Abstract: Due to rapid growth and declining cost of solar cells manufacturing as well as the progress of power electronics control techniques, photovoltaic energy is of increasing interest in pumping system applications particularly in the isolated area, such as in Batna region in Algeria. Obviously, Photo Voltaic Generators (PVG) are classified as non linear electrical sources since the output power is affected by the weather conditions such as insolation and temperature which changes randomly in time. Thus, the enhancement of the efficiency of the photovoltaic pumping system depends on the optimization of the electric energy generated by the photovoltaic generator. This study presents an optimally designed photovoltaic pumping system to work in the remote area of Batna region under the variation of climate conditions, it consists of: Maximum Power Point Tracking (MPPT), 3 phase Pulse Width Modulation inverter (PWM) Voltage Source Iverter (VSI) and induction motor actuating centrifugal pump. The system is governed by EV80C196MCS Microcontroller Evaluation Board. The photovoltaic pumping system is built at the laboratory level and the first tests have showed very promising results.
