AbstractAt the laboratory, the space environment proof test to evaluate the performance of the solar array against arcing is being performed. Since most test facilities are not large enough to accommodate a full solar panel, laboratories usually use coupons. Usually, the capacitance of coverglass is simulated by connecting a capacitor in the external circuit. But, there are big differences among research organizations about how much capacitance is appropriate. The international standard about the ground test conditions does not exist. The purpose of this research is to investigate the influence of coverglass on arcing phenomena on GEO satellite solar array. The experiment is performed by using a large solar array coupon (400 x 400 mm). The coupon has 50 Si cells. Extent of neutralization differs for each arc. Less charge is neutralized as the distance from arc spot increases. At the worst case, 53 percent charge was neutralized at 325 mm. Plasma propagation velocity is of the order of 10(exp 4) m/s but differ widely for each arc.
