It should be noted that if you are willing to forego selling excess solar power back to the grid you can bypass the need for inspection or approval from your utility. Put some (or all) of your circuits on a transfer switch or generator interlock and connect your solar system to that. Then legally your system is the same as a backup generator install. It should have permitting and inspection requirements similar to those of adding a circuit. That will just a city permit and a city inspection.
