Power (PWR)

The objective of the power subsystem is to acquire, store, and distribute power to a spacecraft in order to maintain the functionality of that spacecraft throughout the duration of its mission. The Electrical Power System (EPS) must be able to generate power, usually through the usage of solar panels, store that energy, and regulate it so that it is distributed in such a manner that will not harm any of the components of the satellite. Each of the major components of the EPS are determined by the requirements of the rest of the components of the satellite that use power and that availability of power to the satellite on its proposed orbit.
