The ability to provide continuous power in any environment makes solar systems perfect for water pumping in remote areas. Solar pumping systems are flexible and modular and can be designed according to water demand or aquifer limitations. Some systems can work in hybrid configurations with other power supplies such as wind, generator or mains power.
The solar systems can be designed to pump up to more than 300.000 liters per day at lower heads to smaller water quantities at higher heads up to 300 meters.
The energy generated by the generator is used directly to pump the water, therefore batteries and charge controllers are not needed.
- unattend operation
- no fuel costs
- low maintenance
- easy installation
- long life (20 year)
- high capital costs
- water storage is required for cloudy periods
- repairs often require skilled technicians
Solar pumps are used principally for three applications:
- village water supply
- Livestock watering
