Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination.Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. Renewable energy is energy whose source never runs out. This electromagnetic radiation majorly includes infrared rays, visible light, and ultraviolet rays. The storage of heat for use at night or on cloudy days is commonly accomplished by using insulated tanks to store the water heated during sunny periods. Solar energy definition, energy derived from the sun in the form of solar radiation. In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil fuels coal, petroleum, and natural gas.

The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by Earth, but its intensity at Earth’s surface is actually quite low. The most widely used flat-plate collectors consist of a blackened metal plate, covered with one or two sheets of glass, that is heated by the sunlight falling on it. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs. The heat may be used directly, or it may be transferred to another medium for storage. Solar energy is energy in the form of light, produced by the Sun. This is essentially because of the enormous radial spreading of radiation from the distant Sun.
