[RE-wrenches] Seam clamps with or w/o rails

We have done several standing seam roofs with S-5 & had great success.

 

The last roof we attempted S-5 on the roofer said that the panels were
attached solely at the top and only tacked to the roof deck on the lower
portion and that the weight would rip the whole sheet off if we attached to
the standing seams. We resolved the attachment by using L feet. 

It was a real wake up call to realize that there was a system this flimsy
for a metal roof attachment.

Hello Wrenches,

We have a system to install on a roof with standing seams, and are planning
to use S-5 clamps.  The current plan is to use Solarmount rails. This seemed
to be a good solution for grounding, rather than putting lugs on every
module, and also would allow better air circulation under the array.

Would you agree with this concept, or would you recommend connecting the
modules straight to the seam clamps?  Are there any down sides to using the
rails with the S-5s?

Thanks,

Drake
