A solar water pump system converts sunlight into water in real time — the more sun, the more water — and stores the water in a tank rather than in batteries.
Four core components
Solar panels (PV array)
Convert sunlight to DC power. Sized to the pump — Aquasolar lists the recommended array (Wp) for every model. No batteries are needed: the system runs whenever the sun shines and stores water instead of electricity.
MPPT pump controller / inverter
The brain of the system. It maximises energy harvest (MPPT >99%), converts DC to a clean sine wave, soft-starts the motor and protects against dry-run, over/under-voltage, overload and reverse phase. A local LED panel shows voltage, current, power and speed.
Solar pump & motor
A permanent-magnet (PMSM) brushless motor with up to 92% efficiency drives the pump end — screw, impeller or centrifugal depending on the duty. IP68 sealed for submersible use, Class F insulation, stainless or engineered-plastic wet parts by water quality.
Water storage
A simple elevated tank stores the day’s water for use any time — far cheaper and longer-lived than battery storage, and maintenance-free.
DC or AC/DC hybrid?
DC Solar Pump
Runs purely on solar power — the simplest, most economical system. Ideal where daytime pumping is enough: irrigation, livestock, off-grid supply.
- Lowest system cost
- No grid or fuel needed
- 2″–6″, 150–3,000 W
AC/DC Hybrid Solar Pump
Runs on solar and automatically switches to grid or generator (220 V AC) when the sun is weak — for water supply that cannot stop, day or night.
- 24/7 water availability
- Solar-first, grid-backup
- Same efficient PM motor
How to size your pump & panels
1 · Total head
Vertical lift from water level to the outlet, plus pipe friction — measured in metres (m).
2 · Daily flow
Your daily water need ÷ peak sun-hours (≈6) = the flow rate the pump must deliver (m³/h).
3 · Solar array
Size the PV array to ≈1.3–1.5× the pump power (Wp). Every Aquasolar model lists its recommended array.

The advantages
No grid, no fuel
Free solar energy — zero electricity bills and no diesel to buy or haul.
No batteries
Store water in a tank, not costly batteries — lower cost, longer life.
Low maintenance
Brushless motor + full protection means years of reliable, hands-off operation.
Clean & quiet
Zero emissions and near-silent — ideal for farms, homes and remote communities.
Common questions
Does a solar water pump need batteries?
No. A solar pump runs directly off the PV array during daylight and stores water in a tank instead of storing electricity in batteries. This lowers cost and eliminates battery replacement.
What is the difference between a DC and an AC/DC (hybrid) solar pump?
A DC pump runs only on solar power — simplest and lowest cost. An AC/DC hybrid pump runs on solar and can automatically switch to grid or generator power (220 V AC) when sunlight is insufficient, giving 24/7 availability.
How do I size a solar water pump?
Match the pump to your total head (vertical lift + friction, in metres) and required daily flow (divide daily water need by your peak sun-hours, about 6). Then add the recommended PV array. Our free Pump Selector does this in seconds; engineers confirm against the full performance curve.
How deep can a solar submersible pump go?
Aquasolar submersible pumps deliver up to 260 m of head and can be immersed up to 150 m deep, covering most boreholes and deep wells.
How long do solar water pumps last?
With a brushless permanent-magnet motor, no batteries and full electronic protection, a quality solar pump typically runs for many years with minimal maintenance. Aquasolar backs its pumps with a 2-year warranty (3 years on the stainless flagship lines).
