Photovoltaic solar arrays are the principal means of converting solar energy to electrical energy for satellites. However, array configurations depend on the spacecraft stabilization concept, orbit parameters and power requirements.
The preliminary design of a geostationary communication satellite solar array is introduced in this work. Several of the considerations in the design of solar arrays are discussed: radiation effects on solar cells, substrates, selection of array voltage, analysis of shadows and overall performance.
Based on the power requirements for end of life EOL, power margin requirements and performance requirements, the number of panels, strings architecture and solar cells used on the solar array will be investigated.
