The design of the solar PV underground water pumping system in the Bilate basin, Ethiopia based on the data of solar radiation, average surface atmospheric temperature, wind speed and other weather condition. It is designed to satisfy the total power demand of the hydraulic pump using solar PV modules. The system components are solar PV module, charge controller, battery and inverter. The system is configuration made to supply 15 m3 water which is the maximum daily household water demand for the ten households from the 13 m deep underground water well. The hydraulic power of the pump calculated considering pipe friction and pump-set efficiency is 195.918 watts. Based this initial power demand, the number of PV modules, inverter and battery is determined. The number PV modules needed for this specific system is 6 modules, 6 inverters and 3 battery sets. The comparison analysis made by using HOMER energy software, the total cost PV system is $2,927, diesel fuel generator pumping system is $3,194 while wind power water pumping system is $5, 300 ignoring common pump set, water storage tank construction and pipes cost. Wind and solar PV systems are environmental pollution free while diesel generator water pumping system releases 241 kg/year CO2 and 0.483 kg/year SO2 to the living environment. In the case of total initial investment and total life time costs as well as the maintenance and operation costs and in case of pollution, solar PV underground water pumping system is more preferable.
