Abstract

Abstract A replaceable solar array panel for spacecraft is formed of two or more panels one of which being visible or exposed to the sun and other surfaces being shielded from the sun. The exposed and shielded surfaces are arranged to be replaced by moving or rotating a shielded surface into an exposed surface orientation and to eject, move or rotate an exposed panel surface. The activation of the movements required may be automatic or remotely controlled from a ground-based station upon appropriate indications of the need for replacement of damaged or otherwise deteriorated exposed surfaces.
