Modern development of the industry is complicated without introduction of energy-saving technologies based on renewable natural energy sources. Solar and wind power plants, heat generators, solar collectors are wide spread in developed countries. One of it is device for transform solar into thermal energy. It is costly devices with low level of reliability and durability. Therefore actual tasks of this work are reduction cost of device for transform solar into thermal energy and increase it level of reliability and durability. These tasks are carried out by the way of substitution the main elements of device for transform solar into thermal energy by development polymeric compositional materials (PCM). As the polymer matrix is selected polycarbonate. This matrix is modified by silicon rubber and filled by graphite. The silicon rubber increase technological effectiveness by procedure of obtaining PCM. Graphite significantly increase tribotechnical properties of PCM in friction units with steel. Developed PCM can be recommended for application in main elements of device for transform solar into thermal energy, that lead to increasing of it level of reliability and durability.
