NOTE:

The Key Figures of Merit from the program referenced in this

SOW,

are the solar array system goals at the conclusion of Option

II

from Section 1.3 of

NRA

NNH15ZOA001N-‐15GCD-‐3

as follows:

• 35%

BOL

cell efficiency measured at

AU

and -‐125 °C (see Note 1)

• 28%

EOL

at the blanket (or equivalent) level, given mission conditions characterized below

• 8-‐10 W/kg2 measured at

EOL

inclusive of the array structure and deployment mechanism, given mission conditions characterized below

• Packaging density of at least kW/m3 (See Note 2), calculated at power level predictions for

BOL

in near earth orbit (1345 W/m2)

• Demonstrate ability to integrate proposed technology into a solar array structure that can be stowed and survive launch conditions.

• Technology capable of operation over the range of V.

• Technology capable of operation in the presence of plasma exhaust fields equivalent to Xe plasma having an energy level (Te) of eV and a number density of 1e8/cm3.

Note 1.

-‐125 °C references the environment and not an intended operational temperature of solar cells on panel or embedded with concentrators.

Note 2.

All gimbals, structures, and control systems required for pointing or otherwise achieving end performance levels must be accounted for in both mass, and stowed volume calculations.

Mission Conditions:

Temperature:
