15 August, The official website of Longji Green Energy released the "Xi'an Longji Leye Photovoltaic Technology Co., Ltd. (Hereinafter referred to as" Longji Leye ") Xi'an Longji Leye Battery R & D Project Group Environmental Impact Assessment Pre-approval Announcement".
The announcement shows that the project is a technological transformation project, located within the planning scope of the second phase of Xi'an National Civil Aerospace Industry Base, and the project covers two plots, north and south. Longji Leye will build a pilot line of high-efficiency monocrystalline silicon solar cells with an annual output of 800MW in the north plot through technical transformation; A 400 MW high-efficiency monocrystalline silicon solar cell pilot line and a 400 MW high-efficiency monocrystalline module pilot line will be constructed in the south block through technical transformation . The project is planned to invest 65 million yuan .
Among them, the light conversion rate of the cell developed by South Area 16B is 27.8 ± 0.3%, the light conversion rate of the module developed by South Area 16B is 24.8 ± 0.3%, and the light conversion rate of the cell developed by North Area 1A is 27.3 ± 0.3%.
At present, the above technological transformation projects have obtained the confirmation of the record of enterprise investment projects in Shaanxi Province.
Previously, in 2021, Longji Leye implemented the first phase project of Xi'an Longji Leye Battery Research and Development Project Group (hereinafter referred to as "Phase I Project") and the second phase project of Xi'an Longji Leye Battery Research and Development Project Group (hereinafter referred to as "Phase II Project") in the north-south factory area, both of which are independent projects. The environmental protection acceptance of completion was carried out in 2023.
The first phase of the project has built a 400MW cell small test line and a 400MW module small test line in the south area, and the second phase of the project has built a 360MW PERC cell small test line and a 380MW TOPCon cell small test line in the north area.
The EIA report (public draft before approval) shows that the above technical transformation project is an independent project, which is based on the first and second phase of the above project, and has no connection with other existing pilot lines and production lines of Longji Green Energy. The differences between the three pilot R & D lines of the above technical transformation and the original R & D line are as follows:
