Solar Water Pump: Things To Know And Tips For Use [2022]

Solar Water Pump

Solar water pumps don’t even need batteries as the solar panels directly power them. However, if you still use batteries, it will make a simple system more complicated. So, anywhere where the sun shines, you can use a solar water pump. Most people prefer to store water in a holding tank rather than storing electricity in batteries to power the solar pump during non-sunny days. 

With solar-powered water pumps, you’ll have access to water when you need it, but at a lower cost and with far lesser complexity. That’s why in remote areas, people mainly operate with solar water pumps as the cost of running a conventional AC-powered pump is expensive for those people. So, let’s find out how a solar water pump works and how you can use one.

How Does A Solar Water Pump Work?

How Does A Solar Water Pump Work

A solar water pump kit includes solar panel kits, a cable to link them to a solar charger, and the pump itself. It also requires tubing to pump the water and a water sensor to help manage the flow. 

A motor and a set of impellers are located inside the watertight housing. The motor drives the impellers, which push the water up through the attached tubing and to your preferred location, like water filters through holes in the pump.

Water is filtered via a debris-catching basket toward impellers, forcing the water out of the pump. It needs to be regenerated back into the pool if the solar pump is a pool pump rather than a submersible pump.

If the pump comes with more water sensors, they are installed at the water source’s origin. It is placed there to monitor the water levels and guarantee that neither the origin nor the water tank is overfilled.

But, how can solar panels supply energy to the water pump? Sun panels are waterproof frames that contain a large number of tiny solar cells. When you expose them to direct sunlight, these cells, which are made up of layers of specialized silicon, react chemically and physically. 

Now, solar power sends the electrons from one silicon layer to another through the forced displacement technique. It’s cyclical, and it happens every time a panel is exposed to sunshine. You can then store the electricity in a battery for later use, or you can feed it straight into the pump’s motor. It will keep the solar dc water pump running for as long as daylight permits.

Types Of Solar Water Pumps

A solar water pump can pump water from a well, recycle pools, remove flooded areas, etc. So, let’s look at the types of solar-powered water pumps;

Submersible Solar Pumps:

Submersible Solar Pumps

When the water source is deeper than 20 feet from the surface, submersible solar pumps lift the water up to 650 feet and fit it in a 4″ or bigger well casing. Solar panels, batteries, or, in rare situations, an AC power supply can all be used to power these kinds of solar water pumps. A submersible pump is a long-lasting metal or plastic item that is submerged in water. 

Surface Solar Pumps:

Surface Solar Pumps

During the day, while the sun is shining, water is pumped and stored in a cistern or tank for use whenever it is needed. To be prepared for periods of terrible weather when no water is pumped, it is recommended that several days’ worth of water be stockpiled. If you know how to install solar on rooftop, these solar-powered waters pumps are the best ones to use.

Linear Current Booster Solar Pumps:

Linear Current Booster Solar Pumps

These kinds of solar water pumps enable the motor to run longer during the day. This is because it translates additional voltage to the necessary current when the sunlight is low. It also allows the pump controller to increase its output to make the solar panel water pump more susceptible to damage while running dry.

Pros And Cons Of Solar Water Pumps

Pros And Cons Of Solar Water Pumps

Solar water pumps are entirely self-contained and require only that the solar panels are placed in a location where they will receive the most daily sunlight on a daily basis. However, there are some pros and cons of these solar-powered irrigation pumps, such as;

Pros:

  1. A solar water pump can do what it’s supposed to do without needing to be connected to the grid, no matter how close or remote you are.
  2. Pumping water, such as in swimming pools, is a daily task that can be pretty expensive. Renewable energy is free after installation and will help you save money on your energy bills.
  3. One of the most significant advantages of using solar products is that they emit no harmful carbon emissions, implying that they do not harm the environment when in use.
  4. These solar water pump for agriculture may achieve high maximum lifts and flow rates because solar energy is as powerful as grid-tied electricity.
  5. A solar water pump can be used in a variety of conditions. Furthermore, they are ideal in an emergency, such as during a hurricane, because they can function even if the power is off.

Cons:

  1. The use of solar technology necessitates the presence of sunshine. Without it, your solar panels will not generate enough electricity, and your pump may underperform, especially during the winter months in some places and during gloomy or low-light weather conditions.
  2. Once your array is installed, you’ll save a lot of money on energy bills, but there’s no disputing that the initial cost of these systems can be pretty significant.
  3. Many kits come with panels, but regrettably, many others do not. Unfortunately, that means you have to spend more money and time figuring out which panels you’ll need to match your pump.

FAQs:

1: Are Solar Water Pumps Any Good?

Ans: Solar power water pumps are suitable because they have a low operating cost and an even lower maintenance cost. They minimize the dependency on electricity as they function mainly in the sunlight. These pumps are eco-friendly, too, so they are an excellent addition to anyone’s home.

2: How High Can Solar Pump Lift Water?

Ans: Solar water pumps can lift water up to 200 feet, and they pump almost 500 to 1000 gallons of water per day. These solar garden pumps require servicing every 2-4 years. If you need a higher lift and need the pump to last more than 10 years, the Grundfos SQFlex solar pump is a good choice. 

3: What Is The Cost of a Solar Water Pump?

Ans: A primary solar water pump price that comes with solar panels is around $20,000. These kinds of water pump solar last from 2-5 years if they get proper maintenance. The baseline system will pump the water at a few gallons per minute flow rate from a few hundred feet deep.
