隆基森特BIPV：让钢铁行业屋顶成为“低碳增值引擎”

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].
