Claim:
1. A method comprising: obtaining output power samples of power output from a plurality of photovoltaic (PV) cells, the output power samples comprising perturbed samples for which a perturbation is applied to an operating voltage or current of the plurality of PV cells and non-perturbed samples for which no perturbation is applied to the operating voltage or current; and generating a control output to change the operating voltage or current of the plurality of PV cells for a next perturbed sample by a next perturbation based on a difference between: (1) a change in output power between a non-perturbed sample and a perturbed sample preceding the non-perturbed sample, and (2) a change in output power between the non-perturbed sample and a perturbed sample following the non-perturbed sample,
