Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV) , or indirectly using concentrated solar power ( CSP). Of concentrated solar power systems use lenses or mirrors and tracking systems to focus a large part of the sunlight into a small beam. Photovoltaic convert light into an electric current by using the photoelectric effect.Commercial CSP plants were first developed in the 1980s. The 354 MW SEGS CSP plant is the largest solar plant in the world...
