Solar Deep Well Pump System

How It Works:
Solar Energy: Solar panels convert sunlight into electrical power.
Controller: The solar pump controller regulates the pump's operation, optimizing performance for water pumping.
Deep Well Pump: The submersible pump efficiently draws water from deep underground, delivering it to a reservoir or irrigation system.

Domestic water pump / Home water supply

Off-grid water system. Reliable solar water pump for home water supply, household use, kitchen washing, and off-grid home water systems.

Is this solar water pump suitable for household daily use?

Yes, it provides stable water pressure for daily home water supply when paired with a storage tank.

Livestock water pump/ Cattle watering pump

Can this solar pump supply water for livestock all day?

Yes, it pumps water during sunlight hours and works with tanks for continuous livestock water supply.

Solar Water Pump for Farm Irrigation & Crop Watering

High-efficiency solar water pump for farm irrigation, crop watering, and sprinkler systems in off-grid agricultural areas.

What irrigation systems can this solar water pump support?

This solar irrigation pump works with drip irrigation, sprinkler systems, and field watering for farms.

A 95m max head pump is typically suitable for a static water level of about 45–70m (150–230ft) for reliable flow.
For a 750W 72V solar submersible pump, plan on 2–3 pieces of 550W solar panels, depending on your sunlight conditions and whether you need a solar pump for deep well irrigation to run more consistently.
Yes. A 750W (72V) solar submersible pump can run with a battery when it is connected to the correct 72V solar pump controller and a compatible battery system. This setup is often used when customers want a solar deep well pump with battery backup for more stable water supply.

A 3-inch submersible pump is typically suitable for a well casing with an inside diameter (ID) of at least 3.5 inches (≈90 mm). This clearance makes installation easier, helps prevent the pump from rubbing the casing, and improves cooling and long-term reliability.
FLW-3SPC3.8/95-D72/750) Standard setup: 1-inch (25mm) pipe — best for short runs and normal household/tank filling
For longer distance / better flow: step up to 1.25-inch (32mm) or 1.5-inch (40mm) pipe after the first section to reduce friction loss and keep stronger flow
A 3-inch 72V 750W solar submersible pump can push water hundreds of meters horizontally after lifting, but only if the total dynamic head (vertical lift + friction loss) stays within the performance curve. Using a larger discharge pipe size is the best way to increase horizontal pumping distance and maintain higher flow.
Pipe friction loss (horizontal distance, pipe size, elbows/valves)
- 50m head → ~1.9 m³/h
- 60m head → ~1.5 m³/h
- 70m head → ~0.8 m³/h
- 95m head → 0 m³/h (max head, no flow)
This is why a solar well pump for long distance water transfer must keep friction losses low.
