    • SP14-13 : Typical lift height: 55m à 75m
    • SP17-6 : Typical lift height: 40m à 55m
    • SP30-4 : Typical lift height: 30m à 40m 
  • 16 x polycrystalline photovoltaic panels 265Wc
  • 1 x 10 meter solar cable
  • 1 x power and safety box WU-4T


The pump is powered by solar panels (via the power / processing package ): it starts to work the morning the first rays to stop the evening with the sunset . The fresh water is stored in a tank, a pool or a water tower.



A stop sensor (optional) allows to stop pumping water when the tank is filled .
Depending on the depth of immersion of the pump , the length of the submerged electric cable must be determined.
The choice of the submersible pump depends on several parameters : location, lift height , everyday, losses, ...

Grundfos Pumps


Grundfos pumps are borehole pumps with very high output flow medium and small diameter . They are designed to draw water drilling , underground rivers , as well as tanks or rainwater collectors for home use , garden, agriculture ( automatic watering, irrigation ), but also industrial pumps ... stainless steel is a very good corrosion resistance . They allow corrosive water pumping and have good resistance to sand and abrasives, protection against engine breakdown and easy maintenance . It must be installed so that the suction strainer is completely submerged . It can be installed both vertically and horizontally with cooling jacket. Choosing a pump model depends on : the total head (including pressure losses ) , the required daily volume and location

Material: stainless steel AISI 304

Max. pumped liquid : 40 ° C

Basic Cable : 1.7m

Diameter : 4 inches

Power and safety box


The box is completely pre-wired and delivered " plug and play" . It equipped with MC4 connectors allowing easy connection of photovoltaic panels. The box contientégalement a switch to turn the power supplied by the solar panels.

An inverter converts the DC electricity produced by the solar panels into alternating current. A circuit breaker protects the motor power supply from overcharge and overcurrent.
