United Solar Polysilicon Manufacturing Facility

under construction

United Solar Holding is developing the world's most advanced polysilicon manufacturing facility in the Sohar Freezone, Oman, through its subsidiary United Solar Polysilicon. The facility is designed to produce 100,000 metric tonnes of polysilicon annually, supporting around 40GW of solar module production per year. The project aims to diversify the global solar supply chain by providing a secure and large-scale alternative to the current concentration in China. The project is also expected to contribute to a broader manufacturing ecosystem in Oman, including future plans for silicon metal production, solar cell development, and a 700-MW solar power project.
