What does this milestone mean?

    • There is enough solar installed in the United States to power roughly 50 million households, and by 2034, there will be enough solar capacity to power 100 million homes.

    • In 2025, a new solar project was installed every 59 seconds, and solar and storage combined to provide 79% of all new energy capacity added to the U.S. grid.

    • Current projections show that this momentum will continue. Every year from now through 2030, the solar industry is expected to install an additional 40 GW of capacity.

Residential Solar

  • 97% of all solar installations in the United States are on residential rooftops.
  • By 2030, there are expected to be over eight million residential solar systems in the U.S.
  • Today, 9% of homes in the U.S. have solar. By 2030, this number will grow to 11% of U.S. homes.
  • Today, there are over 46 GW of residential solar installed in the United States.

 

Energy Storage

  • Serving as a natural partner to solar is energy storage, which now has enough capacity in one charge to deploy power to 5.3 million American homes for a day. That’s more than the number of homes in New York City and Chicago combined.
  • A growing number of residential solar adopters are choosing to install batteries as well, allowing them to keep their lights on even if the grid goes down. In the first three months of 2026, 45% of new residential solar installations included a residential battery.

 

Solar in the States

  • Between 2020 and today, the number of states and territories with over 100,000 installations more than doubled from 6 to 15.
  • Over the same time frame, the number of states with over one gigawatt of solar capacity doubled from 18 to 39.
  • In 2025, the top 10 states for solar installations touched both the Pacific and Atlantic Oceans, America’s northern and southern borders, and three of the five Great Lakes.
  • America has enough solar installations to cover every residential rooftop in New York and New Jersey.
