A spokesperson at SEG Solar told PV Tech the primary focus would be on tunnel oxide passivated contact (TOPCon) technology for the plant in Indonesia, and it might consider heterojunction in the future.
Once fully operational, the project’s total capacity will be 5GW of annual nameplate production capacity from wafers to modules. The vertically integrated plant will be located in the Batang Regency in the Central Java province.
Investment in the solar manufacturing plant will exceed US$500 million and cover over 40 hectares of land.
“Integrated layout across the entire industry chain is crucial for SEG to adhere to legally compliant supply chain standards. Through upstream and downstream coordination, SEG ensures the provision of clean, traceable green products for the markets in the United States, Europe, and Indonesia, thereby facilitating the global transition towards green, low-carbon energy,” said Jun Zhuge, founder and COO of SEG Solar.
Cells produced at the Indonesian plant will supply the company’s global module assembly plant in the US. The company has plants in China, Thailand and the US which is nearly operational.
In its home-country, the company is currently building a 2GW tunnel oxide passivated contact (TOPCon) module assembly plant in Texas which is expected to be operational this year. Last year, SEG Solar completed funding for the module assembly plant with an investment of over US$60 million. The plant is currently on its equipment installation and commissioning phase, a SEG Solar spokesperson told PV Tech.
By the end of the year, the solar PV manufacturer aims to reach an annual nameplate capacity of 5.5GW of modules across its plants.
This is the latest manufacturing development in Indonesia where Singapore-headquartered PV manufacturer Gstar recently started construction on a 3GW silicon wafer plant. The plant is expected to start production by the end of 2024.
Updated on 17 May to add the technology used in Indonesia and update the status of the US module assembly plant.
