You're a bit late, Hyundai HEV/EV has solar grid in the panoramic glass roof in Sonata for 2-3yrs now..whole car ain't gonna happen, what do You think that'll cost 1st collision? Can You say doubled insurance?
The Mazda 929 used solar panels to run ventilation fans while parked back in 1991. I was not thinking they would fully charge the batteries but could help extend mileage some .
Good point about costs of repair though .
They say the new EVs have up to 400 range . Not sure how acurate that is but its going in the right direction .
