Solar Powered Water Pumps

December 2nd, 2008, Posted in Solar Powered Water Pumps

In many areas, grid electricity is unfeasable or simply not available. Pumping water from a well is costly if you need to use diesel or gasoline to run a generator or pump. In locations such as these, Solar Powered Water Pumps are a great option and can save money in the long run, since once set up they use no fuel. The renewable resource of sunlight powers the pump.

These pumps are Direct Current, rather than Alternating Current that is used for conventional water pumps. The reason for this is that DC motors are more efficient and can run directly off of solar panels or deep cycle batteries, without the need to run the DC current through an inverter. However, these pumps can be set up to run off of AC power as a backup, using a generator or the utility grid.

Typical solar powered water pumps have brushless motors and run water filled. This means that they are low maintenance, run cooler and aren’t prone to failure in the event of a seal leak into the motor.

They are quite commonly powered by an array of solar panels set up in series. These panels usually send electricity generated from sunlight to a  deep cell battery bank. When water is needed, the batteries supply the power. This way, water can be pumped even when the sun isn’t shining.

Different sizes of pumps are available, from one big enough to supply livestock herds to a pump for the cabin in the remote wilderness. They can pump water ftom depths of over 230 meters, depending on the manufacturer and model. Pumps are made that are big enough to supply a small village or resort.
