Charging your EV from rooftop solar is about the cheapest way to fuel a car. See what charging from your own panels saves each year — versus the grid and versus fuel.
Adjust to match your setup.
Estimate only. "Fuel cost" values solar charging at the feed-in credit you give up. Real savings depend on when you charge, your tariff and how much solar you can divert to the car.
Transparent maths you can trust — every figure is yours to change.
We split your charging between solar and the grid by the percentage you set. Solar is valued at the export credit you give up by using it yourself; grid energy at your standard rate. The saving versus all-grid charging is what solar buys you; payback divides setup cost by that yearly saving. CO₂ counts only the grid share. Defaults reflect Canadian figures. Estimates only, not financial advice.
Solar charging makes most sense in sunnier, higher-tariff provinces.
Where power is already cheap (Québec, BC, Manitoba) the grid saving from solar is smaller; where it's pricier, solar charging pays off faster. Net-metering rules vary by province — many credit exports at the retail rate, which changes the maths — and output is seasonal, weakest in the short days of winter. Set your solar share, rates and setup cost above to see what it saves.
