United Solar Closes $1.6 Billion Funding for Oman Polysilicon Plant

The Sohar-based plant, which launched operations in January 2026, is currently ramping up toward a 100,000-ton annual production capacity. As a FEOC-compliant producer, United Solar offers high-purity, fully traceable material essential for companies navigating strict international supply chain regulations. The IFC’s involvement accounts for over 30% of the total capital mobilized, serving as a significant endorsement of the project’s governance and environmental standards.

Backed by the Oman Investment Authority, the facility aims to support the production of 40 gigawatts of solar modules annually. Beyond its industrial output, the project is projected to offset 8.8 million tons of carbon emissions each year while creating nearly 3,000 jobs. For global manufacturers, this operational capacity provides a stable, diversified alternative to existing supply routes, meeting the growing demand for transparent and sustainable energy components.
