From Charles Fritts'' invention of the first solar module in 1883 to today''s cutting-edge perovskite cells and floating solar farms, solar power has evolved into one of the most important solutions for a sustainable future.
From the earliest days of solar-powered satellites to modern rooftop arrays and utility-scale solar farms, this is the complete history of solar energy—and a look at its exciting potential in the years to come. The story of solar energy begins in 1839 with the work of French physicist Edmond Becquerel.
In the 7th century B.C., humans discovered that sunlight could be concentrated using a magnifying glass to create fire. This marked one of the earliest instances of humans manipulating solar energy for a specific purpose.
Some of the earliest uses of solar technology were actually in outer space, where solar was used to power satellites. In 1958, the Vanguard I satellite used a tiny one-watt panel to power its radios. Later that year, the Vanguard II, Explorer III, and Sputnik-3 were all launched with PV technology on board.
Although solar panel production became feasible in the 1960s and 1970s. Technology was still too expensive for most people at the time. To lower the price of solar energy, researchers kept working on new technologies. The first P-N junction cell was created after semiconductors gained popularity.
In recent years, advancements in solar panels and solar cells that convert sunlight into electricity have transformed the landscape of solar technology. These advancements have significantly enhanced the solar market and increased accessibility to solar energy, driven by companies such as Tesla.
As NASA pushed further out into the solar system in the 1970s, photovoltaics became the standard power system for its spacecraft and remains so today. Back on Earth, solar energy technology continued to advance gradually through the mid-20th century but remained uncompetitive with cheap, readily available fossil fuels.
