Aluminum-magnesium plated sheet's revolutionary application in the photovoltaic field
Under the backdrop of continuously rising PV installation capacity, aluminum-magnesium coated plates are reshaping the market landscape of support materials. The combination of their lightweight characteristics (density 12% lower than galvanized plates) and high strength (yield strength up to 450MPa) reduces steel consumption for single megawatt supports by 18% and lowers transportation costs by 25%. More importantly, their over 30-year corrosion resistance life matches the 25-year operational cycle of photovoltaic power stations, avoiding the maintenance pain points of traditional galvanized supports that require replacement every 8-10 years. Empirical data from Qinghai's Talatang PV base shows that power stations using aluminum-magnesium coated supports have an annual power generation loss rate 0.3% lower than that of galvanized supports, which, over a 30-year period, equates to an additional 120 million kWh of electricity generated. Currently, leading companies such as Longi and Trina Solar have included aluminum-magnesium coated supports in their standard configurations, driving the industry towards lifecycle cost optimization and transformation.
