Understanding the Voltage – Current (I-V) Curve of a Solar Cell

For getting the maximal power out of the module, it thus is imperative to force the module to operate at the maximum power point. The simplest way of forcing the module to operate at the MPP, is either to force the voltage of the PV module to be that at the MPP (called Vmpp) or to regulate the current to be that of the MPP (called Impp).
