I am in the same area only a few months of the year electric bill is free. But as a solar home person you have to look at it like this. If you did not have solar all your power would be off the grid so charging your car at home would be as well off the grid. Having solar you are off setting a large amount of what you would have used and not getting in to the CO2 area electric is still way cheaper then buying gas. I drive 76 miles RT to work 5 days a week. That at $3.+ per gal will save me about $1,700 a year in savings. So buying this car is not only saving money on gas but on oil changes that would be about $750 in five years as well Then the time spent at the oil change stores. But in 5 years over $8,000 in CASH.
So the car cost 34,000 + 3,000 sales tax + DMV= $38,000
Gas and oil change savings for 10 years.= $16,000
Fed rebate = $7,500
Nissan LEAF total cost out of pocket in 10 years.=$14,500 Priceless and a good bit of silent driving as well. That is as cheap a sub compact car can get. But wait there more $14,500 sub compact would cost you $16,000 in oil and gas in 10 years making it a $30,500 out of pocket expense.
Just a few cents.
