When using LONGi 30mm (30H) height frame module, it is recommended to select L ≤ 20mm length
fasteners. (If there is a special model, consult LONGi customer service);
5.2.2 Clamp Mounting
The module can be mounted by a dedicated clamp, as shown in Figure 5.
Under no circumstances should the clamp touch the glass or deform the frame. The interface of the clamp to the front of
the frame must be smooth and flat to prevent frame or other components from being damaged.
Make sure no shadowing effect of the fixture.
The drain hole cannot be blocked by the fixture.
For framed PV module
，
the clamp must maintain an overlap of 8-11 mm with the frame of the module (you can change
the cross section of the clamp if the module is securely installed). For frameless PV module
，
the clamp must maintain an
overlap of 15 mm at maximum with the module.
