THE SHORT ANSWER
DOE warns that poorly secured wiring can be damaged during weather events and recommends purpose-built metal clips or ties rather than plastic ties for string wiring. [1]
Map every rooftop run
Show conductor paths, transitions, slack management and entry points on the design. Identify moving, sharp, hot or water-collecting surfaces.
Specify durable support
Use components approved for the conductor, racking and environment according to engineering and manufacturer instructions. Do not treat ordinary plastic ties as a permanent rooftop design.
Inspect before concealment
Include a quality-control step for support spacing, abrasion clearance, connector seating and drip paths before modules make areas difficult to view.
Recheck after disturbance
High winds, pest activity, module replacement and roof work can change support. If safe ground-level evidence shows loose wiring, shut down only as directed and request qualified service.
Before your next conversation
- Document conductor routes.
- Use purpose-built supports.
- Inspect before concealment.
- Recheck after service or storms.
