Overview - The report maintains a "stronger than market" rating for the renewable energy sector, highlighting that the demand for offshore wind power in China and Europe is increasing, leading to a rise in foundation demand and profit recovery for wind turbines. The "anti-involution" policy is expected to continue driving the photovoltaic sector, particularly with the expansion of perovskite technology. Overall, while short-term installation demand for renewable energy globally may be weak, there are structural opportunities in the market [1]. Key Points Supporting the Rating - The "anti-involution" trend is stabilizing wind turbine prices, enhancing profitability for manufacturers. China's offshore wind projects are becoming economically viable, contributing significantly to installed capacity. The demand for offshore wind in Europe and emerging markets is also on the rise [3]. - In the photovoltaic sector, the "anti-involution" policy remains the main theme, with a focus on the potential for capacity exits in battery and module production, as well as the industrialization potential of perovskite technology. Investment should prioritize growth-oriented new technology directions and the main industry chain benefiting from the "anti-involution" trend [3]. Investment Recommendations - For wind power, the report suggests prioritizing investments in the turbine segment, which is expected to recover profitability, and in the foundation segment that is progressing quickly in Europe. The offshore wind market is projected to grow significantly, with a focus on deep-sea projects [3]. - In the photovoltaic sector, the report emphasizes the importance of monitoring the "anti-involution" policy's impact on the industry, particularly regarding the exit of inefficient capacity and the enhancement of efficiency in battery and module production [3]. Long-term Outlook for Renewable Energy Demand - The report indicates that China's renewable energy demand is expected to remain robust in the long term, with an average annual installation capacity of over 400GW projected from 2025 to 2035. This is driven by the country's energy security needs and the ongoing transition to a low-carbon economy [13][16]. - The "136 Document" is noted for guiding the development of renewable energy projects towards market-oriented pricing, which is expected to stabilize project returns and promote high-quality development in the sector [31]. Photovoltaic Sector Insights - The report anticipates a moderate decline in photovoltaic installations in 2026 due to a phase of pre-installation in 2025, with projected installations of 290GW in 2025 and 180GW in 2026, reflecting a year-on-year decrease of 38% [33]. - The report highlights that the European photovoltaic market is facing growth challenges, with a forecasted installation of 64.2GW in 2025, indicating a slight decline. The U.S. market is also expected to experience pressure on growth due to policy adjustments [34][37]. Perovskite Technology Potential - Perovskite technology is identified as a key area for enhancing competitiveness in the photovoltaic manufacturing sector, with expectations for significant breakthroughs in industrialization by leading manufacturers in 2026 [33][44].
