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. -August

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?
