A research report on China's Solar Photovoltaic (PV) Glass Industry in 2024
Photovoltaic glass plays an important role as the special glass for the cover plate of solar cells It not only protects the solar panel from oxidation and corrosion by external moisture and gas, but also ensures that the components are not subjected to external forces The core performance of photovoltaic glass lies in its high transmittance, high strength and strong corrosion resistance These characteristics directly affect the life and power generation efficiency of photovoltaic modules.
The superior transmittance of photovoltaic glass is the key to improve the efficiency of power generation The higher the transmittance, the higher the power generation efficiency of photovoltaic modules Ultra-white glass has become the only choice for making photovoltaic glass because of its excellent light transmission performance It is made by deep processing such as toughening, coating and glaze plating to achieve the required physical and chemical characteristics The iron content of ultra-white glass is less than 0.015%, which is much lower than that of ordinary glass, thus ensuring a light transmittance of over 91.5%, which is about 3% higher than that of ordinary tempered glass In addition, the low content of impurities such as nickel sulfide in ultra-white glass enhances its impact resistance and improves its explosion-proof rate According to the difference of manufacturing process and application scenario, photovoltaic glass can be divided into ultra-white calendered glass and ultra-white float glass Ultra-white calendered glass is mainly used in crystalline silicon battery modules, while ultra-white float glass is more used in thin film battery modules In the current market, ultra-white calendered photovoltaic glass has become the mainstream photovoltaic glass type because of its high light transmittance and crystalline silicon battery modules occupy the main market share.
China's photovoltaic glass industry is currently in a stage of rapid growth, which is mainly driven by the increase in installed capacity of photovoltaic modules and the increase in permeability of double glass modules Under the guidance of the national carbon peaking and carbon neutralization strategy, the proportion of clean energy use in China is increasing, and photovoltaic power generation occupies an important position Since 2018, the proportion of new photovoltaic power generation in new infrastructure power generation in China has increased to 12.9% in 2021 This trend reflects China's important progress in the field of clean energy and the rapid development of photovoltaic industry.
At present, China has become the country with the largest installed capacity of PV in the world It is estimated that by 2026, the installed capacity of PV in China will reach about 1000GW The rapid growth of photovoltaic module installed capacity not only promotes the photovoltaic industry, but also brings huge growth opportunities for the photovoltaic glass industry China Photovoltaic Industry Association (CPIA) predicts that the penetration rate of double-glass photovoltaic modules will continue to increase in the future As the demand of double-glass photovoltaic modules is greater than that of single-glass modules, this will further promote the growth of photovoltaic glass industry
