Chris,
You've probably already considered and rejected this... Unisolar PVL modules on
standing seam roofing. Solves the structure & wind problems. Goes fast if
installed on the pans before they go on the roof. Price is pretty good per watt
now.
Can't beat the look. Made in USA. I think the only downside is you may not have
enough area to place 5kW.
I bet it's getting cold in Montana. You could stick the modules on the pans in a
heated space somewhere. This would really cut down your time and exposure on the
roof.

Dear Wrenches
have a composite (shingle) roof at hand, and the owner wants to upgrade it
to a metal roof and install a 5kw+ array on it. The rafters are those
(sort of) particle board I-beams covered with 1/2" plywood (and shingles).
What's the best metal roofing you could suggest--and would you beef up the
wood to lag into?
Thanks for all your input.
