ABSTRACT

A substantial growth of the installed photovoltaic (PV) systems capacity has occurred around the
world during the last decade, thus enhancing the availability of electric energy in an environmen-
tally friendly way. The maximum power point tracking (MPPT) technique enables to maximize the
energy production of PV sources, despite the stochastically varying solar irradiation and ambient
