SEG Solar has 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. The site will cover nearly 50,000 square metres. Moreover, production at the plant is scheduled to begin in the third quarter of 2026.

This project is part of the company’s strategy to strengthen its upstream manufacturing capacity and advance the establishment of an SEG PV industrial park in Indonesia. SEG currently operates a photovoltaic module manufacturing facility in US and a solar cell manufacturing unit in Indonesia. With the addition of the planned ingot and wafer facility, the manufacturing chain will extend across all major stages, from ingots and wafers to solar cells and finished photovoltaic modules.

SEG Solar is a vertically integrated solar manufacturing company, founded in 2021 and headquartered in Houston, Texas. The company caters to utility-scale, commercial, and residential markets. The company has a module production capacity of 6 GW, as of 2024.
