A high-capacity solar panel is not all that defines the best solar water pumps. Factors like flow rate, head lift, pump efficiency, and power source flexibility add to the total quality a solar-powered water pump for irrigation will offer. Then the ease of maintenance and resistance to corrosion will determine how long you get to use your solar pump.
Our Top Choices
- ECO-WORTHY Solar Water Pump Kit System – Overall Best Solar Water Pump for Irrigation
- Amarine Made DC 12V Farm & Ranch Solar Water Pump – Highest Flow Rate
- BACOENG DC Farm & Ranch Solar Water Pump – High Flow Rate
- BACOENG DC 12V Solar Water Pump – High Flow Rate and High Durability
- ECO-WORTHY 12V DC Submersible Deep Well Pump – High Maximum Lift and Power Source Flexibility
Obviously, a solar water pump will run on energy from a solar panel. And the higher the capacity of the panel, the more power the pump has to function. So, getting a solar water pump with a high-capacity solar panel is a no-brainer.
The flow rate of solar pumps is perhaps the primary marker of their quality. A solar-powered water pump for irrigation with a low flow rate will frustrate you because it will produce water slowly and with less force. But one with a high flow rate will pump high volumes of water per unit time, which is desirable.
You could say the efficiency of your solar water pump is a definition of how much power it needs to pump water. Generally, a high-efficiency pump will produce large volumes of water while consuming relatively less power than a low-efficiency pump.
The maximum head lift of a pump defines the total height between the water source and the destination of the water. The higher the maximum head lift of your solar pump, the farther the water it pumps can travel from the water source.
The sun will not always shine. So, if your solar pump relies only on solar energy to function, the absence of the sun means no operation. To avoid this, you should opt for a water pump that offers the flexibility to use other power sources besides solar panels.
Then, of course, a water pump will be exposed to water, sun, a host of various elements. But if it offers no resistance to corrosion and cannot be maintained easily, it may go bad sooner than you expect.
Our List of Best Solar-Powered Water Pump for Irrigation
ECO-WORTHY Solar Water Pump Kit System
The ECO-WORTHY Solar Water Pump Kit System is worthy of the top spot on our list because it is well-rounded. It has a remarkable maximum lift, the flow rate is decent, the solar panel is efficient & powerful, and the pump is fairly efficient. Beyond those features, the ECO-WORTHY Water Pump Kit System offers significant resistance against corrosion.
The ECO-WORTHY Solar Water Pump Kit System is made with various anti-corrosion materials. For one, the stainless steel strainer and the copper core power cable will leave no room for corrosion. So, you can have the pump around for very long. Beyond that, the stainless steel strainer prevents clogging and adds some aesthetic appeal to the appearance of your pump.
The ECO-WORTHY Solar Water pump comes with a controller that operates in 4 modes. Each one of these modes prevents the pump from overworking, and therefore, prolongs its lifespan. So, coupled with the corrosion-resistant parts, the controller contributes to the durability of your pump.
The controller is pretty flexible; it is compatible with 12 volts and 24 volts battery to handle 360 watts or 720 watts.
The ECO-WORTHY Solar Water Pump Kit System has a maximum lift of 230 feet – the highest of any product on this list. Only the ECO-WORTHY 12V DC Submersible Deep Well Pump matches this value.
Of course, with a lift of 230 feet, the ECO-WORTHY Solar Water Pump Kit System makes it possible to pump water from lower depths to higher surfaces. This means you get some flexibility in setting up your solar-powered water pump system – you can have a very high discharge point, which is good if you are getting a storage tank for irrigation. Plus, since the maximum submersion is 100 feet, you can have a very deep water source.
The flow rate of the ECO-WORTHY Solar Water Pump Kit System is capped at 1.6 gallons per minute (6 liters per minute). This falls short of the flow rate of the Amarine Made DC 12V Farm & Ranch Solar Water Pump, the BACOENG 12V DC Farm & Ranch Solar Water Pump, and the other two products. Yet, it should be enough to offer you decent irrigation.
