If you own an EV, you've already ditched petrol. Now, cut the electricity bill too.
The Math of Solar EV Charging
Driving 2,000km/month in a BYD Atto 3 consumes ~300 kWh.
Cost from Grid (RP4 domestic, 44.43 sen/kWh): about RM 133 (about RM 163 if your home uses more than 1,500 kWh a month)
Cost from Solar: about RM 0.27/kWh (forgone export credit); the system cost (a RM 17,999, 7.44 kWp system) spread over 25 years of generation works out to about RM 0.08/kWh.
Smart Charging
Modern inverters can integrate with EV chargers. They can be set to "Green Mode," charging your car only when there is excess solar power, so more of your driving runs on your own solar energy.
System Sizing Tips
Planning to get an EV? Add 2kW to 3kW of extra solar capacity to your system design now to future-proof your home. See our solar + EV charging solutions for combined system packages designed specifically for EV owners.
