A solar water pump pumps water using the energy of the sun. It consists of an electrical pump system in which the electricity is provided by one or more PV panels types of solar panels . A typical solar powered pumping system is made up of solar panels that powers an electric motor, which in turn power a bore or surface pump.

Solar deep well water pump is specially designed to utilize DC electricity from solar panels. The pumps must work during low light conditions, when power is reduced, without stalling or overheating. Low volume pumps use positive displacement (volumetric) mechanisms which seal water in cavities and force it upward. Lift capacity is maintained even while pumping slowly. These mechanisms include diaphragm, vane and piston pumps. These differ from a conventional centrifugal pump that needs to spin fast to work efficiently. Centrifugal pumps are used where higher volumes are required.

A surface pump is one that is mounted at ground level. Surface pumps work well when they draw water through suction less than 10 or 20 feet. A solar powered submersible well pump is one that is lowered into the water. Most deep wells use submersible pumps.

Advantages of solar water pumps
The first advantage of dc solar submersible pump is that they are reliable in regional and remote areas. A perfect example of this is Africa, which is one of the poorest remote regions in the world with an abundance of water—but also the most dominant region when it comes to most days of sun in the year. On the flip side, Africa is thought to possess 9% of the world’s freshwater resources which translates to around 4,000 km3 of water per year. Deploying solar water pumps in Africa is, therefore, the perfect alternative to any other fuel-based sources—and an alternative which can stimulate life in every part of this continent.

The conclusion
If you are thinking or considering the applications of solar energy for agriculture, the benefits are numerous. With the ability to pump water for irrigation during dry and sunny weather in regions that need it most, panels like these can be easily installed and enable the pumps to work in wells of very low yields, offering a longer lifespan and plenty of energy in the long run.
