A study of effect to the water pumping system powered by pv solar by removing the battery storage / Ahmad Izzat Mod Arifin ... [et al.]

The deficit in electricity and high diesel costs affects the pumping requirements of community water supplies and irrigation therefore using solar energy for water pumping is a promising alternative to conventional electricity and diesel based pumping systems. Water pumping system has a long history, so many methods have been developed to pump water. Manual pumping is the common method for many years, but it is impractical for many applications, such as unmanned or remote wells. Many pumping systems require an independent power source like an engine or electric power. Engines can provide the higher amount of the water, but they are requiring the fuel and regular maintenance. In order to minimize the cost, the alternative source is being used such as solar energy. This paper presents the performance review of water pumping system powered by photovoltaics (PV) solar. The purpose of this article is to review the performance of the water pumping system based on the model and experiment that were conducted. This paper also disscuss about the optimum sizing of PV module, batteries, flowrate of water, and also the characteristic of charging and discharging pattern. The method of sizing were adapted from SANDIA National. The system based on the off-grid system configuration which contains PV module, charge controller, batteries, and load. Based on this research, the method of sizing from SANDIA National can be used to set up for off-grid water pumping system and it able to support the system for 2 days autonomy
