Queenslanders are no strangers to wild weather, and with Cyclone Alfred making landfall, many homeowners with solar panels are asking the same question: Will my system hold up? Could debris shatter them? And if your solar system is damaged, what’s the best course of action?
Although solar panels in Australia are designed to endure extreme weather, the combination of solar panels and cyclone conditions can bring unpredictable forces that put serious strain on both your roof and solar system. That’s why preparing ahead of time and ensuring your roof is strong and well-maintained are essential steps in protecting both your home and your solar investment.
Are Solar Panels Built to Withstand Cyclones?
Solar panels in Australia are designed to handle extreme weather, but whether they can survive a cyclone depends on more than just their durability. How well they’re installed, the strength of your roof, and regular maintenance all determine whether they’ll hold up when powerful winds hit.
Australian solar panels must meet AS/NZS 1170.2 standards, which means they’re tested to withstand wind speeds of up to 240 km/h—comparable to a Category 4 cyclone. But while they’re made to be durable, their mounting system and roof stability are just as important in keeping them secure during a storm.
Cyclones bring powerful winds that create strong uplift forces, which can pull solar panels loose if they aren’t properly secured. If the panels aren’t properly fastened, they could shift or even detach. Even if the panels stay in place, intense gusts can put stress on solar panel cable, potentially causing electrical faults or loose connections that impact performance.
The Role of Proper Installation and Mounting
Many homeowners also wonder, how long should solar panels last, especially in cyclone-prone regions. With proper installation and maintenance, solar panels can last 25 years or more, but their longevity depends on roof stability, mounting systems, and weather conditions.
If your panels are secured with sturdy brackets and your roof is structurally sound, they’re much more likely to stay in place. However, if your roof is already weak or damaged, it can put your solar system at serious risk. That’s why keeping your roof in top condition with inspections and restoration is just as crucial as investing in a quality solar installation.
Steps to Protect Your Solar Panels Before a Cyclone QLD
With cyclone season in full swing and Cyclone Alfred hitting Queensland, now is the time to ensure your solar system and roof are prepared for the heavy wind and rain ahead.
✧ Turning Off Your Solar System
Knowing how to turn off your solar panels correctly is essential before a cyclone. Start by finding your solar supply main switch in the switchboard. Switch off the AC supply on the inverter, then turn off the DC supply. Make sure your inverter has completely shut down before leaving it.
✧ Checking Cables and Mounting
Check all solar panel cables and brackets for security before moving forward. Secure all loose connections which could separate during high wind conditions.
✧ Clearing Debris and Hazards
Flying debris can cause serious damage, so clear leaves, branches, and other debris from your roof and gutters. Trim back any overhanging trees that could break in strong winds, and secure any outdoor furniture or loose objects that could be picked up and thrown around by the storm.
What to Check After a Cyclone QLD
Once the storm has passed, inspect your roof and solar panels before switching your system back on.
✦ Checking Your Solar Panels
To check your solar panels for damage, you should inspect both cracks and loose panels and frayed cables. The electrical charge present in solar panels makes it dangerous to perform self-repair work. Contact a licensed solar electrician to check any observed damage on your solar panels.
✦ Checking Your Roof
During inspection examine the roof for leaks and evaluate all roofing materials as you inspect structural elements. The storm season in Queensland can worsen, and minor problems that are left unaddressed can lead to bigger problems for your home.
How Roof Restoration Helps
Your solar panels need a strong, stable roof to stay secure. If your roof is aged, leaking, or cyclone-damaged, it can put your entire solar system at risk. That’s why restoring your roof is essential to keeping your solar panels safe and functioning properly. A well-maintained roof ensures your solar panels stay secure, stable, and efficient.
Your home and solar system will suffer from significant structural damage when you have even minor roof problems. Weaknesses in your roof structure caused by cracked tiles or rusted metal sheets or minor leaks will increase its susceptibility to solar panel movement or detachment during severe weather conditions. Getting your roof checked and fixed on time keeps it strong, saves you from expensive repairs, and helps your solar system last longer.
