Charge your EV from your rooftop solar — matched to installers who set up solar-aware 'excess energy' charging.
If you have rooftop solar, the cheapest kilometres you'll ever drive come from charging your EV on your own excess generation instead of exporting it for a small feed-in tariff. Solar-aware chargers use a current sensor (CT clamp) at your meter to detect surplus solar and ramp charging up and down automatically, so you're topping up the car for close to free on sunny days.
A CT clamp measures your home's net export; the charger only draws power that would otherwise be exported, or blends a set amount of grid power.
Several popular Australian chargers support 'green'/solar-only and blended modes — your installer will recommend one that suits your inverter and supply.
Homes with 6kW+ of solar and daytime charging flexibility (e.g. work-from-home, or a second car parked during the day).

Get matched →Yes. A solar-aware EV charger uses a CT clamp at your meter to charge from surplus solar automatically. It's the cheapest way to charge if you have rooftop panels and some daytime flexibility.
You need a charger that supports solar/excess-energy modes. Sparx matches you with installers who fit and configure these correctly for your inverter.
Often yes — your EV effectively becomes the 'battery', soaking up midday solar you'd otherwise export for a low feed-in tariff.
