I see one use case: leaving the car for extended periods of time unplugged, say at an airport parking lot.
Last year I had to leave my car unused for three months, after which both the 12V battery and the hybrid battery were completely discharged.
Had there been a solar panel on the roof this wouldn't be an issue.
Nowadays most of the cost of solar is installation, so I don't think such a panel would be very expensive.
The 860W panel on the Prius Plug-In is a €2000 option, so it's around twice the price of a rooftop installation, but they're using 34% efficient, monocrystalline cells, so most of the expense comes from that.

- Tade0 6y agoMy experience is that most airports use the roof of the parking lot as well, so there's definitely at least one floor's worth of uncovered space. I don't know of any airport that has 100% covered/underground parking spaces.
