Abstract
In this paper, we present a novel maximum power point tracking method for a photovoltaic system consisting of a photovoltaic panel with a power electronic converter; the whole is feeding a battery. This maximum power point depends on the temperature and irradiation conditions. A robust control using a PI regulator is used to track this maximum power point. Photovoltaic or in short term PV is one of the renewable energy resources that recently has become broader in nowadays technology. The demand or future work is looking for high efficiency, more reliable and economical price PV charge controller which is come in portable size has become very popular in PV system. In general, PV system consists of a PV array, charge controller, rechargeable battery and dc load.
