ABSTRACT: This paper presents the modeling of electrical I-V verification of photovoltaic modules using five-parameter models based on the minimum usage of input data, which are usually provided by manufacturer’s datasheet. However, we vary them with a step of 10-4, the ideality factor between 0.0 and 4 for each iteration in order to choose the value, which gives a minimal relative error of the maximum power point. Moreover, when is known, the other four parameters (i.e., Rs, I0, Iph and Rsh) are known. Finally, the effectiveness of this approach is then validated through comparison of the experimental results data under outdoor weather conditions.
