Sustainable domestic water pumping using solar photovoltaic

Context

Pumping of water for domestic and productive uses has been difficult to maintain in Tanzania. This challenge is highly attributed by the higher costs of pumping water using conventional means such as diesel generators and electricity.

Solar  Photovoltaic  (PV)  technologies have enabled rural communities of Tanzania to apply this technology for lighting, water pumping, charging of cell phones, etc. Community  water  projects  using  solar  pumps  have  benefitted from reduced running costs as compared to diesel or electric water pumps.
