Owning an EV in Malaysia is already cheaper than petrol, but charging at home can still push you into TNB’s top tariff tier (RM 0.57/kWh). With the new Solar ATAP 2026 policy, exporting excess solar energy to the grid earns you very little (low SMP rates) and credits don’t rollover monthly. So, what’s the smartest move?
Stop selling your solar power. Start driving on it.
🚗 The “Mobile Battery” Strategy
Since Solar ATAP penalizes you for not using your solar energy, your EV is the perfect solution. It’s a giant battery on wheels. Instead of letting your solar energy flow back to the grid for pennies, dump it directly into your car.
The Golden Window: 11:00 AM – 3:00 PM
This is when your solar panels are producing peak power. By scheduling your EV to charge during this window, you are effectively charging for RM 0.00/kWh.
How to Automate “Free” Charging
You don’t need to be home to plug in at noon. Modern EV chargers and smart home apps make this easy:
- Smart Timer: Set your wallbox to start charging at 11:30 AM and stop at 3:30 PM.
- Weekend Charging: If you work at the office, use weekends to “fill up” 100% on sunshine. A single Sunday charge (50kWh) can provide 300km of range for the work week.
- Amperage Adjustment: Lower your charging speed (e.g., to 3kW or 7kW) to match your solar generation curve, ensuring you never pull from the grid.
HOMI Integrated Installation
Installing solar and an EV charger separately can lead to headaches (e.g., tripping your main breaker). HOMI provides a unified solution:
- Load Balancing: We install smart meters that dynamically adjust EV charging speed if your house uses too much power (like turning on 3 air-conds).
- Single App Monitoring: See your solar generation and EV consumption in one dashboard.

By treating your EV as a solar storage unit, you maximize your Solar ATAP self-consumption rate (SelCo), which improves your ROI significantly compared to just selling back to TNB.

Can I charge my EV at night with solar?
Not directly, unless you have a battery storage system (which is expensive). The most cost-effective method under Solar ATAP is to charge during the day (weekends or if the car is home). Night charging pulls from the grid.
Will a 7kW charger overload my house?
It can, if you have many other appliances running. That’s why HOMI installs “Dynamic Load Balancing” chargers that automatically lower the charging speed if your household load gets too high, preventing trips.
How much solar do I need for an EV?
Roughly, driving 2,000km/month requires about 300-400kWh of energy. We typically recommend adding an extra 3kW to 4kW of solar capacity specifically to cover your EV’s needs.
