"I also has a Prius that can do 12 volts for a LONG LONG time."

Mrs.Hikermor drives a Prius, very capably I might add. That vehicle will be with us, either staying or leaving, in a disaster. I am sure I can get 12 volts from it for a long time, what what about 120 AC? Any simple solutions for the electronically challenged?

For starters, what kind of solar array would keep the Prius main battery charged and how might one hook it up?
