It's expensive, solar, but it does work. Yes its not a "generator' but will provide electricity.
It is also quit, and no fumes. So if you don't want to hear a generator running when you are trying to sleep at night, it's nice. Small window a/c in the bedroom and the Fridge with a coulpe lights will get you through.
Another option is charge the batteries with a hydrocarbon powered generator during the day and use the battery/inverter at night.

You know, because I certainly wouldn't know anything about post natural disaster living with no grid electricity.
