Are Solar Panels a Fire Risk?

Generally, solar panels have smaller units known as photovoltaic cells that are responsible for converting sunlight into electricity — all these cells connected together to make up a solar panel. Photovoltaic cells observe sunlight and produce direct current (DC) and then convert it into usable alternating current (AC) with the help of inverter technology.

Can solar panels catch fire?

Whilst the risk of solar panel systems catching fire is extremely low, like any other technology that produces electricity, they can catch fire.

What causes a solar panel fire?

External influences that can cause solar panel fires include moisture and water ingress into parts of the PV system, such as the DC and AC connectors. Additionally, consideration should be given to things such as build-up of dirt, bird droppings, and foliage on PV panels. These can lead to shading, causing hot spots that can escalate to burning.

Can a solar panel fire damage a building?

Planning and design issues can also add to the risk of solar panel fires, causing damage to not just the PV installation, but the building on which they are mounted. An example of this would be a PV system being installed on a combustible/partially combustible roof, with no fire-resistant covering.

Can a PV system catch fire?

PV system fires are rare but can cause a lot of damage to a building and its contents. While it is rare for panels to catch fire on their own, poor workmanship combined with negligence can cause issues that eventually lead to electrical fires on the roof or at the inverter.

Are solar PV systems causing fires?

Our engineers and inspectors have inspected over 10,000 grid-connected solar PV systems in the past ten years. During this time, we have concluded that there are three main causes of fires: DC isolators, especially the DC isolators located at the roof (rooftop isolators), are a known common cause of fires in PV systems.

How to minimise fire risk from solar PV systems?

The solar industry welcomes clarity on how to minimise fire risk from solar PV systems, which in absolute terms is extremely low. “The core way to mitigate any risk is to ensure the highest possible quality in the design, installation, operation, and maintenance of solar systems.
