Solar Irradiance & Battery Depth-of-Discharge

A standard 1U CubeSat measures 10x10x10 cm and weighs ~1.33 kg. In Low Earth Orbit (LEO, ~500 km), solar irradiance is ~1361 W/m². Photovoltaic panels with 30% efficiency generate electricity during the sunlit portion of the orbit. If transmitter loads drain the lithium-ion battery past 20-30% Depth of Discharge (DoD), cycle life degrades catastrophically.
