Charging your electric car from your own roof

An electric car can use 2,000 kWh or more a year. Charging it from your own panels in summer and on a cheap overnight rate in winter can cut the cost of driving to a few pounds a week.

Solar-aware chargers

A solar-aware charger watches what your roof is making and only sends spare power to the car. On a sunny afternoon that can add 40 miles of range without touching the grid.

In winter

Short days mean less spare solar, so we set the charger to use the cheapest overnight hours instead. You plug in and the schedule does the rest.
