From March 12 to 14, 2026, the Shanghai Commercial Aerospace Conference and Exhibition will be held at the Shanghai Pudong International Expo Center, showcasing a variety of new aerospace products developed by the Shanghai Academy of Space Technology under China Aerospace Science and Technology Corporation. The rollable flexible solar array is one of the "star products" at this Shanghai Commercial Aerospace Conference. This product features a flexible deployment mechanism and a highly integrated flexible film substrate, which can be tightly rolled onto a spool with a diameter of less than 100mm before launch, closely adhering to the satellite body. After entering orbit, it smoothly unfolds relying on the energy storage deployment mechanism, forming a large area of continuous power generation surface, like a space painting gradually unfurling, achieving a seamless transition from "extreme storage" to "efficient power supply."
