To evaluate the performance of photovoltaic systems, it is necessary to estimate detailed characteristics of solar radiation which varies with seasons, time, and weather conditions. The objective of this paper is to propose a method of evaluating the performance of photovoltaic systems, using probabilistic characteristics of solar radiation estimated at an arbitrary location by combining rough data observed meteorologically at the location with detailed data measured at another location. A case study on the electric power supply to a condominium is conducted. The validity and effectiveness of the method is clarified, by comparing the purchased and reversed electric power estimated by the proposed probabilistic method and calculated by the deterministic method with measured solar radiation. The performance of photovoltaic systems is also clarified in relation to the area and tilt angle of the photovoltaic array as well as the weather conditions of some locations.
