What is EV Charging (Solar)?
Using solar-generated electricity to charge an electric vehicle, significantly reducing running costs.
Quick Answer
Solar-powered EV charging is increasingly popular in the UK. The OZEV (Office for Zero Emission Vehicles) offers grants towards home EV chargers for qualifying properties. Smart chargers like the Zappi can automatically divert surplus solar power to your car. A 4kWp solar system can provide 3,000–5,000 km of driving per year from solar alone. Combined solar+EV savings can exceed £2,000 per year compared to grid electricity and petrol.

EV Charging (Solar) Explained
Solar EV charging means using electricity from your solar panels to charge an electric vehicle. Smart EV chargers can be configured to charge primarily when solar production is high, maximising self-consumption. Charging an EV with solar electricity costs effectively nothing (once the solar system is paid off), compared to 24–34p/kWh from the grid or £1.40–1.60/litre for petrol. A typical EV needs 15–30 kWh per 100km.
