The trouble with most urban areas is the city/town/village won’t let you completely disconnect from most major utilities. I bet you could disconnect natural gas, if you have it, but not from the electric utility. So, you’ll always have the service fees included every month even if you offset your KWH usage with solar.
Kind of a scam but I see both sides of the stories arguments.
They will tag your house uninhabitable and never let it happen.
