6 GW facility announcement comes right after its earlier one in May 2026, where it 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.
REGlobal’s Views: The tightening of solar imports, changing geopolitics and ensuring supply chain risks for solar projects have led to an uptick in expansion of solar manufacturing facilities across the US, as evident from the back to back announcements by SEG Solar regarding the development of new factories. The US continues to be a top solar market witnessing massive investments despite policy flux and solar plus storage projects are especially gaining traction in the wake of increasing energy prices.
