New Method to Compare Indoor and Outdoor Temperature Coefficients of Photovoltaic Modules

Abstract

In this study, a new method is presented to compare the indoor and outdoor temperature coefficients of photovoltaic module. Precise input of temperature coefficients introduced in the simulation is very essential to obtain accurate results about the actual performance of photovoltaic module/array. Thus, it is important to specify which type (indoor or outdoor) of the temperature coefficient is more accurate in simulating the actual performance. The short circuit current, the open circuit voltage, the output peak power and produced energy are considered as actual performance indexes. New method proposed in this study, simulates the actual performance for both indoor and outdoor temperature coefficients and compares with actual performance measured at field to decide which type of temperature coefficient is more accurate.
