Summary of Conference Call Notes Industry Overview - The flexible solar wing application is expected to increase significantly, driven primarily by multi-satellite launches and the need for enhanced energy density [1][2] - UTG (Ultra-Thin Glass) and CPI (Transparent Polyimide) are the main flexible packaging materials, with UTG outperforming CPI in light transmittance, oxidation resistance, and high-temperature resistance [1][2] Key Points and Arguments - **Material Comparison**: - UTG has a light transmittance that is 5-6% higher than CPI, which directly impacts the efficiency of solar cell light absorption and conversion [3] - UTG can withstand temperatures of 700-800 degrees Celsius, while CPI only withstands 70-80 degrees Celsius, leading to a significant difference in thermal degradation performance [3] - The lifespan of UTG is over 10 years compared to 3-5 years for CPI, making UTG more suitable for large-area solar wings [2][3] - **Market Demand**: - The Starlink V3 version is expected to adopt 70% UTG, with a total demand of approximately 9 million square meters for 3.5 billion satellites [5] - Domestic plans from Xingwang and State Grid indicate a demand of about 560 million square meters for 28,000 satellites, leading to a total demand of 15 million square meters [5] - Elon Musk's plan for deploying 100GW of space solar energy requires 400 million square meters of solar area, indicating a market potential for UTG far exceeding current estimates [5] Investment Recommendation - **Kaisong Technology**: - It is the only A-share company capable of fully autonomous production of UTG across the entire industry chain, providing a cost advantage and meeting domestic satellite localization requirements [6] - The company has made rapid progress in the commercial aerospace sector, having sent samples to research institutions and perovskite companies, with a shipment volume reaching the thousand-piece level [6] - Kaisong Technology is expected to benefit first from downstream demand expansion, making it a recommended investment target [6][7] Additional Important Information - The transition from rigid or semi-rigid solar wing solutions to flexible solutions is anticipated to create a market space close to hundreds of billions or even trillions [2] - UTG's superior thermal expansion performance makes it more suitable for large solar wings, which is crucial for future applications [2][3]
