Abstract: “Identification of solar potential of a region is important so as to reduce the return period of investment and to identify untapped regions like Himalayas, Tibet, Southern Andes etc. which were not considered to be good enough to tap the energy economically. This paper encompasses the use of fuzzy with weighted functions in identifying the same. The proposed method used various environmental constraints like solar irradiance, solar hour, latitude etc. for identifying the potential. For the sake of simplicity we have used only three of the above mentioned parameters but these parameters can be scaled up to any level, as desired by the experts, and also weights assigned to every parameter can be varied as per requirements and application area.”
