Wrenches,
I used S5 clamps with UniRac rails and L-feet. I see that S5 clamps can also be used directly for fastening solar modules to standing-seam roofs. The obvious advantage is lower cost, but are there any disadvantages? If you used S5 clamps without rails, did you have to get a licensed engineer's wind-loading structural analysis? Thank you very much for your advice.
