Everyone, Be real careful when reading any companies sales information. Here is the Ventera output chart. Notice that it takes at least 12.5 mph to produce 1 kw of power. Now I am not saying this is not a good system but notice that to get to the rated 10 kw you have to see a sustained 27.5 mph. It is very important, with any system, to look and find these graphs. You have to be real honest with yourself about what kind of wind you actually have at your site. Go to the site I list below and then compare the output graphs to help determine a payback period. Also take into account what program your utility offers for net metering. Here in Michigan, Consumers Energy will only issue you credits for energy produced. So at this point, the best you can do is to have a net of $0.00 spent on electricity at the end of the year. I realize this is still good, but for those with better wind/output it would slow the payback.
