Bad module clamping means a module is not fastened well enough, or the clamp has damaged the module or its frame. It can start during production or installation and shows up during operation. Visual inspection is the listed way to find it. Replace any module that poses a safety risk or has the highest severity rating. To prevent it, use only clamps that suit both the module and the mounting structure, follow the manufacturer's mounting instructions, and check the local wind and snow loads. For non-standard mounting, such as on a facade, have the setup tested by an accredited laboratory, and inspect the system regularly.
