SEG Solar, a prominent American solar manufacturer, has secured a land utilization agreement to establish a state-of-the-art 5GW vertically integrated photovoltaic (PV) manufacturing facility in Indonesia. This ambitious project, located in Batang Regency, Central Java, spans more than 40 hectares and represents a substantial investment exceeding USD 500 million.
The manufacturing plant will be developed in phases, with the initial phase targeting an annual production capacity of 5GW for solar cells and 3GW for modules. Scheduled for completion by the second quarter of 2025, the facility will focus initially on tunnel oxide passivated contact (TOPCon) technology, with potential future incorporation of heterojunction technology. Once fully operational, the plant aims to integrate the entire PV production chain from wafer manufacturing to module assembly, achieving a total annual capacity of 5GW. This comprehensive approach is designed to streamline supply chain operations and ensure the production of environmentally sustainable, traceable solar products for global markets, including the US, Europe, and Indonesia.
A spokesperson from SEG Solar emphasized that the integrated manufacturing layout is critical to meeting rigorous supply chain standards, supporting the company’s commitment to delivering clean energy solutions worldwide. The Indonesian facility will supply solar cells to SEG Solar’s global module assembly operations, including a nearly completed 2GW TOPCon module assembly plant in Texas, USA, funded with over USD 60 million and expected to begin operations this year. SEG Solar aims to achieve a combined annual module capacity of 5.5 GW across its global facilities by the end of 2024.
This announcement follows significant developments in Indonesia’s solar manufacturing sector, including Gstar’s ongoing construction of a 3GW silicon wafer plant scheduled to commence production by late 2024.
