Another future development direction for high-power spacecraft solar arrays is the concentrator-type configuration, which will serve as a next-generation space solar array system tailored to meet the demands of high power output, low cost, and lightweight design.

Flexible solar arrays, characterized by their high mass-specific power, high stowage ratio, and easy scalability, have become an ideal solar array solution for future high-power spacecraft. This paper provides an overview of large-scale flexible solar array technology in aerospace engineering.

Flexible solar arrays utilize membrane structures as substrates. In the stowed state, each substrate panel remains tightly compressed. For large-area solar arrays, the stowed volume can be reduced to approximately one-tenth of that of rigid arrays.

Spaceborne solar arrays are the primary power source for spacecraft, converting solar energy into electrical power to sustain long-term operation. Over the past six decades, alongside advancements in space technology, solar arrays have evolved into three fundamental configurations: rigid, semi-rigid, and flexible, .
