I'm learning that difficult and costly part of going off grid is the city rules/regulations/laws. Its much easier to go off grid if your living way out from cizilization but much harder anywhere near jobs, so you end up having to drive many miles and hours to work which kind of cancels out any savings.
I'm at least switching my gear over, all my radios, battery chargers, etc are going 12v powered from a battery charged by solar. Think of it like a UPS you would buy for your computers.
