Without your response, Drew, I would not have know these issues were important, so thank you for noting it...
First, no idea what climate and shading conditions will be, but I completely understand the significance. I would anticipate SEEKING shady areas, but, one never knows when boondocking... Climate objectives are, of course, sunny clear skies, but that's not what will happen, I'm sure, and cloudy days will be in the equation, no doubt.
As for electrical devices, I have a fridge that will function via AC or Propane. Also, have TV, and anticipate SOME usage, but hard to put a finger on that, and recognize that fridge, TV, and especially A/C can be huge draws on power that may not - likely not - be sufficient to run all these for extended periods.
Nevertheless, I'm generally cautious about such use, even in my own home, and am attempting to minimize generator use as much as possible in these circumstances, knowing it likely will be required to some extent.
