Buying guide
Choosing the Right Solar Well Pump for Your Property
Three numbers define the right pump: well depth, flow rate needed, and peak sun hours at your location. Use this table to narrow your search before you buy.
| Use Case | Well Depth | Recommended Type | Typical Flow | Solar Panel Needed |
|---|---|---|---|---|
| Cottage seasonal water | Under 25 ft | Solar Shallow Well Pump | 3–8 GPM | 100–200W |
| Rural home year-round | 25–150 ft | Solar Submersible Well Pump | 5–10 GPM | 200–400W |
| Farm / livestock watering | 25–200 ft | Solar Deep Well Pump | 8–20 GPM | 300–600W |
| Off-grid cabin, battery system | Any | 12V Well Pump | 2–5 GPM | Existing 12V bank |
| DIY, first solar install | Any | Solar Well Pump Kit | Varies by kit | Included in kit |
GPM = gallons per minute. Solar panel wattage assumes 4–5 peak sun hours/day, typical for most of Canada May–September. Contact us for winter sizing or northern Canada recommendations.
Common questions
Solar Well Pump FAQ
How does a solar well pump work?
A solar well pump uses DC electricity generated by solar panels to drive a pump motor. During daylight hours, the solar panel powers the pump directly. A pump controller regulates voltage and protects against dry-run or low-voltage conditions. Water is pumped into a storage tank so your household supply is available even after dark or on cloudy days.
What size solar panel do I need to run a well pump in Canada?
A typical residential solar well pump requires between 150W and 400W of solar panel capacity depending on well depth and flow rate. In Canada, plan for a slightly oversized panel array to compensate for shorter winter days and panel soiling from snow. A 200W panel is a common starting point for shallow-well cottage applications; deep-well farm pumps often need 400W+.
Can a solar well pump work in winter in Canada?
Yes, with proper setup. Submersible solar well pumps are inherently freeze-resistant because the pump stays below the frost line. The solar panel still generates power on clear winter days, though output is reduced. Many Canadian off-grid homes pair the pump with a battery bank or backup generator to ensure water supply during extended overcast periods.
What is the difference between a solar deep well pump and a solar shallow well pump?
A solar deep well pump (submersible) is designed for drilled wells 25 feet or deeper and sits submerged in the casing. A solar shallow well pump (surface-mount or jet pump) is suited for dug wells or surface water sources within 25 feet of the pump. Deep well pumps are more efficient at high lift heights; shallow well pumps are simpler to service.
Do I need a battery to run a solar well pump?
Not necessarily. Many solar well pump systems run directly from the panel with a storage tank acting as the buffer — water is pumped when the sun shines and stored for use at night. If you need on-demand water pressure at any hour, adding a 12V battery bank and pressure tank gives you grid-like reliability without a generator.
What is the best solar well pump for Canada?
The best solar well pump for a Canadian property depends on your well depth, flow demand, and whether you need year-round or seasonal operation. Submersible 12V pumps with brushless motors are popular for their durability in cold climates. Rock Solar carries a curated selection sized for Canadian conditions — contact our team if you need help matching a pump to your well specs.
