Zhong Guo Neng Yuan Wang·2026-01-07 01:37Core Insights - The report by Dongwu Securities highlights the significant role of solar wings in satellite power systems, which account for approximately 20-30% of the total manufacturing cost of satellites, with solar wings representing over 60% of the value [1][2] - The global satellite launch volume is projected to increase dramatically, from 237 satellites in 2016 to over 4,300 by 2025, reflecting a compound annual growth rate (CAGR) of 34% [2] - The demand for solar wings is expected to rise due to the increasing power requirements of satellites, with SpaceX's Starlink V3 satellites showing a more than tenfold increase in solar wing area compared to earlier versions [1][2] Industry Trends - The advancement of reusable rocket technology has significantly reduced launch costs, breaking down economic barriers to space access [2] - The global deployment of low Earth orbit (LEO) satellites is entering a rapid growth phase, with over 100,000 satellites registered globally, driven by countries seeking to secure strategic orbital and frequency resources [3] - The increasing demand for AI computing power is pushing computational resources into space, leveraging the advantages of solar energy and thermal conditions in near-Earth orbit [3] Technological Developments - Gallium arsenide (GaAs) is the dominant technology in the industry, offering high efficiency and radiation resistance, but its high cost (20-40 million per square meter) may limit large-scale satellite constellations [3] - Alternatives such as perovskite solar cells show promise due to their lightweight, high energy-to-weight ratio, and lower costs, potentially becoming a superior solution for space power [3] Investment Opportunities - The report suggests that the development of commercial space and LEO satellites will accelerate the growth of space photovoltaic power, with ground-based efficient perovskite and silicon tandem technologies being critical [4] - Recommended companies include Junda Co., Ltd. (002865) for its collaboration in satellite perovskite, and Mingyang Smart Energy (601615) for its focus on perovskite and GaAs technologies [4] - Other companies to watch include Dongfang Risheng (300118), GCL-Poly Energy (and others in the HJT/perovskite battery sector), as well as core equipment manufacturers like Maiwei Co., Ltd. (300751) and Jiejia Weichuang (300724) [4]
