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 — solar locks in RM0/L fuel cost permanently.

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 — 100,000–500,000L/day output range
  • 10–15HP systems for large bendang operations (50+ 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

Sizing Guide by Paddy Area

1 relong = approximately 2.8 acres. Final sizing depends on water source distance, static head, and soil infiltration rate of your specific bendang.

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.

Frequently Asked Questions

What size solar pump do I need for a 10-relong paddy field?+
A 10-relong (approximately 28 acres) paddy field typically requires a 5HP solar pump with a 5–7kWp solar array. This delivers the high flow rate needed for flood irrigation — approximately 150,000–200,000 litres per day. For fields using 50+ relong, a 10–15HP system is recommended.
Is MADA subsidy available for solar pumps in paddy irrigation?+
MADA (Muda Agricultural Development Authority) has active grant programmes for modern irrigation technology in the Muda scheme covering Kedah and Perlis. Solar pumps may qualify under their modernisation grants. Additionally, GITA provides a 60% capital allowance for solar irrigation systems. Contact Trexon for documentation support.
Can solar pumps deliver the high flow rates needed for paddy flood irrigation?+
Yes. Paddy irrigation requires high-volume, lower-head pumping — exactly what DC solar surface pumps excel at. A 10HP solar pump can deliver 300,000–500,000 litres per day, sufficient to flood-irrigate 20–40 relong of paddy fields daily during peak sun hours.
How does the automated timer system work for paddy irrigation?+
Trexon installs solar pump systems with programmable interval timers and float switches. The timer activates the pump at sunrise and runs it through the day. A float switch in the paddy field cuts the pump when water reaches the target level, preventing overflow. The system runs fully automatic — no daily attendance needed.
Does the system work during Malaysia's monsoon season?+
During the monsoon (November–February in the east coast, October–December in the northwest), natural rainfall often meets irrigation needs and reduces pump run-time. Solar panels continue generating even under cloud cover, though at reduced output. During monsoon, the primary cost saving comes from not needing flood-up pumping, which is handled by rainwater catchment.
