Abstract

Because of appropriate environmental condition and geographical position, solar energy is considered as one of the most efficient renewable energy types in Iran. This research intends to introduce a model by which it is possible to recognize the most optimum installation site for solar panels in urban environment. High potential of the highly elevated rooftops and direct exposure to sunlight and lack of their use in urban environments makes it necessary to utilize them optimally to produce energy from sunlight. In this research, properties of an appropriate site for installing solar panel in urban environment were primarily identified and then the required layers were determined. Layers required for accessing the appropriate sites were produced based on 1:2000 maps and were modeled spatially in ArcGIS using Boolean logic's AND and Product operators. These results were combined with land use and population factors by technique of Ordered Weighted Averaging‎ (OWA). The model was evaluated based on field observation and the Tao-Kendall coefficient was used to determine the homogeneity between the results of the model and those of field observation. The coefficient was calculated 0.771 that indicates a significant relation between the two parameters.
