This article is devoted to the experimental study of the temperature regimes of the solar pond in the southern climatic conditions of Uzbekistan. The research was conducted in an experimental version of a solar pond that accumulates low-potential heat. According to research, when taking heat from a salt solar pond, without a coating on its upper surface and comparing the results of a glass-covered experiment is 10-15% higher than that of a glass-covered experiment, when the ambient temperature is 34 °C and solar radiation is 973 W/m2 it is scientifically based that the temperature of saline solar pond water with a concentration of 25-30% rises to a temperature of 53 °C in the lower part of the pond and that the energy storage efficiency of the lower convective zone of the solar pond increases in parallel with increasing solar radiation
