To be fair, I am mostly surprised there are not yet EV or hybrid vans, versus PVs on the roof. Seems like stop-and-go, or lots of idling, fleets would benefit signifigantly.

I imagine vans use the battery for more than propulsion, so PVs on the roof might be welcome. Charging from a generator is probably still more cost-effective, except for some niches (e.g. boon-docking). Lots of van-dwellers have PVs on their roof.
