Optimization of the components of a solar powered pumping systemfor rural communities

Abstract

The elements and variables composing a pumping system run with solar energy were analyzed, based on the technical characteristics and specifications of the different components and their interaction, associating this information to cost, robustness and availability, in order to determine and be able to propose the best options for water pumping from a cost/efficiency point of view. The optimal solution is the conversion of DC voltage to 110 V AC. Panels should generate the energy needed to run the pump, while the battery bank should be the minimum to ensure the amperage needed to start the pump. Peripheral pumps have the lowest energy consumption per pumped liter of water, as long as the total pumping head is below 20 meters. A pumping system run with solar panels was designed and tested, which can pump between 6 and 10 m3 per day, with an investment of USD 2330.
