Photovoltaic glass is the glass used for photovoltaic modules, it is been widely used as the cover glass of ordinary photovoltaic modules, the cover plate and back plate glass of double glass component, and the cover plate and back plate glass of double glass component. At present, photovoltaic modules are divided into ordinary modules and dual glass modules, while the structure of the two is distinguished as follows.
Compared with ordinary modules, dual glass modules have the advantages of a long-life cycle, more significant power generation during the life cycle, higher power generation efficiency, and slower attenuation.
After ten years of rapid development, the domestic photovoltaic glass industry has formed advantages in terms of the quality and cost of photovoltaic glass, which makes the global market share of photovoltaic glass in China stable at more than 90% for many years, and maintains the market position of the world's major photovoltaic glass suppliers.
In recent years, with the establishment of factories overseas by domestic module companies, the demand for photovoltaic glass has gradually increased overseas. In addition to the export in the form of photovoltaic glass sheets, photovoltaic glass is also exported in the form of photovoltaic modules. In 2020, Chinese photovoltaic module export volume was 78.8GW, an increase of 18.3% year-on-year. Exports amounted to $16.99 billion, accounting for 86% of total exports of photovoltaic products. The export areas of Chinese photovoltaic products are Europe, Vietnam, Japan, Brazil, and other international markets.
In addition, conventional double-glass modules and double-sided double-glass modules began to be widely used. Double glass modules have anti-PID, anti-snail grain, anti-crack, anti-sand, anti-salt spray, anti-humid heat, and other high reliability has become the industry consensus. In regard to the areas with stringent natural conditions, double glass components with reliability advantages have almost become the standard.
