PHOTOTHERMAL

In these plants solar radiation is reflected in mirrors (heliostats) and is directed to a boiler located at a certain hieht to heat the fluid in it. This fluid transfers the heat in an exchanger in order to generate steam. The steam produced here is used to drive a turbine and thus the shaft of the turbine produces electricity in a generator.

They are non-polluting plants and they used free fuels. In contrast, this is a random and discontinuous energy due to the sunlight hours, this type of power plants are expensive and their performance is low in comparison to other conventional power plants.
