Flashover discharge on the solar array is an issue of spacecraft charging, because the discharge potentially causes the catastrophic failure of a satellite. The discharge experiment on solar array has been carried out to investigate the propagation area of flash-over discharge. During the flash-over discharge, neutralization current flows on the solar array strings. The charge of neutralization current was calculated to investigate the relationship between the charge and the distance from the cathode spot. The experiment result in the maximum propagation area of flash-over plasma is 3m in simulated geostationary orbit.
