[RE-wrenches] SnapNrack

Thu Jun 25 16:11:46 PDT 2015

Hi Jason,

Have you or others been using the new UniRac SM mid and end clamps with the integrated bonding yet? My concern is the “Stainless steel Midclamp points, 2 per module, pierce module frame anodization to bond module to module through clamp.”

We had an MSI Alpha + self-bonding midclamp shatter the glass on an LG 280 last fall, as the factory set point was sticking out too far, so as it was being tightened down, on top of the module the point dug through the module’s top frame hitting the glass, shattering it.

I do wonder if there are any issues with this “point” on the UniRac midclamps potential for doing the same damage?

That decision was based on our distribution network offering better pricing on Unirac, and engineers being comfortable with it. Now with the integrated grounding from Unirac, I can't see moving away from it again barring a significant cost benefit. It also stacks and stocks easier than the Ironridge rails.

Hi Jason,

We've used Unirac for years but have been contemplating Ironridge. I'm curious what your experience was and why you went back to Unirac? 

Anyone else have input on best racking systems for flush-mounted residential systems on comp roof? 

Thanks,

Dana

I'm curious if these vertical integrators will still make their acquired brands available to small dealers through distribution. When SolarCity snatched up Zep, I had concerns about being able to service or add onto existing Zep systems we installed. That's definitely a concern going forward, and reason to perhaps stick with the most compatible racking solutions available. We used IronRidge for a while, which is largely compatible with Unirac, but now we're back on the Unirac bandwagon. 

Interesting times...

We have been using Snap N' Rack for a while, Have lots of installs in Hawaii - so far no problems, I like the convenience of the design for snapping in the slider nut in mid rail, and also the ability to install the panels flush with the end of the rails….

I am curious about the mid clamps on the snapnrack.   The flange that rests on top of the solar panel frame is so small ~ 3/16".    Anyone experience any problems with these failing in a big storm?    With solar panel frames not being square it is nice to have a little extra to grab - I am always curious as to why these clips are made with such a small area to hold the panels down.   

All feedback on these clips is appreciated.

The only complaint with the Snapnrack rails is the thin wall can easily be distorted. This will allow the nut to drop out of its groove. Love the universal end clamps but have learned to assemble every one to check for proper fit before getting on the roof.

Hello Wrenches,

How would you rate the SnapNrack mounting systems against Unirac and other mounting systems?

Thanks,

Drake
