Ethiopia is among one of the most populated countries where agriculture is dominant sector inrnwhich the seasonal dependency prohibits the productivity of the sector. The availability of manyrnriver basin clearly depicts the irrigation potential the country has. The application of solar waterrnpumping technology for irrigation is an innovative and sustainable solution to address this issue.rnThe implementation of this technology can lead to several benefits which include the maximizationrnof productivity by halting the rainfall dependence and improves the living condition of farmers. rnThis research aims at designing and optimization of solar powered sprinkler irrigation systemrnconsidering the climatic data as it directly influences the irrigation water requirement. Severalrnmodels are adopted for the evaluation of techno-economic feasibility and environmental aspect. rnThe photovoltaic water pumping system with water storage tank that much the irrigation waterrndemand is proposed and several economic analyses has been conducted to establish the costrneffectiveness. Another investigated model is photovoltaic water pumping system with batteryrnstorage and conventional diesel fuel generator capable of delivering the same demand. The resultsrnshow that implementation of both photovoltaic systems is technically viable having performancernratio of 0.779 and capacity factor of 0.22 which is promising. The economic feasibility assessmentrnfound that net present cost of $24,224, $25,807 and $77,651 and cost of energy and $0.06/kWh,rn$0.07615 /kWh and $0.3077/kWh for PV system with tank storage, PV system with battery storagernand Diesel system respectively. The environmental perspective benefit has been also addressed byrnthe evaluation of the greenhouse gas emissions. Replacing diesel fuel by PV system that willrnprotect the environment from 17,500 kg/year of CO2, 132kg/year of CO, 4.82 kg/year of unburntrnHC, 42.9 kg/year of SO2, 150 kg/year NOx, 8.03kg/year of particulate matters. rnThis study shows that the application of the solar energy for irrigation is viable both technicallyrnand economically, and also leads to several environmental benefits including, carbon abatementrncost.
