Concentrated solar power (CSP) is a collector solar power plant system. It uses mirrors or lenses, using optical principles, driveing with single or dual axis tracker to concentrate a large area of sunlight into a relatively small light collection area, so that solar energy is concentrated, the light collection area on the generator is irradiated by sunlight and the temperature rises, and the solar energy is converted into heat energy by the principle of photothermal conversion, and the heat energy is driven by the heat engine (usually a steam turbine engine) to drive the generator, thereby generating electricity.
