CSP technology produces electricity by concentrating and harnessing solar thermal energy using mirrors. At a CSP installation, mirrors reflect the sun to a receiver that collects and stores the heat energy. That heat is used to power an engine or turbine that is connected to an. 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 of sunlight toward. Concentrated solar power (also known as concentrating solar power or concentrating solar-thermal power) works in a similar way conceptually. The reasons for this are obvious: The sun is an inexhaustible source for power production. And it is not only a free fuel source but also a complete emissions-free source. Steam turbine. This Amonix system in Las Vegas, US, consists of thousands of small Fresnel lenses, each focusing sunlight to ≈500x higher intensity onto a tiny, high-efficiency multi-junction solar cell. A Tesla Roadster is parked beneath for scale. The working principle of Concentrated Solar Power (CSP) is that it uses mirrors or lenses to reflect. Concentrating solar-thermal power (CSP) technologies can be used to generate electricity by converting energy from sunlight to power a turbine, but the same basic technologies can also be used to deliver heat to a variety of industrial applications, like water desalination, enhanced oil recovery.
