Solar Panel Mounting
The Shell solar panel I just got has pre-drilled mounting holes. I intend to mount the panel flush (flat) with airspace underneath. What is the best way to mount this panel? Using wellnuts? Sheet metal type screws?
The aluminum is not exactly thick on the roof and, just as important, I don't want to have any leaks. Nor, do I want the panel blowing off at 70 MPH on the road. What have others done to securely mount their panels? Do you try to ensure that you have a couple srews going into the ribs?
I intend to seal the mounts, but would like advice on what to use for the sealant. I assume Vulkem, but which one?
Thanks for the help.
