Types of Solar Powered Water Pumps

Do you want to pump water for irrigating your farm or for your livestock? If that’s the case, then you have come to the right place. Solar water pumps are very efficient and cost-effective than using a grid-tied system to pump water.

In this post, we’re going to look at some of the different types of solar water pump systems and help you decide on which system is best for your needs.

Parts of the solar water pump system

A normal solar-powered water pump system is made up of a solar array, pump, controller, and a storage tank. The work of the pump is to move the water, the controller adjusts the pump speed, and the output power of the solar panel varies depending on several factors.

Before installing a solar-powered water pump system, you will need to know which solar water pump is ideal for your needs. Therefore, you will have to look at several specifics which will determine the type of system that you install in your home or farmland. These are:

  • The volume of water needed in a particular period of time for the application at hand. This may as well include extra water to be kept for seasons when solar power is not being generated or the PV panels have reduced output.

  • The amount of water available and it’s quality

  • The level of solar energy in the area

  • The total dynamic head for the pump

  • The system’s suggested layout and hydraulic basis

The four major types of solar-powered water pump

Submersible pumps

This type of solar powered water pump is usually utilized when the water supply is deeper than 20 feet from the surface. This pump has the ability to lift up to 650 feet and fit in a 4-inch or bigger well casing. Submersible solar water pumps are very convenient to use as they can function directly off solar panels, batteries, or in some situations, an AC power source.

When you use solar water pumps, water is normally pumped during the day when the sun is shining brightest and then stored in tank or cistern for use whenever required. It is important that a lot of water is pumped and stored for use during bad weather when no water is being pumped.

Surface pumps

These are suitable where the water supply is 20 feet or less from the surface. They are great for use with shallow wells, streams, ponds or storage tanks. Even though surface pumps generally can’t lift the water very high from a deep source, they can push the water to greater distances of around 200 feet or more.

DC pumps

Direct current solar pumps are more common in homes as they’re ideal for small applications such as landscaping and garden fountains. DC current pumps are usually low-priced when compared to other types of solar water pump systems. This is because they do not need inverters in order to produce AC power from the solar panels. Unlike other types of solar-powered water pumps, DC pumps are created to function with minimum electrical power, as a result, they have low flow rates.

AC Pumps

These are one of the most common types of water pumps on large farms. The AC solar powered water pump systems are usually driven by inverters producing AC power from solar panels. Unlike DC current solar water pumps, these are great for all kinds of applications from irrigation, to large-scale applications, and landscaping. They are popularly used in desert and for irrigation. Most AC solar water pump systems are available in power output ranges from 150W to 55kW.

Conclusion

Before rushing to buy any type of solar water pump, you need to identify your needs and consider your budget. There are different types of solar powered water pump systems and not every system will be good for your needs.
