The need for high power solar arrays stems from the advent of the NewSpace revolution, where hundreds and thousands of shoebox-sized satellites can be launched relatively cheaply. To achieve their mission, they often need large deployable solar array structures in space to allow for high performance applications which demand power, like communication constellations, nanosats with electric propulsion and many more.

PowerCube addresses this need by delivering a Commercial Off-The-Shelf (COTS), scalable, deployable solar array for nanosatellites, storable in less than a 1U CubeSat unit, and capable of generating 100W at EOL (End of Life). The PowerCube development entails the development towards a flight in space onboard a NASA ELaNa mission PowerSat with CalPoly in 2023.

Key features

  • 1U stored form factor
  • Redundant actuation
  • Compliant with the CubeSat standard (CP-CDS-R14)
  • Compatible with standard CubeSat dispensers
