Year: 2025
Type: article
Abstract: To meet the high power supply requirements of spacecraft, the research and development direction of ultra-large flexible solar array technology has been proposed based on increasing the power generation area of solar arrays and improving the irradiation intensity of incident light. By comparing and analyzing the development status of domestic and international Z-shaped folded solar arrays, fan-shaped flexible solar arrays, and roll-out flexible solar arrays, this paper highlights the advantages of flexible solar arrays, including compact stowed volume, lightweight design, high mass-to-power ratio, and re-deployable capabilities. Furthermore, it identifies key technical challenges faced by the roll-out flexible solar arrays in practical engineering applications providing insights to support future advancements in fully flexible solar array systems and their application in major aerospace missions.
