Solar-X Solar Array
Astradyne
The Solar-X is Astradyne’s entry-level high-performance solar array for small GEO and MEO satellites. Featuring triple-junction GaAs solar cells on a rigid composite substrate, Solar-X delivers high power density with minimal mass penalty. The array deploys via a one-shot pyrotechnic hinge and is compatible with standard ESPA-class and EELV secondary payload interfaces.
