Solar Pumps

The solar water pump is a small device Immersed in the water and powered by solar.

The main components of the Solar Pump 

The solar pump consists generally of three main components:



  • PV Modules ( one or two panels )
  • Pump
  •  The controller  



There are also secondary components like the filter, the inverter(for a combined system ), batteries.

The system is easy to install and you have the choice to use a battery if you want the system to work during the night and if you don’t, no need for batteries.


Also if you have an isolated farm and you can’t control it, there is a small device it called the floater, its role is to shut down the pump if there is no water in the well or in the tank. In this case, the system will only work when there will be no danger.

The panel converts the rays into electrical energy with the help of Si wafers fixed within the PV panels. Then the solar energy supplies to the electrical motor to operate the pumping system using cables. By the revolution of the shaft which is fixed to the pump, then the pump begins to pick up the soil water and supplies to the fields.

 Types of Solar Pumps

There are two types of solar water Pumps:

1-Submersible pumps System

It can lift up to 198 meters and fit in a 4″ or larger well casing and are used when the water supply is deeper than 20 feet from the surface.
 Submersible solar pumps can operate directly off solar panels, batteries, or in some cases, an AC power source. Water is usually pumped during the day when the sun is shining and stored in a cistern or tank for use whenever needed. It is recommended that several days’ worth of water is stored to be prepared for stretches of bad weather when no water is pumped.


2-The total Surface needed  System 

These pumps are used in ponds, shallow wells, storage tanks otherwise streams. If the deepness of the water supply in the well is 20 feet or less than 20 feet from the surface. Generally, these pumps can’t pick up the water very high from the deep well, they can push the water 200 feet or above distance. These pumps are apt for pumping as well as lifting water from the highest deepness of 20-meters.


Advantages

  • Designed for use in remote and harsh conditions
  • Fast and simple installation
  • Large range of pumps to closely match each application and optimize efficiency
