SOLAR WATER PUMPS
Solar water pumps
The moment you decide you need constant water supply in your area, home or farm or in any remote place, call us to deploy your Solar water services.
Solar water pumps are pumps that work with an electric motor whose power comes from photovoltaic cells located on solar panels that capture power from the sun’s light.
These pumps are often directly connected to a tank supplying a miniature water network or standpipes.
The pumps used are generally centrifugal force or suction-force pumps.
How does this work?
Centrifugal pump operating principle
The fluid is sucked in axially, due to the rotation effect of the impeller, into the pump body where it is radially accelerated in the vane before being forced out. The shaft is driven by an electric motor.
What is the “photovoltaic effect” ?
This is the direct transformation of light power into electric power thanks to photovoltaic cells. These are made from silicon with a purity and state (mono-crystalline, poly-crystalline, amorphous) that strongly influence the efficiency and cost of the cell. These cells are connected together and placed on solar panels.
There are different types of motors, DC or AC motors, and within each of these categories there are still more choices. Among DC motors, electromagnetic winding series motors are best suited to variable pumping capacity applications depending on sunlight. However, more and more often AC motors seem to be chosen for pumping using photovoltaic power (for these are low cost motors with enhanced efficiency thanks to the solar rectifiers used, which despite their extra cost, are worth it).
Ways of using a centrifugal pump supplied by a photovoltaic cell :
Sunlight is not a stable or easily predictable power source, hence there are two kinds of solutions for making up for this problem :
- A “Pump with battery” system where a part of the power is stored in a battery,
- A “Pump with the sun” system, the one most often found, where a tank serving as the reserve is combined with the pump for batteries are expensive and rarely last longer than two to three years.
Pump installation. Maintenance
This aspect requires calling in specialists and consequently their presence nearby. Maintenance is fairly simple and not very costly. It is necessary to ensure that there is a pump or water point management committee, or one needs to be created, so as to ensure proper use, follow up and safety for the installation, especially to limit the significant theft or damage hazards.
