The clean energy industry is a backbone force in achieving the dual carbon goals. As one of the most economically viable clean energies, the economic feasibility of replacing fossil fuels with photovoltaics has been recognized and supported globally.
LONGi Green Energy Technology Co., Ltd. (LONGi Green Energy), which has been deeply engaged in the field of photovoltaic manufacturing for more than 20 years and has been awarded the national “Green Factory”, is a model of reducing industry costs, reducing carbon dioxide emissions, and extending battery life with scientific and technological R&D and technological innovation.
Through LONGi’s efforts, PV modules have been reduced from US$2/W to about 2 cents/W, which has strongly promoted the global adoption of clean energy. The green circular economy carried out by it has enabled 100% of the 14 transportation lines between silicon wafers and cell bases to use recycled packaging, with an average annual cost reduction of 23 million yuan, which has not only greatly improved its own economic benefits, but also accelerated the transition of the photovoltaic industry from “manufacturing” to “green intelligent manufacturing”.
Push the boundaries of technical product performance
Since 2012, LONGi has invested a total of 22 billion yuan in R&D for scientific research, obtained more than 2,500 special projects of various kinds, and refreshed the world record for photovoltaic conversion efficiency of solar cells more than ten times.
Through scientific and technological R&D and innovation, LONGi Green Energy has become the world record holder of crystalline silicon single-junction cells and crystalline silicon-perovskite tandem cells. Among them, it has developed Terui silicon wafers with superior electrical and mechanical properties, produced high-efficiency photovoltaic module products for different use scenarios, helped more regions use clean energy, enriched application scenarios, and contributed to global green and low-carbon development. Developed fluorine-free solar backsheets to reduce the use of fluorine and pollution; At the same time, the product recycling standard is improved, and the recycling rate of its photovoltaic cell products can reach 100%.
At the same time, LONGi Green Energy has achieved 100% visibility of customer order status by building an online platform for visualization of the whole process of transportation status, and has carried out the integrated construction of logistics warehouse network, adopted the model of “overseas railway-offshore barge-inland water transport-cross-strait ferry”, reached strategic cooperation with ports and logistics enterprises, efficiently deployed multiple resources, replaced warehouses with containers, improved resource utilization efficiency, and built a sustainable, intelligent and information-based green logistics system.
It is reported that LONGi Green Energy has built the first “zero-carbon factory” in the photovoltaic industry at its Baoshan production base in Yunnan. By the end of 2023, LONGi’s cumulative wafer shipments reached 414.24 GW, accounting for 27% of the world’s cumulative installed PV capacity, which can generate 1,736.1 billion kWh of green electricity, equivalent to reducing 812 million tons of carbon dioxide emissions. According to statistics, more than 30% of the silicon wafers of all installed solar power systems in the world come from LONGi Green Energy.
Expand the green energy ecosystem
Today, LONGi Green Energy has gradually grown into the largest private enterprise in Shaanxi Province, not only carrying the banner of integrating into the national strategy, basing itself on the industry, and promoting green development, but also actively expanding foreign cooperation and continuously integrating into the global industrial chain value chain.
In 2018, at the 24th United Nations Climate Change Conference, LONGi Green Energy first proposed the concept of “Solar for Solar”, that is, to use “clean energy (solar energy)” to manufacture “clean energy (electricity)”. Since 2020, LONGi has successively joined international carbon reduction organizations such as RE100, EP100, EV100, and SBTi, becoming the first Chinese enterprise to join four international initiatives at the same time. Since joining the Science Based Targets (SBTi) initiative, LONGi Green Energy has established a greenhouse gas emission accounting system covering the whole value chain of the SBTi initiative, and simulates the trend of emissions under different scenarios in the future according to the SBTi setting method, and proposes emission reduction targets that meet the requirements of the SBTi and adapt to the development stage of the enterprise. In 2023, LONGi Green Energy officially passed the SBTi audit and certification, becoming the first enterprise in China’s photovoltaic industry to obtain this audit certification.
“LONGi Green Energy has always adhered to the concept of green production.” According to the relevant person in charge of LONGi Green Energy, in terms of production management, LONGi Green Energy uses real-time AI accurate traceability technology of image features to solve the problems in the photovoltaic module production industry such as the inapplicability of traditional barcode traceability and the low accuracy of virtual code traceability, and build the first “lighthouse factory” in the global photovoltaic industry. In terms of collaborative innovation, LONGi Green Energy officially launched the STAR innovation ecosystem collaboration platform with the purpose of openness, sharing, innovation and win-win to the world, promoting the transmission of innovation trends, soliciting global ideas, integrating solutions, docking high-quality resources, and promoting technological innovation in the global photovoltaic industry. At present, it has formed a solid collaborative innovation R&D body with the R&D teams of universities such as the University of New South Wales and Lanzhou University in Australia, and has carried out collaborative innovation research and development on some key core technologies with partners such as Laplace and Deer Laser.
“LONGi Green Energy will continue to increase investment in technological innovation, green and low-carbon, responsible management and diversity and inclusiveness, build a global green ecosystem, and insist on making the voice of Chinese enterprises in the field of carbon emission reduction, making practical actions and making a positive impact.” said the above-mentioned person in charge.
