If you’ve lived in Queensland long enough, you know how unpredictable the weather can be. One minute it’s a sunny paradise, the next, the sky turns dark, and the wind starts howling. And now, with Cyclone Alfred on the radar, a lot of solar owners are asking the same question—what happens to my solar panels in a cyclone?
The good news? Most quality solar installations are designed to handle strong winds (we’re talking 200km/h+ in some cases). The bad news? Flying debris, falling trees, and extreme conditions can still cause damage.
So, what should you be doing right now to make sure your solar system survives Cyclone Alfred? Let’s go through it.
We have never had a cyclone in Brisbane since Brisbane has had solar panels on businesses or houses here. Things will be interesting, that’s for sure!
1. How Do Solar Panels Hold Up in a Cyclone?
Most modern solar panels and mounting systems in Queensland are engineered to withstand high winds, but the risk isn’t always the wind itself—it’s everything that comes with it.
Here’s a breakdown of what your system can handle and where potential risks lie:
| Factor | Can Solar Panels Withstand It? | What to Watch Out For |
|---|---|---|
| Strong Winds (up to 200 km/h) | ✅ Yes, if properly installed | Loose or poorly secured racking can fail |
| Heavy Rain | ✅ Yes | Risk of water ingress in poorly sealed connections |
| Flying Debris | ⚠️ Maybe | Large debris can crack panels or damage wiring |
| Hail | ✅ Yes (to a certain extent) | Large hailstones can still cause micro-cracks |
| Flooding | ⚠️ Maybe | Inverters and batteries placed low to the ground are at risk |
If your solar system is installed by professionals and meets Australian wind ratings, it should be safe. But flying debris, falling trees, and extreme conditions can still pose a risk.
2. Pre-Cyclone Checklist for Solar Owners
Before the cyclone arrives, take these practical steps:
✅ Secure Your Solar Panels and Roof
- Check for loose bolts or racking and tighten them if needed.
- Trim any overhanging tree branches that could fall on your panels.
- Store any outdoor furniture or loose objects that could become flying debris.
✅ Backup Your Power
- Fully charge your solar battery (if you have one) before the cyclone arrives.
- Have a generator ready if your home relies on solar power.
- Charge phones, power banks, and essential electronics in case of blackouts.
✅ Know Your Shut-Off Procedure
- If winds get severe, you may need to shut down your solar system.
- Locate your main switch and inverter shutdown procedure so you can act quickly if needed.
✅ Insurance & Documentation
- Take clear photos of your solar panels and system before the storm—this will help with insurance claims.
- Check your home insurance policy to confirm your solar panels are covered.
3. What to Do During the Cyclone
Once the storm hits, stay indoors and prioritize safety. Your solar system is designed to work automatically, so there’s no need to go outside and check on it.
🚫 DO NOT attempt to turn off or inspect your system during the storm.
🚫 DO NOT touch any exposed solar wiring or panels that may have been damaged.
🚫 DO NOT use wet or damaged electrical equipment.
If the power goes out, your solar battery may keep running, but it’s best to conserve power as much as possible.
4. Post-Cyclone: How to Check for Solar Damage
Once the cyclone passes, it’s time to assess your system safely.
Step 1: Visual Inspection
- Look for broken panels – any visible cracks or shattered glass means the panel will need replacing.
- Check the racking and mounting – if panels look loose, get them inspected before turning them back on.
- Inspect your inverter – if it’s exposed to water or not displaying properly, don’t turn it back on.
Step 2: Electrical and Wiring Check
- Check for loose cables or exposed wiring.
- If you see any burn marks, exposed copper, or disconnected parts, call a professional before restarting the system.
Step 3: Contact Your Solar Installer
If you notice any damage, don’t risk DIY repairs. Contact your solar provider to arrange an inspection.
(Speaking of damage, if you remember last year’s storm, we covered similar issues in our hail-damaged solar panel replacement guide. Queensland weather sure keeps us on our toes!)
5. Dealing With Insurance & Repairs
If your solar system gets damaged during Cyclone Alfred, here’s what to do:
1️⃣ Take Photos – Before moving anything, document the damage.
2️⃣ Check Your Insurance Policy – Most policies cover solar damage, but check your exclusions.
3️⃣ Call an Expert – Never attempt to repair or reconnect damaged solar panels yourself.
4️⃣ Get a Professional Report – A licensed solar expert can assess the damage and provide reports for insurance claims.
