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
What the professional checks
PV/roof/structural professionals check snow load, shedding path, attachments, retention, drainage and occupied areas.
