The paper presents the results of experimental studies of straight solar radiation in the Central Chernozem region of Russia. The intensity and flow of straight solar radiation falling onto a horizontal surface of a room were evaluated. Measurements were made of the flow of straight solar radiation on a horizontal surface through a translucent structure. Experimental data were obtained using a high-class measuring device in the period from July 1 to August 1. The measurement results showed an intense wave-like change in the solar radiation flux over 8 hours. The paper describes a method for estimating the intensity and flow of straight solar radiation falling onto a horizontal surface of a room. This method of evaluating daytime radiation allows one to determine the density of the total and straight radiation flux. Using this estimate to calculate solar installations used in the Central Chernozem region, their efficiency will increase by 10%.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
