I’m about 2 years from being able to charge at home using excess solar (during 9ish months of the year, anyway) almost exclusively. That, plus not needing nearly as many service appointments, is going to save me enough on running costs to cover about 1/2 of the car payment on the electric car I’ll get (based on current prices, solar wattage / sqft, and my own driving habits). Its a very privileged position to be in.
