Why Consistent Water Is Critical for Musang King

Musang King (D197) commands RM60–80/kg at farm gate — but only when fruit quality is consistent. Irregular irrigation during flowering and fruit set directly impacts flesh quality, sugar content, and the premium grade percentage of your harvest.

Flowering Stage

Water stress during flower induction causes uneven bloom and poor fruit set. Precise irrigation on a 12-hour cycle maximises fruit set per tree.

Fruit Development

From pin-head to harvest (90–100 days), consistent fertigation determines flesh thickness, creamy texture, and bitterness balance that defines Grade A Musang King.

Revenue Impact

A tree yielding 20 fruits at RM70/kg (Grade A) vs 15 fruits at RM40/kg (Grade B) is a 133% revenue difference per tree. Water consistency is the single biggest lever.

How the Solar Fertigation System Works

01

Solar Array

1.5–5kWp of mono-PERC panels mounted on ground frames or existing structures generate DC electricity during daylight hours.

02

MPPT Controller

The Maximum Power Point Tracker converts panel output to variable-frequency drive power for the pump motor, optimising efficiency at all light levels.

03

Solar Pump

A submersible or surface pump (1–5HP) draws water from bore, river, or pond into a header tank or directly into the fertigation lines.

04

Fertiliser Injector

A venturi or dosatron injector mixes liquid fertiliser at a preset ratio into the water stream automatically during each irrigation cycle.

05

Drip Lines

Pressure-compensating drip emitters deliver water and nutrients directly to the root zone of each tree — zero runoff, zero waste.

System Features

  • Fully automated — no daily operator needed
  • Programmable timers for up to 8 irrigation zones
  • Optional GSM alert for pump fault or dry-run
  • Float switch protection prevents dry-run damage
  • Compatible with all liquid fertiliser formulations
  • Expandable — add zones as farm grows
  • Works with existing drip line infrastructure

Installation Time

1–3 days

Sizing Guide by Farm Size

Durian tree density, drip emitter flow rate, and fertigation frequency determine system size. These are indicative — contact us for a precise farm assessment.

Frequently Asked Questions

Does consistent solar irrigation improve Musang King durian quality?+
Yes. Musang King durian is highly sensitive to water stress during flowering and fruit development. Consistent fertigation via solar pumps ensures the tree receives precise water and nutrient delivery on schedule, improving fruit set, flesh quality, and reducing premature drop. Farmers report 15–30% improvement in Grade A fruit percentage with consistent fertigation.
What size solar pump does a 50-tree durian farm need?+
A 50-tree Musang King farm typically requires a 1HP solar pump with a 1.5kWp solar array. This delivers sufficient flow for drip fertigation systems covering the full orchard. As your farm scales to 200+ trees, a 2HP system is recommended.
Can a solar fertigation system run automatically without an operator?+
Yes. Trexon installs solar pump systems with programmable timers and optional fertiliser injectors. The system can run fully automated irrigation and fertigation cycles daily without any manual intervention. SMS/app alerts notify you of any issues.
How much does a solar fertigation system cost for a durian farm?+
A complete solar fertigation system for a 50–200 tree durian farm costs RM8,000–25,000 depending on pump size, number of drip lines, and fertigation tank configuration. The system typically pays for itself within 2 years from diesel savings alone, before accounting for yield improvements.
Is solar fertigation suitable during Malaysia's dry season?+
Solar fertigation is most valuable during the dry season when Musang King trees need supplemental irrigation for fruit set and development. Malaysia receives 4.5–5.5 peak sun hours daily even during drier months, providing reliable pump operation. A small storage tank (5,000–20,000L) can buffer overnight needs.
