6 FAQs about [The hazards of installing photovoltaic panels on factory buildings]

Can a roof-mounted photovoltaic system cause a fire?

Fires on roof-mounted photovoltaic (PV) systems are rare. When they do happen, however, a combination of electrical hazards, combustible components and limited access can result in significant losses. As the technology becomes more common, this paper discusses how building owners and occupiers should approach and minimise the risks of PV systems.

Are PV systems dangerous?

PV systems include d.c. wiring, with which few electrical installers are familiar. The installation of PV systems presents a unique combination of hazards – due to risk of electric shock, falling and simultaneous manual handling difficulty. All of these hazards are encountered as a matter of course on a building site, but rarely all at once.

What causes a roof mounted solar PV installation to fail?

Fires resulting from electrical faults is the most common cause of loss associated with roof mounted solar PV installations. In some cases, the fire has led to total destruction of the building and all contents. Challenges arise from the varying quality of installation.

Are rooftop PV systems a fire hazard?

Fire safety concerns include electrical ignition sources, combustible loading, and challenges for manual firefighting. Numerous fire incidents have occurred involving industrial and commercial building rooftop PV systems.

Can a PV system fire cause property damage?

The following recommendations are intended to reduce the potential for property damage and business interruption caused by PV system fires. Most items refer to rigid PV modules (BAPV) since there is limited experience to date with BIPV and flexible PV modules. If possible, ground-mounted PV systems are preferred over roof-mounted installations.

Can photovoltaic panels be retrofitted?

Photovoltaic (PV) panels can be retrofitted on buildings after construction or can be used to replace conventional building materials used for roofs, walls or facades. Fire safety concerns include electrical ignition sources, combustible loading, and challenges for manual firefighting.
