The house is ICF. About 60% buried - southern exposure has windows. Heating is taken care of by hot water heated by outdoor coal boiler which we use to heat the 6000 sqft greenhouse in the winter. Triple pane windows. No expense has been spared, also a foam roof.
Its very windy - average wind speed over 20 mph. http://www.usa.com/rank/wyoming-state--average-wind-speed--city-rank.htm
It's not really a money saving project. It's more of an independence project. I guess there is the issue of not really having another thing I WANT to do with my money. I want to have this.
One question you will have to answer is whether you are prepared to pay 10X or more per kWh for your electric power than you would if you were buying it from the grid.

So yeah, the OP needs to "do the math", but whose math? I'd suggest looking at people who have done it recently, using current prices.
Eric, I don't think your doing a real system evaluation. Your still using grid rather than having extra capacity in your battery bank and likely a larger array (I did go back and read)
If you put in replacement costs of the L-16 batteries (about 7 years) and electronics at 10 years (and figure for true off grid if you'll need more battery bank and array) I think you will get bigger numbers.
I'll check out your hotwater link, I had a nice suggestion over on the Midnite forum but it involved using a DC element and my array is too far from my water heater, I haven't decided what I will do this winter, I was given a small 6gall point of use water heater but if I do a point of use I'll likely go with a 10 gallon version (Ace has some nice ones that already have 2" of insulation) and just replace my current unit.

For example, a dryer is a huge load on a battery system.

i tried that venting of my electric dryer indoors through a filter. it works just fine, but i found it adds too much humidity too fast. when several loads are done it started to create mold in some areas so i stopped doing this. line drying is better as it is more gradual and does not consume electricity.

My finding as well, even with one wash. The humidity load was way too much all at once, water running down the windows, everything that's the least bit cool in the house gets damp.

Pretty sure we will not be having a clothes dryer. The wind and dryness of Wyoming are wonderful for line drying. And although it can be a bit harsh in the middle of the winter, I have always found cold wind very "cleansing" for the psyche and soul.

Nothing like going out to dinner and my wife's little black mini-dress smells like wood smoke.

So this is a furnace, can you open the damper before you fire the stove? My wood stove would just draw fine, I'm not in the great white north, but I've had a fire going in my house for as much as 6 weeks at a time, I only open the damper when I'm cleaning out ash, it really helps then!
