Output power samples from one or more photovoltaic (PV) cells are obtained. The output power samples include perturbed samples for which a perturbation is applied to an operating voltage or current of the PV cell(s) and non-perturbed samples for which no perturbation is applied to the operating voltage or current. A control output, to change the operating voltage or current of the PV cell(s) for a next perturbed sample by a next perturbation, is generated. The next perturbation could be based on an estimated change in output power due to a previous perturbation. The next perturbation could also or instead be in a direction based on a change in output power samples, and of a magnitude based on the direction and a direction of perturbations applied for one or more perturbed samples preceding the next perturbed sample."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photovoltaic system maximum power point tracking","description":"Photovoltaic system maximum power point tracking methods and apparatus are disclosed.
