How to Choose a Water Submersible Pump for Your Needs
If you are asking yourself how to choose a water submersible pump, the key is to match the pump to your water source, usage needs, and budget. A submersible pump is a reliable way to lift water from wells, reservoirs, or rivers, but choosing the wrong model can lead to poor flow, higher costs, and ongoing frustration.
How a Solar Submersible Pump Works
A solar water pumping system has three essential components:
-
Solar panels that capture sunlight and convert it into electricity
-
A controller that regulates power flow and protects the pump
-
The submersible pump itself, which draws water from your well or source
During daylight hours, the pump delivers steady performance. For nights or cloudy days, water is stored in tanks or reservoirs to ensure a reliable supply. The U.S. Department of Energy provides a useful overview of solar water pumping basics.
Key Factors in How to Choose a Water Submersible Pump
When selecting a pump, keep these factors in mind:
-
Well depth – shallow wells may only need standard pumps, while deeper wells require submersible pumps designed for higher head pressure.
-
Daily water demand – estimate how much water you need per day to size your pump and solar array correctly. The FAO guide to solar irrigation explains how to calculate water requirements.
-
Water quality – if filtration or treatment is necessary, make sure the system can handle it.
-
Budget – stainless steel pumps with MPPT control and dry-run protection may cost more upfront but last longer and save money over time.
Installation and Maintenance Tips for Submersible Pumps
Proper installation ensures long-term performance. Place solar panels in full sunlight, secure wiring, and add a storage tank to guarantee water at night. While some systems are DIY-friendly, professional installation is best for deeper wells. Maintenance is simple: clean panels regularly, inspect fittings, and check the pump for signs of wear. The National Renewable Energy Laboratory offers additional solar system resources.
Why a Solar Submersible Pump Is a Smart Choice
Choosing the right solar submersible pump provides more than just water. It lowers energy costs, reduces reliance on the grid, and delivers a dependable supply for homes, farms, and irrigation systems.
