An analysis of existing solar heating systems has been carried out. The dependence of the annual flow of solar radiation on the solar panel on the azimuthal angle γ and the angle of inclination of the surface, which can be used for studying surfaces with an arbitrary number of orientations, was obtained. The thermal balance for a given solar panel is presented for a certain period of time. Dependences for determining the amount of energy coming from the Sun on each of the surfaces of the solar panel and the amount of accumulated heat by the solar panel was obtained during the research. The losses of convection from the coating of the solar panel and radiation heat losses from the surface of the coating to the environment, as well as thermal losses due to thermal insulation from the back side and the side walls of the heliopanel, are analyzed. The dependence of the coolant temperature in the heliopanel depending on the annual solar radiation inflow and the total heat loss of the heliopanel has been obtained.
