Comparative Energy Analysis of Photovoltaic Module

Abstract

This work introduces a comparative energy analysis of photovoltaic module using its different single diode equivalent electrical circuits (five-parameter model, four-parameter model, and ideal model). These equivalent circuits are used for different purposes according to the objective. The ideal model is still used in many applications particularly power system analysis and water pumping. Three commercially available (SUNTECH) photovoltaic modules (50W, 70W and 130 W) are used in this analysis at standard test conditions. Using those three PV modules; the relative errors of the maximum output power mismatch are highlighted in the three cases. Obtained results show that the five-parameter model gives the most accurate maximum power prediction in comparison to that of manufacturer’s data sheet, while the ideal model shows a remarkable relative error at the maximum output power which is up to 8.93013%. This evaluation allows users deciding on the selection of appropriate equivalent circuit to be used in a given application.
