Photovoltaics and fire | Fire Protection Association

Whether responding to a solar panel fire, a fire at a structure featuring solar panels, attending to storm damage, or encountering a property that has a faulty or substandard solar system installed, solar panels pose a serious risk to safety due to their capacity to produce potentially lethal amounts of DC electricity as long as the solar PV system is exposed to light.
