Z brackets fasten to the bottom of the solar panel, then directly to the roof (or rack). If you use a Z bracket by itself to mount to an RV roof, you would have to undo the screws/glue from the roof if you ever want to remove the panel.
Most RV installs use some type of bracket that can be unfastened from the panel without removing the screws/glue/tape/sealant that fastens the bracket to the roof.
Exactly, Z brackets secure well but IF you later decide to remove a panel, its difficult to remove the underside of panel from the bracket (only 1" of working space to roof), so easier to R&R bracket from roof - though disturbing sealant.
