Solar power, the harnessing of the sun''s energy for human use, has a long and fascinating history. From ancient civilizations that used sunlight for practical purposes to the development of sophisticated photovoltaic (PV) technology,
Explore the fascinating journey of solar energy from its ancient beginnings to its modern applications and future potential. Discover how solar
Energy from the sun The sun has produced energy for billions of years and is the ultimate source for all of the energy sources and fuels that we use. People have used the sun''s rays (solar radiation) for thousands of years for warmth and to dry meat, fruit, and grains. Over time, people developed technologies to collect solar energy for heat and to convert it into electricity.
Solar energy as a resource for human beings has been around for a very long time—but as an industry, it''s a relative newcomer. Find out more about the history of solar energy and its recent surge in our latest blog.
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.
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.
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.
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.
Ancient civilizations effectively harnessed solar energy through innovative methods. They used solar architecture and agricultural practices to meet their daily needs, showcasing early solar building techniques. Key ancient solar practices included: Using structures designed to capture sunlight for warmth and crop growth.
The 1970s oil crises fueled interest in substitute energy, spurring solar research and development. By the 1980s and 90s, commercial solar panels became more accessible. Improvements in efficiency and reductions in cost made this possible. These advancements paved the way for widespread adoption.
