A New method to represent the I-V and P-V characteristics of different photovoltaic modules

In this study, a new method to calculate the one diode model parameters able to correctly represent the I-V and P-V curves of photovoltaic modules, is presented. The proposed method uses an iterative algorithm permits finding the appropriate value of the ideality factor and hence extracting the other parameters simply form datasheets information provided by manufacturers. The ability of the proposed model to calculate the current-voltage characteristics was examined by comparing the results with three other proposed methods in the literature for various photovoltaic technologies, such as polycrystalline, monocrystalline, Heterojunction photovoltaic modules.
