The solar cells will be produced at ES Foundry’s facility in Greenwood, South Carolina.
ES Foundry vice-president of sales Ken Johnston stated: “This agreement with Bila Solar underscores the increasing market confidence in American-made solar cells.
“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 US as a global leader in clean energy manufacturing.”
ES Foundry’s facility, operational since early 2025, produces high-efficiency monocrystalline bifacial PERC [passivated emitter and rear contact] solar cells, reflecting the growing demand for scaleable, US-produced solar tech.
Bila Solar, a solar panel manufacturer based in Indianapolis, Indiana, has retrofitted a former Eli Lilly factory to produce its patented ultra-lightweight solar panels.
In January 2025, the company announced plans to extend its product lines to include conventional 550W glass and aluminium frame modules with domestically produced solar cells.
The new modules will enable solar developers to access the investment tax credit’s 10% domestic content bonus credit, especially for ground-mount projects such as fixed-tilt and carport solar applications.
Production of Bila Solar’s new line of domestic cell modules is set to begin in May 2025.
Bila Solar general manager Mick McDaniel stated: “With 100% of our products manufactured in Indianapolis, Bila Solar is committed to delivering high-performance, domestically sourced solar modules.
“Ever since the US Treasury published its Safe Harbor guidelines regarding the 10% domestic content bonus credit, we’ve seen greater interest in a US-produced module that incorporates a US-made solar cell. Bila Solar is excited to be one of the first companies to offer this product into the marketplace.”
