Ask anyone who has had a system installed. Your system can be totally compliant with national and state electrical code, installed by a competent installer using staff who are licensed electricians, get a stamp of approval from your own's inspectors - and the utility will refuse to connect it and insist you meet an additional set of their own conditions.
And there's nothing you can do about it. No appeals, no review process, nothing.
It's not even consistent, with utilities seeming to just obstruct for the sake of obstructing. Over and over I've of systems going in, the utility comes out (eventually) to inspect, refuses to connect. They're called back out, nothing has changed, and the system gets approved.
This is legislatures getting tired of all that power company bullshit, and bypassing them. As balcony solar rules hit state legislatures, expect some really absurd scare campaigns by power companies, and lots of lobbying.
Power companies see every solar panel they don't own as a threat to the profits they make on their fossil fuel power plants.
