Performance analysis of MPPT charge controller with single and series/parallel connected PV panels

Abstract

Maximum Power Point Tracking (MPPT) charge controller is used as an intermediate device in solar system between photovoltaic (PV) panels and batteries. Multiple panels are usually used to meet higher energy demands in large solar PV systems by connecting them in series/parallel configurations. This piece of work is based on performance analysis of MPPT charge controller with series and parallel connections of solar PV panels. The effect of each configuration is analyzed using software and hardware setup. Reason for varying output behavior of MPPT with different connecting schemes of PV panels is discussed. The combined results of electrical tacker (MPPT) and mechanical sun tracker are also presented in this paper for both of above said configurations.
