Beyond cost, what is stopping somebody from going off grid, and relying entirely on their own solar + battery system? Is there some law that makes this illegal? If not, it seems like this would cause a lot of upper income folks to just disconnect from the grid.<p>I've never had such unreliable power as I had when I lived in Mountain View (and I've lived in Buffalo, NY and in the hurricane alley in North Carolina). PG&E is a disaster.
