Main Benefits of Solar Pond Pumps
As the name suggests, a solar powered pond pump just requires energy from the sun to work. Solar rays will hit the pump’s solar panels and then be converted into electricity. The more sunlight you get, the better your pump will run!
The biggest single benefit of a solar pump for most pond owners would be the lack of monthly running costs. So long as you get a sufficient amount of sunlight each day, the pump will be able to function autonomously, without even needing to be wired to your mains socket.
Solar pumps are also very discreet, quiet in operation, and usually powerful enough to run smaller water features without trouble. If you live somewhere with plenty of months of sunlight, it can be a great (and cheap) addition to your garden pond.
To top it off, solar power is environmentally friendly and considered a green energy source. Renewable energy is the way of the future, and every little bit helps!
Main Drawbacks of Solar Pond Pumps
Sadly, these kinds of pumps do have some drawbacks and are not suitable for all pond features and situations.
The first major drawback is the lack of water flow and head height these kind of pumps can produce. Generally speaking, a “powerful” solar powered pump will be in the range of 100-200 GPH of water flow. This would not be sufficient in powering a pond filtration system, or as a main pump for a large water feature.
Solar pumps have not been designed to replace a regular pond pump, but are used to help power small features so you don’t need a separate pump attached to the mains. They are usually purchased as ‘kits‘ with a specific purpose in mind, such as powering a small fountain or aerator, and should not be confused with stronger electric models that are designed for heavier operation.
Another drawback is the limitations of a solar pumps battery capacity. During the day, sunlight is converted via the solar panels and stored as energy within a rechargeable battery pack if one is included. When the sunlight fades, the stored battery energy will have to take over. Depending on the efficiency and size of the battery, there may only be enough energy for a few hours of operation.
Different Types of Solar Powered Pumps (Water & Air Pumps)
1) Solar Fountain Pumps
The most common type of solar pond pump is the fountain pump, which usually comes with both pump and fountain head included. These pumps are designed to be placed on the pond floor with the fountain attachment above the surface of the water. The solar panels will be connected to the pump and will power the fountain using the days’ sunlight.
Although you won’t get a huge amount of water height here, solar fountains are surprisingly effective and great as smaller pond features. Since a certain depth is required for an optimal display, they may not be suited for deep ponds and often work best on shallow pond banks.
2) Solar Air Pumps (Solar Aerators)
Another type of common pump is the solar air pump, which is used to provide extra aeration (oxygenation) to your pond water. They function the same as a fountain pump, with both solar panels and a battery for collecting charge. Instead of powering a water feature, though, they act as a simple method of adding oxygen to your water. If you do not have a water feature in place, such as a fountain or waterfall, having an extra means for oxygenation may be helpful. This is especially true if you have a pond stocked with fish, as more dissolved oxygen will improve fish health and water quality.

Finding the Perfect Solar Pond Pump (Considerations)
When looking for a solar powered pump, there are several points to consider before investing so you’re not disappointed with your purchase. Things you’ll need to ask yourself are below:
Is it powerful enough?
The first question you should ask is if the pump is powerful enough for its intended purpose. If you have a 2000 gallon pond, for example, a 200 GPH solar pump will not be sufficient as a main pond pump. If you want to add a small 3ft fountain to your 300 gallon pond, however, a solar powered fountain pump may be the perfect solution.
In general, most solar powered pumps are designed for ponds of a maximum size of 1000 gallons, but can also be used in larger ponds as a complementary feature so long as they’re placed on a shallow shelf.
Do I get enough sunlight?
Without sunlight, solar pumps just won’t work! You’ll need to make sure you can set the solar panels in an area which catches a good amount of daily sun for maximum benefits. On overcast days, if your pump has a battery included, you can also let the batteries keep the pump running while you wait for the sun to return.
Solar panel and battery quality?
Solar panels need to be manufactured to a high quality standard, and the larger the panel’s size, the more power will be produced!
For your solar pump to keep running at night and on overcast days, you’ll also need a solar battery with adequate charge. From experience, after a full day of sunlight, a good battery should provide around 3-5 hours of further use before the charge is depleted. If the pump kit doesn’t come with a battery pack included, you can purchase one separately and attach to the solar panels fairly easily.
