Solar and electric cars: charging your car from your roof

An electric car can soak up your spare solar. Here's how it works, what a smart charger does and when charging at home makes sense.

Why they pair so well

A car battery is big, so it can soak up solar that would otherwise go to the grid for a small credit. Driving on your own sunshine is usually the cheapest way to run a car.

What a smart charger does

  • Charges faster than a normal power point.
  • Can follow your solar, speeding up when there's spare and slowing down when there isn't.
  • Lets you set times, so it tops up off-peak if the car's home at night.

What if the car's at work all day?

Then weekends and days at home are your solar charging days, and a home battery or an off-peak plan can help the rest of the week.

Our Maximum option includes a smart EV charger, and you can switch it on or off when you look at your system.
