SEG Solar, a leading U.S. photovoltaic module manufacturer, has announced plans to establish a 3GW ingot and wafer production facility in Batang Regency, Indonesia, the first phase of its broader 5GW expansion initiative. This investment represents a pivotal milestone in SEG’s strategy to create a fully integrated, non-FEOC supply chain that supports the U.S. solar market while advancing the SEG Indonesia PV Industrial Park’s development.
The new Indonesian facility, fully funded by SEG with an estimated investment of USD 80 million, will span approximately 50,000 square meters. Production is slated to begin in Q3 2026, strengthening SEG’s upstream manufacturing capabilities and reinforcing the resilience and scalability of its global production network.
SEG currently operates a module facility in the United States and a solar cell manufacturing facility in Indonesia, forming the foundation of its vertically integrated production platform. With the addition of the new 3GW ingot and wafer facility, SEG will establish an end-to-end manufacturing chain, from ingots and wafers to solar cells and finished modules.
Mr. Jun Zhuge, Founder and Chief Executive Officer of PT SEG Solar Manufaktur, stated: “Developing upstream ingot and wafer capacity is essential to completing SEG’s integrated manufacturing system. With complementary production capabilities in the United States and Indonesia, SEG is positioned to deliver a fully traceable and non-FEOC supply chain that meets current and upcoming requirements for the U.S. solar industry.”
The construction of SEG’s ingot and wafer facility represents a significant milestone that strengthens the company’s commitment to delivering high-quality, reliable products. Moreover, it enhances transparency and traceability across the supply chain, meeting strict origin and compliance expectations and providing the U.S. market with a stable and trusted source of photovoltaic solutions.
Founded in 2021, SEG is a leading vertically integrated PV manufacturer headquartered in Houston, Texas, U.S., and is dedicated to delivering reliable and cost-effective solar modules to the utility, commercial, and residential markets. By the end of 2024, SEG had shipped over 6 GW of solar modules worldwide and have achieved a module production capacity of 6 GW.
