And parking lots.
And parking lots.
1) people cannot drive. The amount of dents or other damage from incompetent drivers done to a concrete-built park house is crazy, I don't want to imagine the damage they'll do to tiny aluminium/steel constructions holding the panels
2) people cannot drive. They underestimate their vehicle height all the time - just google for "can opener bridge". Just a couple days ago a truck driver massively damaged the lighting in a Munich tunnel because he forgot that the excavator on the flatbed was higher than the truck...
There's a simple way to fix that: Have a solid steel bar slightly lower than the max clearance at the entrance. People that can't drive will notice there without causing further damage.
You just build the solar panel mounts like you would usually build lighting mounts (big concrete bases).
Height is less of a concern in some parking lots (where it's virtually all cars)