The ECO-WORTHY Pump Kit System comes with 2 solar panels made up of monocrystalline cells. So, the efficiency is not in doubt. Each solar panel has a power rating of 100 watts, making a total of 200 watts. Since the pump consumes a maximum of 96 watts, the solar panels definitely offer enough power to run it. Then compared to its rate of water flow and maximum lift, the estimated maximum power consumption of this pump shows that it is fairly efficient.
In the absence of direct sunlight, you will be unable to use this pump, except you get a battery. Thankfully, you can use a battery with it. Unfortunately, however, the product does not come with a battery in the package. So you have to get one yourself.
- It has the highest maximum lift on the list – only matched by the other ECO-WORTHY pump.
- The rate of water flow is decent but not the highest on the list.
- The solar panel has a high capacity. In fact, it is the only product on the list that comes with a solar panel.
- It offers power source flexibility since it can run on solar energy and the DC output of a battery.
- The rate of water flow can be higher.
- While it can work with a battery as the power source, it does not come with a battery.
Amarine Made DC 12V Farm Solar Water Pump
The Amarine Made DC 12V Farm Solar Water Pump boasts the highest flow rate of any product on this list. But more than that, it boasts an efficient pump, a corrosion-resistant body, and a decent maximum lift.
The Amarine water pump produces a maximum water flow of 26.4 gallons per minute (100 liters per minute). No other product on the list matches this, and this is pretty huge. In other words, when this submersible pump is working at full capacity, it can fill a 100-liter tank in just one minute.
Beyond this product’s impressive maximum water flow capacity, most of the body is crafted with stainless steel. So, you can expect significant corrosion resistance. Then there is the strainer, also made of stainless steel, which prevents clogging. The anti-corrosion body and the anti-clogging strainer together enhance the longevity of the product.
Furthermore, there is a waterproof seal. This seal keeps water out of the electric compartments. This way, it prevents electric shocks, and there is minimal risk of the pump getting damaged by water.
The Amarine Made DC 12V Farm Solar Water Pump has a maximum lift of 26 feet. While this falls way below the maximum lift of the ECO-WORTHY Solar Water Pump Kit System and the ECO-WORTHY 12V DC Submersible Deep Well Pump, it still goes a long way. It is no wonder it finds applications in small farm irrigation, pool drainages, fountains, ponds, and troughs.
The Amarine Made DC 12V Farm Solar Water Pump has a power rating of 125 watts. And seeing how much water it pumps out per minute with such power consumption, the efficiency of this product is undeniable – no other product on the list comes close.
Unlike the ECO-WORTHY Pump, the Amarine Made DC 12V Farm Solar Water Pump does not come with a solar panel. So, you have to get one separately. A solar panel rated 100 watts, and 12 volts would do. But you should get about 2-3 100-watt panels for better performance. Also, the Amarine Made DC 12V Pump does not come with a controller, unlike the ECO-WORTHY Solar Water Pump. So, when getting a solar panel, you should get a controller too.
Besides running on solar energy, the Amarine Made DC 12V Farm Water Pump can be powered with batteries. However, the product does not come with batteries, so you have to get one separately. A 12v battery would do, but one with a low current rating may not power the pump for too long.
Once you get solar panels and a suitable battery for this solar-powered water pump for irrigation, you should be able to use it under any condition, even at night.
All in all, the product is lightweight, powerful, efficient, easy to set up, easy to use, and has low maintenance requirements.
- The pump is pretty efficient, and no other pump on the list comes close.
- The flow rate is very impressive – the highest on the list.
- The product is considerably corrosion-resistant.
- The power source of choice is flexible.
- It does not come with a solar panel, controller, or batteries – just the pump.
- The maximum lift could be higher.
BACOENG DC Farm Solar Water Pump
With the BACOENG DC Farm Solar Pump, you are getting a high rate of water flow. But beyond that, you can count on the durability and pump efficiency of this product.
