The History of Solar
Solar panels have been constantly progressing over the past 200 years and are finally taking over as the most efficient source of energy.
1839: Edmond Becquerel discovered the photovoltaic effect.
1873: Willoughby Smith discovered selenium is a photoconductor.
1876: William Grylls Adams and Richard Evans Day linked the photovoltaic principle to selenium. Generated electricity when exposed to sunlight.
1883: Charles Fritz created the first working selenium solar cell.
1905: Albert Einstein studied how the photoelectric effect could carry energy. Publicity like this generated more attention as well as an acceptance for solar power on a broader scale.
1954: Bell Labs, Daryl Chapin, Calvin Fuller, and Gerald Pearson, created the first solar cell using silicon instead of selenium, which was more practical and efficient.
1958: Space age, Vanguard I satellite, Vanguard II, Explorer III, and Sputnik-3 used solar panels.
1964: NASA launched the Nimbus, who’s only source of power was its 470-watt photovoltaic solar panel array.
1970: Oil shortage showed US dependency on foreign resources. During this time, president Jimmy Carter installed 32 solar panels on the west wing of the White House.
2006: The Solar Investment Tax Credit (ITC) was established. The ITC encouraged the U.S. solar industry to increase by more than 10,000%.
2008: Barrack Obama removed the ITC cap and opened the ITC to all project costs
2016: The US installed 1 million solar units
