Florida is great. I lived in Jacksonville for a few years. Some nice rural areas once you get away from the cities and plenty of solar potential. One thing, though, it gets HOT and HUMID in the summer. Heat alone is one thing but the humidity down there is a big deal. Parts of the summer it would rain briefly every day, then for the rest of the afternoon it was sweltering, your sunglasses fogging up and going in the shade doesn't help one bit.
IMO the only way to live there without air conditioning would be an earth home but mind the water table. Air conditioning draws too much power for a solar electric system so keep that in mind too. Also with humidity comes mold and mildew. Not trying to talk you out of it, just a heads up if you haven't lived there so you have some things to think about while you're looking.
Also keep in mind it can get darn cold in Florida in winter, something about that humidity again I think, you just feel it in your bones, at least in Jacksonville where there is a wicked winter wind. If you get a place with
trees for
firewood that would be awesome for heating or you could use it or cooking.
I wish you luck!
