I think you're missing the possibility of: - Installing rooftop solar - Retaining the existing grid connection but not connecting the solar to it (or not connecting it in such a way that power is sent back to the grid). - Running household electrical loads off of the solar when available, falling back to the grid connection when it isn't. You don't necessarily get full utilisation of the solar energy this way, but you can often still save a whole bunch of money compared to not having the solar. Especially if you are willing/able to load shift energy intensive things like washing/drying to times where the sun is shining. You can also potentially gain additional savings by having a smallish battery that gains you some additional utilisation without it necessarily having to cover your entire daily usage.
