ES Foundry Partners with Bila Solar to Supply 300 Megawatts of U.S.-Made Solar Cells for Domestic Production Expansion

ES Foundry To Supply 300 Megawatts Of U.S. Manufactured Solar Cells To Bila Solar For Expanding Domestic Module Production

ES Foundry, a prominent American company dedicated to bolstering the U.S. solar industry through domestic production of crystalline solar cells, has signed a multi-year agreement with Bila Solar, a domestic solar module manufacturer. As part of this agreement, ES Foundry will deliver 300 megawatts (MW) of high-performance solar cells made in the U.S. to Bila Solar. These solar cells will be produced at ES Foundry’s advanced manufacturing facility located in Greenwood, South Carolina.

This partnership highlights the growing demand for domestically produced solar technology and reflects a wider industry trend towards onshoring critical manufacturing processes. By keeping the entire production process within the United States, both ES Foundry and Bila Solar are actively reinforcing the domestic supply chain. Their collaboration contributes to advancing American energy independence, ensuring economic stability, and bolstering national security by minimizing reliance on imported materials.

ES Foundry’s cutting-edge solar cell manufacturing facility in South Carolina began operations in early 2025. The plant specializes in producing high-efficiency monocrystalline bifacial PERC (Passivated Emitter and Rear Contact) solar cells, recognized for their superior performance and efficiency in converting sunlight into electricity. The agreement with Bila Solar emphasizes the increasing demand for scalable, U.S.-produced solar components and demonstrates ES Foundry’s capability to deliver at commercial volumes.

Ken Johnston, Vice President of Sales at ES Foundry, 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 U.S. as a global leader in clean energy manufacturing.”

Mick McDaniel, General Manager at Bila Solar, added, “With 100% of our products manufactured in Indianapolis, Bila Solar is committed to delivering high-performance, domestically sourced solar modules. Since the U.S. Treasury published its Safe Harbor guidelines regarding the 10% domestic content bonus credit, we’ve seen greater interest in U.S.-produced modules that incorporate U.S.-made solar cells. Bila Solar is excited to be one of the first companies to offer this product in the marketplace.”

Headquartered in Indianapolis, Indiana, Bila Solar is an emerging player in the solar panel manufacturing sector. The company has recently transformed a former Eli Lilly factory into a modern solar panel production facility. Bila Solar has already initiated the production of its patented ultra-lightweight solar panels and announced an expansion of its product line to include conventional 550W glass and aluminum frame solar modules. These new modules will utilize domestically produced solar cells, further bolstering the U.S. solar manufacturing landscape.

The introduction of these domestically produced modules presents significant benefits for solar developers, particularly in qualifying for the Investment Tax Credit (ITC) bonus, which offers an additional 10% tax credit for solar projects meeting domestic content requirements. Production of the new modules at Bila Solar is set to commence in May, positioning the company as a key contributor to the growth of U.S.-made solar products.

Both ES Foundry and Bila Solar will be showcasing their commitment to strengthening U.S. solar manufacturing at the upcoming Intersolar North America & Energy Storage North America conference, scheduled for February 25-27 at the San Diego Convention Center in California. At this event, the two companies will highlight their dedication to promoting innovation in the renewable energy sector and supporting the transition towards a more sustainable and self-reliant energy future.
