In locations where electricity is not available, other means are necessary to pump water for different applications. Using a diesel pump to deliver water causes economic and environmental problems. The higher price of diesel increases operation costs of diesel water pumping system thereby reducing the incomes. In addition, the use of a diesel pump emits a considerable amount of CO2 which cause global warming. A possible solution to these problems is using renewable energy source like solar power, which is environmentally friend and available for free. This paper presents the design and simulation of a photovoltaic water pumping system for irrigation of a potato farm located at a place named Gerenbo in south-west Ethiopia. The system was designed by considering the site’s topography and local meteorological data. The PV system designing was made in such a way that, capable of irrigating a hectare area potato farm with daily water requirement of 7m3 and total dynamic head of 21m. To run simulations, different tools have been used. Those include CROPWAT, MatLab, and HOMER. Furthermore, after seizing all components and sub-systems, the entire system (from solar radiation to water production) was simulated by using PVsyst. The economic and environmental aspects of PV water pumping systems have been studied. Based on the projected system lifetime production, the equivalent cost of water for PVWPs and DWPs is $0.1187/m3 and $0.3526/m3 respectively. Replacement of diesel-powered water pumping system results in an annual reduction of CO2 emissions by 1500kg.
