Example only, based on the NexWafe savings model: 20% BOL efficiency, 75% vs 80% EOL/BOL ratio, 130 vs 70 µm wafers, 100 vs 50 µm coverglass, 90% packing, $3,500/kg launch, 50 kg argon per 10 kW (LEO), $80k reaction-wheel suite with 60% fixed cost. Contact us for mission-specific analysis.
20% BOL efficiency is assumed for both cell technologies, with different EOL retention factors applied. Propellant and reaction-wheel savings are simplified system-level estimates, not directly demonstrated benefits of EpiNex®.
