TL;DR
Solar racking is the structural mounting system of rails, attachments, and clamps that fastens photovoltaic modules to a roof or ground foundation and carries their wind and snow loads into the structure. Roof systems anchor to rafters with flashed lag bolts or deck-bearing mounts, while rail-less designs clamp modules directly to the attachments; all of it must be listed to UL 2703, which also covers grounding through the rack.
What it means
Solar racking is the structural mounting system of rails, attachments, and clamps that fastens photovoltaic modules to a roof or ground foundation and carries their wind and snow loads into the structure. Roof systems anchor to rafters with flashed lag bolts or deck-bearing mounts, while rail-less designs clamp modules directly to the attachments; all of it must be listed to UL 2703, which also covers grounding through the rack. Quality here decides whether the roof leaks years later, which is why attachment count and flashing detail appear on good proposals.
