If you've got rooftop solar, charging your EV from your own panels is close to the cheapest driving there is — sunlight into the car instead of paying for petrol or grid power. It's a big reason the suburbs with the most solar are also the ones adopting EVs fastest.
How solar charging works
A solar-aware smart charger watches how much excess power your panels are sending to the grid and diverts it into your car instead. On a sunny day you can charge largely on free solar; when the sun dips, it can top up from off-peak grid power. You set it and forget it.
You usually don't need a special setup — just the right charger
Chargers like the myenergi Zappi and Fronius Wattpilot are built for this. The Zappi works with any inverter brand; the Wattpilot is the natural fit if you already run Fronius solar. Either way, the panels you already have do the heavy lifting — the charger just points the surplus at your car.
Solar plus a smart charger is the combination behind the lowest running costs we see — many households end up charging mostly on their own daytime generation. We set it up to match your system.

Common questions
Can I charge my EV from my solar panels?
Yes — a solar-aware smart charger diverts your panels' excess power into the car, so on a sunny day you can charge largely on free solar and top up from off-peak grid power when needed.
Do I need a special charger to use solar?
You need a solar-aware charger such as the myenergi Zappi (works with any inverter) or Fronius Wattpilot (best with Fronius solar). Your existing panels do the work; the charger points the surplus at your car.
