"储能电芯很缺""光伏链主企业还有五倍、十倍以上成长空间""2025第八届中国国际光伏与储能产业大会"传递出这些行业信息

Core Insights - The term "anti-involution" has become a prominent topic in the photovoltaic industry this year, highlighting the issue of excessive competition leading to price declines across various segments of the solar product supply chain [1][3] - The energy storage sector appears to be recovering faster than the photovoltaic industry, with a notable increase in demand for energy storage cells, despite some caution from industry participants regarding market conditions [1][2] Industry Overview - The photovoltaic industry is currently experiencing an oversupply situation, with significant price drops across the supply chain. For instance, prices for polysilicon, silicon wafers, batteries, and modules have decreased by approximately 10%, 20%, 15%, and 2% respectively since the beginning of the year [2] - Major companies in the photovoltaic sector are still facing operational pressures, with many reporting losses. However, recent quarterly reports indicate some recovery, with leading firms like Tongwei and Longi Green Energy showing reduced losses [2] Competitive Landscape - Companies are focusing on cost reduction and efficiency improvements while also pushing for innovation in response to the competitive pressures of "involution." The shift towards larger 210mm silicon wafers is seen as a way to enhance energy conversion efficiency [2] - The industry is urged to adopt a "big picture" mindset, balancing individual competitiveness with the overall health of the industry ecosystem to avoid detrimental competition [3][5] Technological Developments - New technologies in solar cells, such as perovskite and various combinations of existing technologies, are being explored, although stability and maturity remain concerns [6] - The energy storage market is witnessing a surge in demand, particularly for lithium iron phosphate batteries, driven by the declining costs of photovoltaic products and the economic viability of energy storage solutions [7][8] Market Dynamics - The energy storage sector is projected to grow significantly, with new installations expected to reach 73.76 million kilowatts by the end of 2024, accounting for over 40% of global installations and an annual growth rate exceeding 130% since the 14th Five-Year Plan [8] - The need for innovative business models and fair profit-sharing mechanisms among various stakeholders in the energy sector is emphasized to ensure sustainable growth and collaboration [9][10] Future Outlook - The photovoltaic industry is expected to achieve high-quality collaborative development over the next five to ten years, provided that anti-involution measures are effectively implemented [3][5] - The integration of energy storage with renewable energy sources is anticipated to create a more efficient and economically viable energy system, particularly in regions with high renewable energy generation [11]
