It's up to $3,500 to get permits to put solar on. Apparently there are huge import duties on solar panels, at least from China. There's a cost equation. I just hadn't realized that there was maybe a barrier on the building code piece.
How difficult is it to reinforce the buildings that are being built now that aren't up to that standard? Do you have to strip the roof off? Is there a cost? It gets into the question of retrofitting. Can you reinforce a roof and then do solar, or do we need to be building for that in the future?
