Feasibility of using alternative energy sources, current state and prospects of solar energy development is analyzed. Today, it is important to improve and develop new solar panels that would reduce their costs and increase efficiency. Efficiency of helioroof in the solar heating system with forced movement of coolant is analyzed. It is shown that heat can be used effectively with roofing building material. The results of research of incoming flow of solar radiation on the helioroof are described. The change of efficiency of helioroof at different speeds and different diameters of coolant tubes, change in the coolant temperature at the inlet and outlet of helioroof and coefficient of performance of the exposure time is investigated. Graphical and analytical dependence of efficiency of helioroof depending on the speed of the coolant circuit and the diameter of the tubes circulation is established.
