Due to climate change and the need to reduce greenhouse gas emissions, the trend in the development of global energy is aimed at increasing the share of the introduction of environmentally friendly renewable energy sources. This contributes to ensuring sustainable heat and energy supply to the population and production in the zones of decentralized energy supply, which increases the energy security of the regions and the country as a whole. In addition, the introduction of renewable energy sources is seen as a key tool in adapting to climate change.
The report examines the climatic conditions of the territory of the Russian Federation in order to assess the prospects for the practical use of solar energy.
The basis of solar energy resources in a given point or region is the duration of the solar radiation and the amount of direct and total solar radiation entering the horizontal surface.
The research uses data from observations of the actinometric network of the Russian Federation. In areas where there are no observations of solar radiation, either indirect methods of calculation or access to open and accessible databases were used.
Based on the analysis of the complex of climatic characteristics selected for zoning, 10 radiation-homogeneous regions were identified on the territory of Russia, which were ranked according to the priority of the solar potential. The reliability of the boundaries of the selected regions was confirmed by comparing the spatial and temporal variability of the main radiation indicators. The selected regions can be divided into five groups: the most promising, promising, less promising, unpromising and unpromising.
The most promising regions are the regions south of 50N. The first region occupies the Primorsky Krai, the southern part of the Khabarovsk Region and the Amur Region, and the south-east of Transbaikalia. The second region is the southern part of the European territory of Russia.
The amount of total solar radiation entering the earth's surface for a year in these regions is 1330-1390 kWh/m2, which is the maximum for the territory of Russia. Both regions are characterized by a long duration of sunshine, especially for the first region (about 2400 hours per year). The high solar potential of these regions is indicated by the fact that in the period from April to September, the probability of a day favorable for the use of solar energy is 60%, in July it reaches 90%.
In less promising regions of Eastern Siberia, where there is a large influx of solar radiation in the winter and spring periods, it is advisable to use photovoltaic modules to generate electricity for autonomous consumers in areas of decentralized energy supply.
