Abstract: This study deals with the study and the calculation of the coefficient of capture of solar radiation of a flat solar collector. The basic equations describing the energy balance of the flat solar collector. It is known that the surface of the transparent insulation the heat coming down: the flow of direct sunlight, the flow of the Sun’s rays reflected from the mirrors and the flow of the scattered (diffuse) radiation from the sky, from the surroundings which are absorbed by the individual layers of the heating surface. Compiled energy balance equation, a single layer of the heat element. Because compiled equation for steady state surface density of captured radiation is equal to the surface density of the heat flow withdrawn from the working medium of the receiver element (coolant) or the average temperature of the latter does not differ from the ambient temperature. In the above case, capture ratio is plant efficiency. The equation shows that the surface density of the heat flow, coolant withdrawn from the receiver can be calculated as the surface density of the trapped radiation minus the conditional heat loss and efficient heat consumption for heating system. Flow captured radiation is not dependent on the heat capacity of the system. Through analysis and optimization of the solar energy collector carried on a flat cavity with a modified receiver with regard to the content of incident solar radiation.
