Abstract

Photovoltaic (PV) module represents the fundamental power conversion unit of any PV system. The study determined the behavior of Renresola Virtus II module in terms of maximum power, voltage at maximum power, current at maximum power, open-circuit voltage, and short-circuit current. I-V and P-V curves were plotted. Single-diode equivalent circuit was considered including series and shunt resistances. The technical data used in the data sheet are rated under Standard Test Conditions namely: 1kW/m², 1.5 air mass, and 25°C operating temperature. The equations of load current, thermal voltage, shunt current diode current, saturation current, and light-generated current were converted into block diagrams using functional blocks in Simulink. In the estimation of resistances, one of the resistances was set to a fixed value while the other one was initially set to a reference value until the maximum power of the simulated model approaches the actual maximum power. The output parameters were compared to the data provided by the manufacturer in terms of percent difference. In determining the defects of natural parameters, 25 set-ups were simulated such that for every irradiance level, the operating temperature is varied. In all scenarios, both 1-V and P-V curves were plotted.
