Abstract
The paper describes a study on the potential of solar energy in Mangystau oblast. This paper presents maps of solar radiation arrival kWh/m2/day by key months: January, April, July, October and for a year. A calculation of the solar energy potential, which can be received by the PV module for a year of opera-tion in Mangystau region, near the city of Aktau, was carried out. The results obtained give an idea of the solar radiation arrival on the vertical surface. The results of the study can be used for further, more in-depth calculations of the arrival of solar radiation, not only for Mangystau region, but also for other regions where there is a potential for solar energy generation. Test calculations showed good agreement with those presented in the literature.
