GUOTAI HAITONG SECURITIES·2026-01-26 11:14Investment Rating - The report assigns an "Accumulate" rating for the industry [1]. Core Insights - The market potential brought by space data centers is enormous, with crystalline silicon and perovskite battery technologies becoming key [2]. - The rapid development of commercial aerospace will benefit space photovoltaics significantly, as solar energy is the only reliable energy source in commercial aerospace, with solar irradiance in space being approximately 5-10 times that of ground photovoltaics [3][7]. Summary by Sections 1. Space Photovoltaics in Commercial Aerospace - Solar energy is a massive energy source, with the sun radiating energy equivalent to 130 trillion tons of coal annually, making it the largest exploitable energy source [7]. - Space photovoltaics are not affected by atmospheric interference, with solar irradiance around 1360 W/m², which is about 1.4 times that of ground photovoltaics [8]. 2. Successful Commercialization of Satellite Internet - Low Earth orbit (LEO) satellites have broad commercial application prospects, characterized by low transmission delays and costs, making them suitable for satellite internet applications [20]. - Companies like SpaceX's Starlink have successfully deployed LEO satellite constellations, enhancing global internet access [22]. 3. Development Opportunities - The mainstream energy solution in space is currently gallium arsenide (GaAs), but crystalline silicon and perovskite technologies are gaining traction due to their cost and efficiency improvements [48]. - The demand for space data centers is expected to grow significantly, with companies exploring the use of crystalline silicon and perovskite layered solutions [5]. 4. Market Outlook - If Elon Musk's goal of deploying 100 GW of AI computing power in space is achieved, it could lead to a demand for 680,000 satellites annually, compared to the current global stock of just over 10,000 satellites [5]. 5. Related Companies - Companies to watch in this sector include Junda Co., JinkoSolar, Trina Solar, Dongfang Risheng, and GCL-Poly Energy [5].
