The article presents a method for determining the parameters of elements of a combined autonomous power supply system that uses wind and solar energy. A gasoline generator is used as a backup power source. Energy from the wind generator and solar panels is accumulated in the storage system, or distributed through the inverter to the consumer. During periods of calm, alternative energy sources are supplied from the gasoline generator. The following parameters of elements of the combined system of autonomous power supply are determined, namely, a wind generator, solar panels, a gasoline generator, a storage system, and an inverter. The analysis of wind energy potential and solar energy potential on the example of the surroundings of the city of Stavropol is presented. As an object of power supply, an individual subsidiary farm was selected. The optimal parameters of the wind generator, the area of the solar panels and the capacity of the storage system for the selected power supply object are determined. The wind turbine is made as a wind propeller type with the profile from the installation of WE-3000, solar panels adopted as panel brand BSP 32-100F. Graphs are presented of average power generation by the wind turbine, solar panels, and the gasoline generator. The average annual generation of electricity from wind energy, which was 44.7 %, from solar energy – 42.9 %, from a gasoline generator – 12.4 %, is presented. The total power generation by the combined autonomous power supply system is 1950.7 kWh, solar panels 836.6 kWh, wind generator 872.2, gasoline generator 241.9 kWh.
