The PV panels cooling allows one to increase the photovoltaic conversion efficiency, as well as to obtain the waste heat product which can be for various purposes. This paper presents the radiator used for PV panels cooling. The cooling liquid is a water-glycol mixture, the PV panel electrical power output is 300 W. The radiator consists of various number of segments (U-tube), that are located at the PV panel width. The experimental data, collected at a stand installed at the laboratory of the Institute of Thermal Power Engineering at Cracow University of Technology allowed to determine the amount of electrical and thermal energy produced. For the studied time period, it was shown that the cooling system adopted on the PV panels with suntracking system, allows to produce up to 40% more thermal energy than the stationary PV panels with cooling.
