less than 0.5% of what is theoretically available from sunlight. 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 (MWth) of solar water heating, 762 MWth of pool heating, and 21 MWth of solar space heating and cooling.

A 2012 report from the National Renewable Energy Laboratory (NREL) described technically available renewable energy resources for each state and estimated that urban utility scale photovoltaics could supply 2,232 TWh/year, rural utility scale PV 280,613 TWh/year, rooftop PV 818 TWh/year, and CSP 116,146 TWh/year, for a total of almost 400,000 TWh/year, 100 times current consumption of 3,856 TWh in 2011. A report by research and publishing firm Clean Edge and the nonprofit Co-op America found that solar power's contribution could grow to 10% of the nation's power needs by 2025, with nearly 2% of the nation's electricity coming from concentrating solar power systems, while solar photovoltaic systems would provide more than 8% of the nation's electricity.

A 1998 report by the United States Department of Energy found available domestic solar energy (including biomass) technically accessible regardless of cost amounted to 586,687 Quadrillion BTUs (Quads); 95% of this was biomass.

Coal represented the second largest resource, a distant 38,147 Quads.

Solar Energy Industries Association and GTM Research found that the amount of new solar electric capacity increased in 2012 by 76 percent from 2011, raising the United States’ market share of the world’s installations above 10 percent, up from roughly 5 to 7 percent in the last seven years. Located in Philadelphia, the solar water pump station was capable of pumping 3000 gallons an hour (25 hp) Solar One, the first pilot solar power tower design was completed in 1981.

The parabolic trough Solar Energy Generating Systems opened its first unit in 1984, the first major solar thermal plant in the world.

In the twelve months through November 2017, utility scale and distributed solar power generated 52.1 terawatt-hours (TWh), 1.29% of total U. The United States conducted much early research in photovoltaics and concentrated solar power.

It is among the top countries in the world in electricity generated by the Sun and several of the world's largest utility-scale installations are located in the desert Southwest.

In November 2016 the company reduced the workforce in the Perrysburg plant by 20% as part of a worldwide restructuring.

As a result, the report projects that solar power will reach cost parity with conventional power sources in many U. According to a study by the Solar Energy Industries Association and GTM Research, 878 megawatts (MW) of photovoltaic (PV) capacity and 78 MW of concentrating solar power (CSP) were installed in the U. This was double the 435 MW installed in 2009 around the U. According to a 2011 survey conducted by independent polling firm Kelton Research, nine out of 10 Americans support the use and development of solar technology.

Eight out of 10 respondents indicated that "the federal government should support solar manufacturing in the United States and should give federal subsidies for solar energy".

A view of solar panels installed in 2011 on the roof of Space and Naval Warfare Systems Command Headquarters, San Diego.

The rooftop photovoltaic installation supports the Department of Defense's goal of increasing renewable energy sources to 25 percent of all energy consumed by the year 2025.

Predictions of how much solar power was economically feasible to collect amounted to 352 quads, compared with 5,266 quads from coal.
