Solar Water Pumping
sample systems

Lorentz PS150 submersible centrifugal (shallow well, high volume)

• 1 24V 175 watt solar module

• 1 single module top-of-pole mount structure (2” ID SCH40 steel pipe required)

• 1 15’ array-to-controller wiring kit

• 1 Lorentz PS150 pump controller

• 1 Lorentz CSJ5-8 submersible centrifugal pump

• 1 Lorentz low water sensor

• 1 float switch

 Equipment total = $2,249

On average this system will produce ~2,100 gpd (gallons per day) when pushing against 50’ of head with 5 hours of full sun per day.

Lorentz PS1200 submersible helical rotor (deep well, low volume)
 

• 4 24V 180 watt solar modules

• 1 four module top-of-pole mount structure (4” ID SCH40 steel pipe required)

• 1 15’ array-to-controller wiring kit

• 1 Lorentz PV disconnect & junction box

• 1 Lorentz PS1800 pump controller

• 1 Lorentz PS 1800 HR-03H-2 pump

• 1 Lorentz low water sensor

• 1 float switch
  
  Equipment total = $5,469

On average this system will produce ~600 gpd when pushing against 760’ of head with 5 hours of full sun per day.

Note: the PS600 & PS1800 systems can be powered by a 120/240 VAC generator or utility power during cloudy periods by using the Lorentz AC power pack @ $745.

Here’s the chart that shows the cost versus performance of four more Lorentz pumping systems; let us know if any of them will meet your needs. All systems come with detailed wiring diagrams.

Head values listed include static and drawdown levels along with friction loss. Volume values shown assume a minimum of 5 full sun hours per day and are averages (i.e. your situation may vary somewhat). Prices shown do not include freight.

we can quote a system specific to your project needs.
