Let’s say that your Florida house has solar installed. Your system is so good that you have enough power to be completely off the grid. You don’t need outside power, so your house only uses about $5 of electricity each month. Too bad for you, because Florida utility companies have recently instituted minimum billing. Even if you don’t use their product, you have to pay them for it.
You can’t even disconnect from them, because Florida law requires all homes to be connected to the electric grid.
This is one of those times where Florida law is a bit too draconian for my taste.
