The United States has reached a historic milestone, surpassing 50 gigawatts (GW) of domestic solar module production capacity. At full capacity, these factories can supply the nation’s entire solar demand, marking a significant step toward energy independence.
This achievement strengthens the U.S.-based solar supply chain, reducing reliance on foreign sources while supporting American jobs.
According to the Solar Energy Industries Association’s (SEIA) Supply Chain Dashboard, companies have announced plans for 56 GW of new U.S. solar cell production, along with 24 GW of wafer and 13 GW of ingot production. Additionally, solar tracker manufacturing capacity now exceeds 80 GW, reinforcing the nation’s growing clean energy infrastructure. “Reaching 50 GW of domestic solar manufacturing capacity is a testament to what we can achieve with smart, business-friendly public policies in place,” said SEIA president and CEO Abigail Ross Hopper. “The U.S. is now the third largest module producer in the world because of these policy actions. This milestone not only marks progress for the solar industry but reinforces the essential role energy policies play in building up the domestic manufacturing industry that American workers and their families rely on.”
