...Many techniques have been presented to track the maximum power point (MPP) [2]–[8]; some have a very simple implementation but reduced efficiency, such as the constant voltage, fractional open-circuit voltage, and fractional short-circuit current methods, where the relationship between the open-circuit voltage/short-circuit current and the MPP voltage/current is assumed to be constant and independent of the environmental conditions [3]....

...The hillclimbing techniques, perturb and observe (P&O) and incremental conductance (InCon), are simple algorithms that can obtain high efficiency with a low computational cost and with no information about the particular PV to which they are connected with a sufficient degree of reliability [13], and for this reason, they have gained a predominant position among the MPPT algorithms....
