Design and Implementation of a Novel Photovoltaic Water Pumping System using Energy Storage Technology

The solar photovoltaic water pumping system has the advantage of pollution-free, fuel consumption less and etc., promotion the application of photovoltaic water pumping can alleviate the arid and remote areas without electric mountain agriculture and living water shortage problems, then improve the people's living standards. But the traditional photovoltaic water pumps have not the energy storage function, the only apply in outdoor light or strong sunshine intensity conditions, these factors limit the application range and increase the cost. A novel photovoltaic pumping systems with energy storage technology was proposed and study in this paper, the system uses scalable energy storage technology, greatly expanded the application range of the pump, the photovoltaic energy storage controller and photovoltaic pump speed controller were development and implementation. Finally, the validity and effectiveness of the proposed system are verified by the experimental results.
