Premium American Polysilicon, Wafers, and Solar Cells Maximize Domestic Content, Enable U.S.-Made Module

CORNING, N.Y. & NORCROSS, Ga. & MOUNTAIN IRON, Minn., March 06, 2025--(BUSINESS WIRE)--Suniva, the largest and oldest U.S. manufacturer of high-efficiency monocrystalline silicon solar cells, and Heliene Inc., a leading U.S. solar PV module manufacturer, today announced a landmark deal with Corning Incorporated (NYSE: GLW) to provide the U.S. domestic market with the only solar module made with polysilicon, wafers and cells manufactured in the United States.

Corning is supplying the wafers and, as the majority owner of Hemlock Semiconductor (HSC), sourcing HSC's hyper-pure polysilicon for the groundbreaking initiative. Both the wafers and polysilicon are made in Michigan, and the solar cells are made in Georgia, ensuring American-made solar components of the highest quality form the foundation of the module.

The new module contains a solar cell with up to 66 percent domestic content—the highest percentage on the market—offering solar developers a significant advantage through the Investment Tax Credit domestic content bonus.

"Corning is excited to leverage our advanced manufacturing expertise to deliver top-quality solar components and secure the U.S. energy supply chain," said AB Ghosh, Corning Vice President and General Manager of Solar Technologies and Chairman and CEO of Hemlock Semiconductor.

"We are excited that this partnership brings a truly Made-in-America solution to the United States market," said Matt Card, President of Suniva. "Together, our companies offer the only solar cell in the market that provides U.S. developers maximum ITC domestic content advantage - while building a domestic supply chain that provides for American energy independence and a strong manufacturing base."

"This partnership is a significant milestone for the U.S. solar industry," said Martin Pochtaruk, CEO of Heliene. "By combining our strengths, we are able to deliver not only a high-performance module but also support the domestic economy and American job creation."
