Until he needs a new roof. Nobody tells you this up front but the cost to remove and re assemble the panels is extremely high and any savings made over those years is out the the window when its time for a new roof. I know a few home owners and my place of work that didn't put their panels back up after needing a new roof because it wound up not being worth it in the end.
