A photovoltaic model based method to monitor solar array degradation on-board a microsatellite

The lifespan of a microsatellite depends on the adequate power obtained from its solar array. Hence, it is important to monitor the degradation of the solar array in-orbit as uncertain activities of the Sun would change the space radiation environment. To monitor the degradation, a degradation model...
