Maximum power point tracking techniques for solar water pumping systems

Abstract

In this paper, we present a comparative study of single sensor-based maximum power point tracking (MPPT) techniques for solar photovoltaic (PV) water pumping systems. A conventional hill climbing algorithm is employed to find and track the MPP, using the information obtained from either a voltage sensor or a tachometer or a manometer. The results of experiment are included and explained to validate the proposed techniques.
