In an effort to better understand firefighter rooftop operations, the hazards that may be encountered when working around PV arrays, and the means in which these electrical hazards could be mitigated or substantially reduced, SEIA has commissioned DNV-GL to prepare a white paper.  This work was also supported by NRG, SMA America, SolarCity, and SunPower. The report, titled Rooftop PV Systems and Firefighter Safety, concludes that any revisions to the rapid shutdown provision of the National Electrical Code should “include criteria for reducing the shock hazard while avoiding the prescription of specific product solutions.” The report further recommends that codes and standards committees “employ quantitative analyses to define criteria for reducing the electrical hazards and allow the industry to develop a range of solutions to meet those criteria.”
