As the increasing quantity of space debris has become a great hazard to the high-voltage solar array of the spacecraft in orbit, there is a more urgent need to evaluate the discharge effect of hypervelocity on the solar array as a result of the impact by space debris. In this paper, using projectiles loaded by a two-stage light gas gun, and employing the Langmuir triple probe and the probes of the current and the voltage, we explored the discharge effect on the space solar array at different impact velocities. Results showed that the impact may give rise to solar array discharge, which is induced by high density plasma generated by the impact, and that the increasing impact velocities can lead to more serious damage to the solar array.
