By the end, you’ll know if solar panels increase your lightning risk, what the real dangers are, and how to protect your system.
Do Solar Panels Attract Lightning Strikes?
No. Solar panels do not attract lightning.
Lightning doesn’t target solar panels. It follows the easiest path to the ground, which depends on things like height, shape, and nearby objects, not on whether solar panels are there.
A tall tree, metal fence post, or TV antenna can be just as likely to get struck. Your solar panels are no more likely to attract lightning than anything else on your roof.
Here’s why the answer is no:
- Lightning looks for the tallest or most pointed object in a given area, not the most conductive one.
- Solar panels sit flat against the roof; they don’t stick up above it like an antenna or a mast. Most residential solar systems sit only a few centimetres above the roof surface.
- The metal in your panels and racking is no different to the metal already in your roof structure, gutters, or flashing.
Why Do So Many People Think Solar Panels Attract Lightning?
This myth comes from a simple misunderstanding of electricity.
Because metal conducts electricity and solar panels have metal parts, it might seem logical to think metal on your roof would attract lightning. But lightning isn’t drawn to metal the way a magnet is to iron.
Lightning is attracted to tall objects and the charges in the clouds above. A wooden flagpole can attract lightning just as easily as a metal one if it’s the tallest thing nearby. Shape and position matter more than the material.
Many people think anything electrical is at higher risk from lightning. Since solar panels generate electricity, it’s easy to assume they might interact with lightning differently.
In reality, they don’t. During a storm, the panels just sit on your roof and don’t do anything special.

The Real Risk: Surge Damage from Nearby Lightning Strikes
Here is where the conversation gets more important. While solar panels don’t attract lightning, your solar system is genuinely at risk from what’s called a voltage surge. This is the real threat, and it’s one worth understanding.
When lightning strikes near your home (not necessarily on it), it releases a massive burst of electrical energy. That energy can travel through:
- Power lines connected to your home.
- Any conductive path that runs near the strike point.
That surge of energy can damage the electronics in your solar inverter, battery storage system, and other connected devices.
The inverter is the most at risk because it has sensitive circuits that control the flow of electricity in your system.
Key facts about surge damage:
- A lightning strike doesn’t need to hit your home directly to damage your system.
- Strikes that hit power lines or the ground nearby can still send a surge through your wiring.
- Inverters typically cost between $1,000 and $3,000 to replace.
- Battery storage systems can cost significantly more if damaged.
- A qualified installer will correctly earth your system, thereby reducing the risk of surges.
If you bought your system from a reputable installer, ask whether surge protection was included. If you’re not sure, it’s worth getting it checked.

What to Do if Lightning Strikes Your Solar System
If you think lightning has hit your home or a strike has affected your system, follow these steps:
- Do not touch the solar panels, inverter, or any wiring until the storm has fully passed.
- Check your inverter for error codes or warning lights once it’s safe to do so.
- If the inverter is displaying a fault or has shut down, do not attempt to reset it yourself.
- Contact your solar installer or a licensed electrician to inspect the system.
- Document everything with photos before any work is done.
- Report the incident to your home insurer as soon as possible.
Even if your system seems to work after a storm, it’s still smart to have it checked. Surge damage can slowly wear out parts instead of causing them to break right away.
Does Home Insurance Cover Lightning Damage to Solar Panels?
Most home and contents insurance policies cover lightning damage, but the details matter. Here’s what to check:
- Does your policy cover solar panels as part of the home structure, or are they listed as a separate item?
- Is there a separate excess for storm and lightning claims?
- Does your policy cover the inverter and battery, or just the panels themselves?
- Is your system professionally installed? (Some insurers won’t cover DIY or unlicensed installs)
Contact your insurer and ask if your solar system is covered. If your policy doesn’t cover everything, you can usually add extra coverage. Some solar installers also offer extended warranties or protection plans for surge damage.
Wrapping Up: Struck by the Facts
So, do solar panels attract lightning? No, they don’t.
Lightning is attracted to tall objects and the easiest path to the ground, not to solar panels. The real risk from storms is voltage surges moving through your home’s wiring, which can affect any home on the power grid, with or without solar. The best protection is a properly earthed system with surge protection devices installed by a licensed professional.
PSC Energy installs solar systems across Sydney and regional NSW, including places with frequent severe storms. Every system we install is properly earthed and meets Australian standards. If you want to know more about protecting your system, or if you’re ready to have solar installed the right way, contact PSC Energy for a free quote. It’s what we do.

FAQ: Solar Panels and Lightning
Can lightning damage solar panels directly?
Yes, a direct strike can physically damage panels, but direct strikes on solar panels are rare. The more common issue is surge damage from nearby strikes travelling through wiring.
Do solar panels increase the risk of lightning striking my home?
No. There is no evidence that homes with solar panels are struck by lightning more often than homes without them.
Are solar panels safe to have during a thunderstorm?
Yes. You don’t need to do anything special during a storm. Your system will manage itself. If there’s a fault, the inverter will shut down automatically.
Should I turn off my solar system during a storm?
You don’t need to. Modern inverters are designed to shut down automatically if a fault is detected. If you want peace of mind, you can switch the system off at the isolator, but it’s not necessary.
Will my solar panels work again after a lightning surge?
It depends on the damage. Panels themselves are often unaffected. The inverter is the most likely casualty. A licensed technician will need to assess the system before you restart it.
