Flashover propagation of plasma on a solar panel is considered from a physics standpoint. Although useful as a first attempt to describe the flashover phenomenon, the previous perimeter theory is shown to have many areas in need of improvement before it can be used as a guide for spacecraft solar array design. A new, more physical picture is developed here. Results from the U.S. Round-Robin Experiments on Plasma Propagation Speed are used to elaborate the physical principles. The new model explains simultaneous current onset, peaks, and cutoffs at all distances; multiple peaks moving at different velocities; and nonthermal directed velocities. Further elaboration is needed before such a model can be used as a reliable guide to flashover pulse peaks, widths, and electrostatic discharge; but, as it stands, the model corrects many of the perimeter theory’s deficiencies.
