@Kuniti_shino Very neat! I think I've seen photos of the bus before, nice to see some more though. That's a LOT of solar!

Regarding the chemistry swap on the Insight, someone a lot smarter than me figured out an intermediate board that goes between the car electronics and the battery. Car still thinks it's a NiCad battery, actual lithium battery gets charged correctly by the intermediate board. It's not cheap (more than I paid for the car) but gives a significant performance and fuel economy boost.
