About
The Pumpkin 220W Deployable Clamshell Solar Array (DCSA) provides 220W peak output power from 192 high-efficiency triple-junction solar cells (32.2% BoL efficiency) arranged across 24 panels in a clamshell-deploy configuration. Total assembly mass is approximately 5,050g, giving a specific power of 44 W/kg.
Stowed dimensions are 43.9×13.6×11.6cm, fitting within a 7U footprint. Electrical configurations include 8S12P+8S12P (two 20V@5.5A strings), 16S12P (40V@5.5A), or 8S24P (20V@11A) to match a wide range of bus voltages and MPPT requirements. The DCSA is compatible with the Pumpkin EPSM1 module and SUPERNOVA bus family.
