Dongkuk Metal Mill introduced on Dec. 1 that it has developed the world’s first ultra-high reflectance photo voltaic cell coloration metal sheet solely for photo voltaic functions, based mostly on its proprietary three-element high-corrosion-resistant plating expertise.
The corporate’s new metal sheet is characterised by maximized reflectance in comparison with present merchandise. Contemplating that photo voltaic panels are transitioning to bifacial sorts, Dongkuk decided that rising the floor reflectance of coloration metal sheets used as roofing supplies may enhance the ability era effectivity of photo voltaic modules, and accomplished product growth after roughly one 12 months of analysis and growth.
Whereas present supplies have a complete mild reflectance of 50-60%, Dongkuk’s photo voltaic cell coloration metal sheet has elevated reflectance to 80-85%. This can be a stage that present architectural supplies for roofing can’t obtain. When the brand new metal sheets are utilized, the ability era effectivity of bifacial photo voltaic modules improves by 30%.
Dongkuk has resolved the corrosion downside, which is the most important weak spot of roofing supplies. Roofs are straight uncovered to environments with excessive temperature, excessive humidity, ultraviolet rays, condensation, and acid rain, and corrosion can happen when rain or snow seeps between panel metal plates.
Dongkuk included three-element plating expertise to safe corrosion resistance greater than twice that of present galvalume metal sheets by exact management of zinc, aluminum, and magnesium ratios and particular processes. Workability was additionally improved by greater than twice to make sure no materials injury even after bending processes. Dongkuk utilized a ‘two-layer construction design’ to otherwise design the entrance floor of metal sheets uncovered to daylight and the rear floor in touch with glass wool, thereby enhancing corrosion prevention capabilities.
Choi Woo-chan, director of Dongkuk Metal Mill’s Expertise Analysis Institute, said, “This next-generation premium materials boasts overwhelming reflectance and corrosion resistance even in excessive environments, and may obtain energy-saving results similar to cool roofing the place roof temperature decreases as a result of elevated reflectance. With the enlargement of the worldwide photo voltaic market, enhance in bifacial modules, and acceleration of insurance policies similar to RE100, it’s anticipated to determine itself as a core materials within the photo voltaic and eco-friendly development sectors sooner or later.”
