Concentrated solar power (CSP), also called concentrating solar power or concentrated solar thermal, involves systems that collect solar heat for multiple purposes like cooking, desalination, or the generation of electric solar power, by using mirrors to concentrate a large area. Concentrated solar power (CSP), also called concentrating solar power or concentrated solar thermal, involves systems that collect solar heat for multiple purposes like cooking, desalination, or the generation of electric solar power, by using mirrors to concentrate a large area. A solar power tower at Crescent Dunes Solar Energy Project concentrating light via 10,000 mirrored heliostats, occupying an area of 13 million sq ft (1. A Tesla Roadster is parked beneath for scale. Concentrator photovoltaics (CPV), also called concentrating. All concentrating solar power (CSP) technologies use a mirror configuration to concentrate the sun's light energy onto a receiver and convert it into heat. The heat can then be used to create steam to drive a turbine to produce electrical power or used as industrial process heat. The energy from the concentrated sunlight heats a high temperature fluid in the receiver.
