4 FAQs about Solar container outdoor power fire protection level

How far should a PV system be from a fire?

While extinguishing a fire including a possibly damaged PV system (with a maximum voltage up to 1.5 kV on the DC side), the German Standard VDE 0132:2008, Firefighting and assistance in or near electric installations, recommends a minimal safety distance of 1 m if using a water spray jet and 5 m with a full water jet.

Are building related PV systems a fire hazard?

In 2017, a detailed report about fire incidents involving building related PV systems was published by the BRE National Solar Centre. According to this report (BRE 2017a), compared to a total number of about 1 million PV systems installed in the UK, 58 fire incidents involving building related PV systems were reported since 2010.

Are rooftop PV systems safe?

Rumours about burning houses that can't be extinguished or firefighters who do not attack a fire if PV is involved put rooftop PV systems in a light they do not deserve. In fact, PV systems are of a very high safety level concerning preventative fire protection as well as operational safety and security in case of a fire.

Is PV power safe for firefighters in Germany?

According to Fraunhofer ISE, 2019: “In Germany, no firefighter has to date been injured by PV power while putting out a fire”. Despite the safety levels are already very high, regulations are being formulated to add an extra layer of safety.
