How Many Solar Panels Does It Take to Power a Water Pump?

Before discussing the number of panels required to power a water pump, let’s clarify a few essential concepts that will help you understand what exactly it means to “power” a pump and how you can gauge the number of panels you need in different cases.

The power of a solar panel and a water pump is usually measured in Watts. A solar panel needs to deliver as much power as the water pump you’re going to use. Having a solar panel with power lesser than that required by the pump can result in many problems, including the subpar performance of the pump.

A single solar panel generally comes in 20-100 watts. The power of panels can vary, but we often come across 20-watt panels for operating solar pumps, which is why we will be using a 20W solar panel as an example here.

If you have a solar pump of 9W or 15W, a single solar panel should be enough to power the pump. However, when the wattage of the pump increases by more than 20W, you will need more than one solar panel.

For 21-40W, you can easily make do with two solar panels. Whereas for a 100W pump, you will require five 20W-panels. In this case, it is important to note that you can also use a single 100W solar panel, depending on how efficient it is. Both solar panel systems will provide you with the same amount of solar energy to power the pump. But you can compare your options to find which system would be better for you.

One way to choose the right system of panels is to check their cost against each other. If a system of five 20-watt panels is more expensive than a single 100-watt solar panel, you might want to invest in the 100-watt panel.

You should also check the kind of solar cells each system is made of. Solar panels are made of silicon cells that are either monocrystalline or polycrystalline. Monocrystalline cells often have higher efficiency and remarkable heat tolerance as compared to polycrystalline cells. However, polycrystalline cells are currently more popular in domestic use. There are amorphous cells, but they are not very efficient, so you should steer clear of them.

To simply answer the question, you can either get a couple of 20-50W panels together in a system to power a water pump, like many of the above-mentioned solar power water pump kits. Or you can invest in a single 100-200W solar panel.

Buyer’s Guide: What Should You Look for in Solar Powered Pump

A solar water pump is an ideal choice for those looking for an environmentally friendly option to irrigate their garden and small farms. In order to choose a powerful solar water pump, here are some of the features that will ensure that you get the best output from your unit.

Watch this video and learn about how to select and size a water pump for irrigation:

Rate of Water Flow

The rate of flow signifies the water lifting capacity of the pump. A solar pump with a rate of over 500 GPH (gallons per hour) is usually meant to water a garden or a small farm, whereas a solar water pump system with a low rate of flow is more effective for birdbaths and fish tanks. You need to analyze your solar water pump usage and then determine the rate of water flow you’ll need. A 100 gallons per hour or 1.6 gallons per minute rate would be adequate enough for pumping water in a pond or fish tank.

Longevity

Always go for solar pumps that promise long lifespan. You can either read the pump’s manual to determine its lifespan or check out customer reviews to see what other users say about its durability. . We highly recommend a solar water pump with at least 20,000 hours of a lifetime.

Solar Panel and Pump Power

It’s important to ensure that the solar power supplied by the panels exceeds the power required by the pump. Also, consider the panels’ efficiency when choosing panels for solar pump application. Since no panel offers 100% efficiency, you should always aim for panels whose output power is greater than the solar pump’s operational power.

Ease of Installation

Most solar water pump systems are made for domestic use, primarily as birdbaths or fountains. Therefore, their set-up and installation should be DIY-friendly, and you should be able to assemble and install them without any external help. Our list contains excellent options that offer easy installation.

Warranty

Warranty is another crucial factor to consider when choosing a solar water pump. A system with even a year’s warranty can save you a considerable amount of money in repairs and provide you peace of mind. Without a guarantee, you’ll likely have to invest in another machine in case anything happens to your unit.

FAQs

Is a solar water pump kit more useful than electric and diesel water pumps?

Yes, a solar water pump is more beneficial than conventional water pumps. It draws its energy from solar power, which is a renewable and inexhaustible source of energy compared to depleting resources like fuel and gas. This makes a solar water pump eco-friendly.

Another reason is the upkeep and maintenance of a solar water pump. Once you’ve installed a solar pump system, it’ll start working independently without any outside intervention. The unit does its job as long as the sun is shining. Some pumps come with a rechargeable battery that stores power to operates the unit when the sun isn’t around.

People are reluctant to invest in a solar water pump due to a high upfront cost. The amount of money you end up paying is usually twice the amount you’d pay for a fuel-powered pump. However, that’s the only money you will be spending on the pump, unlike a fuel pump which will require investment in fuel every few days or weeks.

What are the different kinds of solar water pumps?

There are mainly four different types of solar water pumps available in the market. These are:

Submersible pump

A submersible pump remains submerged in water, hence the name. These pumps are installed below the ground level, with the suction head at least 10m into the ground. The installation is done by digging a well in the water body, which increases the cost of installation and the effort.

Surface pump

As the name indicates, a surface pump can stay on the water surface. It’s used to pump water from surface sources like ponds, water features, springs, shallow wells, or sources where the water table is less than 10m. It doesn’t require excessive effort and has a lower cost of installation.

AC pump

These pumps require AC (alternate current) to operate, which means that an inverter must convert the DC produced by the panels to AC.

DC pump

This is a simple solar water pump that does not require any batteries or inverters. It takes the DC (direct current) from the solar panels to irrigate farms and gardens.

Can I change the location of my solar water pump?

Depending on the type of the pump, you can definitely change its location. If it’s a surface pump, you can move and reinstall it elsewhere without needing any extra equipment. A submersible pump, however, can’t be relocated as it’s submerged in water.

Can the solar panels be damaged due to rain/snowfall?

Modern solar panels are weather-resistant and can protect themselves against any rain or snowfall. So your panels won’t be damaged unless they are struck by lightning. Heavy rains and storms can also damage the panel’s base and result in glitches.

Do solar water pumps require any maintenance?

Solar pumps require minimal maintenance. This includes cleaning the panels to avoid clogging and ensure maximum exposure to sunlight for better efficiency.

Final Thoughts

When installing your solar-powered pump, make sure you place the solar panel in direct sunlight with no shade or cover. Also, make sure to place it away from children and/or pets. Regularly clean the panels for better maintenance and improved efficiency.

All the products on our list are highly reliable, durable, and long-lasting. However, it might be a little tricky trying to find the right unit for your needs.
