Worse, if power goes out, you can’t use solar to stay electrified because electricity would leak out and potentially electrocute nearby line men.
Has this… really ever been true? We’ve had gas powered generators people can plug into their homes for a rather long time now, and they would be doing the exact same thing as solar installations.
It depends on where you are mainly, but I do believe the kit that prevents what you describe, is functionally mandatory to have for solar. Not certain on that, and it definitely still depends on locale, but I haven’t seen any without that lockout in a loooonging time.
