Solar Pumping

Utilizing solar power to pump water eliminates the need for grid power or continuously supplying fuel. Solar pumping systems are capable of filling hill top cisterns, supply water for irrigation and maintaining tank levels. AES has installed numerous systems to ensure households have sufficient water each day.

Why Solar Powered Pumping?

  • Facilitates sustainable remote pumping
  • Eliminates fuel delivery requirements
  • Reduces utility bill and operates when grid power is unavailable
  • Enables power independence in remote locations
  • Requires minimal maintenance
  • Provides reliable water delivery for irrigation
  • Increases property value
  • Reduces carbon footprint
  • Diversifies the energy supply

How It Works

Solar panels are responsible for providing the power to pump water from one location to another. Typically coupled to a DC pump, systems can operate with or without batteries. When the sun is shining, the pumps have sufficient power to deliver water. If batteries are added, the solar power charges the batteries for on demand pumping when needed.

Float switches are used to prevent overflowing or running the pump without water if pumping from a collection tank to a cistern or elevated tank to provide continuous water pressure.

Construction Considerations

  • Change in height between the supply and destination
  • Flow rates and distance required to meet demand
  • Pump sizing with respect to flow rate, distance and elevation change
  • Solar array size and location — Will the solar panels receive shadow free sunlight for a sufficient period of time each day
  • Level sensing requirements — Does wire need to be run to accommodate level switches
  • Are enclosures needed to house batteries and electrical switches
