My experience is it would eventually crumble your roof structure.

I mounted an Air 403 on a roof scissor-truss roof. Welded up a mount
that transmitted the forces to three trusses, and spread the load even
further with extra wood bracing. All the mounting was internal with
only a stub protruding through the roof. The turbine mast bolted into
the stub. There were two problems - vibration from the turbine drummed
the roof deck and echoed, and the noise was too close to the living
space. I considered putting more work into the mount, but my intention
had been to use three or four turbines, so it became obvious that it
would be simpler and better to use a tower instead, particularly since
a single 1000W turbine was going to produce more energy than four 400W
Airs. The AirX is reported to be considerably quieter, but IMO it's
unlikely that a successful roof mount would be less work than a
light-weight tower.

Here are some links to in dependant testing of the AirX. Keep in mind
that you'll lose some performance at your altitude.

 I put an Air-X on a 12v battery with an open cell and it didn't
deliver any power either.


Stop cut'n pasting your useless pseudo-science crap links. We know it
is the best you can do and you sometimes means well, not often from
the posting counts, but sometimes.

Thanks for the links. Your set up is a lot more involved than I'd be willing
to do. More array is a lot simpler, especially considering that my cabin is
fully constructed. I'd hate to have to go back inside the structure and
re-build.

Wind info here. The truth is that if you can't get your head around
the info then you had best not bother with wind generators.
