I know the roof is solar panels but that isn't related to those meters on the side. I have solar on my house and it is not in any  way connected to the meters. I don't think it has ever been clear if the solar actually has the interior equipment needed to run. Having the panels on the roof though is good. I once saw a picture somewhere of a field of solar panels either on the ten acres or adjacent to them. To utilize that would be nice along with the roof panels. Just thinking out loud. I'm sure they have given thought to the solar.
