We attempted a couple of jobs with the S5! kit and no rails and lining

And if used with rails, helps with lowering module temperature (increasing

further away from the roof deck the modules is, the less likely nesting is

Agreed, standard S-5! with L-foot and rail allows for the easiest install
and most flexibility. We also stagger the clamps as much as possible to hit
as many seams as possible. Also, make sure the pans are installed correctly
as they will be the weakest link.

I agree - the regular S-5! clamps with L-Feet and rails adds a lot of

The S-5 Kit must be adjusted with the jam nuts potentially at every clamp
location to keep the modules from being forced to follow the roof contour.
We have always used L-feet and rails mounted to the standard S-5 clamps
since it creates a flat surface for the pv.

The is always right!
Just carefully align the S-5!s with a mason line and use a plywood template or
some other material template to keep these straight.
We also use a lot of S-5! and have Milwaukee 12v impact drivers to set the
screws. Check the torque with a wrench as well.
Good luck.

I used them one time and went back to rails.
It would have been prudent to build a thin plywood jig to match the PV you are
using.
The advantage of rails is that you have somewhere to attach wires, boxes (and

is specified as "Customer Responsibility" in the
