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 ...
Choosing the Right Solar Collector. Active solar heating uses a collector to capture and absorb solar radiation. Here are the main types of solar collectors: Evacuated tube collectors: These collectors use copper tubes filled with liquid, such as water, contained in large vacuum-sealed containers. The evacuated tubes work more …
