Solar arrays: snow, ice and shedding zones

Plan snow/ice shedding from PV glazing to protect doors, walkways, vehicles and lower roof elements.

VERT / GREEN

Identify shedding zones below each array before installation.

JAUNE / YELLOW

PV can accelerate release of snow sheets; strategy depends on snow load, roof and location.

ROUGE / RED

Shedding over an entrance, added devices without load/anchor review or dangerous accumulation: coordinate structure, PV and snow management.

Quick triage
