An indirect conversion system that requires an intermediate step to transform solar energy into electric energy. Thermoelectric stations collect the heat proceeding from solar radiation and transmit it through a heat-carrying fluid that makes a thermodynamic cycle operate. This cycle consists of the production of steam through a heat exchanger. The steam then expands in a turbine, which is connected to an electric generator responsible for producing the electric energy.
There are three types of solar thermal power stations:
- Tower.
- Parabolic cylinder.
- Dish-Stirling system.
