Hello, Rob! Where I live, I have no Hydro, the community doesn't allow wind-generators, and the wife doesn't want to add any solar because she fears it may reduce our homes appeal when we sell to retire.
We hope to purchase affordable retirement property near a resourceful city, but far enough away into the country that we're allowed to have wind/solar/hydro. I'm keen on micro-hydro, because I already want a pond, and also want to grow half my food, so I'll want a site with water flow most of the year.
My wife wants a pre-existing home that is fairly conventional, but I plan on building a garage/shop to fiddle around in. My hobby will be gradually reducing my heating and electricity bill.
If your property has water flow, I would exploit the hydro fairly soon, to see how much you can get from it. Even a small amount is good, and it may determine the final size of the rest of your system.
One of my goals is to quickly get a small Diesel engine (perhaps from a car) to spin a "Zubbly" motor conversion on a trailer. A small amount of adaptation will allow it to run on either Diesel or free waste vegetable oil from restaurants. I can run it once a week to top off a future battery pack, run heavy loads like laundry or welding, and provide back-up power when the grid is down.
Next, I plan to add some wind-gens to keep the battery pack topped off, as much as is possible. (I'd build one now like you, if it were allowed here)
Cheap fertile land with water will probably mean snow in the winter and lots of cloudy days, so I don't anticipate getting solar PV. If I was staying here in sunny Utah, it would be my first choice, though I do plan on using as much solar heat in the shop as I can get.

Gary has a great solar shop plan, that warms an underground water tank, that feeds radiant floor heat to the house. Fairly easy to gradually add in bits and pieces.
Regardless of your home heat source, the German "passive house" standard will significantly reduce the size requirement and fuel consumption of your heating system if you live in a cloudy area. Im a big fan of passive solar heat collection (even in fairly cloudy areas), but the wife wants a fairly normal looking home.
I'm just doing my homework now, and you are far ahead of me! Please keep everyone posted, any info you can provide will be very helpful. -RonR in SoUtah
