The Cost of Flood Irrigation on Malaysian Paddy Land
Paddy cultivation in Malaysia's granary states — Kedah, Perlis, Perak Kerian, and Kelantan — depends on continuous flood irrigation from planting to harvest. For large operators managing 50+ relong of bendang, diesel pump costs reach RM5,000–10,000 per month during the main season. That is RM60,000–120,000 per year just in fuel.
High Diesel Consumption
Flood irrigation requires high-volume continuous pumping. A 10HP diesel pump running 8 hours/day burns 20–30 litres of diesel daily — RM70–105 per day in fuel alone.
Labour Dependency
Diesel pumps require an operator to start, monitor, and stop the system. Labour costs, absenteeism, and human error add RM6,000–15,000/year per pump station.
Subsidy Uncertainty
Diesel subsidy rationalisation has already increased input costs for paddy farmers. Any further reduction hits irrigation costs hardest — a solar pump uses no diesel for daytime pumping (maintenance and backup are separate costs).
High-Flow Solar Pumps for Paddy Irrigation
Paddy flood irrigation is the ideal application for solar pumps: high-volume, low-head, and daytime-only operation aligns perfectly with solar generation curves. No batteries required — the system runs when the sun shines, exactly when water is needed.
- High-flow DC surface pumps — 80,000–470,000L/day output range
- 10–15HP systems for large bendang operations (8–16 relong)
- MPPT controller adjusts pump speed to available sunlight
- Float switch cuts pump when field reaches target water level
- Digital timer programs morning flood-up and afternoon drain cycles
- No fuel, no oil changes, no daily operator required
- Compatible with existing concrete channel and pipe infrastructure
- Remote GSM monitoring — check pump status via phone
How It Works
Pump Output at Peak Sun
Based on 5m static head, 3.5h peak sun
Sizing Guide by Paddy Area
1 relong is about 0.71 acre (0.29 ha); the bands below assume roughly 29,000 L/day per relong (about 10 mm/day). Final sizing depends on water source distance, static head, and soil infiltration rate of your specific bendang. *Market estimates — pump brands are not stocked by Trexon; every system is quoted per site.
| Field Size | Pump Size | Solar Array | Daily Output | Market Estimate* |
|---|---|---|---|---|
| 1–1.5 relong | 1–2HP | 1.5–3kWp | 23,000–47,000 L/day | RM8,000–15,000 |
| 2–4 relong | 3–5HP | 4–6kWp | 62,000–117,000 L/day | RM18,000–30,000 |
| 4–8 relong | 5–10HP | 7–12kWp | 117,000–233,000 L/day | RM30,000–55,000 |
| 8–16 relong | 10–15HP | 12–18kWp | 233,000–467,000 L/day | RM55,000–85,000 |
| 17+ relong | Multiple 15HP | 18kWp+ per unit | 500,000+ L/day | Custom quotation |
Fully Automated Paddy Irrigation
Trexon configures each solar pump system with automation components suited to paddy field operations. No manual pump start. No attendance. No overtime for operators.
Solar + MPPT
MPPT controller starts the pump automatically when sufficient sunlight is available, adjusting speed to maximise output throughout the day.
Float Switch
Installed in the paddy field at the target flood depth. Cuts pump power when the field is full, preventing overflow and water waste.
Interval Timer
Programs secondary pumping windows for mid-afternoon top-up. Configurable per season — wet season vs dry season irrigation schedules.
Government Support for Solar Paddy Irrigation
Green Investment Tax Allowance (GITA) provides a 60% tax allowance on qualifying solar irrigation expenditure for agricultural companies, set off against up to 70% of your paddy cooperative or estate company's statutory income.
GITA is subject to MGTC verification. Trexon provides documentation support for GITA applications.
