Photovoltaic pumping system based on intel 80C196KC microcontroller

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. Thus, the enhancement of the photovoltaic pumping system efficiency depends on the optimization of the photovoltaic energy generation and the system consumption. This paper presents an optimally designed and realized photovoltaic pumping system which can be used for irrigation, under the variation of climate conditions, in the remote area, far away from national electric grid, of Batna region in Algeria. The photovoltaic pumping system is built at the laboratory level and the first tests of the control parts have showed very promising results.
