Development testing of the advanced photovoltaic solar arrayThe latest design, fabrication and testing details of a prototype wing are discussed. Estimates of array-level performance are presented as a function of power level and solar cell technology for geosynchronous orbit (GEO) missions and solar electric propulsion missions through the Van Allen radiation belts. Design concepts are discussed that would allow the wing to be self-retractable and restowable. To date all testing has verified the feasibility and mechanical/electrical integrity of the baseline design. The beginning-of-life (BOL) specific power estimate for a nominal 10-kW (BOL) array is about 138 W/kg, with corresponding end-of-life (EOL) performance of about 93 W/kg for a 10-year GEO mission.
