Indicative 2026 starting points — every figure is editable in the calculator, and results depend on your own bill, roof and installer quotes.
A typical 5 kW system in Malaysia
At around RM 11 per watt, a 5 kW rooftop system costs roughly RM 55,000 and produces about 6,406 kWh in its first year at Malaysia's 4.5 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
- Your setup. Malaysia and Malaysian ringgit are pre-selected, with local electricity rate, install cost and sun hours filled in. Enter your monthly bill, or size the system from your appliances.
- Your roof. Search your address or tap “use my location”, then draw your roof on the satellite map — or just type its area. We check the system fits and read local sun hours from NASA data.
- Your results. Instantly see your payback period, net savings, ROI, system size, year-1 production and lifetime CO₂ offset — compare cash vs. a loan, and download a PDF report.
Common questions — solar in Malaysia
How many solar panels do I need in Malaysia?
It depends on your electricity use, roof space and local sun hours (about 4.5 peak sun hours/day here). A 5 kW system of high-wattage panels is a common starting point for a home — enter your bill or appliances and the calculator gives your exact panel count and system size.
Does Malaysia have net metering?
Yes. Under NEM (Net Energy Metering) you offset consumption on a one-to-one basis for exported energy within the scheme's quota and rules.
Are there solar subsidies or incentives in Malaysia?
There is no broad cash subsidy, but NEM's favourable offset plus tiered tariffs drive the returns; higher-usage homes benefit most.
How much does a solar system cost in Malaysia?
A typical 5 kW system is around RM 55,000 at about RM 11 per watt installed. The calculator prices your exact size.
