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

[Drake]

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
