HI all
my last posts have not shown, heres hoping.
I have seen two of these installed on roofs. I have and one of my students now a solar installer,(NABCEP) has been called to repair. he moved the turbine and placed the turbine on a bergey tower, and it appears to perform like a XL0.1 (1kW) it has been up for about 1 month.
I was called to repair a different unit for no output, in fact negative output (but very little) . I visited the site on a windy day and it was not putting out any significant energy, it was looking for the wind, it would turn left then right, speed up and slow down, like a crazy machine, never holding steady. there were occasions of energy output but it would drop to - about -0.2 amps which I figure is normal wind conditioning unit power draw. The system uses Outback inverter to change the 48 volt DC power to AC grid. I am confident the outbacks were performing up to expectation, the turbine was not.

Check this out: this company claims to have patented a mounting
system which will allow their 1.4kw machine (or multiples thereof) to be
mounted on a roof ridge. I cannot find a power curve of their product on their
website, amongst other things. Opinions, experiences please, thanks. www.windenergy7.com .
