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

[August Goers]

And I guess I should mention that the relatively new Unirac SolarMount-I
might be a good fit too. We just got our first set but haven't installed it
yet - my first impression is that it looks quick and simple but won't have
the same flexibility in adjustment compared to the Solarmount L-foot.

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
