Meteorological factors affecting the operational efficiency of the solar hot water supply systems have been considered. The solar radiation incident on the receiver of the solar collector, determined on the basis of observations at the actinometric stations and the calculations of the solar radiation using the data on total and low cloudiness, as well as such characteristics as the outside air temperature, wind velocity, frequency of dust storms and fogs using the data obtained from 32 meteorological stations in the key districts of Uzbekistan were used as the basis for the division into districts.
