Abstract

This paper explores the problem of overheating of solar modules as a result of exposure to sunlight. An increase in temperature above the standard leads to the degradation of solar modules and their premature decommissioning. Cooling the working surface is a key factor that must be considered in order to achieve higher efficiency in the operation of solar photovoltaic systems. Based on the considered methods of cooling and removing excess heat from the surfaces of the modules, an inexpensive and technologically advanced method for protecting solar modules from overheating using holographic films was proposed. The article presents the results of comparative laboratory tests of solar modules using such a holographic thermal protection. It is shown that when using a film, the SM performance does not change, and in some cases even gets better. The surface temperature of the module depends on the angle of its inclination to the horizon, which must be taken into account when choosing the location of installation of solar power plants. The experiments confirmed the assumption of effective protection of the modules from overheating using holographic thermal protection and showed its promise.
