Solar PV systems are becoming more popular all the time, but one of the big questions people have about them is how to run a well pump on solar.
This article will answer that question and more, detailing everything from what types of solar PV systems work best for running a well pump on solar, to how you can calculate your system’s power output and make sure you’re meeting your energy needs.
What is Solar Well Pumping?
Solar well pumping is a process of using solar energy to operate water pumps.
The Solar Well Pumping Association (SWPA) was founded in 1978 as the first national organization dedicated to promoting and advancing solar well pumping. SWPA members include manufacturers, distributors, resellers, service providers and consultants who work together to promote and support solar well pumping technology and its applications.
Solar well pumping is becoming an increasingly popular option for remote communities that rely on clean water supplies. According to the SWPA, there are over 1,000 solar well pumps in operation around the world.
The primary benefit of solar well pumping is that it uses very little fuel or electricity. Solar wells pumps are typically powered by photovoltaic (PV) cells or batteries, which can remain operational even when the grid is disrupted. Additionally, solar well pumps can be used in areas with low sunlight availability or when there is no access to power grids.

Types of Solar Pumping Systems.
If you’re thinking about powering your well pump with solar energy, there are a few things to consider. Here we’ll explore three types of solar pumping systems: grid-tie, off-grid and hybrid.
Grid-Tie Solar Pumping Systems.
Grid-tie solar pumping systems are the simplest type of solar pumping system. They rely on connecting your well pump to the grid (via an inverter or a solar panel). When your solar panels generate electricity, your pump will be powered.
There are a few benefits to using a grid-tie system:
You’ll always have access to power. Even if the power grid goes down, your well pump will still be powered by your solar panels.
Your well pump will be powered when it’s most needed – during peak hours when electricity is expensive.
You won’t need any extra equipment – all you’ll need is a compatible well pump and solar panels.
Overall, grid-tie systems are the simplest and most cost-effective way to power your well pump with solar energy. They’re also the least flexible – you can’t use them if you don’t have access to a reliable power source, like the grid.

Off-Grid Solar Pumping Systems.
Off-grid systems are similar to grid-tie systems, but they rely on independent power sources (like solar panels or a battery) to power your well pump.
The main benefit of an off-grid system is that you can use it anywhere there’s sunlight – even if you don’t have access to the grid.
Off-grid systems are also more flexible than grid-tie systems. You can use them even if you lose access to the grid, or if prices increase and the power grid becomes unreliable.
Overall, off-grid systems are a great option for people who want to power their well pump with solar energy, but who don’t have access to the grid. They’re also the most cost-effective option – you won’t need to spend as much money on equipment as you would with a grid-tie system.
Hybrid Solar Pumping Systems.
Hybrid solar pumping systems combine features of both grid-tie and off-grid systems. They rely on a combination of solar panels and batteries to power your well pump.
The main benefit of a hybrid system is that it’s flexible – you can use it even if you lose access to the grid, or if prices increase and the power grid becomes unreliable.
Another benefit is that hybrid systems are often less expensive than either a grid-tie or off-grid system.

Installing Surface well pumps.
Running a surface well pump on solar can be a great option for homes in areas that experience dry spells. Surface well pumps use centrifugal force to move water up and out of the ground, making them a popular choice for properties in areas with shallow soil.
Here are five tips for installing a surface well pump on solar:
1. Get an accurate estimate of your pump’s capacity. A surface well pump’s output is based on its horsepower (or “horsepower rating”), which is determined by multiplying the diameter of the pump’s impeller by the frequency of its rotation. Before you purchase your pump, make sure to calculate its horsepower rating and ensure that it matches the requirements of your system.
2. Estimate your installation costs. To install a surface well pump on solar, you’ll need to account for both the purchase price of the pump and the cost of installation materials, such as wire and stakes. Add these figures together to get an overall estimate for your project budget.
3. Decide which type of installation best suits your needs. There are two main types of surface well pumps: single-stage and multi-stage pumps. Single-stage pumps operate only once and eject water directly into the groundwater supply. Multi-stage pumps can repeat the steps of ejecting water and sucking it back in multiple times, which increases pumping capacity.
4. Consider your system’s layout. When installing a surface well pump on solar, you’ll need to account for the location of your system’s battery, inverter, and water lines. Make sure to plan your installation so that all these components are accessible and easy to access.
5. Employ solar-friendly installation techniques. To avoid damaging your pump during installation, use solar-friendly installation techniques, such as using sun shades to protect your equipment from direct sunlight. Also keep in mind that a surface well pump requires a lot of room to operate properly, so make sure to plan your installation accordingly.
