Solar power uses the suns radiant light energy to produce heat, light and power in the form of electricity, to power our world making solar power a true renewable energy resource. The solar radiation reaching the earth’s surface equals about 1000 watts per square metre in clear conditions when the sun is near the zenith making it inexhaustible and locally available everywhere on the earth. One of the best uses of solar power is in using photovoltaics to generate electricity and thermal panels to heat water were concentrated solar power uses the immense heat provided by solar irradiation concentrated on a small area.
