Well, if in high wind days the power is cut off, it's cut off for the whole HOA, right?
So why shouldn't they all consider solar panels/wind turbines, I wonder.
Still, the idea of getting enough batteries and simply charge them when you have power, sounds very sensible, from what I understand of your situation.
Pity about wasting all that wind, sure. If you could make the HOA come to their senses, you might look into vertical-axis turbines.
The newer models are quite impressive, quiet, efficient, resilient, unobtrusive...
Just be careful, they sell a lot of Chinese cheap ones that are basically useless.
