We empower developers and investors to act with confidence in a complex and rapidly changing market. By onshoring crystalline solar cell production and maintaining a transparent fully FEOC-compliant supply chain, we provide the stability, credibility and clarity our partners need to plan for the future.
Our solar cells are manufactured in South Carolina with zero FEOC ties — no ownership, IP, executives or funding. Whether you’re qualifying under current domestic content rules or preparing for higher thresholds in 2026 and beyond, ES Foundry is the strategic partner you can rely on.
Building a resilient U.S. solar industry requires more than manufacturing capacity — it requires meaningful manufacturing capability. ES Foundry performs the core semiconductor processes — including diffusion, P/N junction formation, passivation and metallization — that define solar cell manufacturing, investing in the technology, workforce and expertise needed to strengthen America’s long-term energy future.
ES Foundry was founded with a vision to revive high-quality PV cell manufacturing in America and address the growing demand for domestically produced solar components. Our founders and leadership team, industry veterans with accumulated experience of 40GW+ of module sales and 30GW+ of manufacturing operational expansion, recognize that high-performance photovoltaic (PV) solar cells are a crucial component of solar deployment and play a vital role in domestic content requirements. They created ES Foundry to bring solar cell manufacturing back to the U.S. and to empower developers and project owners to capitalize on the utilization of IRS notice 2025-08 safe harbor tables for the Federal Investment Tax Credit (ITC).
With our state-of-the-art manufacturing facility in Greenwood, South Carolina, the company is on track to become the country’s largest manufacturer of silicon-based PV cells.
At the heart of our work is a commitment to delivering high-quality, American-made solar cells to build a sustainable energy future locally and nationally.
