For agricultural landowners and farmers in Ferozewala, Badhiana, Muridke, and across Punjab, running irrigation tubewells on diesel generators or grid electricity has become financially unsustainable. Diesel rates exceeding PKR 280+ per liter heavily erode crop profitability.
Converting agricultural water pumps to VFD-driven Solar Tubewell Systems provides free daytime water pumping for crops, eliminating diesel expenses entirely.
1. What is a Solar Tubewell VFD System?
A solar tubewell system uses solar panels connected to a specialized VFD (Variable Frequency Drive) Inverter.
Unlike standard home inverters that convert DC to AC at fixed voltages, a VFD solar inverter dynamically adjusts motor frequency (Hz) and voltage based on available sunlight intensity. This allows 7.5 HP, 10 HP, 15 HP, or 20 HP 3-phase induction water pumps to run smoothly directly from solar panels without needing expensive batteries.
2. Solar Tubewell System Sizing & Cost Breakdown
System sizing depends on water bore depth, pump horsepower (HP), and required water discharge (cusecs).
| Pump Size (HP) | Recommended Solar Panel Capacity | Average System Cost (PKR) | Daily Pumping Hours |
|---|---|---|---|
| 7.5 HP Pump | 10kW – 12kW Solar Panels | PKR 950,000 – 1,200,000 | 7 to 9 Hours |
| 10 HP Pump | 15kW – 16kW Solar Panels | PKR 1,350,000 – 1,600,000 | 7 to 9 Hours |
| 15 HP Pump | 20kW – 22kW Solar Panels | PKR 1,800,000 – 2,200,000 | 7 to 9 Hours |
| 20 HP Pump | 28kW – 30kW Solar Panels | PKR 2,400,000 – 2,800,000 | 7 to 9 Hours |
3. Financial Comparison: Diesel Generator vs Solar Tubewell
Consider a 15 HP tubewell running 6 hours daily during wheat/rice crop irrigation season:
- Diesel Generator Consumption: ~3.5 Liters / Hour = 21 Liters / Day
- Daily Diesel Cost (at PKR 280/L): PKR 5,880 / Day
- Monthly Fuel Expense: PKR 176,400 / Month
- Solar Tubewell Operating Cost: PKR 0 / Month
Payback Period: A 15 HP solar tubewell system pays for itself in less than 2 to 2.5 years through total diesel savings!
4. Ground Mounting & VFD Protection Features
- Heavy Duty Ground Mounting: Elevated galvanized steel ground frames angled for maximum daily solar capture.
- Dust & Weatherproof Enclosure: IP65 rated outdoor metal cabinets housing the VFD drive, DC disconnect switches, lightning arrestors, and phase monitoring relays.
