In this paper a stand-alone Photovoltaic (PV)
systems is presented for water pumping. Solar PV water
pumping systems are used for irrigation and drinking water. PV
based pumping systems without battery can provide a costeffective
use of solar energy. For the purpose of improving
efficiency of the system perturb and observe (P&O) algorithm
based Maximum Power Point Tracker (MPPT) is connected to
this system. The aim of this paper is to show how to achieve an
effective photovoltaic pumping system without battery storage.
Results are presented based on different cases of irrigation
pumping application and availability of solar irradiance.
Simulation results using MATLAB/SIMULINK show that the
performance of the controllers both in transient as well as in
steady state is quite satisfactory.
