Solar Water PumpingBasic Solar Water Pumping System
- Solar water pumping Solar pumping uses a free, easily accessible and renewable source of energy. Power bills are eliminated.
- With solar pumping maintenance costs are minimised. Solar modules are strong, robust and encapsulated into toughened glass in a sturdy, aluminium frame that will last even in harsh environmental conditions.
- Using solar allows opportunities for livestock, vegetables, trees and other crop production to be developed in areas where other forms of pumping are impractical.
- Solar water pumping systems are reliable. Solar systems won't fail on those hot, still days when the windmill stands motionless.
- Solar water pumps perform at their best and provide water throughout summer months when demand is greatest.
- Solar water pumping systems need little supervision requiring only periodical checking. Solar pumps automatically start soon after sunrise and continue to work unattended until sunset.
- Solar water pumping systems operate all year round, even on cloudy dull days with little or no direct sunlight.
- Solar modules have no moving parts and an expected working life of at least 20 years.
Types of solar pumping systems
Although solar water pumps
have been developed from some fairly sophisticated "hi-tech" components,
they are relatively simple, uncomplicated packages of equipment.
Solar water pumping systems
consist of three basic components:
- Power source (photovoltaic solar modules)
- Motor/pump (or motor/compressor) assembly
- Power controllers for matching the changing electrical output of the array to suit the motor/pump
