New 3.7 GW U.S. Solar Manufacturing Facility

Last Updated: Oct 31, 2025 by Eugene Frank

. The facility will begin operations at the end of 2026 and ramp up through the first half of 2027. Other than increasing the U.S.’s self-reliance when it comes to the manufacturing of solar modules, the 3.7 GW facility also supports First Solar’s expansion efforts backed by around US$ 4.5 billion. The maker also expects to reach 14 GW of annual U.S. manufacturing capacity by 2026. The company‘s solar manufacturing facility, in Lake Township, Ohio also continues expansion as First Solar expects total Ohio capacity to surpass 7 GW by end 2025. This will feature the Lake Township facility, Perrysburg’s 2.6 GW facility and an additional 1.1 GW in expansions.

Outlook on the 3.7 GW U.S. Manufacturing Facility by First Solar

Site selection, construction timeline and operational execution are all also important to First Solar’s manufacturing facility in the U.S. Additionally, with growth of the U.S. solar manufacturing landscape, this facility may also attract investments in other module technologies, alongside recycling and circular economy capabilities as well.

First Solar and U.S. PV Modules Manufacturing Landscape

The new 3.7 GW facility is in all words First Solar increasing the U.S.’smanufacturing capabilities. It also comes at a time when contentious policies on climate change and domestic supply chain security are talk of the town.

With solar module tariffs, tax credits such as the 45X assembly credit and increasing demand for renewable energy infrastructure globally, First Solar continues to make bets on manufacturing growth while focusing on regulatory tailwinds that seem to matter.
