Suniva completed an $835 million debt and equity financing round to fund its second major domestic solar cell manufacturing plant in Laurens County, South Carolina, the company said on Tuesday.
The project will add 4.5 gigawatts of capacity, pushing the company's total production capability to 5.5 GW when fully ramped in 2028, the company stated.
Goldman Sachs Alternatives, I Squared Capital, and Lion Point Capital backed the funding round, it noted.
The new South Carolina plant is scheduled to come online in late 2027, complementing Suniva's existing 1GW facility in Norcross, Georgia.
The expansion aims to address domestic supply chain vulnerabilities by providing high-efficiency monocrystalline silicon cells to the US solar market, backed by long-term offtake agreements, it noted.
This follows Suniva's definitive reverse merger agreement with Sunation Energy (SUNE), announced in June 2026.
