Utilization of MOSFET transistor as an electronic load to trace I-V and P-V curve of a solar panel

To understand the electrical behavior of a photovoltaic panel, it is necessary to know characteristic I pv = f(V ). The best way obtainthis I-V curve use variable resistor. This paper proposes new and simple technique based on MOSFET transistor as load, which whose gate voltage controlled by an RC filter from Arduino. A comparison under standard temperature illumination conditions between manufacturer’s datasheet with simulation MATLAB/Simulink one hand, other hand experimental data for evaluation this that has been performed.
