https://www.youtube.com/watch?v=opP13e-TvHM&feature=player_embeddedExcellent info on wind turbines for the home. Many golden tidbits of essential information including wiring efficiency differences between AC and DC, why AC turbines are a better deal
with a rectifier located where your juice does the work or goes into a battery bank,
why odd numbered blade turbines are better , a good discussion of blade materials, angles and designs and also a discussion of turbine towers.
The sun will weaken PVC blades and high speed winds will DESTROY them. Do NOT buy PVC blades.
In fact, ANY plastic is TOAST under daily sunlight after a while. I suppose fiberglass would work but they would be much heavier than metal ones. Heavier blades mean higher wind speeds to get them moving. So, if you are in a low wind area, fiberglass is out too.

I learned a lot from this video. The discussion of the charge controller, inverter and how EXACTLY they are connected was great. Also, the "dump load" feature to keep a wind turbine from wind milling was particularly enlightening.
