Solar panels are appearing on more UK rooftops than ever before. But following several recent fires where solar PV systems have been identified as a potential factor, homeowners are understandably asking a question that doesn't normally come up when they're thinking about solar:

Can solar panels cause a fire?

It's an important question. But it needs a sensible answer rather than a scary headline.

Solar itself isn't something homeowners should be frightened of. A properly designed, professionally installed and maintained solar PV system presents a very low fire risk. The bigger issue is what can happen when electrical equipment is incorrectly installed, components deteriorate or a system is left for years without being checked.

And recent events have put that firmly back into the spotlight.

Why are solar panel fires in the news?

In June 2026, a fire broke out in the roof of Sidegate Primary School in Ipswich.

Following the incident, Suffolk County Council announced that solar PV systems at 80 schools would temporarily be switched off while investigations and inspections were carried out.

The council was careful not to conclude that the solar panels caused the fires. However, solar installations had been identified as a potential factor in three separate school fires, which was enough for the council to take precautionary action.

It's not the only reason the industry is paying more attention to the subject.

Research published by insurer QBE found UK fire services recorded 171 fires involving solar panels during 2024, compared with 107 in 2022 – an increase of almost 60%. Of those recorded in 2024, 97 occurred at residential properties.

That sounds alarming when read on its own.

But there's an important distinction.

Solar panels aren't usually the whole story

When people hear "solar panel fire", the natural assumption is that a panel has simply overheated and burst into flames.

In reality, a solar PV installation is an electrical system made up of far more than the panels you can see on your roof.

There are cables, connectors, isolators, mounting systems, an inverter and, increasingly, battery storage.

QBE's data identified fires originating from areas including inverters, panels and DC cabling, while issues such as loose connections, damaged wiring and faulty installation were highlighted as potential causes.

This is exactly why the quality of the installation matters.

A system can be producing electricity every day for decades. Connections, ventilation, cable routing, component quality and the way equipment has been installed shouldn't be treated as an afterthought.

What can increase the risk of a solar fire?

There isn't one single cause.

Problems can develop because of:

• Loose or poorly fitted electrical connections

• Damaged or incorrectly installed DC cabling

• Faulty connectors or isolators

• Poorly positioned or inadequately ventilated inverters

• Defective components

• Moisture getting into electrical equipment

• Damage caused by weather, animals or other external factors

• Poor installation practices

• Ageing equipment that isn't inspected or maintained

The Building Safety Regulator has also recently examined how rooftop solar panels can affect the behaviour of a fire once one has started.

Its February 2026 research highlighted that the space between panels and a roof can affect heat and flame movement, reinforcing why the design and layout of rooftop solar systems matter as well as the electrical installation itself.

In other words, good solar isn't just about getting panels onto a roof.

It's about engineering the complete system properly.

How can homeowners reduce the risk?

This is where choosing the right solar company becomes important.

1. Don't choose an installer on price alone

Solar has become extremely competitive.

That's great for customers in many ways, but the cheapest quote isn't automatically the best value.

Ask what's actually being installed. Ask who is installing it. Ask what warranties you're receiving and what happens if something goes wrong several years down the line.

Saving a few hundred pounds at installation isn't worth much if corners have been cut on something that's expected to sit on your property for 20 years or more.

2. Use properly certified installers

Your installer should understand electrical regulations, manufacturer requirements and recognised UK solar installation standards.

Solar Style systems are available with MCS certification, alongside HIES registration and EPVS validation on applicable domestic packages.

Certification isn't there just to create paperwork. It helps provide standards around how renewable energy systems should be designed and installed.

3. Give the inverter room to breathe

Your inverter works hard.

Turning DC electricity generated by your panels into AC electricity your home can use generates heat, which is why the equipment needs to be installed in an appropriate location with suitable ventilation.

Stuffing equipment into an unsuitable enclosed space and forgetting about it isn't good practice.

4. Don't ignore warning signs

Solar systems aren't something you should constantly worry about, but you shouldn't completely forget they exist either.

If your inverter repeatedly reports faults, your system unexpectedly stops generating, you notice unusual electrical smells or sounds, or visible cables or equipment appear damaged, don't investigate live electrical equipment yourself.

Get it checked.

5. Look after older solar systems

The Suffolk systems currently being investigated were installed as part of a programme between 2011 and 2016.

That doesn't mean older solar panels are suddenly dangerous.

It does highlight something the UK is going to have to think about more as the solar market matures: thousands of systems installed a decade or more ago are now ageing.

Panels can continue generating for many years, but the wider electrical system shouldn't automatically be assumed to be fault-free forever.

If you've bought a property with solar already installed and don't know who installed it, when it was last checked or exactly what equipment is on your roof, having the system professionally assessed is a sensible step.

What about solar batteries?

Battery storage is becoming one of the biggest developments in residential solar because it allows households to keep more of the electricity they generate instead of immediately sending unused energy back to the grid.

Modern battery systems are designed with multiple layers of protection, but – just like the rest of a solar installation – equipment choice and installation quality matter.

Batteries need to be installed in an appropriate location and according to the manufacturer's requirements.

The answer isn't to avoid battery storage. It's to make sure the battery, inverter and solar array are designed as one complete energy system, rather than treating each piece of equipment separately.

How Solar Style approaches solar differently

At Solar Style, we believe installing solar shouldn't simply mean finding enough roof space and putting panels on it.

We design and deliver complete energy systems across UK homes, businesses and large-scale infrastructure, looking at the property, electricity requirements, solar generation, inverter, battery storage and wider system together.

That's important for performance.

It's also important for longevity and safety.

The solar industry is growing incredibly quickly, and that's a good thing. More households can generate their own electricity, reduce their exposure to rising energy prices and become less dependent on the grid.

But growth can't come at the expense of installation standards.

Solar should be installed properly the first time.

Because when you're putting an electrical generation system on someone's home for the next 20+ years, there really shouldn't be another way.

Already have solar and aren't sure about your system?

Maybe your panels were installed years ago.

Maybe they were already on the house when you bought it.

Or perhaps recent stories about solar fires have simply made you wonder whether everything is working as it should.

Don't panic and don't start disconnecting equipment yourself.

Speak to an experienced solar professional and get the right advice.

And if you're considering a new solar and battery system, Solar Style can help you understand the right solution for your property, how it should be designed and what you should expect from a professional installation.
