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 four clamps on each
module, and two 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.
