Have you looked around at other places besides Real Goods ? They tend to be more expensive.
I have to reccomend the place we got our system, RV Solar Electrichttp://www.rvsolarelectric.com/kits.htm
Even though they specialize in RV systems it all translates exceptionally well for yurts and other small spaces. The fellow, Noel, who will probably be the one who answers the phone is SOOOOOOOOO helpful. He will spend as much time with you as you need and patiently answer all your questions. He encourages folks to install the pannels themselves ( EASY..we did it on our bus) and will walk you through it. We still call him two years later with questions and he is always so willing to help without ever making us feel rushed.He tries to find ways by saving you money too.
Anyway, we got the JUmbo package that included one 125 watt pannel plus all the cords and hardware needed, including the charge controller. The package was around 750 bucks, then we bought an additional pannel. You can always add pannels later if you need more. As for batteries Noel told us where to get really cheap batteries that last a long time, ask him about it. All told around 2000 for the pannels, then another couple hundred for the batteries.It pays to have a big battery bank so you can store power for rainy days.
We use very little elctric to begin with, but with our system we can run our fridge/small freezer, watch a movie or two a day on the laptop, surf the net and listen to music. We never used electric lights in any of our homes, by choice, so that saves a lot of power. Instead we use high end swedish lanterns and beeswax candles. After living for so many years without any electricity at all we became used to not having lights at night, and now we love it. There is something so beautiful and peaceful about living by firelight, the whole rhythm of the day/night flows smoother and more peacefuly into the next.
I would just call him, tell him what you are doing and ask him what would be the least expensive way to go to get the power you need. Keep in mind though, prices may have gone up a bit since we bought our pannels two years ago.
We do feel the fridge was the one of THE best investments we made. Ours was only like 650 bucks and we bought it from a marine supply store and picked it up ourselves so there was no shipping. It is the small 3.5 - 4 cubic model (dont remember which but it is plenty of space for us).After living for so many years in the tipi and yurt, with no refrigeration, we were thrilled to be able to have one. Honestly, I think not having a fridge was one of the more annoying aspects . We find we eat a lot better now ( more fresh stuff, not as much dried food) and waste less food.The hole in the ground didnt always keep things a good temp and we wasted a lot of good butter, soy milk and other perishables. An ice box was not much better.
If you do decide to go with the energy efficient fridges stay away from Sun Frost and stick to Nova Kool. Sun Frost fridges are twice the cost of nova kool. All the components are the same (Danfrost compressor), the only difference is that Sun Frost adds three inches of insulation around their models. If you glue a few inches of sytyrafoam (if its going to be built in under a counter this wont be visible, otherwise you would need to find a creative way to disguise it) around the sides of the nova kool then it brings the amps/hour down to half of what it normally would be= 2.5 amps per hour, comparable to the way expensive Sun Frost.
Oh and as for the hot tub, we saved a lot of money just buying the woodstove part. Then we bought a new circular stock tank from a farm supply store. It looked really ugly and didnt hold heat in so we got some pallet boards, took them apart, sanded them,lindseed oiled them then wraped them around the tank and held them together with a metal band on the top and the bottom. In between this and the tank we stuffed hay for insulation. It worked great ! It kept heat in the tub, looked like the fancy wood ones they sell on their site and coat under a hundred bucks !
One more thing, for washing our clothes we got this great thing called a James washer,http://www.lehmans.com/jump.jsp?item...ProductID=4084
Its amore money than we bought ours ten years ago,but works GREAT. That above link Leahmans is a great place for other things also.
Wishing you love and Light on your Journey ~ Pixie
