Building the Water Supply System for Your Life
Solar Water Pump for Residents
For rural homes needing daily water, Flowatt solar pumps provide steady, low-cost water from boreholes or rivers using only solar power.
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 Select the Best Solar Water Pump?
Calculate Lift & Head
STEP 1 - Requirements
• What is the water source? (Borehole or River)
• Daily water need? (m³/day)
Step 2 — Calculate Total Lift
- Total Lift = H1 + H2 + 10% × L
- H1: Water surface to ground height
- H2: Tank height
- L: Water delivery distance
Step 3 — Pump Head
- Total Lift ≈ 30%–70% of Max Head
Step 4 — Pump Flow
- Max Flow > Daily Water Use
Choosing the Proper Solar Panels
- Choose a solar panel array with a total power about 1.3 times that of the pump.
- Ensure the voltage matches the pump’s operating range for stable performance.
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.
