The article presents the results of a study of the regime of solar radiation in the southeastern part of Western Siberia. To characterize the regime of solar radiation, long-term observational data on actinometrical and meteorological stations were used. The dependence of the total annual global radiation on latitude received. The dependence of the sunshine duration on latitude it gives. The potential amount of total solar radiation per year under average conditions cloud cover and atmospheric transparency considered. Common regularities of solar radiation arriving to the slopes of varying steepness and exposure can be distinguished in mountainous areas. On the basis of the potential arriving of the total solar radiation in the southern part of Western Siberia we can distinguish three latitude zones.
