Mathematical Modeling of different Photovoltaic Modules

Abstract

This paper presents a mathematical model for solar Photovoltaic (PV) cells and compares their performance to an existing model in renewable energy research center (RERC) at the University of Anbar-Iraq. The model is able to simulate both the I-V characteristics curves and the P-V characteristics curves and it is used to study different parameters variations that can affect on the PV array performance including operating temperature and solar irradiance level. The results of the PV characteristics curves are compared to the curves provided by Kyocera PV and Solara PV model datasheets. The results are extracted and simulated using the Matlab software. One-diode equivalent circuit is employed in order to investigate I-V and P-V characteristics of a typical 54 W and 100W solar modules. The simulation results will be used as a reference to compare the performance of both models under a dusty weather and also for comparing their performances by using the solar module simulator in our future work.
