The article considers the effect of temperature on the efficiency of photovoltaic modules and analyzes the methods of their cooling. It is shown that increasing the operating temperature of solar panels leads to a decrease in voltage, output power and accelerated degradation of photovoltaic elements, and that various approaches are used to reduce the operating temperature and increase efficiency. An overview of various cooling methods for increasing the productivity of photovoltaic panels is presented - passive, active and combined systems for cooling photovoltaic systems using air, water, phase transition materials and nanofluids as working agents and other methods. Depending on the intended use, it is advisable to use the appropriate method to increase the efficiency of photovoltaic modules and/or to produce additional thermal energy. As a result, it was found that there is no universal method for cooling photovoltaic modules, and the choice of the optimal cooling system should be carried out taking into account climatic, structural, economic and operational factors.
