While I agree that the solar output from a car roof isn't there, I'm sure one of the cars I was looking at had or had the option for roof solar panel. I think it was defined as "maintain battery charge while parked. "
I assume this would be to offset the alarm power consumption/ having your 4 wheeled PC on standby.
The Solar panel will be for trickle charging the 12volt battery and not the main high voltage battery. Early leafs had the issue of this running down to the point you couldn't start the car, slightly ironic when it has a massive battery as well!
