Rollar Solar Array by Galaxyspace Define satellite compactness and power efficiency
Galaxyspace, a commercial space company based in Beijing, has introduced a groundbreaking rollable solar panel that drastically reduces satellite bulk and stimulates energy efficiency. Presented at a recent conference in Yibin, the new sun wing can be compacted to the size of a water bottle, but unfolds in a track to cover 20 square meters.
Xu Ming, CEO of Galaxyspace, explained that the solar panels were wrapped as rolls around the satellite before the launch and extend to more than 10 meters long and almost two meters wide in the room. “Although it includes 20 square meters, about the size of a meeting room, it can be rolled to the diameter of a water bottle,” he said.
The company claims that the fully flexible panel supplies the energy density of traditional rigid arrays four times, which offers a lighter, more compact solution that is ideal for launches with multiple satellite. This progress also improves the lifespan of the orbital for internet satellite constellations.
Galaxyspace has launched 25 own satellites, including the world’s first millimeter-wave satellite with low earthbit with high frequency and the first flat, stackable satellite from China equipped with flexible solar panels.
In February the company demonstrated direct-to-cell technology and connected users in both Beijing and Thailand via its broadband Leo Constellation and a ground station located in Beijing.
The Nantong -based Smart Factory now produces 100 to 150 medium satellites per year. The automated production line uses robot arms for precision assembly. “Supported by assembler robots, intelligent equipment and digital production systems, we have set up a complete production chain for satellites ranging from 100 to 2,000 kilograms,” said Cheng Ming, the head of the factory.
Galaxyspace, founded in 2018, emerged as a leader in the Chinese satellite internet industry and became the first unicorn of the country in the commercial room sector.
