ES Foundry, a U.S. crystalline solar cell manufacturer, will present its Foreign Entity of Concern (FEOC)-compliant products at RE+ 2025 in Las Vegas. The South Carolina-based firm will also have its chief executive participate in two conference panels to highlight pathways to compliance and domestic supply.
The company said it is in full production at its Greenwood, South Carolina facility, supplying FEOC-compliant cells to developers, asset owners, investors, and capital partners. These products qualify projects for current incentives, including the domestic content bonus. “FEOC restrictions are fundamentally reshaping how projects get financed and built,” said Ken Johnston, ES Foundry’s vice president of sales. “Without compliant cells, developers risk losing incentives, and investors face unacceptable exposure.”
The U.S. Treasury and Internal Revenue Service recently clarified that projects using components tied to foreign entities of concern may lose both core tax credits and domestic content bonuses. With limited domestic manufacturing capacity, ES Foundry said its facility will serve as a transparent supply source, sourcing materials from verified, compliant suppliers by 2026. CEO Alex Zhu is scheduled to speak at RE+ panels on FEOC compliance, bankability, and domestic content requirements.
