Solar energy history
- May 10, 2018 -

According to records, mankind has used solar energy for more than 3,000 years. The use of solar energy as an energy source and power is only 300 years old. It is a matter of recent years that solar energy is truly used as a "resource that is urgently needed in the near future" and "the foundation of future energy structure." Since the 1970s, solar energy technology has grown by leaps and bounds, and the use of solar energy is changing with each passing day. The history of solar energy use in modern times can be calculated from the invention of the first solar-powered engine by the French engineer Solomon De Cox in 1615. The invention is a machine that uses solar energy to heat air to make it expand and work to pump water. From 1615 to 1900, the world developed more than one solar power plant and some other solar power plants. These power devices adopt almost all of the light collection methods to collect sunlight. The power of the engine is not large. The working medium is mainly water vapor, which is expensive and practically insignificant. Most of them are researched and manufactured by solar enthusiasts. In the 100 years of the 20th century, the history of solar energy technology development can be roughly divided into seven stages.
