TL;DR
A standoff is the mounting post that elevates solar racking above the roof surface, anchored through the covering into a rafter and sealed with flashing, creating an air gap of several inches between modules and roofing. The height lets rainwater and debris pass beneath the array, keeps panels cooler for slightly better output, and on tile roofs supports the rail without crushing the tiles.
What it means
A standoff is the mounting post that elevates solar racking above the roof surface, anchored through the covering into a rafter and sealed with flashing, creating an air gap of several inches between modules and roofing. The height lets rainwater and debris pass beneath the array, keeps panels cooler for slightly better output, and on tile roofs supports the rail without crushing the tiles. Each one is a roof penetration, so its flashing detail and lag engagement into solid wood govern whether the installation stays watertight for decades.
