Estimates only. Results assume an empty battery at the start of the free window, about 95% charging efficiency, and that the battery is scheduled to charge from the grid during the window. Free windows, caps and plan availability depend on your address and electricity network. Always check the retailer's current terms, rates and eligibility before signing up. EV driving range is a rough estimate at 15 kWh per 100 km. Sapphire Solar can't sign you up to an energy retailer.
