Solar powered water pumps for irrigation
It has been a standard in home renewable energy systems since 1986. It is economical for domestic water supply, drip irrigation and water purification. Use solar-electric power to provide 250 to 10, 000ltrs per day from shallow water sources.
Solar powered booster pumps can push water as high as 140m (460ft). For 12 to 24V systems (1-2 solar modules or batteries in series) uses only one and the same motor and controller for solar direct or battery systems. Same flow at 12V or 24V ! The solar powered booster pump is not submersible, but can draw water from shallow wells, springs, cisterns, tanks, ponds, rivers and streams and push it through miles of pipeline. Applications can be drinking water supply, water purification and filtration, pressurising for home water systems, drip irrigation or water circulation in thermal solar collectors (max. +60 oC, +90 oC on request).
Slow pumping minimizes the size and cost of the solar array-battery system, wire and piping. The solar powered booster pump is more powerful, quieter and much more durable than plastic RV/Marine pumps. It is less expensive than submersible DC pumps.
Wearing parts typically last 5 to 10 years. Overall life expectancy is 15 to 20 years.
Suction Capacity is 5 vertical meter (20ft) at sea level. Subtract 1m for every 1000m altitude. Pump should be placed as low and as close as possible to the water source. Suction capacity my be further limited by intake pipe friction (or clogged filter) Intake piping should be 1? or larger.
Filtration Requirement: This kind of pump CANNOT tolerate dirt. Water MUST be filtered clear. If water is very dirty, improve the source or consider a different pump.