Ways to increase the efficiency of a solar pond pump:
There are a few ways to increase the efficiency of a solar pump so you can get maximum benefits. Some of these are:
- Placing solar panels to catch the strongest sun (11am-3pm)
- Cleaning solar panels regularly
- Cleaning solar pump regularly
- Decreasing fountain height
- Improving water quality (less pump work)
Best Solar Powered Pond Pump Reviews 2022 (Top Models Compared)
Due to the different brands available between the US and UK markets, we’ve researched and divided our categories to provide both American and UK pond owners a review on the best solar powered pond pump available. We have listed below our recommended solar fountain pump picks available to both the US and UK market.
US - Best Solar Pumps
A simple and fairly powerful solar pump kit with a generous solar panel size. Lewisia’s Solar Pump kit features a 300 GPH solar pump connected to a 10W Mono-crystalline solar panel. The solar panel is attached to a sturdy steel frame which provides support and easy positioning. The frame allows for 3 angles of positioning, or can be placed flat against a surface of your choice. If using the frame the angles should provide good options for sunlight exposure, but a few more sharper angling options would have been ideal.
The pump is fairly powerful for a solar pump, and will start working after around 3-5 seconds of bright sunlight collection. We tested this model within a small 200 gallon fish pond and placed it on a shallow shelf. The fountain obtained a good amount of height, and flow was strong while the sun was constant. The fountain height is adjustable, and comes with 6 different head attachments for different fountain displays. They are quite fiddly to attach, but work surprisingly well.
This solar pump kit doesn’t come with a battery, however, so there is no option for powering without constant sunlight. It will only work when in direct sun, and will simply turn off during the night or when heavily overcast.
With that said, this is still a very good choice for pond owners who want a compact but fairly powerful pump with a good fountain display height. It would work great in ponds up to 500 gallons, or in larger garden bird baths.
- Solar Panel: 10 watts
- Pump Strength: Approx 300 GPH
- Max water height: 5 ft
- Battery operation: No battery
A fantastic solar powered fountain pump kit with a large rechargeable battery pack system and bright LED fountain lights. The Sunnydaze solar package provides everything you need to get started with a solar powered water display, including a pump rated at 132 GPH, a 4 hour battery pack, multiple fountain attachments, and a 5 watt solar panel display. Even though the panel is fairly small in comparison to some other models, it still packs a decent punch under full sunlight, being able to provide a 4.5 foot water display on full battery charge – great for smaller ponds, bird baths, or extra aeration!
One of the best aspects about this kit is the very large (by solar standards) battery pack that provides up to 4 hours of runtime during twilight and overcast periods. In strong sunlight, the battery will charge slowly through the solar panel, and once full, will switch on automatically when sunlight becomes too low to power the fountain directly.
The battery unit also has a convenient control panel and indicator lighting system, providing options for setting a daily timer or alternating the flow rate of the pump for a specific height of water display. If you want to run your fountain display after hours, this kit would be a solid choice as it has one of the longest lasting battery packs we’ve seen on a solar model.
In terms of accessories, two 16 foot cables are included to connect the pump and the battery pack together, as well as four different fountain heads for different water displays. Another benefit of this particular kit is the inclusion of a bright LED light which attaches just under the fountain head. The light does a great job of making the fountain look more alive at night, but it won’t likely be enough to illuminate much more than the solar display itself – but it’s a nice addition nonetheless! A great solar kit if you want maximum twilight operation, lots of fountain display options, and some lights to make things more vibrant.
- Solar Panel: 5 watts
- Pump Strength: Approx 132 GPH
- Max water height: 4.5 ft
- Battery operation: Approx 4 hours
Solarriver’s Solar Fountain pump is one of the more powerful solar pumps we have used, being able to output close to 400 GPH at max voltage. This solar pump kit would be perfect for pond owners who want a slightly larger fountain, or need some extra power from their pump. The pump itself is fully submersible and comes with a removable filter to help prevent clogging.
The 20 watt poly-crystalline solar panel is quite large and capable of producing decent output when the sun is bright. There is no frame for angling options on this unit, so you would need to place the panel flat on a surface in good sunlight. The cable is quite long (16ft), however, so it should be fairly easy to get the panel in a good position.
The panel comes with a very small battery on the back which holds some charge after the sun fades, but we found this very underwhelming. Unless you have had a full day of constant, strong sunlight the battery will not be able to power the pump for long. If you want to use this during the night, we recommend attaching a larger battery separately.
