In the article, the authors researched the process of increasing the energy efficiency of the solar air heating collector with heat accumulator. In order to increase the energy efficiency of the solar air heating collector with a heat accumulator, it was proposed to install flat reflectors parallel to its sides. Flat reflectors with a surface area of 1.8 m2 were installed on the sides of the solar air heating collector with a useful surface of 1.8 m2, and a pilot-industrial version of the device was created. According to the results of the conducted research, it was determined that the energy efficiency of flat reflectors depends on the solar declination angle. Research results show that, the maximum heat capacity of the flat reflector solar air heating collector with a heat accumulator was 1020 W. The maximum temperature of the heat carriers, air + 75°C and heat accumulator + 85°C.
