DESIGN AND ANALYSIS OF SOLAR POWERED WATER PUMPING SYSTEM

Due to consider the fossil fuels, coal, and natural gasses, researchers doing much scientific research into it. As a result of the shortage of those above-mentioned factors, global warming may increase. To solve these problems, using natural renewable energy resources is one of the best sources of energy without increasing global warming. This research can be considered with the objective of supplying water to the agriculture purpose. Normally water pumping systems include a generator driven pump. These mechanisms have many problems such as: energy consumption, require high maintenance (fuel consumption) and diesel generator pump has environmental impacts. This study will address the above-mentioned problems by using a non-convectional based power system for water pump rather than using convectional based. Solarpowered water pumping system is one of the options, because it has less maintenance (no moving parts), easy to install, and, environmentally friendship via lifetimes and economically feasible after installation. MATLAB was used for modeling and simulation of Buck converter, Inverter, PV Cell, PV Array and HOMER software was used for PV water pumping economic cost analysis. The designed system is capable of providing 85m3per day daily water consumption of 92,400 litres per household at a total head of 76m. A comparison of the unit cost of water shows that PV water pumping is high at initial but drops to$0.16 per Kwh as installation completed than a diesel generator $0.22 per Kwh and $0.34 per Kwh of grid electricity. The outcome of the study will serve the community by supplying water and make the communities familiar with solar technologies.
