The United States installed a record-breaking 50 gigawatts (GW) of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades.
According to the U.S. Solar Market Insight 2024 Year in Review report released recently by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, solar and storage account for 84 percent of all new electric generating capacity added to the grid last year.
In addition to historic deployment, surging U.S. solar manufacturing emerged as a landmark economic story in 2024. Domestic solar module production tripled last year, and at full capacity, U.S. factories can now produce enough to meet nearly all demand for solar panels in the United States. Solar cell manufacturing also resumed in 2024, strengthening America’s energy supply chain and cementing its place as a solar powerhouse.
“Solar and storage can be built faster and more affordably than any other technology, ensuring the United States has the power needed to compete in the global economy and meet rising electricity demand,” said SEIA president and CEO Abigail Ross Hopper. “America’s solar and storage industry set historic deployment and manufacturing records in 2024, creating jobs and driving economic growth. It’s critical that lawmakers continue to support an ‘all of the above’ energy strategy that fosters the growth of American energy sources like solar and storage.”
