Path-Q Solar
What signs indicate that a solar mounting system has shifted after severe wind?
Answer
Warning signs include visibly displaced or tilted panels, changed gaps or alignment, bent rails, loose or missing hardware, lifted flashing, cracked roof materials, new leaks, cable strain, and sudden output changes. Do not climb onto or touch a suspect array after severe wind; arrange a qualified inspection.
Key points
- Compare the array with installation photos or an undamaged neighboring section.
- Inspect from the ground for movement, sagging, exposed fasteners, and damaged roof interfaces.
- Check monitoring for changes by string, inverter, or panel after the event.
- Treat roof leaks, arcing, exposed conductors, or hanging components as urgent hazards.
What it depends on
- Wind severity and direction
- Mounting system, roof type, and attachment method
- Visibility and accessibility of the affected areas
- Whether electrical or roof damage occurred with the movement
Risks and trade-offs
- A system can be structurally compromised without obvious movement from the ground.
- Walking on the roof or attempting to tighten hardware can worsen damage or create electrical and fall hazards.
- Delaying repairs can allow water intrusion or progressive movement.
Information you may need
- Date and severity of the wind event
- Before-and-after photos and monitoring data
- Roof and mounting documentation
- Any leaks, alarms, exposed wiring, or visible debris
Your next step
What to do next
Keep people clear of the area and have a qualified solar and roofing professional inspect the mounting, roof penetrations, and electrical components.
