Roof mount hardware

[doox00]

I am having 20 panels installed on the roof of my pole barn (I have the panels already, hiring someone to do the work), what are some recommended roof mount kits I should look into getting for this, it is a shingle roof. There will be 2 strings of 10 that will be go to one of my inverters (EG4 6000XP), recommendations of the proper wiring I need for this as well (new to solar and new solar install).

Thanks!

I'm using MiniRail express. Was a bit concerned that they're only screwed into the metal but that's their design.
