Abstract: The sun is the world’s sole source of energy. In fact, all of the energy being used on the earth today is driven from solar energy. Because of the increase in world energy demand and the threat of global warming; there is a pressing need for the development of reliable, cost-effective sources of renewable energy. Renewable energy sources include indirect solar energy such as hydro, wind and direct solar energy conversion through thermal receivers or photovoltaic. This paper discusses the parameters that affects on the cell temperature under concentration. Comparison between fixed modules and solar cells operating under concentration to get the optimum solution. By increasing the concentration factor one minimizes the area of the cell .System uses special cell (Fresnel lens and multilayer cells).This cell has large efficiency and bear high temperature. The economic studies are necessary to calculate the cost of 1kwh for each case.
