When choosing between aluminum or steel solar mounting systems, weight becomes a crucial factor that directly impacts installation costs, structural requirements, and long-term performance. Aluminum weighs approximately one-third of steel (2.7 g/cm³ vs. 7.85 g/cm³), making it the preferred choice for rooftop solar installations where load-bearing capacity is limited. This significant weight difference translates into faster installation times, reduced structural reinforcement needs, and lower transportation costs across European construction …
