What is the maximum mechanical load for DualSun panels?
During certification testing of the DualSun panels, the TÜV Rheinland laboratory results demonstrate that the DualSun panels with the appropriate mounting system can resist a maximal positive mechanical load (ex. snow) of 5.400 Pa and maximum negative load (ex. strong winds) of 2.400 Pa. Moreover, the DualSun Wave panel (stainless steel version) underwent additional tests and can resist a max positive load of 6.600 Pa, which is particularly important for installations in high-altitude mountain ranges.
For the DualSun Spring panel, here is part of the Solar Keymark report (report-21236476) regarding mechanical loads:
