Building Your Irrigation Water Supply System
Water Supply for Irrigation
Flowatt solar pumps provide steady irrigation for crops, orchards, and greenhouses.
No grid power or fuel needed — just clean, reliable solar energy.
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.

Example of Surface Pump Irrigate: 10-Hectare (24.7-Acre) Farm
Farm Water Needs (10 ha / 24.7 acres)
- Water source: River
- Crops: Field crops / vegetables
- Irrigation depth: 5 mm/day
- Daily water demand: 10 ha × 0.005 m = 500 m³/day
- Lift: ~20 m total lift from water source to field
- Pumping hours: 8 hours/day (daytime)
Flowatt Pump Solution
- FLW-CPM70/20-D300/2200 (3 HP surface pump) × 3 set
- Flow @ 20 m head: ≈ 20 m³/h
- 1 Pump capacity: 20 m³/h × 8 h = 160 m³/day
- Partition irrigation (150–200 m³/day/zone)
Zone A*1 pump
Zone B*1 pump
Zone C*1 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 = 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.
