6 天之前· An official website of the United States government. Here''s how you know. Here''s how you know. Solar owners can reduce their energy bills with savings that will accrue for the lifetime of the system. Community solar can provide savings for those who rent their homes or whose roofs aren''t suitable for solar panels.
Solar generation was 3% of U.S. electricity in 2020, but we project
According to our Electric Power Annual, solar power accounted for 3% of U.S. electricity generation from all sources in 2020. In our Short-Term Energy Outlook, we forecast that solar will account for 4% of U.S. electricity generation in 2021 and 5% in

A complete list of incentives is maintained at the Database of State Incentives for Renewable Energy (DSIRE). Most solar power systems are grid connected and use net metering laws to receive compensation for electricity that is not consumed on site and exported to the grid. New Jersey leads the nation with the least restrictive net metering law, and California leads in total number of home
U.S. Solar Photovoltaic Manufacturing
Since 2021, all CS PV panel assembly in the United States has relied on imported cells. Domestic panel assembly supplies a relatively small proportion of domestic demand for solar panels. The domestic solar manufacturing industry employed around 31,000 workers in 2020, accounting for about 15% of total solar-industry employment.
The State of the Solar Industry
residential PV systems in the United States. – 3.3% of households own or lease a PV system (or 5.3% of households living in single-family detached structures). – Top states for share of solar on single-family detached structures: •Hawaii: 35% •California: 23% •Arizona: 14%
The U.S. Large-Scale Solar Photovoltaic Database
The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U.S. ground-mounted photovoltaic (PV) facilities with capacity of 1 megawatt or more. It includes corresponding PV facility information, including panel type, site type, and initial year of operation.
Solar power in the United States
The SEIA report tallies all types of solar energy, and in 2007 the United States installed 342 MW of solar photovoltaic (PV) electric power, 139 thermal megawatts (MW th) of solar water heating, 762 MW th of pool heating, and 21 MW th of solar space heating and cooling.
How Does Solar Work?
Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
