System and method for power point tracking for photovoltaic cells

Abstract

A system includes a first photovoltaic sub-module connected with a second photovoltaic sub-module. A first differential power processing converter connects with the first photovoltaic submodule and the second photovoltaic sub-module, and a third photovoltaic sub-module connects with the second photovoltaic sub-module and the first differential power processing converter. A second differential power processing converter connects with the first differential power processing converter, the first photovoltaic sub-module, the second photovoltaic sub-module and the third photovoltaic sub-module, where the second differential power processing converter communicates with the first differential power processing converter to exchange an information about determined perturbation of the first differential power processing converter and the second differential power processing converter.
