Concerning the issue of resource assessment for solar energy utilization systems in the climatic conditions of the Russian Federation

Abstract

The article deals with the distribution of the energy potential of solar radiation in the territory of the Russian Federation. The spatio-temporal regularities are revealed, which make it possible to assess the resource provision of engineering systems in a given renewable energy source. Graphical distributions of solar radiation for the northern latitudes of the Russian Federation, including the energy irradiance of vertical orientation surfaces by cardinal directions, are constructed. Equations are obtained for the possibilities of solar radiation depending on the considered month and latitude of the area. An amendment has been introduced that takes into account the decrease in the radiation intensity with average cloud cover for the regions. Revealed the territorial-temporal variability of the possibility of solar radiation, which makes it possible to assess the prospects of using or another system of utilization of radiation.
