Types of solar collectors

Solar thermal collectors are devices capable of capturing solar radiation and transmit it to a fluid, for later use.

The solar collectors are divided into two groups:

Solar Collectors without concentration: And they do not exceed 70 ° C, so they are used in the applications of solar energy of low temperature heat. An application example would be the production of hot water.

Concentrating Solar Collectors: Which, using the methods of concentrating optics, are able to raise the temperature of fluid above 70 ° C. These are applied in solar thermal medium and high temperature. We can find examples of these in the thermal solar plant in Almeria (Spain), Grenoble (France) and in California.
