Flat roof array on ballasted mounts
Panels tilted up on ballasted A frames across a flat roof, with no penetrations through the covering.
Ballasted frames, set out with walking space between the rows.
A flat roof needs the panels tilting to a useful angle, and the mounting system has to hold them there without putting fixings through the waterproofing. Ballasted frames do that by weight rather than by penetration.
The frames are set out to keep the rows from shading each other and to leave enough space to walk between them, because someone will need to get to them again.

DC cabling run clear of standing water and clipped back.
