Chan Ye Xin Xi Wang·2026-02-25 01:26Core Viewpoint - The Chinese photovoltaic backsheet industry exhibits a fluctuating market scale, with growth driven by policy support and installation expansion from 2015 to 2017, followed by a downturn due to regulatory adjustments and price declines in 2018-2019. The market rebounded from 2020 onwards, reaching 8.5 billion yuan in 2022, but is expected to decline in 2023-2024 due to increased penetration of bifacial modules and intensified price competition [1][14]. Industry Overview - Photovoltaic backsheets are essential encapsulation materials located at the back of photovoltaic modules, providing protection against environmental factors and ensuring insulation [2][5]. - The structure of photovoltaic backsheets typically consists of five layers, with the outer layer made of PVDF for environmental resistance, a middle layer of PET for insulation, and inner layers of PVDF and EVA for adhesion [2][4]. Market Dynamics - The market for photovoltaic backsheets is influenced by the rapid penetration of bifacial modules, increased competition in traditional backsheet pricing, and adjustments in the global photovoltaic supply chain [1][14]. - The market scale reached 8.5 billion yuan in 2022, but is projected to decline in 2023-2024 due to various factors [1][14]. Industry Policies - The photovoltaic industry is supported by national policies aimed at promoting renewable energy, which has led to significant growth in both scale and technology within the sector [5][13]. - Policies such as the "14th Five-Year Plan for Renewable Energy Development" aim for renewable energy consumption to reach 18% of total energy consumption by 2025 [13]. Industry Chain - The photovoltaic backsheet industry has a complex supply chain, with upstream materials including PVDF, PVF, PET, and glass. Domestic materials have increasingly met performance and quality standards, reducing reliance on foreign suppliers [5][7]. - The midstream involves the manufacturing of backsheets, while the downstream is focused on application within the photovoltaic industry [5][6]. Market Share of Materials - The primary materials used in photovoltaic backsheets include PVDF (53%), PVF (15%), glass (14%), PET (10%), and others, with PVDF being the dominant material due to its superior properties [7][8]. Competitive Landscape - The market is characterized by a high concentration of leading domestic companies such as Zhonglai Co., Foster, and Saiwu Technology, with significant production bases primarily located in Jiangsu and Zhejiang provinces [15][16]. - In 2024, the estimated shipment volumes for major companies are projected to be 135 million square meters for Zhonglai, 100 million for Foster, and 89 million for Saiwu [15]. Development Trends - The industry is expected to see advancements in flexible photovoltaic backsheet technology, ultra-thin and lightweight materials, and the integration of smart functionalities into backsheets [17][18][19]. - These innovations aim to enhance adaptability, reduce costs, and improve the overall efficiency and reliability of photovoltaic systems [17][18][19].
