The sun is giant ball of energy. In reference to the earth is giant ball of solar energy. Solar power is the utilization of the sun's natural energy as a source of electricity. It uses the solar energy from the sun and converts into electricity via photovoltaic cells which are usually made out of silicon.
Capturing this energy has been around for some time. Newer uses are developed often but few are implemented due to the high cost of material and manufacturing. None the less company's engineers, scientist are looking for more efficient ways to continue use of solar energy.
