What is a Solar Water Pump?

A solar water pump is a device used to transfer water from one point to another. It is powered by converting solar energy from the sun into direct current which then powers the water pump. A typical solar water pump consists of two major sections – the solar panel which converts the suns energy into direct current and the DC Water pump which operates with 12 or 24 volts direct current.

How a Solar Water Pump Works

Solar water pumps brought much attention to themselves with the recent changes in prices of oil that hit everyone. A similar thing occurred in the late 70s but people failed to learn the lesson. The moment oil prices came down, so did the idea to use more endurable energy options. A solar power pump is a pump operating on electricity by solar panels or the thermal energy provided by collected sunlight instead of conventional electricity. The running of solar water pumps is more affordable mainly because of the lower operating and maintenance charges and has little environmental effect than pumps run by a built in combustion engine. Solar power pumps are useful where electricity is unavailable and substitute sources (particularly wind) do not give enough energy.

Solar water pumps can offer a good alternative to conventional grid tied water pumps. For remote areas where water is needed, a solar water pump can be the perfect solution. For home owners with a water feature in their yard, solar powered fountains and pumps can be a more efficient approach. Solar water pumps change solar power from the sunshine into electrical power to run water distributing pumps. Cells on solar panel systems are covered in a semi-conductor material that transforms the sun’s energy into direct-current power. DC currents travel through electrical wires to power the pump which moves water. Some solar power water pumps have a battery charged with solar power through the day so the pump can be run overnight. Solar panels normally work best when positioned somewhere sunny and facing south.

Types of Solar Pumps

There are 2 main types of solar power pumps. Surface pumps are placed above ground surface and move water via pipes. These are useful for moving large volumes of water at a gradual speed. Surface pumps are generally found on farmlands or large irrigation where water has to be transferred from a lake or other body to landscaping or fields.

You can also get submersible solar power water pumps. These devices are installed under-ground, but the panels are connected above ground surface. Submersible water pumps are used to transfer water from inside wells to the surface area.

Uses of Solar Water Pumps

Solar water pumps may be used to run fountains, swimming pools and perform farming projects. Solar water pumps are useful in places where water sources are far, fuel costs are high or power is lacking. Livestock watering is one of common use of solar water pumps. Solar pumps are used year-round in temperate areas. Water pumps with solar energy are likely to move smaller quantities of water over a long period of time compared to traditional AC powered pumps.

Solar power water pumps use solar energy as a good option to bring water to rural areas, cabins or campgrounds. Most people have used solar drip irrigation and pumping for homes and gardens. This innovation has been around for many years, is cost-efficient, and there are many government plans and utility rewards to use it. Solar power water pumps are very cheap to power and cheap to build; and after the first cost, there is nobody else to pay.
