"The company’s Cartersville, Georgia, factory is the largest of its kind in the nation — and it just started producing the key solar panel component."

"Qcells has officially begun commercial production of silicon solar cells at its factory in Cartersville, Georgia, the company said Tuesday. That factory is the largest of its kind in the country — and a long-awaited boost to the U.S. solar supply chain.

For five years straight, the U.S. power sector has built more solar farms than any other kind of power plant. In 2022, the Biden administration crafted industrial policy to ensure as many of those solar panels as possible were made in America. Previously, the U.S. solar manufacturing base had withered in the face of stiff competition from China — but the industrial revival effort worked. In just a few years, the U.S. has opened up enough factories to assemble nearly 70 gigawatts of finished solar panels, according to the Solar Energy Industries Association.

That’s well beyond what the U.S. installs in a year, but production of the cell — the high-value component that converts sunlight into electricity — has lagged far behind.

Previously, just three other companies made the component in the U.S.: Suniva can produce 1 gigawatt at its cell factory in Georgia, and ES Foundry and Silfab each can make 1 gigawatt in South Carolina. In a few months, Qcells will be able to manufacture 3.3 gigawatts at its cell factory, which would more than double the current operational U.S. solar-cell capacity."
