What is solar energy? Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltaic, PV, cells.
The energy from the sun is produced by nuclear fusion in the suns core and travels at the speed of light to earth (186,000 miles/ second). Solar energy is a renewable source since there will be solar energy as long as the sun exists.
