Solar energy available by location

Where can I find solar resource data?

Explore solar resource data via our online geospatial tools and downloadable maps and data sets. Access our tools to explore solar geospatial data for the contiguous United States and several international regions and countries.

Where can I find large-scale solar energy facilities?

All large-scale solar energy facilities can now be found on a single map thanks to a collaboration between the U.S. Geological Survey and the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. The interactive map is based on the United States Large-Scale Solar Photovoltaic Database (USPVDB) and is called the USPVDB Viewer.

Are solar photovoltaic map services free?

Map services and data downloaded from the U.S. Large-Scale Solar Photovoltaic Database are free and in the public domain.

Where can I find a large-scale solar photovoltaic database?

The United States Large-Scale Solar Photovoltaic Database can be accessed here or through the USPVDB Viewer. All large-scale solar energy facilities can now be found on a single map thanks to a collaboration between the U.S. Geological Survey and the U.S. Department of Energy’s Lawrence Berkeley National Laboratory.

How many large-scale solar facilities are in the US?

The database currently contains data for nearly 3,700 U.S. large-scale solar facilities across 47 states plus Washington, D.C. that became operational between 1986 and the end of 2021. The database contains nearly 100% of this category of facilities installed during that period.

Which state produces the most solar power?

In 2023, California accounted for the largest percentage share of total utility-scale solar electricity generation (25%), followed by Texas (17%). California accounted for nearly 40% of total generation from small-scale PV systems. Most small-scale PV systems are installed on or near buildings.
