Just out of curiosity, wouldn't it be a no-brainer for the owner of the building to layer the roof with solar panels and fill the garage with chargers? Seems like free money in a country with lots of sunshine.

The usual problems with this approach are 1) the roof is not big enough for solar panels to power multiple chargers and 2) the power is generated when people are not at home (and probably using their car to go to work).

Then the obvious solution is to put solar panels over parking spots at work. Doesn't need to be that much power, 1-2kW is enough if the car sits there all day (for typical distances people commute with cars)

The most common estimate of the average payback period for solar panels is five to fifteen years. Seems more like a sloppy investment not "free money"

Then you'd have to charge during the day and drive during the night.
