The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.
Solar Energy Resources
The U.S. Department of Energy Solar Energy Technologies Office (SETO) has developed online resources to help those who want to go solar or who work with solar energy. From someone who’s looking to add solar to their roof, to someone whose job requires them to understand solar, these web resources will help everyone understand solar energy.
