Photovoltaic glass belongs to the special glass, is the photovoltaic cell cover, at the same time play a role in transmitting light and protection of the battery sheet, photovoltaic glass than ordinary glass has a better visible light transmission, its visible light transmission ratio of more than or equal to 91.5%, can withstand high temperatures of more than 500 degrees, acid rain and harmful gases in the environment Europe a certain degree of corrosion resistance, and impact resistance is good. The main cost of photovoltaic glass is composed of raw materials of about 41%, fuel costs of about 41%, labor costs of about 4% and manufacturing costs of about 14%, of which the raw material of photovoltaic glass is mainly composed of soda ash and quartz sand. At present, the mainstream photovoltaic cell glass thickness in the market is divided into 3.2mm, 2.0mm two specifications, 3.2mm market share of more than 60%, with the lightweight components and new technologies continue to produce, the glass thickness will be to the development of thin film, 3.2mm market share will continue to be compressed, 2.0mm market share will be rapidly increased. 2021 China's photovoltaic glass market has exceeded 40 billion yuan, it is expected that in the next five years, people are still more than 40 billion yuan, and it is expected that in the next five years, people are still more than 40 billion yuan. In 2021, China's photovoltaic glass market size has exceeded 40 billion yuan, and is expected to maintain high growth in the next five years, with a compound annual growth rate of about 15%.
