In that case I suggest installing efficient panels in some large installation somewhere else. Like, a power company solar farm miles from your warehouse.

It's such a strange magpie impulse folks have to want solar on their house. Look at my stuff! I'm doing things!
From a societal point of view the efficient installation is in bulk, serviceable, unobstructed. A rooftop is comically not these things.
