Electron-beam irradiation experiments concerning the arcing discharges on solar arrays were carried out. It is very important to make this discharge mechanism clear and offer a guideline for designing the solar arrays of high reliability. We used a pair of real GaAs solar cells on a substrate as a sample. The sample was biased to -9 kV and the electron beam of the energy of 10 keV was irradiated to the sample. Under that condition, the voltage from DC battery was applied to the gap between the cells. However, the detrimental arcing did not occur even under several conditions of the cell gap distance and the cell gap voltage below 120 V, although a few hundreds of ESD took place. Therefore, the high voltage use of solar arrays is thought not to cause sustained arcing discharge to destroy the satellite system if the arrays are designed to lower the maximum voltage between cell strings with a reasonable distance.
