Mounting With Bolts - boviet SOLAR GAMMA Series Installation And Maintenance Manual

When the climate of the project site is normal, we recommend using 4-hole mounting (M8 nut). The yellow 4-hole
mounting (M8 nut), or blue 4-hole mounting (M8 nut) can be used.
When the climate of the project site reaches severe conditions (2400Pa wind load and 5400Pa snow load), the blue or
yellow 4-hole mounting (M8 nut) need to be used, in addition to the middle red auxiliary mounting hole (M6 nut).
In any case clamps should not contact the glass or deform the assembly frame.
The surface of the clamps touching the frame should be flat and smooth; otherwise, the frame and components may be
damaged. For better performance be sure to avoid shading from module clamps.
The drainage holes are not blocked by clamps.
The module frame is not modified under any circumstances as this will not void the warranty.

5.2 MOUNTING WITH BOLTS

There are four 4 (9*14mm) and six (7*10mm size) mounting holes at each panel to mount the modules on a supporting
structure. The module frame must be installed on the mounting rail using M8 corrosion-proof screws together with
spring washers and flat washers in four (4) symmetrical locations on the module.
The applied torque should be approximately 17-23 N*m. The applied torque value should be big enough to fix the
modules securely. For special support systems or special installation requirements, please confirm torque value with the
specific support supplier. Please find detailed mounting information in Figure 4.
When using six (6) mounting holes, the middle two (2) mounting holes are the auxiliary mounting holes which use M6
bolts. The applied torque should be approximately 7-11 N*m for these bolts. PV module mounting information when
installed with screw fitting method as shown in Figure 4.
