Hybrid power supply systems created on the basis of renewable alternative energy sources with different principles of generating electric energy are the most energy-efficient compared to systems built on the same type of energy sources. Combinations of different types of renewable sources in one installation make it possible to increase both the reliability of power supply to consumers and to increase the quantitative and qualitative indicators of the processes of generating electric energy. The most successful today are combined installations that combine wind generators and photovoltaic panels, the so-called wind-solar installations.
