==The Basics==
Satellite power modules are widely known as '''electrical power systems, or EPS'''. If you are purchasing Cubesat components as a kit, the EPS will come as a self contained unit, batteries inluded, with outputs for voltage bus distribution. The EPS can be broken down conceptually into four smaller blocks. They are the [[#Power Sources]], the [[#Energy Storage]], the [[#Power Distribution]], and the [[#Power Regulation and Control]] modules.
