ETFE film covered solar array was developed for arc mitigation in LEO environment. We used ETFE film because its transmittance is excellent at the wavelengths from 300 to 900nm. In LEO, however, the film will encounter serious space environment, such as AO and UV. Electrical power output may decrease due to degradation of transmittance. To study the effects of AO and UV radiation on ETFE film, we used a combined space effect test facility at JAXA. Although the film color turned white after the test, there was no change of film transmittance. Because of AO-induced erosion, texture structure was formed on the film surface, that trapped incident light and made it pass the film after scattering.
