How Solar Water Pumps Work
- Solar panels power the pump to circulate water without grid electricity.
- The hybrid AC/DC design ensures steady operation in all weather, with flexible panel installation on rooftops or open yards.
How to choose water pump?
STEP 1 - Requirements
• What is the water source? (Borehole or River)
• Daily water need? (m³/day)
Step 2 — Calculate Total Lift
- Total Lift = H + 10% × L
- H: Tank height
- L: Water delivery distance - from pump to tank/farmland
Step 3 — Pump Head
- Total Lift ≈ 30%–70% of Max Head
Step 4 — Pump Flow
- Max Flow > Daily Water Use

Solar Water Pump Case – irrigation
In Tanzania, John replaced his costly diesel pump with the Flowatt 72V 900W Solar Deep Well Pump.
It now delivers steady water up to 140 meters, ensuring reliable irrigation and livestock watering even in remote areas.
