In this paper, we present a maximum power point tracker (MPPT) circuit and SFV simulation, to estimate the point operating of maximum power (MPP). Tracking and force the photovoltaic module (PVM) by a MPPT to reach this point and to stay there in a future time need to provide the maximum power available to the load. The load consists of a battery bank. This is obtained by controlling the duty cycle of a DC-DC converter through a sliding mode controller. The sliding mode controller is given the estimated maximum power point as a reference for it to track that point and force the PV system to operate in this point. This method has the advantage that it will guarantee the maximum output power possible by the array configuration while considering the dynamic parameters temperature and solar irradiance and delivering more power to charge the battery. The procedure of designing, simulating and results are presented in this paper.
