TL;DR
A solar array layout is the engineered placement drawing showing exactly where each photovoltaic module sits on the roof or ground mount, with rows, orientation, and the fire-code setbacks at ridges and edges that the IRC and IFC require for firefighter access. Designers balance module count against shading, roof obstructions like vents and chimneys, and rafter locations for attachment points.
