Abstract
Combiner boxes and disconnect switches in commercial and utility scale photovoltaic systems are locations of DC arc flash hazards. We calculate the DC arc flash hazard at various points of a PV system, and develop a simple factor that relates the power of part of a PV array to the potential arc flash heat exposure. Practical considerations for protecting workers, and opportunities for improved equipment and procedures, are also discussed.
