Abstract :
This paper presents a discussion about a methodology to obtain the main parameters of solar panels and power converters in photovoltaic systems. This study is essential to obtain the maximum power transfer from the PV source to the mains grid or a load. It is also presented a formal mathematical model based on the experimental data acquisition of the key parameters of a photovoltaic cell which are: shunt and series resistances, photo generated current, the ideality factor and the diode reverse saturation current.
