| Summary: | The heat exchange of the photoelectric module with the environment and its changes in constant temperature were analyzed. Its temperature depends on the ambient temperature and the flux density of solar radiation, the heat balance equation is formed. The maximum concentration coefficient corresponding to the accepted limit temperature of 85 °C of the photocell was determined. It turned out that in the case of arbitrary installation of photoelectric modules, the maximum concentration coefficient does not exceed K = 3 at ambient temperature 25 °C, and K = 2,5 when installing the roof. An increase in the unit concentration coefficient in the summer leads to a constant temperature rise of the photocells to 18-22 °C, depending on the method of installation. A sandwich structural method of photoelectric module surface cooling was developed taking into account the increase in ambient temperature.
