Only reason to have a generator is to run the air conditioner 24/7 and are you really going to do that? If I need air I am looking for hookups.
With conservation you may not need solar or generator for 3 to 7+ days once you adjust to conserving battery power. Then solar just extends the time or power you use.
OK solar will do about nothing in a solid canopy of shade. However even an hour or two of sun can really give the battery a boost. Generator seems like a quick, easy, low cost solution. However you still need more batteries and a good three stage converter to make it work properly. Then there is noise and the smell of exhaust for you and your neighbors.
I would encourage you to go solar.
