Investigation of The Effect of Radiation on The Conversion Efficiency When Heating Solar Panels

The work studied changes in the efficiency of solar energy use in the hot climate of the Kyzylorda region. The purpose of the article is to analyze the effectiveness of solar panels for temperature changes and the intensity of exposure to solar radiation in the climatic conditions of the Kyzylorda region. It is known that the temperature of the solar panels under study and the level of light incident on them significantly affect the output power. The study was conducted in the laboratory «Energy saving based on renewable energy sources» at the Department of «Electric Power Engineering, Technosphere Safety and Ecology» of the Korkyt Ata Kyzylorda University. The data were obtained in the real mode of operation of solar panels with a capacity of 2.2 kW. The changes in the radiation efficiency during heating of solar panels were theoretically calculated and compared with the parameters obtained from the actual database. The heating of the panels was determined by a thermal imager. The weather temperature was obtained from a weather station located in the laboratory.
