For any PV module, both current and voltage vary proportionally to the load and the solar radiation level as a nonlinear relation, which causes the continuous variation of the maximum power point (MPP). Since the maximum power for a certain load can be taken from the PV module at a distinct point for each radiation level, maximum power point tracking (MPPT) can be used to follow the optimum operating point. This paper presents design and build a simple MPPT based on perturb and observe technique for a small DC load driven by a PV module. The experimental results showed that using the proposed MPPT promotes a good matching between the PV module and its load. According to the good matching, the daily output energy can be increased by about 37-42% more than that of the direct coupling between the load and the PV module.
