Toward a new method for qualification of large solar arrays against ESD and arcing risk

Résumé

The development of large flexible solar arrays represents a challenge for the representativity of electrostatic discharges tests. The propagation of the flashover plasma on longer distances increases the maximum duration of ESD, and hence the risk of solar cells degradation. In this work, a plasma expansion model has been used to compute the flashover propagation on a large solar panel. A new flashover current simulator has been designed from simulation results, and tested on solar cells coupons. The electrical characteristics of the discharges indicate a higher dispersion of primary discharge duration than with FO simulator representative of smaller panels. In presence of secondary arcs, the primary discharge duration tends to increase with the arc current.
