Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light.
Charles Fritts (1850 – 1903 [1]) was the American inventor credited with creating the first working selenium cell in 1883.. According to CleanTechnica, the world's first rooftop solar array, using Fritts' selenium cells, was installed in 1884 on a New York City rooftop. [2]
Vanguard I, the first solar-powered satellite, was launched with a 0.1 W, 100 cm 2 solar panel. 1959 - Hoffman Electronics creates a 10% efficient commercial solar cell, and introduces the use of a grid contact, reducing the cell's resistance.
It has been speculated that Cove may have invented a photovoltaic panel 40 years before Bell Labs did in 1950. [10] Sugandha Srivastav of the University of Oxford has noted that the use of fossil fuels grew significantly across the globe in those forty years, arguing that "avoiding a 40 year break in solar power’s development could have spared the world huge amounts of carbon emissions."
Usually, solar panels are given a lifespan of 25–30 years before they get decommissioned. [178] The International Renewable Energy Agency estimated that the amount of solar panel electronic waste generated in 2016 was 43,500–250,000 metric tons. This number is estimated to increase substantially by 2030, reaching an estimated waste volume ...
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 2 ]
Alexandre-Edmond Becquerel (French: [ɛdmɔ̃ bɛkʁɛl]; 24 March 1820 – 11 May 1891), [1] known as Edmond Becquerel, was a French physicist who studied the solar spectrum, magnetism, electricity and optics. In 1839, he discovered the photovoltaic effect, the operating principle of the solar cell, which he invented in the same year.

Frank Shuman (/ ˈ ʃ uː m ə n /; January 23, 1862 – April 28, 1918) was an American inventor, engineer and solar energy pioneer known for his work on solar engines, especially those that used solar energy to heat water that would ...
