The world is increasingly paying attention to the use of so-called renewable energy sources – ground heat, wind energy, tides, biogas, solar radiation, and so on. Almost all of these energy sources are entirely due to direct influence from the Sun. Among these sources, one of the most promising is the direct conversion of solar radiation. The direct conversion of solar energy into heat or electricity is one of the main advantages of using solar energy as a future energy resource. The article presents the actual use of solar systems to provide hot water and electricity to educational and health establishments.
