Based on the DFH-4 platform developed and the first successful launch of the XX satellite in geosynchronous orbit, the paper uses GaAs solar array output current data of the satellite as a statistical basis. Analyzing the incidence angle of the sun factor, the earth-sun distance factor, solar array drive assembly (SADA) and the temperature of the solar array factors, eliminates the impact of the above factors on the attenuation factor and get its fitting expression, the attenuation factor of 15-years life is Fn=0.9377. ©, 2015, Science Press.
