ES Foundry, an American company advancing U.S. solar by onshoring crystalline solar cell production, announced a multi-year agreement to supply 300 megawatts (MWs) of high-performance, U.S.-made solar cells to Bila Solar, a domestic solar module manufacturer.
The solar cells will be made in Greenwood, South Carolina.
Officials said the strategic partnership between ES Foundry and Bila Solar highlights the growing demand for domestically produced solar technology and the ongoing shift toward onshoring critical manufacturing.
By producing their solar cells and modules entirely in the United States, both companies strengthen the domestic supply chain and advance American energy dominance, economic stability and security, the officials said.
"This agreement with Bila Solar underscores the increasing market confidence in American-made solar cells," said Ken Johnston, vice president of sales at ES Foundry.
Johnston added, "By partnering with a forward-thinking module manufacturer like Bila Solar, we're expanding access to high-efficiency solar products and driving domestic manufacturing growth. This reduces reliance on imports and reinforces the U.S. as a global leader in clean energy manufacturing."
ES Foundry's state-of-the-art solar cell manufacturing facility in South Carolina began production in early 2025, delivering high-efficiency monocrystalline bifacial PERC (Passivated Emitter and Rear Contact) solar cells.
Officials said the partnership with Bila Solar reflects the increasing demand for scalable, U.S.-produced solar technology and reinforces ES Foundry's ability to deliver at commercial volumes.
Bila Solar is a new solar panel manufacturer based in Indianapolis, Indiana. The company recently completed retrofitting a former Eli Lilly factory, and its patented ultra-lightweight solar panels are already in production.
In addition, the company announced in January that it would expand its product lines to include conventional 550W glass and aluminum frame modules, which incorporate domestically produced solar cells.
Officials said these modules can help solar developers access the ITC's 10 percent domestic content bonus credit, particularly on ground-mount projects such as fixed-tilt and carport solar applications.
Production of Bila Solar's new line of domestic cell modules will start in May.
