摘要：

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.
