In the past year, the entire photovoltaic industry chain, from upstream polysilicon and silicon wafers, to midstream photovoltaic glass and solar cells, to downstream inverters and modules, has achieved leapfrog development.
Why does this phenomenon occur? It turns out that China’s photovoltaic industry has firmly occupied three “world firsts”: As early as 2017, my country’s photovoltaic industry accounted for more than 70% of the world’s share, and its scale and production capacity were the largest in the world; in addition, China’s photovoltaic power generation installed capacity was the world’s largest. Since 2013, China's annual new photovoltaic installed capacity has ranked first in the world for five consecutive years, and in 2017， it exceeded 50% of the world's new installed capacity.
From the perspective of the industrial chain, China is a well-deserved global leader. In 2019, China Silicon Materials, silicon wafers, solar cells, and modules accounted for 67%, 98%, and 77% of global output, respectively.
Different from the last round of global expansion of China's photovoltaic industry, today's photovoltaic market is not only concerned with price, but also with product quality and efficiency. technological innovation has become the core competitiveness that promotes the
As an indispensable bonding and sealing material for its development, the sealant must have excellent structural adhesion to various component materials such as special aluminum, tempered glass, TPT/TPE composite backing material, and junction box PPO. The design service life of solar photovoltaic systems is generally more than 20 years. Therefore, good corrosion resistance, weathering resistance, high and low temperature resistance are also one of the indicators to measure the sealant for photovoltaic modules.
In the future, BAIYUN will also participate more deeply and extensively in the construction of the photovoltaic industry, leaving a low-carbon footprint on the road to my country's green energy transformation, and building a beautiful world together.
