B. Mounting with Clamps
Trina Solar has tested its modules with a number of clamps from different manufacturers,
mounting bolt of at least M8. The length of clamp ≥40mm (1.57in) , thickness≥ 3mm(0.12in).
The clamp must overlap the module frame by at least 7mm (0.28in) but no more than 11mm
(0.43 in).
Use at minimum 4 clamps to attach modules to the mounting rails.
Modules clamps should not come into contact with the front glass and must not deform the
frame.
Be sure to avoid shadowing effects from the module clamps.
The module frame is not to be modified under any circumstances.
When choosing this type of clamp-mounting method, use at least four clamps on each module,
two clamps should be attached on each long sides of the module (for portrait orientation).
Depending on local wind and snow loads, additional clamps may be required to ensure that
