Thank you for sharing your experience. With the way solar panel prices have dropped during the last decade, wind powered electrical systems only make economical sense when they have wind turbines about 30 foot in diameter or larger (15-25 KW size). If you have a lot of cloudy days and go the solar option, make sure you find a good Maximum Power Point Tracker (MPPT) controller. Some of them will even boost the panel voltage when it drops below the charging voltage.

That thing looks crazy spinning around. Dont stick your arm in there.
