Great post and question, I'm just completing a windmill and solar system just now.

I don't expect it to fully power my home at present from the model I'm building but intial results show a good chance of powering about six 40watt bulbs and other low load appliances. Irons and kettles no chance.

The invertor helps when I switch to solar power, but draw is heavy on the battery pack. Once I get the setup sited permanently I'll hopefully come back at you with a resounding Yes!

yes frasert but you need to replace those bulbs with LED's.
they burn like seemingly forever on your battery pack.
avoid the inverter use it only when seriously needed.

@ frasert
Yes LED's are certainly the way to go. I use the RLBN series from superbrightleds.com with my solar system. I can go for days and not fall below 12v even when it is very cloudy. The part# for the one you will want to get is RLBN-NW30X3SMD. These are excellent for lighting your house and wire directly to 12volts. I completely re-wired my house using 18 ga. double insulated doorbell wire with separate switches.
I built my own simple fixtures using a replacement 4 foot lens from Home Depot and placed 2 of the RLBN LED lights in each fixture.
I first tried to power 2 ballast flourescent lamps and the inverter current draw was 15 amps.
I can turn every light in the house and pull less than 10 amps with the LED lights.
See attached pic.

Even my family don^t wants to heat home with it. We had offered for 3 years to give DRJ200 for evaluation purposes on many forums in Poland. But nobody wanted. Even Pix. They are all barking against only. As this dog mentioned earlier. Please see his last post in topic: DRJ1000.11;-]

Now, use the joule thief circuit with those leds and possibly add some supercaps, and you will have it.  Great light from those leds too by the way.