With the BACOENG DC Farm Solar Pump, you get two voltage options: 12 volts and 24 volts. The difference between both? Their flow rate. While the 12-volt BACOENG DC Farm Pump has a maximum rate of water flow capped at 20 gallons per minute (over 75 liters per minute), the 24-volt variant has a flow rate of 24 gallons per minute (over 90 liters per minute).
The maximum water flow of the 12-volt BACOENG DC Farm Pump is on par with the BACOENG DC 12V Pump flow rate. However, the 24-volt BACOENG DC Farm Pump surpasses both of them. Still, none of them produces as much water flow per minute as the Amarine Made DC 12V Farm Pump.
Now, you might be wondering why we have two BACOENG solar pumps with similar specifications on the list. Well, while most of their specifications are the same, the materials they are made with differ. Consequently, their durability and resistance to corrosion differ.
Of the two products, the BACOENG DC Farm Solar Pump offers relatively lower durability. It comes with a zinc-plated, a rubber gasket, an aluminum filter screen, a plastic impeller, and iron screws. While all of these materials offer decent levels of corrosion resistance, wear, and impact, they are not just as resistant as the materials the BACOENG DC 12V Solar Pump is made of. Unsurprisingly, the BACOENG DC 12V Pump is relatively more expensive than the BACOENG DC Farm Solar Pump.
The maximum lift of the BACOENG DC Farm Solar Pump is capped at 20 feet. This lift is the same as what the BACOENG DC 12V Solar Pump offers. However, it falls short of the ECO-WORTHY Solar Water Pump, the ECO-WORTHY 12V DC Submersible Deep Well Pump, and the Amarine Pump offer. Nonetheless, it is a decent lift distance.
Without a doubt, both variants of the BACOENG DC Farm Solar Pump are efficient. In fact, the 24-volt variant comes with an efficiency rating of 0.8 – pretty high. But while the 12-volts and 24-volt pumps of this brand are efficient, they are still not as efficient as the Amarine Pump.
The efficiencies of these products are inferable. Both BACOENG DC Farm Solar Pumps have a power rating of 120 watts. Then they produce 20 and 24 gallons per minute – which is pretty impressive. But for about the same power, the Amarine Pump can produce 26.4 gallons per minute. Hence, the relatively higher efficiency.
Overall, the efficiency, flow rate, and easy maintenance of this product contribute to its wide applicability. It can be used for farm irrigation, aquaculture, grazier, and much more.
The BACOENG DC Farm Solar Pump can run on solar panels and batteries. But, disappointingly, it does not come with a solar panel or a battery. So, you should get that separately.
For the 12-volt variant, the minimum voltage of the battery system should be 12 volts, and for the 24-volt variant, the minimum voltage should be 24 volts. Besides checking out the voltage of the battery, check out the capacity. Battery systems with low capacity will not power your pump for too long in the absence of direct sunlight.
- Both voltage variants have high flow rates – only bettered by that of the Amarine Pump.
- The pump is pretty efficient.
- The maximum lift is okay, but it is far below the lifts of the ECO-WORTHY solar pumps.
- The package features no solar panel or battery.
- The durability can be better.
BACOENG DC 12V Solar Water Pump
More than just offering a high flow rate, the BACOENG DC 12V Pump offers durability and efficiency.
Unlike the other BACOENG pump, the BACOENG DC 12V Pump only comes with a 12-volt rating. However, the BACOENG DC 12V Solar Water Pump and the 12-volt variant of the other BACOENG pump have the same water flow rate – 20 gallons per minute (75.7 liters per minute).
While a flow rate of 20 gallons per minute is excellent, the Amarine pump and the 24-volt variant of the other BACOENG pump trump this performance. Nonetheless, it gets one over the two ECO-WORTHY solar water pumps.
Like the BACOENG DC Farm Pump, the BACOENG DC 12v Pump can lift water through a maximum height of 20 feet. While this value is fair, it still falls short of what the two ECO-WORTHY solar pumps offer.
