United Solar Starts Polysilicon Production at Oman Plant Supporting 40 GW of Solar Modules

Omani solar manufacturing company United Solar Holding has begun production at its polysilicon manufacturing facility in Oman, a project that is expected to support the production of up to 40 GW of solar modules annually once fully ramped up. The plant has a planned polysilicon output capacity of 100,000 metric tons per year.

The start of production was announced by China-based Shuangliang Hydrogen, which said it supplied four green power intelligent hydrogen production systems to the facility. The company stated that all supplied equipment achieved successful first-time start-up, supporting the commissioning of the project.

Middle East’s Largest Polysilicon Facility

The factory is located in the Sohar Freezone and is described as the Middle East’s largest polysilicon manufacturing facility. Once fully operational, the plant is expected to support the production of up to 40 GW of solar modules annually, playing a key role in strengthening the region’s photovoltaic value chain.

Shuangliang Hydrogen said the project represents a new connection point linking PV supply chains across Europe, Africa and Asia.

Over USD 900 Million in Financing

In January 2026, United Solar secured more than USD 900 million in financing to complete funding for the facility. The final package included USD 480 million in term debt from the International Finance Corporation (IFC) and its partner institutions.

The IFC-backed financing comprised USD 200 million from IFC’s own account, a USD 50 million long-term debt facility from the OPEC Fund for International Development, and USD 230 million committed by Abu Dhabi Commercial Bank, Al Ahli Bank of Kuwait, Commercial Bank of Dubai and First Abu Dhabi Bank.

In addition, United Solar received more than USD 400 million in term debt and working capital facilities from local lenders, including Oman Arab Bank, which signed a USD 220 million financing agreement in December.

Sovereign Wealth Fund Backing

United Solar’s largest shareholder is Future Fund Oman, part of the Oman Investment Authority. The fund initially invested around USD 156 million in the project, with its total exposure increasing to nearly USD 260 million.

The financing followed earlier support of USD 250 million from the World Bank in 2025.

Construction of the polysilicon plant began in March 2024. With operations now starting this quarter, the project marks the completion of a nearly two-year construction period.
