ES Foundry is revolutionizing the U.S. solar industry by onshoring the production of high-quality crystalline PV solar cells. Based in Greenwood, South Carolina, the company delivers reliable, efficient and cost-competitive solar cells.
Legal risk is project risk. The patent landscape for next-gen tech remains unstable, defined by split rulings and pending appeals. While others navigate litigation, ES Foundry is shipping IP-secure, U.S.-made PERC cells. Build with surety. solarbuildermag.com/news/canadia...

The ES Foundry team is at RE+ Northeast!

If you’re in Boston this week, stop by Booth 509 to meet the team and talk through FEOC-compliant, U.S.-made solar cell supply and what it means for near- and mid-term project planning.

We’re here, available and ready to connect.

Jan. 1 has passed. FEOC compliance is now a license to operate. Ambiguity is a liability.
ES Foundry offers clarity: 100% U.S-made cells. Zero FEOC ownership, debt or IP. Secured non-FEOC wafer supply.

Not all "domestic" cells are truly FEOC-compliant. Ours are.

➡️ Zero FEOC ownership
➡️ Zero FEOC debt or IP
➡️ 100% U.S.-made in South Carolina

Build with certainty. Contact our team: Sales@ESFoundryCorp.com
