Can photovoltaic systems cause a new fire safety challenge?

They can, however, cause a new intractable challenge, i.e., fire safety. This paper presents a state-of-the-art review of the increasing number of scientific studies on photovoltaic system fire safety.

Can a photovoltaic fire cause a fire?

“Once a photovoltaic fire occurs in a densely populated area of the city, in addition to the high heat radiation generated by factors such as flashover – which may cause harm to firefighters and surrounding residents – the toxic gases generated by the combustion of photovoltaic panels cannot be ignored,” stated the report.

Can burning photovoltaic panels worsen a building's fire behavior?

When a building catches fire, burning photovoltaic panels could worsen an already very hazardous environment. This work deals with the effect of building flame radiation on the fire behaviors of flexible photovoltaic panel installed in building-integrated photovoltaic systems. Cone calorimeter tests were conducted in air with a piloted ignition.

Are PV panels combustible?

Once ignited by an external fire source or a system fault, PV panels burn since they are combustible. PV panels are usually layered and made of silicon as semiconductors and other layers such as PET (polyethylene-vinyl acetate), TPT (tedlar-polyester-tedlar), EVA (ethylene-vinyl acetate) and some cover layers etc.

What happens if a photovoltaic panel catches fire?

Photovoltaic arrays are mounted on the surfaces of modern buildings to harness renewable energy. When a building catches fire, burning photovoltaic panels could worsen an already very hazardous environment.

Can a PV plant cause a fire?

In fact, PV plant installed on a roof or a façade could fail and cause a fire and/or promote or facilitate its spread. Accident analyses have shown that PV systems are often installed without due consideration of fire propagation and fire spread caused by the presence of modules, cables and electrical boards on the roof.