The two BACOENG solar water pumps may be similarly matched when it comes to flow rate, maximum lift, power consumption, and other specifications. However, the distinction lies in their durability.
The BACOENG DC 12V Pump comes with a stainless steel body, a stainless steel filter screen, NBR gasket, stainless steel impeller, and nickel-plated screws. However, the BACOENG DC Farm Pump comes with a zinc-plated, a rubber gasket, an aluminum filter screen, a plastic impeller, and iron screws.
Obviously, when compared with each other, the materials used in making the BACOENG DC 12V Pump offers more resistance to corrosion and wear than those used in making the BACOENG DC Farm Pump. Nonetheless, they both find similar applications in farm/small garden irrigation, grazier, aquaculture, and much more.
Pushing out 20 gallons of water per minute while consuming around 120 watts says a lot about the efficiency of this pump. And while it is highly efficient, the Amarine Pump and the 24-volt BACOENG DC Farm Pump edge it out a bit.
Solar panels are the primary power source of the BACOENG DC 12V Pump. But in the absence of solar power, this powerful pump can run on a 12-volt battery. Unfortunately, there is no solar panel, controller, or battery in the package. So, you will have to get them yourself.
- It has remarkable durability. At least it is more durable than the BACOENG DC Farm Pump.
- The flow rate is pretty high – the third-highest of any product on the list.
- The maximum lift is fair.
- The package does not include a solar panel, battery, or controller.
- The maximum lift can be higher.
ECO-WORTHY 12V DC Submersible Deep Well Pump
Last on our list of best solar pumps is the ECO-WORTHY 12V DC Submersible Deep Well Pump. This potent water pump offers high maximum lift, durability, and power source flexibility. But beyond the said features, it also offers a remarkable flow rate.
With the ECO-WORTHY 12V DC Submersible Deep Well Pump, you can push water through a height of 230 feet. Only the ECO-WORTHY Water Pump Kit System matches this capacity. Every other product in this review offers a maximum lift that is at least 7 times less than the lift of these 2 products.
On durability, most parts of the ECO-WORTHY 12V DC Submersible Deep Well Pump are made from 304 stainless steel. So, the pump is unlikely to get corroded or dented easily. Plus, it has a 50 mesh made of stainless steel, which does enough to prevent clogging.
The ECO-WORTHY 12V DC Submersible Deep Well Pump is efficient to an extent. However, the combination of a precision bearing and a pure copper motor sees that this pump uses most of the power it gets to drive the flow of water.
Nonetheless, compared to the other products in this review, the ECO-WORTHY 12V DC Submersible Deep Well Pump is not the most efficient. In fact, it is less efficient than the two BACOENG pumps and the Amarine Pump. But its efficiency is about the same as that of the ECO-WORTHY Water Pump Kit System.
The ECO-WORTHY 12V DC Submersible Deep Well Pump can pump out a maximum of 3.2 gallons per minute (12 liters per minute). This is decent. It is not the highest you can get from a product in this review – the flow rate of the Amarine pump is about 8 times the flow rate of this product.
While solar power primarily drives the operation of the ECO-WORTHY 12V DC Submersible Deep Well Pump, it can also run on electrical energy on batteries, and it can be corded electric. Although, the other pumps in this review run on solar power and batteries too. They cannot be corded electric.
With the power source flexibility the ECO-WORTHY 12V DC Submersible Deep Well Pump offers, you have two ways to keep your pump running even without direct sunlight. First, however, you have to get the solar panel and battery to power the pump because none of these is included in the package.
- The lift is impressive – the highest alongside the ECO-WORTHY Water Pump Kit System.
- The pump can be powered by solar panels and batteries, and it can be corded electric.
- It is relatively durable.
- The flow rate can be higher.
- Batteries and solar panels are not included in the package.

