I've seen a couple recommendations from long ago, but is there a de-facto standard product for this solution? I've got two 100w Renogy panels I'm planning to install in the next week and would rather not drill into the roof to mound the Z-brackets. Is it still recommended to throw some Dicor sealant on top of the contact part of the brackets as well? Thanks.
Very High Bond (VHB) tape from AM Solar. Yes, cover the bracket bottom with Dicor. This ensures that no water gets to the tape and loosens it up. The VHB tape works great, but I still don't trust it 100%. For this reason I would also use a single screw to mount the bracket to the roof. Extra insurance against high winds.
