FAQs 6

Can solar panels be installed on a building roof?

Solar energy brings many positives from a climate change perspective, but installing solar PV panels on building rooftops can introduce new risks to the building and occupants. Fires resulting from electrical faults is the most common cause of loss associated with roof mounted solar PV installations.

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.

Are solar panels dangerous?

From fire damage to leaking roofs, solar panel installations come with their fair share of challenges. To understand the risks in more detail, check out our article on the challenges and risks of solar panels. 2. Is your roof suitable for Solar panels?

Can solar panels be installed on a combustible roof?

In general terms, solar panels should not be installed on combustible roofs unless some form of fire protection can be installed between the panels and the roof e.g. concrete panels or pebble ballast. 3. Location of solar panels

Can PV panels be installed on a new roof?

Where PV panels are to be installed on an existing roof, consideration should be given to the extra weight they will add. If you are planning to install panels on a new roof as part of a new build or reinstatement, it is important to be aware of the different risk implications of different roof types (e.g. flat vs pitched).

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.
