Submersible Solar Well Pumps: Efficient and Cost-Effective Water Solutions

Submersible pumps are an innovative solution that can provide a reliable and cost-effective way to pump water from wells. These submersible pumps are designed to be submerged in deep water wells (up to 800 ft deep) and use solar energy to power the motor, which drives the pump. 

They are ideal for remote locations where access to electricity is limited or nonexistent. With the right types of installations, such as diaphragm, centrifugal, or helical water pumps, you can significantly improve water access in deep wells.

Submersible pumps are an excellent choice for those looking for a reliable and sustainable way to pump water from deep wells. They offer a cost-effective and environmentally friendly alternative to traditional electric water pumps, making them attractive for those looking to save on energy costs or just looking to reduce the pull on their off-grid system (these pumps can use a fraction of the wattage for the same output).

Easy to Install for the DIYer

You’ll need the right equipment types based on the well's deep requirements. Reference manuals are crucial for determining the proper installation and ensuring you have all system components marked out.

If you have a higher deep lift, need more water, or want a pump that does not require service for 10 to 20 years, the Grundfos SQFlex solar well pumps are a good choice. The SQFlex solar pump can lift water over 820 feet and can pump over 90 Gallons per minute (GPM) at lower lifts.

Our Favorite Submersible Pumps

Various submersible pumps on the market handle different types of water demands and deep well installations.

• Aquatec SWP Series Submersible Pumps are designed to be efficient and reliable for off-grid applications. These submersible pumps are made of high-quality materials that are resistant to corrosion and abrasion. They come in varied types and are efficient and reliable for off-grid, deep well solutions up to 230 ft of total dynamic head. They have a steel construction, are American-made, and can can run off of a 12v or 24v battery system or directly off solar panels.

• Shurflo 9300 Solar Well Pumps are another popular option for off-grid water pumping. These water pumps are designed to be energy-efficient and reliable, making them suitable for deep wells up to 230 feet of total dynamic head with a maximum flow rate of ~2 GPM with low-light references on efficiency.

• Grundfos SQFlex Solar Well Pumps are a premium option for off-grid water pumping. They are more powerful, require less maintenance, and can work at deeper depths with higher flow rates than either of the above alternatives. These submersible pumps are designed to be highly efficient and reliable, making them suitable for demanding applications and solid deep well pumps with resilience and adaptability for multiple solar types. Versions of these pumps can produce 50-100 GPM at low head levels and other versions can still produce 5GPM at depths up to 820 feet. There is likely an option in this line for your use case.

Each of these water pumps has unique features and benefits, so choose the one that best suits the total dynamic head and water flow requirements of your well project.

Frequently Asked Questions

How long do submersible solar water pumps typically last?

On average, a well-maintained submersible solar water pump can last anywhere from 10 to 20 years, depending on the brand, water conditions, and frequency of use. Proper installation, well water quality, and regular maintenance play a key role in extending the lifespan of the pump.

Can submersible pumps be used in freezing temperatures?

Submersible pumps are typically located deep underground, where the temperature remains stable. However, if your location experiences freezing temperatures, you will need to ensure that external pipes or above-ground components are insulated to prevent freezing and may want to consider using a pitless adapter.

Is it possible to connect submersible solar water pumps to a backup generator?

Yes, many submersible solar water pumps are compatible with backup generators for use during long periods of insufficient sunlight. The Grundfos SQFlex pumps can run directly off of a generator.  But Shurflo and Aquatec pumps would need to be run through a battery system that is being charged by the generator.
