photovoltaic power systems are a lot less costly than they used to be - if you're fully off grid and won't be connecting to it, having absolute fidelity to electrical code might not be a high priority. If you have some technical ability and can follow documentation and instructions, big 360W panels are like $0.45/watt now, and the setup process for a charge controller and battery bank isn't excessively difficult.
