Abstract: This paper proposes highly economical, low price photovoltaic water pumping system incorporating a boost converter and a diode clamped multilevel inverter employing photovoltaic panel is initiated without batteries. This system is used in areas where electrical power is not accessible. Using photovoltaic energy is one of the solution to this problem. The converter boosts the voltage of the panel and inverter drives the Induction Motor by using Sinusoidal Pulse Width Modulation (SPWM) control. At the given irradiance level MPPT technique pushes the photovoltaic panel to obtain peak power. The performance of a solar water pumping system is discussed in this paper the system consists of a photovoltaic (PV) array, a permanent magnet (PM) DC motor and a helical rotor pump. The operation of the PV array is analysed using PSPICE. The efficiency of the system is improved with a maximum power point tracker (MPPT) and a sun-tracker. Simulation and field test results are presented.
