 Iran has a large potential for solar energy production due to its geographic location and climate. A two-step framework was developed to identify the most suitable regions for solar energy production. First, a map of unsuitable regions was created using defined constraints. Then, criteria such as solar radiation, average annual temperatures, distance from power transmission lines, distance from major roads, distance from residential areas, elevation, slope, land use, average annual cloudy days, average annual humidity, and average annual dusty days were used to determine the suitability of different regions. Finally, the results were overlaid to create a priority list of regions with the highest potential for solar energy production.
