This paper concerns the improvement of the maximal power point tracking using digital MPPT control of Photovoltaic (PV) systems. Works have focused on the feasibility of a PV system, an average power (200 W), in order to better adaptation of PV generators to the load (batteries), independently to sudden fluctuations of the weather conditions (illumination, the temperature) or of the load. The functioning of the MPPT control is based on an improved Hill climbing algorithm, taking into account the optimal electrical characteristics of the PV Panels. The experimental results of the designed PV system shows a net improvement in the MPPT search time and on the maximal power point precision by a factor of the order of 2.5, and the energy produced is increased by a factor of 5.5 %
