Hugh,
The largest draw on your power is for the refrigeration of both you and your food. These guys [1] 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 [2] 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
