Abstract:

This technical report presents the physical configuration, preflight testing, and on-orbit data analysis for the Experimental Solar Array flown on the TacSat-2 satellite (a.k.a. Roadrunner). Successful deployment of the fold integrated thin-film stiffening solar array was demonstrated. In addition, on-orbit electrical performance data was obtained for approximately 79 watts (Beginning-of-Life (BOL), Air Mass 0 (AM0), at 25C) of triple junction a-Si (amorphous silicon) thin-film solar cells integrated in a series/parallel configuration to support a 28V spacecraft bus. Measured on-orbit electrical data showed reasonable agreement with predicted on-orbit operation.
