Abstract

Electric power for the Space Station Freedom will be provided by four photovoltaic (PV) power modules using silicon solar cells during phase I operation. Each PV power module requires two solar arrays with 32800 solar cells generating 18.75 kW of DC power for a total of 75 kW. The design incorporates an optimized thermal control system, pointing and tracking provision with the application of gimbals, and the use of orbital replacement units to achieve modularization. The design status of the PV power module, as derived from major tradeoff studies, is discussed at hardware levels ranging from component to system. Details of the design are presented where appropriate
