I used a similar mantra as Techwriter when attaching 235 W panel but I used aluminum "U" channel because I have a tilting mount, I determined truss interval (I have wood) by measuring back from a vent opening 16" OC. I drilled the aluminum and through the metal roof into the roof truss. I then fastened through a piece of Eternabond tape, (3) #12 metal screws through each "U" channel and into the (3) trusses. The Eternabond tape seals the screw as it is driven and the #12 size insures against any movement.
Good luck with your install.
