Abstract

Renewable energy-powered water supply system is very essential and important to be adopted in Uganda as a means of pumping water because of their harmless, free gift of nature, user-friendly and durability. Solar water pumping system is the most economic and user-friendly pumping system that can effective and efficient used in pumping water. The battery-coupled solar water pump is the most suitable for pumping water because of its ability to supply water efficiently even when there is low power conversion efficiency. The battery-coupled solar water pump has the ability to work effectively during low irradiance because of the backup battery incorporated in the system to supply water to the reservoir when solar conversion energy is insufficient to supply the required amount of energy that can pump the water. The Battery-coupled solar water pump is highly recommended to be used in Uganda for supplying clean and safe water to their citizens as solar energy powered pump is durable, easy to maintain, user-friendly and harmless to the health.
