Thermal solar systems can also be used to generate electricity. For this purpose, relatively high temperatures need to be achieved, which is achieved by collecting solar radiation in a small area or part of the collecting surface. The radiation is concentrated using special mirrors. In recent years, solar-powered systems with the technologies available in parabolic mirrors, solar power towers and solar discs have been able to make substantial contributions to the production of electricity from the sun. In all three of the above technologies, solar energy is concentrated at a specific point through a heating medium (water, oil, etc.), which is heated by a steam generator, which is then used for power generation by steam generators. These technologies are now mature and for the most part they are suitable for exploiting the very high solar potential of the Mediterranean countries.
