Abstract

Maximum power point tracking (MPPT) techniques are used in photovoltaic system to maximize solar array output power under varying conditions. This paper presents simulation and experiment prototype results of a standalone PV system with multiple solar panels or cells and with different perturbation step sizes, including the realization of MPPT algorithm and power stage control. The controller tracks MPP of each individual panel/cell by sensing only the output currents in the PV system. The effect of the perturbation step size value on controller speed and accuracy is experimentally tested analyzed.
