the article presents the ways of implementation of the strategy focused on the optimization of the process of heat transfer of solar installations, with the applied in their device combined heat exchange panel of aluminum profile elements tightly crimping copper tubes with coolant. Based on the comparative analysis of the two configurations of this device, the methods of heat transfer intensification from the absorbing surface to the working medium in flat-type solar collectors are proposed
