If your farm, orchard, fish pond, greenhouse, estate or agricultural facility uses water pumps regularly, solar may help reduce electricity costs by offsetting pump operation during daylight hours.
This Solar100 Solar Water Pump Calculator helps estimate the solar system size, installation cost range, monthly electricity savings and payback period for irrigation pumps, farm water pumps, fish pond pumps, well pumps and agricultural water pump systems.
It is suitable for irrigation pumps, water pumps, fish pond pumps, aquaculture pumps, farm pumps, estate pumps, well pumps, booster pumps and agricultural pumping systems.
Solar is usually more suitable for water pumps that run during the day. If your pump operates mostly at night or must run continuously, you may need to evaluate battery, hybrid solar or grid-connected design.
Use the calculator below to estimate whether solar is worth checking for your pump system and send the result to Solar100 WhatsApp for a basic suitability review.
Fill in a few simple details about your pump. The calculator will estimate suggested solar size, installation cost range, monthly savings and payback period.
Your location helps Solar100 check suitable solar pump or agricultural solar installer options near your area.
Your contact number will be included in the WhatsApp message for follow-up.
Different pump applications may need different solar design, especially for aquaculture or continuous water circulation.
If you are not sure, choose “Not sure / Larger Pump” and Solar100 can help check based on your pump photo, nameplate or electricity bill.
Longer pump operation usually requires a larger solar system and may affect backup needs.
Solar pump systems are usually easier to justify when the pump can run during the day.
If there is no grid or backup is required, battery or hybrid design may need to be checked.
After clicking the button, WhatsApp will open with your estimated result. Please review the message and tap send so Solar100 can help check your solar pump suitability.
Suggested Solar Size for Pump:
----
This is a simple estimate only. Actual solar pump design depends on pump starting current, motor type, pressure/head, water flow requirement, pipe distance, pump controller, grid access, battery need, mounting structure and site condition.
Solar can help power or offset electricity usage from water pumps, especially when the pump operates during the day. For farm irrigation, vegetable farms, orchards and estates, pump operation can often be adjusted to match sunlight hours.
However, not every water pump should be designed the same way. A pump that runs for two hours during the day is very different from a fish pond pump or aerator that runs overnight or continuously.
For water pumps, the system must be checked carefully because pumps may have high starting current, pressure/head requirements and flow requirements. If the pump is critical for livestock, aquaculture or irrigation, backup and reliability should be reviewed before deciding on solar.
| Pump Situation | Solar Suitability | What to Check |
|---|---|---|
| Pump runs mostly during daytime | Usually easier to evaluate | Solar size, pump controller, operating hours and water demand |
| Pump can run flexibly when sunlight is available | Often suitable for solar-first design | Water storage tank, irrigation schedule and pump capacity |
| Pump runs at night | Needs closer checking | Battery, hybrid design or grid backup |
| Fish pond or aquaculture pump runs continuously | Needs careful design | Backup, 24-hour load, battery and reliability requirement |
| Remote area without grid | Possible but more technical | Off-grid solar, battery, pump controller and maintenance support |
The cost of a solar water pump system depends on more than pump size alone. A proper solar pump proposal should review the pump motor, water demand, site layout and whether backup is needed.
Some farms only need solar to reduce the TNB bill from pump operation. In this case, normal grid-connected solar may be suitable if the pump operates during the day and the farm already has grid supply.
For remote sites, night-time pump operation or critical water supply, a hybrid or off-grid approach may need to be checked. The best option depends on whether the goal is cost saving, backup reliability, remote operation, or full solar-powered pumping.
This calculator is useful for agricultural users who want to check solar for:
If you already received a quotation for a solar pump, farm solar system or agricultural solar project, you should check whether the system size, cost and expected savings are reasonable for your actual pump usage.
If your farm has multiple electricity loads such as cold rooms, fans, pumps and processing machines, the Agricultural Solar Calculator may be more suitable. If your main focus is only a water pump or irrigation pump, this Solar Water Pump Calculator gives a more direct pump-based estimate.
Solar100 helps farmers and agricultural users understand whether solar is suitable for water pumps before requesting quotations. After using the calculator above, your WhatsApp message will include pump type, location, pump power, daily operating hours, estimated solar size, cost range, savings and backup advice.
This helps Solar100 check:
Use the calculator above and send your result to Solar100 WhatsApp. We can help you do a basic solar pump suitability check before you request installer quotations.
