In 2050, we project that total U.S. solar capacity, which includes both utility-scale solar and rooftop solar in the commercial and residential sectors, could range from 532 gigawatts (GW) to 1,399 GW. In our Annual Energy Outlook 2023 (AEO2023), we present 16 scenarios, or cases, that project long-term energy trends in the United States through 2050.
