Core Viewpoint - The steel industry is facing challenges from rising energy costs and stricter carbon emission regulations, making green transformation essential for sustainable development. Longi Sente BIPV provides efficient green electricity solutions to activate space value and create new resource utilization paths for steel companies [1][2]. Group 1: New Plant Construction - Longi Sente BIPV integrates green power generation solutions with new plant construction, maximizing energy efficiency. The Baowu Taigang hot-rolling plant project exemplifies this approach, incorporating an 11MW Longi system from the start, which avoids resource waste and ensures every inch of roof space is utilized for power generation [1]. - The project is expected to reduce carbon emissions by approximately 240,000 tons over its lifecycle, saving significant energy costs and providing a competitive advantage in carbon asset accumulation [1]. Group 2: Old Plant Renovation - The renovation of old plants addresses common issues such as roof leaks and high maintenance costs. The Baowu New Steel silicon steel plant project serves as a model, implementing a 2.55MW Longi system that eliminates leakage risks and significantly reduces maintenance expenses while generating 55.5 million kWh of electricity over its lifecycle [2]. - This "renovation instead of repair" model transforms old roofs into sustainable "green assets," offering a replicable path for the renovation of aging facilities across the steel industry [2]. Group 3: Curved Roof Adaptation - Longi Sente BIPV has successfully installed photovoltaic systems on curved roofs, previously considered unsuitable for solar applications. Projects at Shan Steel Long Steel and Jiangsu Changqiang Steel achieved installed capacities of 8.73MW and 18.12MW, respectively, by using a "follow slope" installation method [2][4]. - These projects demonstrate that there are no unsuitable roofs, only solutions that have not been identified, unlocking previously unusable curved roof resources and generating significant electricity over their lifecycles [4]. Group 4: Dusty Environments - The steel production environment often generates dust, which can hinder the efficiency of photovoltaic systems. Longi Sente BIPV incorporates a dust prevention design that allows for self-cleaning through rainwater, reducing maintenance costs and preventing power loss due to dust accumulation [6]. - This design can enhance electricity generation by 6% compared to traditional photovoltaic products, further increasing profitability for steel companies [6].

Core Insights - The steel industry is facing dual challenges of rising energy costs and tightening carbon emission regulations, making green transformation essential for sustainable development [1] Group 1: New Construction - Longi Sente BIPV integrates efficient green electricity solutions into new steel plant constructions, maximizing energy efficiency and utilizing rooftop resources effectively, as demonstrated by the Baowu Tai Steel hot-rolled plant project with an 11MW Longi system [2] - The project aims for a "green start," achieving a total carbon reduction of approximately 240,000 tons over its lifecycle, providing significant energy cost savings and a competitive edge in carbon asset accumulation [2] Group 2: Renovation of Old Facilities - The renovation of aging steel plants, such as the Baowu New Steel silicon steel plant, addresses common issues like roof leaks and high maintenance costs by implementing a 2.55MW Longi system [3] - This renovation approach not only prevents leaks but also generates an estimated 55.5 million kilowatt-hours of electricity over its lifecycle, transforming old roofs into profitable "green assets" [3] Group 3: Adaptation to Unique Roof Structures - Longi Sente BIPV has successfully installed photovoltaic systems on curved roofs, previously considered unsuitable for solar applications, achieving capacities of 8.73MW and 18.12MW at projects in Shan Steel Long Steel and Jiangsu Changqiang Steel [4] - These projects demonstrate that with the right solutions, previously unusable rooftop resources can be activated, generating 227 million kilowatt-hours and 445 million kilowatt-hours of electricity over their lifecycles [4] Group 4: Dust Management Solutions - The steel production environment generates significant dust, which can hinder photovoltaic efficiency; however, Longi Sente BIPV incorporates dust prevention designs that allow for self-cleaning through rainwater, enhancing operational efficiency [5] - This design can increase electricity generation by 6% compared to traditional photovoltaic products, thereby expanding profit margins for steel companies [5] Group 5: Collaboration and Innovation - The collaboration between Longi and Sente exemplifies the precise integration of photovoltaic and architectural technologies, pushing the boundaries of energy conversion efficiency with Longi's BC cells and Sente's robust structural foundations [6] - The BIPV solutions provided by Longi Sente demonstrate that every rooftop challenge in the steel industry has a corresponding green solution, supporting cost reduction and carbon emission goals [6]
