Abstract

Solar energy can be projected to be beneficial only when used to its full potential. The power obtained from the solar panel can be maximized by operating it under Maximum Power Point (MPP). Of various MPP tracker algorithms, Perturb and Observe (P&O) is the standard. Though easier in implementation, P&O drifts from MPP in fast changing atmospheric conditions. This paper proposes a P & O based MPPT algorithm which has improves the dynamic performance of P&O algorithm. The output power of the solar panel is used for tracking MPP thus reducing the complexity of the algorithm. This paper presents a battery charger system using buck converter. Here a microcontroller dsPIC30F4011 is used as MPPT controller to efficiently charge the lead acid battery from solar panel. The proposed charger system is economical and is appropriate for domestic applications. Analytical results shows significant increase in power harnessed from solar panel using the proposed algorithm.
