If you're curious, it is an envelope house and oriented to make maximum benefit with the Sun. The second floor overhangs the bottom floor which blocks the peak solar energy from hitting the windows.
It produces more energy than it uses, and also uses a couple of turbines. There is a room in the basement that is dedicated to controlling it all and is where the battery banks are all stored.
Caveats:
I didn't do much of the design myself, except the initial drawings and consultation.
I didn't install any of this myself. I'll poke at lots of things, large voltages are not one of those things.
It isn't a matter of being ecologically sound, it is practicality. I lose grid power both frequently and with long durations. I like my modern conveniences. Solar and wind were my options, though I have a whole house generator if/when they aren't adequate.
It isn't ever going to be financially a cheaper option. Never. I'm never going to break even, it will never cost me less than mains power. This is also because I will continue to be on the upgrade cycle, my installer happily lets me trade my old stuff in.
It is, however, much less expensive than homes with similar sizes. The house is on zones and heated according to use. I have no AC as it isn't required. The passive solar and the external temperatures means it never gets very hot here.
I'd be happy to answer questions, but I really don't know much about it. I had it all done for me and barely understand it. There is an in-place monitoring service that tells me what is going on, but I keep that firewalled from the 'net. It lets me see what is doing what, how much energy is stored/produced, what gets pushed out to the grid, etc...
As I said, it's not meant to be green nor will it ever be cost effective. I've only produced more energy than consumed for the past few years. I often have no mains power for a week at a time. Using a generator for that long wasn't really conducive to my lifestyle.
The installation wasn't cheap. I live near Mt. Washington, on the side of a mountain, and wind is a serious issue and I get 3 to 4 meters of snow every year. The best I can offer is pictures. I haven't invested much energy into learning the details and I have absolutely no intentions to try working in it myself.
