1. Overview of the Photovoltaic Glass Industry

The key role and development prospects of photovoltaic glass in the solar energy industry

Photovoltaic glass, as the core material for solar cell cover plates, plays a vital role in solar power generation systems. It not only protects solar cells from external moisture and gas oxidation and corrosion but also effectively prevents components from being damaged by external forces, ensuring the long-term reliable operation of photovoltaic modules. With the increasing global demand for renewable energy, the market demand for photovoltaic glass is rapidly growing, and its technological innovation and performance improvement have played an important role in promoting the development of the photovoltaic industry.

1. The performance of photovoltaic glass and its impact

The core performance of photovoltaic glass includes high light transmittance, high strength, and strong corrosion resistance, which directly affect the lifespan and power generation efficiency of photovoltaic modules. Among these, light transmittance is a key factor determining the efficiency of photovoltaic power generation. The higher the light transmittance of photovoltaic glass, the more solar energy is absorbed by the photovoltaic module, resulting in higher power generation efficiency.

In photovoltaic glass, ultra-white glass has become the preferred material due to its extremely high light transmittance.. Compared with ordinary glass, ultra-white glass has an iron content of less than 0.015%, which greatly enhances its light transmittance to over 91.5%, about 3% higher than ordinary tempered glass. In addition, low levels of impurities such as nickel sulfide in ultra-white glass also enhance its impact resistance, further improving its explosion-proof capability. Photovoltaic glass typically undergoes processes such as tempering, coating, and glazing during production to achieve the required physical and chemical properties, ensuring stable performance under extreme weather conditions.

2. Current development status of China's photovoltaic glass industry

China's photovoltaic glass industry is entering a phase of rapid development, driven mainly by a significant increase in installed capacity of photovoltaic modules and a continuously rising penetration rate of double-glass modules. According to data from the China Photovoltaic Industry Association (CPIA), since 2018, the proportion of newly added power generation from photovoltaic power in new infrastructure has been steadily increasing, reaching 12.9% by 2021. This trend reflects China's significant progress in clean energy, with the photovoltaic industry becoming a core component.

As of now,China has become the country with the largest installed capacity of photovoltaics in the world, and it is expected that by 2026, China's installed capacity will reach 1000GW. The rapid development of the photovoltaic industry has brought enormous market opportunities for the photovoltaic glass industry. According to market research forecasts, the penetration rate of double-glass photovoltaic modules will significantly increase in the future; it is expected that by 2027, installed capacity for photovoltaic glass will grow to between 5.231 million tons and 6.381 million tons, with an annual compound growth rate between 6.6% and 7.5%. Double-glass photovoltaic modules require more photovoltaic glass, which will inevitably drive continuous growth in the entire photovoltaic glass industry.

3. The industrial chain and cost structure of photovoltaic glass

Photovoltaic glass is located in the midstream segment of the photovoltaic industrial chain.Its upstream includes raw materials such as quartz sand and soda ash as well as fuels like natural gas.Downstream involves packaging and integration of photovoltaic modules for final application in solar power generation systems. In terms of production costs for photovoltaic glass, raw materials account for 48%, mainly including quartz sand and soda ash, while fuel costs account for 39%. Particularly, ultra-white quartz sand resources are relatively scarce and are mainly distributed in regions such as Anhui, Hunan, Guangdong, Guangxi, and Hainan in China; companies with their own quartz sand resources have a significant competitive advantage in production costs.
