Hugh,
The largest draw on your power is for the refrigeration of both you and your food. These guys have some interesting solutions that are direct connect DC. They seem to be fine folks, but the solutions are pricey. Danzer makes an interesting refrigerator that runs on 24 volt. I get the idea from numerous articles that you really should not have just one solar system in your house. I have bought components and run my Ham radio off a panel and a couple of deep cycle batteries, but I have a long way to go.
www.wholesalesolar.com has some great products and great prices if your “puzzler” needs something to study. Ready Made Resources, a SurvivalBlog advertiser, has well-priced, quality, turn-key solutions if your “puzzler” is otherwise occupied. – RV
