Abstract :
At the last IEEE-PVSC, the new stretched lens array (SLA) concept was introduced. Since that conference, the SLA team has made significant advances in the SLA technology, including component-level improvements, array-level optimization, space environment exposure testing, and prototype hardware fabrication and evaluation. This paper will describe the evolved version of the SLA, highlighting the improvements in the lens, solar cell, rigid panel structure, and complete solar array wing. The near-term SLA will provide outstanding wing-level performance: >180 W/kg specific power, >300 W/sq.m. power density, >300 V operational voltage, and excellent durability in the space environment.
