Intelsat IV-A solar array performance is assessed. The general characteristics of the Intelsat IV-A spacecraft electrical power subsystem are summarized and the results of initial solar array predictions are presented. Comparison of the actual in-orbit performance of the Intelsat IV-A F-6 solar array with predictions revealed a discrepancy in the short-circuit current, which is probably due to UV radiation degredation. The solar array model was corrected to account for this difference, and susequent in-orbit data suggest that the correction implemented for F-6 is valid for the other Intelsat IV-A spacecraft.
