Summary of China Solar Corporate Day Takeaways Industry Overview - The focus of the discussions was on Space-based Solar Power (SBSP) applications, highlighting both opportunities and challenges in the solar technology sector [1][2]. Key Companies Mentioned - **Maxwell**: Holds a 70% share of the global HJT cell equipment market [3]. - **Shenzhen SC**: Commands over 50% of the global Topcon cell equipment market [3]. - **HZ First**: Has over 60% share in the global film market with comprehensive packaging solutions [3]. Core Insights 1. **SBSP Demand Outlook**: - Participants believe SBSP demand is real and promising, driven by the rapid growth of Low Earth Orbit (LEO) satellite launches and the need to reduce satellite launch costs. Solar energy is viewed as the only viable long-duration renewable energy solution for space [7][6]. - The near-term demand is expected to be influenced by leading players' satellite launch plans, while long-term demand will be supported by solar cell cost reductions and efficiency improvements [7]. 2. **Technology Adoption Timeline**: - P-HJT and P-Topcon technologies are anticipated to see early adoption in the US by 2027, while multi-junction perovskite technology is expected to be adopted from 2029 onwards [6][10]. 3. **Equipment Orders**: - Initial R&D or trial orders are expected to benefit equipment manufacturers first due to uncertainties in the technology roadmap. The US is projected to be a key region for solar capital expenditure (capex) growth in the SBSP context [6][8]. - Maxwell has guided for RMB 6 billion in solar orders for 2026, primarily from overseas capacity expansion plans [8]. 4. **Entry Barriers**: - The SBSP application is likely to raise entry barriers for cell and module manufacturers due to increased R&D requirements and customer loyalty, despite low near-term volume visibility [9]. 5. **Technology Shift**: - The current dominant technology is Triple-junction GaAs, but there is a shift towards silicon-based and multi-junction perovskite technologies. The latter is seen as a promising long-term solution due to its potential for high efficiency and lower costs [10][12]. 6. **Challenges in Technology Development**: - Key hurdles for new technologies include advanced wafer cutting and packaging materials that can withstand space conditions. The need for thinner wafers and better radiation hardness is critical for space applications [12]. Additional Insights - The sentiment around capex expansion has improved, with both domestic and overseas customers showing increased interest in solar technology [8]. - The ability to gain trust from space customers and ensure ongoing quality inspections in space is viewed as a significant barrier for suppliers [9]. Conclusion - The discussions at the China Solar Corporate Day indicate a strong belief in the potential of SBSP applications, with significant opportunities for equipment manufacturers. However, challenges in technology development and market entry barriers remain critical considerations for stakeholders in the solar industry [1][7][9].
