Functional Requirements

• Harvests energy
• Provides the required amount of power to other subsystems (Comms, Payload, ADCS, CDH, Potentially mech?)
• Provides the required amount of power to EPS systems to retain functionality
  • Must be able to keep the batteries in a safe operating state (temp, overcurrent, over/undervoltage, state of charge)

Non-Functional Requirements

• Must be able to collect and process data to maximize power generation
• Must be able to detect failure conditions and respond appropriately (needs to be expanded on how this actually works)

Constraints

• Minimize cost
• Eeeeeverything needs to be redundant. There should not be any single point of failure because everything dies if we do
• Must be radiation-resistant to twice the max expected condition (margin/SF is totally arbitrary)
• Must be vibration resistant to twice the max expected condition (margin/SF is totally arbitrary)
• Total chemical energy on the craft must not exceed 100 Wh
