How Do Solar Well Pumps Work?
The sun recycles about a trillion gallons of water every day through the process of evaporation and precipitation. Surely it’s only natural, therefore, that its energy should also be used in the pumping of water from wells bored deep into the ground, or in swimming pools and rain barrels, for the use of homes and rural farmsteads? That, at least, is the thinking behind the solar well pumps reviewed and rated in this article.
Still, you’re probably wondering: how do solar well pumps work? Even if you’re familiar with the mechanics behind the operation of pumps, you might be confused as to how solar technology fits in. Whether you’re a novice or a sage of well pumping, we’re here to illuminate for you the inner workings of solar technology.
First, the pump itself. All of the pumps on this list are ‘submersible’ pumps which, as the name suggests, are submerged beneath the surface of the water, deep at the bottom of the well. Submersible well pumps are sturdy, cylindrical metal objects housing a motor and a set of impellers. Water filters into the pump through holes in the housing, and the motor then drives the encased impellers which push this water up through attached pipes into your house or farm’s water tank.
Sensors are another integral part of the pump’s operation. Placed in the water of the well, and in the residential water tank, they effectively instruct the solar well pump setup as to when the water tank requires more water from the well, and when the well requires time to naturally refill, before it can be mined again for water. These sensors are connected to the solar controller, which is in charge of conducting the whole operation.
And what else is connected to the solar controller? Well, there’s only one thing left… the solar panels, of course! Solar panels may look complicated, but in reality they are fairly straightforward contraptions. Comprised of many individual photovoltaic cells, housed in a weather and waterproof, UV-resistant casing, they are made of polycrystalline or monocrystalline silicon. This silicon, when exposed to the sun’s rays, reacts both chemically and physically in a process known as the ‘photovoltaic effect’. Essentially, the reaction converts sunlight into consumable electricity, which the panel then feeds, in the case of solar well pumps, into the solar controller and the pump itself.
Alternatively, solar panels can be first attached to batteries, which are then attached to the controller and pump, allowing for the pump’s operation overnight, when the panels are inoperable due to the lack of sunlight. However, whether you attached the panels to a battery first or not is at the discretion of the user: either setup works just fine. The controller ensures that the energy produced by the solar panel(s) is optimised for the voltage and wattage required by the pump.
Pros and Cons of a Solar Well Pump
As with all modern technology, there are both advantages and disadvantages to installing a solar well pump on your property. Let’s take a look at the most fundamental of the pros and cons.
- Free electricity. Sunlight doesn’t just come cheap, it comes completely free. Thus, whilst the initial investment in solar technology might seem steep, you’ll pay it all off and then some after you begin saving on your electricity bills. Pumping water is a necessity and a lifeline for many rural dwellers, and having free electricity to do so with can make all the difference.
- Water even in an outage. Unlike grid-electricity, which during a power outage would be unavailable, thus rendering your water pump broken, solar energy will never (in our lifetimes) run out. Thus, solar well pumps are the only guaranteed alternative to grid power in an outage (or indeed, in the likelihood that you don’t have access to grid power, due to your location).
- Automatic operation. With many solar well pump kits, you get a controller and sensors included. These sensors ensure that your water tanks are kept at the levels required, whilst your well is never drained dry. The solar controller, on the other hand, ensures that this operation runs smoothly and is maximised for efficiency.
- Green and eco-friendly. Instead of using fossil fuel electricity, which is terrible for the environment, you can use environmentally-friendly renewable energy and not have to worry about the effect your pumping is having on the environment.
- Wide application. Whilst solar well pumps may be intended for pumping water into your property’s water tanks from a well, they don’t have to be limited to this application. In fact, they can be used to displace water in many situations, including in emergency situations such as floods.
- High maximum lift and flow rate. Solar power doesn’t have to mean less power. With the pumps on this list, you can still meet high lift requirements (the height water needs to be pumped to from the base of the well), and achieve high flow rates (the amount of water being pumped per hour).
- Sunlight depending. As with all solar powered technology, the smooth operation of solar well pumps depends upon the solar panels’ consistent exposure to sunlight. Ensure that your solar panels are placed so as to maximise their daily sunlight exposure. Unfortunately, if you live in an area which is often overcast, or in which sunlight is not dependable, you may experience issues with your solar well pump’s efficiency and overall operation.
- Solar panels not (necessarily) included. Unfortunately, few solar well pumps come with the solar panels included, leaving it up to you the consumer to locate and purchase panels strong enough to do the job.
- Expensive. Given that you’ll likely have to purchase solar panels separately, the expense associated with solar well pumps can be quite high. Still, given the eco-friendly, long-lasting, and dependable nature of solar technology, and the fact that it will save you tonnes in energy bills, we still think the investment’s well worth it.

Solar Well Pump Buyers Guide
As previously mentioned, selecting the correct well pump is critical in order to optimize its usage and avoid wasting money on a well pump that isn’t right for your well and ending up with a disappointing device. Here are a few factors to keep an eye out for when buying a well pump:
Maximum lifting height
Examine the maximum lifting height, also known as “the maximum head,” to ensure that it is appropriate and compatible with your well. If you buy a water pump with a maximum head of 195 feet/60 meters, the flow rate would be zero if you want to pump water to heights greater than that. Generally, the pump you choose should have a maximum head that is higher than the height at which you plan to pump the water.
Flow rate refers to the time taken by a water pump to pump a specific amount of water. If you are going to use the water pump for either job sites or farms, you should purchase one that has the ability to pump over 2500 liters/660 gallons of water per minute. On the other hand, a pump with a flow rate of between 100 – 200 liters/26-52 gallons per minute is ideal for any home use. If you’re someone who prefers having a steady and fast flow of water, it is always best to pick a well pump that pumps out more liters per min.
Price And Quality
It’s important that you spend your money according to the quality of your solar pumps. Some well pumps may be unnecessarily expensive for products that have a slow flow rate and a limited maximum lifting height, or just poor quality products in general. Due to this, it is important to do thorough research on your well pumps before buying them. For example, reading reviews and researching the brand are both essential steps in ensuring you do not receive a disappointing product or pay too much for a product of poor quality. If a solar pump kit is out of your price range, there’s no need to worry. There are many options for you to choose from, so take your time and you may just find the perfect well pump to suit your needs, so keep looking!
Taking into account the pumping systems mentioned above, the PWS 24V Stainless Steel 316 solar pump kit is our recommendation. It has a high maximum lifting height and a strong flow rate. It is also a high-quality product that is well worth the money and if any problems in regards to the quality arise, it will be covered by the manufacturer.
