2.3 Mechanical Installation Introduction

Jinko Frameless Dual glass modules usually can be mounted by the clamps.
Jinko Dual glass modules of frame usually can be mounted by the clamps and bolts.
According to IEC61215 for a maximum positive design loading of below 3600Pa, and negative
design loading 1600Pa, with 1.5 times safety factor.

Be sure to avoid shadowing effects from the module clamps. When choosing this type of clamp-
mounting method, please be sure to use at least six clamps on each modules, and three clamps
should be attached on each long side of the module. Depending on the local wind and snow
loads, if excessive pressure load is expected, additional clamps or support would be required to
ensure the module can bear the load. The applied torque should be large enough to fix it steadily
(about 16-20 N▪m) .For safety, you'd better follow the clamps manufacture's recommendation.
Please find detailed mounting information in the below illustration, and we suggest the clamps
are mounted between J and K, as shown below.
