The Energy Information Administration (EIA) reported that, in 2024, the United States added a record 30 gigawatts (GW) of utility-scale solar to the grid, accounting for 61% of new capacity additions to the U.S. electric grid
In theory, solar energy was used by humans as early as the 7th century B.C. when history tells us that humans used sunlight to light fires with magnifying glass materials.
The History of solar energy is an interesting, and often misinformed story. Most believe solar power is new technology, but take a look here at the history of solar energy. You''ll see it was first discovered back in 1839. So when did solar
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.
Discover the history of solar energy and the invention of solar panels. Learn about solar power in the US, debunk myths, and explore the future of renewable energy.
The United States'' journey in harnessing solar energy began with pioneering work in the late 19th century. Charles Fritts''s creation of the first functional solar cell using selenium laid the foundation for future advancements in photovoltaic (PV) technology.

Congress passed the Solar Energy Research, Development and Demonstration Act of 1974, and the federal government was committed more than ever " to make solar viable and affordable and market...
Despite the sun being billions of years old, how humans have harnessed its energy as a renewable source is relatively new! The utilization of solar energy has come a long way. Let''s start from the beginning and walk through all the vital
We started out concentrating the sun''s heat with glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. Here you can learn more about the milestones in the historical development of solar technology, century by century, and year by year. You can also glimpse the future.
When were solar panels first used? Discover the fascinating history of solar technology, from its pioneering beginnings to its current widespread applications.
The modern solar power industry in the United States was launched in the wake of the energy crisis of the late 1970s when skyrocketing oil prices motivated governments and energy companies to develop "alternative" energy technologies.
The United States'' journey in harnessing solar energy began with pioneering work in the late 19th century. Charles Fritts''s creation of the first functional solar cell using selenium laid the foundation for future advancements
To further push solar toward commercialization, Congress passed the Solar Photovoltaic Energy Research, Development, and Demonstration act of 1978 directing the
Ultimately, it would be some time before solar energy saw widespread adoption in the United States. In 1973, early solar pioneer Karl Wolfgang Boer built was what arguably the country''s first solar-powered
Ultimately, it would be some time before solar energy saw widespread adoption in the United States. In 1973, early solar pioneer Karl Wolfgang Boer built was what arguably the country''s first solar-powered building using cadmium sulfide (CdS) platelets.
With improving technology, falling costs, and federal policy support, the United States officially eclipsed one gigawatt of solar electric generating capacity in 2008.

This timeline lists the milestones in the historical development of solar technology from 1767 to 1891. Swiss scientist Horace de Saussure was credited with building the world’s first solar collector, later used by Sir John Herschel to cook food during his South Africa expedition in the 1830s.
Later that year, the Vanguard II, Explorer III, and Sputnik-3 were all launched with PV technology on board. In 1964, NASA was responsible for launching the first Nimbus spacecraft, a satellite able to run entirely on a 470-watt solar array. In 1966, NASA launched the world's first Orbiting Astronomical Observatory, powered by a one-kilowatt array.
The Vanguard 1 satellite, launched in 1958, was among the first to use solar cells and demonstrated the viability of solar power in space. The development of silicon solar cells in 1954 marked a turning point in solar technology, offering increased efficiency and broader potential applications.
The “Solar Heating and Cooling Demonstration Act of 1974” ordered the installation of solar heating and cooling units in federal buildings by 1977 to acclimate the public to the new technology.
