Calculation of the intensity of solar radiation

This paper of this work is the solar radiation of methods for calculating the intensity of solar radiation by the analytical method and the method of coefficients. At the stage of developing a feasibility study for a solar heating system project, the choice of a method for calculating the influx of solar radiation intensity is important. As a result of the calculations, the graphs of the dependences of the total inflow of the specific heat flux per 1 m2 during the year were obtained, calculated using various methods. The calculations showed that the amount of incoming heat calculated by various methods differs significantly.
