A big reason for this huge gain was the Inflation Reduction Act, which set aside $369 billion for investing in clean energy manufacturing and production. It also created large tax credits for rooftop solar installation.
According to SEIA, total US solar energy capacity at the end of 2023 stood at 177 GW. If the strong pace of new solar installations continues, the United States will reach 637 GW of solar capacity by 2034. This is enough capacity to power over 100 million homes.
California currently leads the United States in terms of solar generation capacity with 39.72 GW. Texas is second with 17.24 GW, and Florida is third with 10.11 GW. Rounding out the top five are North Carolina (8.17 GW) and Arizona (6.33 GW).
