Severe storms across Queensland have made Solar Panels Hail Damage a growing concern for homeowners. With hailstones in some regions exceeding standard testing sizes, many solar system owners are asking the same question: Can solar panels survive extreme hail?
Modern solar panels are built for durability, but understanding how they are tested, what level of impact they can handle, and how to respond after a storm is critical. Proper inspection and preventative planning can save thousands in unexpected repair costs.
At SolarThoughts®, we design and install systems built specifically for Queensland weather conditions, ensuring durability without compromising performance.
Can Hail Really Damage Solar Panels?
Solar panels are engineered to withstand environmental stress, including hail impact. International testing standards require photovoltaic modules to survive impact from 25mm ice balls fired at high velocity across multiple surface points.
Most premium solar panels can handle hailstones up to approximately 35mm in diameter without damage. However, larger hailstones, especially those exceeding 45mm, can crack the tempered glass surface or create internal cell fractures.
In Queensland, hail activity tends to peak during spring and summer storm seasons. While most hail events remain within safe impact levels, extreme storms can exceed standard panel testing conditions.
If you are considering a new system installation, our solar panel installation services ensure your system uses quality panels rated for local environmental exposure.
How Solar Panels Are Built to Resist Hail
The primary protection against hail impact comes from tempered glass. Solar panels typically use 3 to 4mm thick tempered glass that undergoes a heating and rapid cooling process. This treatment strengthens the outer layer, making it significantly more impact-resistant than standard glass.
Tempered glass is designed to:
• Absorb and distribute impact force
• Resist cracking under moderate hail impact
Additionally, modern panels include reinforced frames and encapsulation layers that help absorb shock and reduce structural stress during storms.
However, even when visible cracks are not obvious, internal microcracks can develop within solar cells after a severe impact. These microfractures may reduce performance gradually over time.
Signs of Solar Panels Hail Damage After a Storm
After a hailstorm, it is essential to assess your system carefully while prioritising safety.
Never climb onto your roof to inspect panels. Damaged systems may carry electrical risks.
Start by checking your inverter display during daylight hours. A fault code, warning light, or zero generation reading during sunny conditions may indicate underlying damage.
From ground level, use binoculars to inspect the system for:
- Cracks, chips, or shattered glass
- Moisture buildup beneath panel surfaces
- Discolouration or visible impact marks
- Loose mounting hardware
Monitoring your system output over the following days is equally important. A sudden and sustained drop in daily generation may signal internal cell damage that is not visible externally.
If your home has experienced hail in Brisbane, SolarThoughts® can perform a professional inspection to confirm your system is operating safely and efficiently.
