Most people assume 27 sen a unit. Once your EV lands on top of your household usage, the real number is far higher — and it climbs every time you cross a TNB threshold. See yours in under a minute.
TNB doesn't bill your car separately. It bills your house, and where your total monthly usage lands decides the rate on every unit you've used.
That's what makes an EV different from any other appliance you've added. A 1,250 km month needs somewhere around 215 kWh at the wall — enough to push a mid-sized household through one or two thresholds at once:
| Threshold | What happens when you cross it |
|---|---|
| 600 kWh | The RM10 retail charge, AFA and 8% service tax all start applying |
| 1,000 kWh | The Energy Efficiency Incentive rebate disappears completely |
| 1,500 kWh | Your energy rate jumps from 27.03 to 37.03 sen — on every unit, not just the ones above the line |
Cross the 1,500 kWh line and your car isn't just paying for its own units; it's re-pricing your entire household bill. The calculator above shows this as the effective sen/kWh your charging actually costs, which for most homes lands between 50 and 80 sen — and past a ringgit a unit for anyone the car tips over the 1,500 kWh line.
Roughly 1 kWp of rooftop solar covers about 450 km of driving a month. Sized for the car alone, on top of whatever your household already uses:
| Monthly driving | Energy at the wall | Extra solar needed | Roughly |
|---|---|---|---|
| 600 km | ~105 kWh | 1.4 kWp | 2–3 panels |
| 1,250 km | ~220 kWh | 2.8 kWp | 4–5 panels |
| 2,000 km | ~355 kWh | 4.5 kWp | 7–8 panels |
| 3,000 km | ~530 kWh | 6.8 kWp | 11 panels |
Based on 620W panels and 16 kWh/100 km. Most homes add this to a system sized for the house itself, which is why the calculator prices the extra capacity separately rather than quoting a whole new system.
Rent-to-Own from RM0 upfront, or buy outright from RM21,000. Either way, the units your car draws in daylight cost about 19 sen instead of the 50-80 sen TNB charges.
From RM248/month on the 10-year plan, or RM158/month over 5 years with a down payment. Free maintenance and a performance guarantee included.

SuRIA Home is Malaysia's new government solar rebate launched 22 May 2026. It pays RM 600 per kWac of installed solar — up to RM 3,000 cash — directly into your TNB-registered bank account. It stacks on top of Solar ATAP bill savings. Only the first 50,000 households qualify, with a hard deadline of 31 December 2026. Read the full SuRIA Home guide →
Most Malaysian landed-home owners cut their TNB bill by 60–90%, saving roughly RM 250–RM 900 per month depending on system size and consumption. With the SuRIA Home rebate factored in, payback for an outright purchase is typically 3–5 years, with panels warrantied for 25+ years. Calculate your exact monthly savings →
All residential solar must be registered with SEDA under the Solar ATAP programme — we manage the eATAP application and TNB bi-directional meter installation on your behalf. Condominium owners need their management committee's approval for rooftop access first; landed homes don't need additional consent.
