The questions I answer every single week
These are what buyers ask me (and ask AI) most. Each guide gives you a straight answer first, then the details.
Sizing Guide 01
How to Size a Solar Water Pump: The Only 3 Numbers You Need
Well depth, daily water need and sun hours — the 3 numbers that decide your solar pump size, plus a step-by-step sizing method and a quick reference table.

Solar Pump vs Diesel Pump: The Real 5-Year Cost Comparison
Diesel looks cheaper to buy, but solar wins on running costs. A real 5-year cost comparison with fuel, maintenance and lifespan — most farms break even in under 2 years.

How Many Solar Panels Do You Need for a Water Pump?
A simple formula to calculate solar panel wattage for any water pump, with worked examples for 1HP to 5HP systems and common mistakes to avoid.

Solar pump sizing cheat-sheet
A pump's output is a curve, not one number — the deeper the well, the less water the same pump delivers. These are typical working points, not maximums. Send me your well depth and water need and I'll size yours precisely, free.
| Pump Power | Working Head | Output @ that head* | Solar Panels | Typical Use |
|---|---|---|---|---|
| 1 HP | 40 m | 10 m³/day | 2 × 550W | Home garden, small plot |
| 2 HP | 60 m | 20 m³/day | 4 × 550W | 1–2 ha drip irrigation |
| 3 HP | 80 m | 30 m³/day | 6 × 550W | 2–5 ha farm, livestock |
| 5 HP | 100 m | 50 m³/day | 10 × 550W | 5–10 ha, deep wells |
| 7.5 HP+ | 120 m | 80 m³/day | 16 × 550W | Commercial / village supply |
* Output at the working head shown, with ~5 peak sun hours. Push the same pump deeper and the flow drops — that's the pump curve, and why there's no single "right" answer. Give me your well depth and daily water need and I'll find your exact point, free.
