Pretty sure it's 18 for the edges. The 36 was for a path to the ridge so firefighters can reach the top safely, but you can confirm with them.Are you sure it’s 18”? When I googled, it says 3’.

Check your local requirements. For us, it was 36" total at roof peak, so 18" per side. No min distance between panels and they could go as close to the edge as desired except not abutting gutters and with enough access for installation/maintenance (minimal). The exception is the part of the roof deemed the designated access point for firefighters which was labeled on the layout plan, which on my house is the front porch cover, so there the panels are a greater distance from the edge.Are you sure it’s 18”?

Yep mine used drones to map it due to how steep mine is.Check your local requirements. For us, it was 36" total at roof peak, so 18" per side.

Also, as @Darkxerox said, after an aerial view based estimate, an installer walked the actual roof and found there was much more available space between vents and away from edges.
