PV's on tower [RE-wrenches]

[Jeff Clearwater, Village Power Design]

Hi Kelly,

Did you follow the thread that Ian started on this same subject last 
year?  A number of us chimed in with some serioius concerns about 
mounting PVs on a wind tower.

I just wanted to make sure you hadn't missed that discussion.  You 
could check the archives (11/15-11/16 - "Tubular Towers & PV 
Mounting").

Keep us up to date with how that project goes!  Sounds like a fun one!

Best,

Jeff C.
