If you plan on extended stay boondocking with a residential, save your time and energey, forget the energy audit. Go with the largest battery bank and solar array the budget will allow.
Then also invest in an AGS (automatic generator start) system and that will cover situations when the solar is not adequate, and believe me there will be those times.
We have been fulltime boondocking for five years now and consider the AGS completes the package. The AGS will maintain the battery bank and supply power to run the ac as needed, hands off.
Extended boondocking/ fulltime boondocking is a whole different ballgame.
