Abstract: This paper proposes the development of a low-cost solar powered water pump (below US$50) for meeting the irrigation and household needs of the people of Koh Dambang, Cambodia. The geographical data, solar irradiance and water requirement data of Koh Dambang area was collected and analysed. The data helped in selecting a suitable pump and designing the solar panel accordingly. A 12 volts, 38 W DC powered centrifugal pump, powered by 12 volts, 50 W solar panel tilted at an angle of 15 degrees mounted on a flat surface was proposed for meeting the agricultural and household requirements of the people. The selected solar-powered water pumping system was priced at US$36 keeping in mind the cost consideration. The low cost solar-powered water pump appears to be a viable solution for the people of Koh Dambang owing to the ample sunlight which this region receives throughout the year.
