Solar power is a form of energy conversion in which sunlight is used to generate electricity. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. Below, you can find resources and information on the. . Solar energy is any type of energy generated by the sun. Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines. Both are generated through the use of solar panels, which range in size from residential rooftops to 'solar farms' stretching over acres of rural. .
