Abstract
Due to the fact that efficiency of PV panels decreases by approximately 0.5%/K, possibilities to stabilize the temperature on the panel's surface are considered in this paper. The aim of this investigation is to determine the transition temperature of PCM layer that allows avoiding rapid temperature fluctuations on the PV back surface. To meet the stated goal, dynamic simulations of thermal and electrical performance of PV/PCM panels were carried out using ESP-r software.Based on the obtained results, it can be concluded that additional PCM layer on the back side of PV panel can effectively increase the efficiency of electricity production with PCM transition temperature about 20°C.
