Benefits of Solar Power Plants for Energy Supply to Consumers in Mountain Territories

In this paper, a new solution is given to an actual scientific problem of increasing the efficiency of power supply systems using renewable energy sources, aimed at optimizing power supply systems using solar power stations for consumers. The article calculates and selects the solar power supply for the autonomous power supply of the recreation center in the highlands. An analysis of the overall situation of solar energy in the world was presented. It is revealed that due to the length of the territory of Russia, the levels of solar radiation in different regions vary considerably. The useful specific solar energy of the Tsey gorge in the Alagir region of the Republic of North Ossetia-Alania has been determined. Various factors contributing to an efficiency increase of a solar power plant are considered. The use of a solar power station for electricity supply to consumers in mountainous areas can be considered economically justified, assuming that the payback period was 6.7 years, while the average payback period in the Russian Federation for stations of this type is 17 years.
