6.1 MOUNTING METHOD: BOLTING
The mechanical load test with these mounting methods
were performed according to IEC 61215.
Modules should be bolted to supporting structures through
the mounting holes in the rear frame flanges only.
Each module must be securely fastened at a minimum of 4
points on two opposite sides.
Suitable bolt length should be chosen
based on actual module frame height. For
double glass module with 30 mm frame
height, our recommended maximum bolt length is 20 mm
in order to properly insert the bolts through the mounting
hole. The system designer is responsible to check that the
racking supplier specified bolt length complies with above
requirement and will not affect installation.
In areas with heavy wind loads, additional mounting points
should be used. The system designer and the installer are
responsible for correctly calculating the loads and ensuring
that the supporting structure meets all the applicable
requirements.
Mounting method: Bolting
Modules should be bolted at the following hole locations
depending on the configuration and loads, which is shown
in table 3.
