Hi Sara,
There are some guidelines. The absolute minimum for battery charging is 60 watts per 100 amp-hours of storage. The "reasonable maximum" is 150 watts per 100 amp-hours of storage.
If you full time and boondock and are running a generator for 120 volt power then it is best to maximize the shade free space on the RV and populate it with panels. Costs for a DIY install are under $2 per watt.
I'd further recommend a hybrid inverter--because that will allow the battery bank to supplement shore or generator power. This means a smaller cheaper generator can be used--and that fuel costs for it are reduced.
It may be wise to consider switching to a 24 volt battery bank, and using DC to DC converters to power the 12 volt stuff in the RV.

Thank you. I'll have to sit down with my husband and try and figure out how much we'll need. I wish there was an average that you could start with and you could just add to it.
