Power Losses of Solar Arrays under the Action of an Environment in a Geosynchronous Orbit

摘要

We derive calculated and experimental relations characterizing the reduction in the electric power of solar arrays under prolonged (～10 years) action of the environment in orbit. The influence of separate factors related to the environment on the loss of solar arrays power is studied. The following factors are considered: ionizing and ultraviolet emissions, contamination of protective glass by the products of destruction of the outer surface materials of spacecraft, thermal cycling, radiation electrization, and plasma thrusters plumes.
