Solar + Battery Burns No Diesel.
Diesel prices in Peninsular Malaysia rose sharply after subsidy targeting in June 2024. Here's your way out.
Why Your Genset Is a Liability
Three compounding costs that make diesel generation increasingly untenable in 2026.
Fuel Costs Are Crushing Margins
At RM5.27/L (Peninsular pump price, 1–7 Oct 2026), a 50kVA genset running 8 hours/day burns about RM15,180 of diesel every month. That's about RM182,000 a year — just in diesel. Not including maintenance, breakdowns, or the driver who refills the tank.
Maintenance Never Stops
Oil changes every 250 hours. Filters, belts, coolant, overhauls. Budget RM500–2,000/month on top of fuel. Diesel engines degrade — performance drops, repairs escalate. Solar panels have no moving parts and last 25+ years.
Noise, Fumes & Compliance Risk
Bursa-listed companies must report sustainability information; check your requirements. Noise regulations exist near residential areas. OSHA fumes exposure rules apply to workers. Every hour your genset runs adds noise and emissions. Solar is near-silent with no on-site exhaust emissions.
Find Your Solar Replacement
From a portable power station for a food truck to a containerised industrial BESS (supplied per project) — most genset loads have a solar-based option, sized per project.

8 Industries Still Burning Diesel
Each of these industries has a solar + battery replacement pathway. Which one are you?
Construction Sites
No grid? Solar and battery systems sized to your load.
Telco Towers
Many off-grid telco towers still run on diesel. Change that.
Night Markets
Many pasar malam stalls still run noisy gensets. Go silent.
Food Trucks
Switch to silent stored power and cut your weekly diesel spend.
Plantations
Palm oil estates spend heavily on diesel for water pumps.
Factories
Replace the genset and, with battery peak shaving, cut maximum-demand charges.
Events & Weddings
Clean, quiet power. No diesel fumes at outdoor events.
Rural Facilities
Schools and clinics deserve reliable power without diesel.
What Your Genset Burns in Diesel
Illustrative: 8 hours a day, 30 days a month, at RM5.27/litre (Peninsular pump price for 1–7 October 2026, set weekly by the Ministry of Finance). Your own litres per month will differ.
| Genset Size | Diesel Used / Month | Monthly Diesel Cost | Yearly Diesel Cost |
|---|---|---|---|
| 5 kVA | ~360 L | RM1,900 | RM22,800 |
| 20 kVA | ~1,440 L | RM7,590 | RM91,100 |
| 50 kVA | ~2,880 L | RM15,180 | RM182,100 |
| 100 kVA | ~6,000 L | RM31,620 | RM379,400 |
| 250 kVA | ~12,000 L | RM63,240 | RM758,900 |
Litres per month use typical burn rates for gensets at moderate load. A solar + battery system price and payback need a site-specific design, so none is shown here. GITA subject to MGTC verification.
60% Tax Allowance — Commission & Submit by 31 December 2026
Claim a tax allowance on your solar investment (60%, Tier 2) and battery storage (100%, Tier 1), set off against up to 70% of your company's statutory income. GITA is administered by MGTC (MyHIJAU); the allowance reduces taxable income, not the system price.

Common Questions
Everything you need to know about replacing your diesel generator with solar.
Peninsular diesel is priced weekly by the Ministry of Finance: RM5.27/litre for 1–7 October 2026, after peaking at RM6.72 in April 2026. At RM5.27, a 50kVA diesel generator running 8 hours/day (about 2,880 litres a month) costs roughly RM15,180/month in fuel alone — about RM182,000/year. A 100kVA genset costs about RM31,600/month. Add RM500–2,000/month for maintenance, oil changes, and filter replacements.
