These are designed to safely tackle. SOLARSTOP® is an ecological and innovative fire extinguishing device designed for applications with photovoltaic installations, which suppresses fire by cooling and lowering the temperature of flammable materials. It is dielectric, so it is safe to fire fighters. Apart from its outstanding fire. That's why the Solar Energy Technologies Office (SETO) funded the Solar Training and Education for Professionals (STEP) program, which provides tools to more than 10,000 firefighters and fire code officials to manage solar equipment as they put out fires.
