Solar power (also known as solar energy) is the technology of obtaining usable energy from the light of the sun. Solar energy has been used in many traditional technologies for centuries, and has come into widespread use where other power supplies are absent, such as in remote locations and in space. Large Concentrating Solar Power plants create the thermal energy equivalent to conventional fossil fuel power plants.The CSP examples above assume 30 percent energy conversion efficiency and 100 percent land use. The efficiency of solar modules as well as their degradation (loss of performance) has a direct effect on the yield of a solar plant.Hence, the solar energy to electricity conversion is more efficient. 3.2 POWER PLANT EFFICIENCY This section indicates efficiency values for converting fuels into electricity in todays average thermal power plant.Pertains to the direct conversion of light into electricity.
