Rectangular High Watts per Kilogram (“rHaWK”)
MMA’s innovative solar array architecture for rHaWK addresses the need for high kW/m3 and W/kg and includes long life, high reliability, significantly lower mass and volume, higher mass specific power, and improved efficiency over the state of practice for components and systems. At beginning of life (BOL), the MMA Rectangular High Watts per Kilogram (rHaWK) produces 80+ kW/m3 and 214+ W/kg at 28°C. The same configuration of the array using 29.5% ZTJ cells produces 70 kW/m3 and 204 W/kg BOL. The rHaWK leverages scaled, proven TRL-7/8 solar array technologies that have been in development under multiple prior Air Force and NASA SBIRs. rHaWK’s peak power estimates can scale up to 20kW or even higher with modified configurations.