Buying Guide for Solar Water Pumps
Features to Look Out For in a Solar Powered Water Pump for Irrigation
The flow rate of a water pump is a measure of the volume of water it can push out per unit time (usually per minute), and it differs from one pump to another.
For each type of irrigation, there is a desired flow rate. In other words, some pumps may not push water out at the rate you need it for your irrigation. Therefore, confirm the desired flow rate for your type of irrigation, then check that the product you choose meets this requirement or exceeds it.
The maximum lift of your pump tells you the maximum vertical distance your pump can push water from the water source to the drainage source. This value is vital if the drainage source or destination of the water stands at a spot way above the ground.
Your pump must be able to push water through the height between the water source and the water destination.
Solar Panel Capacity
Understandably, solar pumps need PV panels to function. But the pumps can only function if the solar panel generates enough power to get them running. If your pump comes with a PV panel, you will not have to worry about the panel capacity.
However, if you have to buy the panel separately, you must pay attention to the PV panel capacity.
To ensure you get things right, verify the wattage of your pump before getting the solar panel. Ensure that the panel produces at least the same power as the rating of the pump. You can do one better by getting a panel that produces more power than the power rating of the pump. This way, you will not have to worry about power loss.
Solar Water Pump Efficiency
With all types of machines, efficiency is crucial. Efficiency defines the extent to which a machine uses the power it gets.
A low-efficiency machine will waste most of the power it gets and produce little output in simpler terms. On the other hand, a high-efficiency machine will use most of the power it gets to generate output.
In the same way, a solar-powered water pump with high efficiency will maximize the energy it gets from the sun and channel most of it into pumping water for irrigation. In other words, with an efficient pump, within the short period sunlight hits the PV panel, you would get a high level of water circulation.
Resistance To Corrosion
With the constant exposure to water and air irrigation, the metallic parts of a solar-powered water pump are at risk of corrosion. Luckily, some metal alloys like stainless steel are plated to resist corrosion.
When getting a pump, be on the lookout for one with parts built to resist corrosion. In many cases, pumps made with stainless steel are your best bet.
Power Source Flexibility
Powering your pump with the energy from the sun is eco-friendly and all. However, the sun will not always be around. When the sun does not shine, you might be unable to power the pump, except it can run on other power sources.
Thankfully, various solar water pumps can run on more than just energy from the sun. Some use batteries, while some can be corded electric.
Are Solar Powered Water Pumps Any Good?
Solar-powered pumps are pretty effective for various types of irrigation: small garden irrigation, farm irrigation, and much more.
Beyond being an effective means of irrigation, solar pumps have a low operating cost compared to their alternatives. This is because they run on solar energy, and you do not have to pay for that. The operating costs you will incur while using solar pumps will most likely come from maintenance and repairs.
Besides, since these pumps rely on the power generated when sunlight hits a solar panel, you never have to worry about a rise in your electricity bills. At the same time, they are eco-friendly since the sun is a renewable source of energy.
How Many Solar Panels Does It Take Power a Water Pump?
The number of PV panels needed to power a water pump depends on the wattage of the pump.
For instance, if you have a 100-watt pump, you need at least a 100-watt solar panel. However, it is advisable to get a solar panel with a slightly higher power output to make up for any power loss.
Going by the instance above, if your pump is rated 100 watts and your solar panel is rated 50 watts, it will take at least 2 of such solar panels to power the pump.
How Much Solar Energy Does My Solar Water Pump Consume?
The amount of solar energy your water pump consumes is a function of its power rating and how long you keep it running.
For instance, if your pump is rated 100 watts, and you leave it running for 2 hours, the maximum solar energy it can consume within that period is 200 Wh or 0.2 kWh.
Beyond being eco-friendly, a solar-powered water pump for irrigation is certainly effective at what it does. But to ensure what you get works for you, ensure you opt for a product with a flow rate that suits your needs. Then, be sure to verify the product’s capacity, durability, flexibility, ease of maintenance, ease of installation, lift, and efficiency.
