Southeast Queensland's recent severe hailstorms (with hailstones up to 9cm) have triggered over 2,500 insurance claims. While visible damage to roofs and vehicles is obvious, damaged solar panels create a hidden and potentially lethal hazard that most property owners don't recognise.
The Hidden Danger: Delayed Fire Risk
Hail-damaged solar panels can ignite days or even weeks after the storm. When hailstones crack or shatter panel glass, 'hotspots' form that can lead to electrical arcing and fire.
Case Study: Tacca Plastics, Moorebank
After a Sydney hailstorm, a factory's rooftop solar system sustained heavy damage. Power was isolated. Three days later, when hot sunny conditions returned, the damaged panels began arcing and sparked a significant roof fire that threatened the entire facility.
What NOT To Do
- DO NOT go onto your roof to inspect damage yourself - this could be fatal
- DO NOT attempt to tarp or cover damaged panels - this is extremely dangerous
- DO NOT assume the system is safe because it's been 'switched off' - damaged panels continue producing lethal DC electricity whenever exposed to light
Immediate Action Required
- Shut down your system: Follow the shutdown procedure on your inverter or main switchboard. Turn off the PV array DC isolator to secure the cabling.
- Call a licensed electrician immediately if you're uncertain about shutdown procedures or suspect damage.
- Arrange professional inspection before reconnecting the system.
- Check your insurance coverage: Most home insurance policies cover solar panel damage from weather events like hailstorms, but review your Product Disclosure Statement (PDS) to confirm.
