What are the characteristics of a photovoltaic (PV) module?

A photovoltaic (PV) module has non-linear I – V (current–voltage) characteristics and its P – V (power–voltage) characteristics shows that there exist only one point (Pmax) where the module deliver maximum power as shown in Fig. 1. This point also varies with the change in insolation and temperature as shown in Figs. 2 and 3.

Is accurate tracking of MPP voltage a goal for a MPPT algorithm?

How is PV array voltage adjusted around V MPP?

The PV array voltage is adjusted around V MPP regarding to the reference voltage V Ref that is the regulated array voltage. It is intended to match the V Ref to V MPP in the most proper adjustment. If this is not the case, then the algorithm tries to acquire the most adequate adjustment around the V MPP .
