What on earth do roof and [structural] building plans have to do with eletrical connectivity to the grid? You're losing the plot and trying to lead us down another sideshow, that is the things i called out as the specific things city dwellers forgot I dont have that they require for the solar permit. 'Society' already decided i don't need those for literally anything else residential but solar.

The most likely explanation is they simply forgot rural folks often don't have roof plans, and should have written an exception in such case that the solar permit could be issued without them.
