Charging an EV at home already costs far less than running it on petrol, but pairing that charging with solar takes the running cost even lower, in many cases close to free, if you charge at the right time of day.
Why solar and EVs are a natural pairing
A full home EV charge typically draws somewhere between 20 and 40kWh, depending on the vehicle and battery size, which is a substantial daily load. If that charging happens while your panels are generating, you’re covering it with power you’ve already paid for once, rather than buying it twice.
Sizing solar around EV charging
Households planning to charge an EV regularly generally need a larger system than a typical home, since a 6.6kW system is usually sized around household appliances alone, not an EV on top. A 10kW Solar System gives meaningfully more daytime headroom to cover EV charging without pulling from the grid.
Quick Tip
Scheduling your EV to charge during daylight hours, rather than overnight, is what actually captures the free power benefit. Most home chargers let you set this once and forget it.
Battery or no battery?
If your daily driving means you’re not home to charge during the day, a battery lets you store midday solar and release it into the car charger in the evening instead of losing that benefit entirely.
Plan your solar around your EV
Whether you already own an EV or you’re planning one, sizing your solar system around that future load now avoids a costly upgrade later. We serve EV households across Melbourne’s North and suburbs like Mickleham.