With that said, in terms of solar power, the pump is one of the strongest we’ve tested and the solar panels are large enough to produce a good amount of current. An ideal solar option for both small and medium ponds looking for a cost effective solar fountain pump with very good water lift heights.
- Solar Panel: 20 watts
- Pump Strength: Approx 400 GPH
- Max water height: 6.5ft
- Battery operation: Approx 1 hour
A very powerful solar powered fountain pump kit which comes with solar pump, multiple fountain heads, integrated battery AND LED lights! The Primrose solar pump kit operates at a mighty 1200 LPH and can create a fountain display of several meters on a full battery charge. The pump is powered by a high quality 10 watt solar panel which is also attached to a battery pack providing up to 5-6 hours of operation after a good day of sunlight. The pump comes with 4 different fountain head displays as well as sturdy plastic stakes to secure everything in place.
Alongside the powerful pump and long-lasting battery pack, the kit also comes with 5 LED lights, as well as different mods of operation so you can customize the display. The lights provide a fantastic backdrop to enhance the fountain itself, and since they’re solar powered, they won’t cost you a penny extra to run! The battery is also one of the best we’ve seen, which switches on automatically during low-light conditions and holds a considerably long charge for its small size, allowing up to almost 6 hours of night-time/overcast operation. There is even a dedicated “winter mode” (something we’ve not seen before!), which optimizes the panel for winter/low-light conditions and allows a continuous display all year around.
The solar panel itself is sturdy, durable and can be easily positioned anywhere in the garden using the spikes provided. Set-up overall is incredibly easy, and all attachments fit neatly in place. The solar panel does best in a position of high sunlight, so make sure to take this into account when installing if you want that maximum water height the kit offers.
Overall, this 1200 LPH pump is powerful enough a large water display, and would be best suited for medium-large (300-1000+ litre) ponds, koi ponds (extra aeration is always great!), or pond owners looking for a large solar display without breaking the bank. If you also want maximum twilight operation, the battery pack is one of the best we’ve seen, with the solar pond lights being a nice touch to complete the package!
- Solar Panel: 10 watts
- Pump Strength: 1200 LPH
- Max water height: 1-3m
- Battery operation: 4-6 hours
If you need a little more power and a larger fountain height, PondXpert’s SolarShower fountain range are a great choice. The 400 model SolarShower kit comes with a 400 LPH submersible pump with a large 5 watt solar panel display. This pump provides greater water lift height compared most other solar pumps, so would be ideal for pond owners who want a larger fountain display.
The solar panel is sturdy and easy to position, providing plenty of power to the pump on a bright day. The kit comes with a 9v rechargeable lithium battery which provides around 2-4 hours of operation on full charge. The solar panel also has illuminated LED lights that automatically switch on during the night, which is a nice touch.
Even though the fountain provides good height for a solar pump, it cannot be positioned deep (approx. 20 inches), so you will need to take this into account before installing.
Overall, PondXpert’s SolarShower fountain kit provides a great solar pump option for pond owners who require a larger water display and more power.
- Solar Panel: 5 watts
- Pump Strength: Approx 400 LPH
- Max water height: 1.4m
- Battery operation: Approx 2-4 hours
A fantastic UK solar pump offering comes from Hozelock’s Solar Cascade fountain pump. The pump has a fairly large solar panel which powers its 300 LPH submersible fountain pump.
The solar panel is attached to a plastic stake for positioning, and the pump comes with a single fountain attachment head. The pump is not the strongest we’ve tested, but we love the efficiency of the solar panel and battery pack. The solar panel is very high quality and provides a decent amount of power when the sun is bright. The kit also comes with 4x rechargeable batteries for operation during overcast days or nighttime. The batteries are reliable and provide a good 3-5 hours of operation on a full charge, which is really decent for a solar pump.
When operating under full sun, the pump is capable of a maximum fountain height of 1.1 meters, which is a good height for smaller ponds. The pump also comes with a 1 year full replacement warranty for peace of mind.
Overall, a great solar pump choice with a good battery pack for twilight operation and solid water lift heights.
- Solar Panel: 1.6 Watt IPx4
- Pump Strength: Approx 300 LPH
- Max water height: 1.1m
- Battery operation: Approx 3-5 hours
