24 triangular reflective facets. To assure effective distribution of incident solar flux within the receiver, the facets are contoured and fixed in position. The primary advantages of the offset parabolic, hexagonal panel, and facet design concepts are the resulting low mass moment of inertia of the SD module about Freedom's transverse boom, commonality of parts, and the capability for compact stowage of the concentrator. The compact stowage helps enable the packaging of two complete SD modules in the Shuttle orbiter's payload bay.
