SEG Solar has announced plans to establish a 4 GW solar module manufacturing facility in Houston, US. The facility represents an investment of more than $200 million, expanding SEG’s total annual US solar module production capacity to approximately 6 GW. The facility is expected to commence operations in the third quarter of 2026. Furthermore, the expansion follows SEG’s plans for a 5 GW ingot and wafer manufacturing facility in Indonesia, strengthening its fully integrated solar supply chain across ingots, wafers, and cells.
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.
In November 2025, First Solar announced plans to set up a new facility in Gaffney, South Carolina, to complete the production process for its Series 6 Plus modules. The company plans to invest approximately $330 million in the plant, which is scheduled to begin commercial operations in the second half of 2026. The facility is expected to add 3.7 GW of manufacturing capacity.
