下一个光伏大风口：不是地面，而是太空！

Core Viewpoint - The global commercial space industry is experiencing rapid growth, driven by the explosive demand for AI computing power, with space photovoltaic technology emerging as a promising investment opportunity due to its cost-effectiveness and advantages over terrestrial solar power [5][10]. Group 1: Industry Growth and Policy Support - The commercial space sector is entering a high-growth phase, with the number of satellites in orbit expected to exceed 11,605 by the end of 2024, dominated by the US at 76% and China at around 9% [6]. - In the first half of 2025, China's satellite launches are projected to increase by 92% year-on-year, significantly outpacing the global average, supported by government policies that emphasize the importance of commercial space [8]. - The Chinese government has included commercial space in its "new quality productivity" category and has committed to developing space energy technologies, providing clear policy support for space photovoltaic technology [8][10]. Group 2: Advantages of Space Photovoltaics - Space photovoltaics have significant advantages over terrestrial solar power, including better sunlight conditions, with solar intensity in space being 36% higher, and the ability to generate power continuously without the need for energy storage systems [12]. - The technology for space photovoltaics is evolving, with three main types of solar cells: gallium arsenide, crystalline silicon, and perovskite, each with distinct advantages and challenges [14]. Group 3: Market Potential and Economic Viability - The current market for space photovoltaics is limited due to high launch costs, but it is expected to grow steadily, with projections indicating a market space of approximately 3 billion yuan from 2026 to 2030, increasing to 12 billion yuan from 2030 to 2035, and further to 25 billion yuan from 2035 to 2040 [17]. - A significant factor for the future market potential of space photovoltaics is the reduction in launch costs, which currently stand at $3,600 per kilogram. If costs can be reduced to $200-$300 per kilogram, the demand for space photovoltaics could see explosive growth, potentially reaching a market size of 500 billion yuan annually [19]. Group 4: Investment Opportunities - The growth of space photovoltaics is directly linked to the high demand in the commercial space sector, with photovoltaic equipment manufacturers, particularly those specializing in HJT and perovskite technologies, expected to be the biggest beneficiaries [21]. - Companies involved in the production of HJT and perovskite battery equipment, as well as ultra-thin silicon wafer cutting, are recommended for investment as the industry demand continues to rise [21].
