What are Solar Collectors? In concentrating solar-thermal power (CSP) plants, collectors reflect and concentrate sunlight and redirect it to a receiver, where it is converted to heat and then used to generate electricity. In tower (or central receiver) plants, mirrors, known as heliostats, track the sun on two axes, with each heliostat
