The adaptation of the Space Telescope solar array to experimental platforms or space shuttle limited duration missions is considered. Using the present design technology, a power growth up to 10 kW is envisaged. Geostationary orbit power versus mass for variants up to 8kW (10 year equinox) are shown. Power can be increased by adding solar panel assemblies (SPA) to the blankets. The present 8 in drum diameter and flexible power transfer harness enables a further SPA to be added by extending the Bi-Stem booms an additional 1.2 m, giving 6 kW beginning of life (BOL). By deletion when not required of shadow diodes (+4%) and the use of higher efficiency cells (+5%) a further power growth to 6.7kW BOL is possible with negligible impact on the present design, and qualification status. For increases of SPA above 6 per half wing, 24 total, the Bi-Stem size must be increased, Alternatively, Bi-Stem type and drum diameter increase may be possible. Both modifications are straightforward but require partial requalification.
