The paper presents a universal Spice model that can be used for modelling the photovoltaic panels (PV) – namely the DC characteristics. The model was built on simplified schematic and fitting its parameters to the measured data. There were developed two types of the models – the simple model and the full model. The simple model is valid only for PVs with constant width of the PN junction strip (only the number and length are scalable). The full model allows user to set also the PN junction’s width. The simple model exhibits better accuracy, typically better than 5 %, while the full model’s accuracy is typically lower than 15 % (for illumination in the range from 20 lx to 2000 lx).
