I have been trying to purchase a small wind generator from Hurricanewindpower.com; either size 500 Watt or size 1000 Watt, grid tie system.
Naturally, I had several questions before I was willing to spend $1000 to $2000.
If you were lucky a person would answer your email. This seemed to be a quite illiterate person with no technical or electrical knowledge.
Answers about cable size requirements, pole sizes of the wind turbine and other technical questions were either not answered at all or the answer seemed to be by a 8 year old child; unqualified and stupid.
