Really simple solar:
You want enough panels to re-charge your batteries in one day.
Really simple batteries:
You want enough battery capacity to run for two days.
Lead acid batteries stop being useful at 1/2 their amp hour rating
What you run off of the batteries is very much up to you. Some can't exist without a long list of electronic and electrical gizmos. Others have much more modest needs. Even lighting can be a variable.
At the minimum, you want enough battery to keep the control circuits in the fridge going. You also need enough to power up the propane, CO, and smoke detectors (you want to have those if they are not there now ...). For most of us running the water pump is not optional. Some use of fans is sort of inevitable if you are not using the AC. With a lot of care care you can do that off of an ~ 80AH battery (on a two day basis). Doing it with a pair of those batteries is a bit more common.
Unless you just *have* to have television, I'd ignore the inverter. Everything else is pretty easy to do off of 12V
. You can rig the TV to work on 12V but it gets messy when you add in BluRay players and all the other modern nonsense.
