Solar energy has been considered as one of the reliable solutions for generating electricity necessary for human life. Easy access for all people without any cost, long useful life and usability, no need to build an electricity grid, transformer, etc. which is very costly, as well as ease of installation and easy and fast transportation, easy and fast installation and utilization in places close to consumers, usability in mobile systems and the need for suitable electricity sources for places far from the electricity grid make the use of this energy inevitable. To conduct this research, images from the year 2024 of the Landsat 8 satellite, OLI sensor and TIRS sensor, and the Sebal algorithm were used. ENVI software was used for geometric, atmospheric and radiometric corrections of satellite images as well as for performing calculations related to the Sebal model, and ArcGIS software was used to create a database, spatial analyses, cartographic operations and finally implement the model. The results show that the average maximum incoming shortwave radiation was 846 watts/m2 in August and the lowest was 313 watts/m2 in February. The difference in the amount of net radiation reaching the ground in the study area is due to the difference in the angle of the sun's rays and the number of sunny hours in different months of the year. It can be concluded that solar radiation from the radiation threshold to 1000 watts/m2 is received, it can be concluded that solar radiation in the villages of Chalus County has the necessary potential for implementing solar photovoltaic projects.
