Configure solarSolar + EV Charger: Power Your Car Free with Sunlight
Malaysia has over 36,000 EVs on the road but only 5,360 public chargers — and grid electricity just rose to 45.40 sen/kWh. Combining solar panels with a home EV charger lets you drive on free sunshine, eliminating your monthly charging bill entirely.

How Much Does EV Charging Cost in Malaysia?
The average EV consumes 15–20 kWh per 100 km. At typical Malaysian driving of 1,500 km/month, that's 225–300 kWh of charging per month — at today's tariff that's real money.
| Charging Method | Monthly kWh | Rate/kWh | Monthly Cost | Annual Cost |
|---|---|---|---|---|
| Grid charging only | 225–300 kWh | RM0.454/kWh | RM102 – RM136 | RM1,224 – RM1,632 |

Why is the rate 45.40 sen/kWh?
TNB's revised electricity tariff (effective Jan 2024) charges domestic consumers 45.40 sen/kWh for usage above 300 kWh/month. EV charging typically pushes homes into this band, making solar-powered charging significantly more valuable than the base rate suggests.
Which Home EV Charger Should You Install?
Three AC charger tiers cover 99% of Malaysian home EV charging needs. All are compatible with Type 2 plugs used by BYD, BMW, Mercedes, and most EVs sold in Malaysia.

3-Phase vs Single-Phase Supply
Most landed homes in Malaysia have single-phase supply, which limits charger speed to 7 kW. If you want 11 kW or 22 kW charging, you need to upgrade to 3-phase supply first (typically RM3,000–RM8,000 via TNB). For most owners, 7 kW overnight is perfectly sufficient — a full charge while you sleep.
RM2,500 Income Tax Relief for Home EV Charger
The Malaysian government offers an income tax relief of up to RM2,500 for home EV charger installation costs. This is available from Year of Assessment 2022 onwards.
Who qualifies
Malaysian tax residents who purchase and install a home EV charger (EVSE — Electric Vehicle Supply Equipment).
What is claimable
Purchase cost + installation cost of the charger unit, up to RM2,500 total relief per individual.
How to claim
Declare under "Purchases of EV Charging Facilities" in your income tax return (e-Filing). Keep your invoice and installation receipt.
Effective savings
At 24% tax bracket, RM2,500 relief = RM600 actual tax saved. At 26% bracket = RM650 saved.

How Much Solar Do You Need for EV Charging?
Adding an EV increases your home's energy consumption significantly. The key is to right-size your solar system to cover both your home usage AND your EV charging. Here's a practical guide.
Assumes: 15–20 kWh/100 km consumption, Malaysia average 4.5 peak sun hours/day
| Monthly Driving | EV kWh Needed | Extra Solar Needed | Recommendation |
|---|---|---|---|
| 500 km/month | 75–100 kWh | +2–3 kWp | Add 2 kWp to existing system |
| 1,000 km/month | 150–200 kWh | +3–4 kWp | Most common Malaysian EV owner |
| 1,500 km/month | 225–300 kWh | +4–5 kWp | High usage or daily commuter |
| 2,000 km/month | 300–400 kWh | +5–7 kWp | Long-distance or 2 EVs |
Rule of Thumb
Add 3–5 kWp to your existing solar system for every EV you own. A typical Malaysian household with one EV driving 1,500 km/month needs at least a 8–10 kWp total system to cover both home usage and full EV charging.
Malaysia Peak Sun Hours
Malaysia averages 4.5–5.5 peak sun hours per day — among the highest in Southeast Asia. This means a 5 kWp system generates approximately 675–825 kWh/month, enough to power a home AND charge an EV for 1,500–2,000 km.
Solar Systems That Cover EV Charging
These Trexon system sizes are specifically recommended for EV owners — sized to handle both home consumption and full EV charging on Malaysian sunlight.
Why Home Charging Matters More Than Ever
Malaysia's EV market is growing fast — but public charging infrastructure is not keeping pace. Home charging with solar is the smart long-term solution.

The Public Charger Gap
With 36,690 new EVs registered in 2025 alone and only 5,360 public chargers nationwide, Malaysia has roughly 6.8 EVs competing for every public charger — and the gap is widening every month.
Public charger queues, reliability issues, and inconsistent pricing make public charging frustrating. More importantly, public charging at DC fast chargers costs 50–80 sen/kWh — far more expensive than even grid home charging.
Solar + EV Charger: The Complete System
A solar-powered home EV charging setup has three main components working together.
Solar Panels Generate Power
Rooftop panels generate DC electricity from sunlight throughout the day. A typical 10 kWp system produces 40–55 kWh on a sunny Malaysian day.
Inverter Converts to AC
The solar inverter converts DC to AC electricity. Your home appliances use what they need in real time. Surplus goes to the grid (NEM) or to your EV charger.
EV Charger Powers Your Car
The home EV charger draws from your solar supply first, then grid if needed. Park and plug in at night — your car is full in the morning, charged on free solar.
NEM 3.0 and EV Charging Strategy
Under Malaysia's Net Energy Metering (NEM 3.0) scheme, excess solar energy is exported to TNB at the displaced cost rate. For EV owners, the smarter strategy is to consume solar directly rather than export it: charge your EV during daytime solar peak hours (10am–3pm) using a smart charger with scheduling, then use grid power overnight if needed. This maximises self-consumption and minimises export — the economics strongly favour direct self-consumption.

Common Questions About Solar EV Charging
Can I add an EV charger to an existing solar system?
Yes — in most cases you can add an EV charger to an existing solar installation. The key question is whether your current system is large enough to handle the extra EV load. Trexon will audit your existing system and recommend whether to add panels or simply wire in a charger.
Do I need a special solar inverter for EV charging?
No — any grid-tied solar inverter works with an EV charger. However, some premium inverters like the Huawei SUN2000 have integrated smart EV charger management that optimises solar self-consumption. A standard inverter + smart EV charger achieves similar results.
Can I charge my EV overnight if my solar panels don't produce at night?
Absolutely. Most EV owners charge overnight on grid power and use solar during the day to offset the cost through NEM credits. With a battery storage system, you can store daytime solar and use it for overnight EV charging — though batteries add RM15,000–RM40,000 to system cost.
Which EV brands are compatible with home AC chargers in Malaysia?
All EVs sold in Malaysia use the Type 2 (Mennekes) AC charging standard: BYD, BMW, Mercedes-EQ, Volvo, Hyundai, Kia, Chery, Geely, MINI, and others. Tesla vehicles in Malaysia also use Type 2 for AC charging.
Is the RM2,500 tax relief available for companies?
The RM2,500 income tax relief is for individuals (personal tax). Companies purchasing EV charging equipment for business premises may claim capital allowance instead. Consult your tax advisor for the applicable treatment.
