Solar water pumps have been used since the early 1980's, and are used throughout the world for a number of different applications.
For people living in remote areas the cost of running power lines or diesel pumping of water may be too great. Solar water pumps are an excellent alternative.
Using pumps for farming, is the most common use of solar water pumps.
A solar powered water pump differs from a regular water pump only in that it uses the sun's energy to supply electricity for the pump. The solar panels absorbs the sun's energy and convert that to electrical energy for the pump to operate.
Because it is solar energy that is used, these pumps do work most effectively on sunny days. As the solar powered pump has no minimum speed a cloudy day simply means that the pump will still work but at a reduced rate.
There are many types and sizes of solar water pumps available. If the water source is a dug out, a floating pump will be used. If the water source is a well, submersible centrifugal pumps are needed.
Solar powered water pumps can be used to meet a variety of needs. The amount of water that can be delivered through these pumps depends on how far the water needs to be lifted, the distance travelled through a delivery pipe, the efficiency of the pump, and the amount of energy needed.
There is virtually no maintenance involved with solar water pumps. The pump itself being the only moving part. Generally, all that is required is an occasional inspection of the wiring and a look at the panels to check for bird droppings. Solar panels can be cleaned with a damp soapy cloth and water.
The installation of solar water pumping systems is a relatively easy process. The solar panels are generally mounted on a post and/or frame in a sunny location. The solar panel post/frame is designed to withstand winds of up to 140km/hr.
There are many benefits to using solar water pumps including ease of operation and running cost savings. By harnessing the energy from the sun and matching the correct pump for the desired application, you can save a significant amount of time and money.
The multitude of uses, easy installation, low maintenance and cost-savings are enough reason to persuade anyone to use solar water pumps.
