Method A: Bolting; Method B: Clamping - Canadian Solar CS6P-PE Installation Manual

6.1 METHOD A: BOLTING
The mounting method has been qualified by Canadian Solar Inc., and the method bolting on the short‐side frame has
been certified by VDE, the method bolting on long‐side frame has been certified by both VDE and TUV Rheinland.
Modules should be bolted to support structures through mounting holes located in the frame's back flanges only. Do not
drill additional holes or modify the module frame. Doing so will void the warranty.
Each module must be securely fastened at a minimum of 4 points on two opposite sides, using the most inner mounting
holes. If additional wind loads are anticipated for this installation, additional mounting points should be used. System
designer and installer are responsible for load calculations and for proper design of support structure.
Modules should be bolted at the following hole locations depending on the configuration and load:

6.2 METHOD B: CLAMPING
The mounting method has been qualified by Canadian Solar Inc and certified by VDE.
Top or bottom clamping methods will vary and are dependent on the mounting structures. Follow mounting guidelines
recommended by the mounting system supplier.
Each module must be securely fastened at a minimum of 4 points on two opposite sides. The clamps should be
positioned according to the authorized position ranges defined in table 4. Install and tighten the module clamps to the
mounting rails using the torque stated by the mounting hardware manufacturer. System designer and installer are
responsible for load calculations and for proper design of support structure.

Use 4 standard mounting holes (long side)
Use 4 standard mounting holes (short side). An
additional support bar should be placed below
the module.

Canadian Solar Inc. warranty may be void in cases where improper clamps or unsuitable installation methods are found.
When installing inter‐modules or end type clamps, take measures so as:
1. Not to bend the module frame
2. Not to touch or cast shadow on the front glass
3. Not to damage the surface of the frame
4. To ensure the clamps overlap the module frame by at least 5 mm.
5. To ensure the clamps overlap length is at least 40 mm.
Clamp material should be anodized aluminum alloy. Floating type clamps
are not authorized.
Clamp positions are of crucial importance for the reliability of the installation, the clamp centerlines must only be
positioned within the ranges indicated in table 4, depending on the configuration and load.
For configurations where the mounting rails run parallel to the clamps installation side, precautions should be taken to
ensure the module frame (C‐shape) overlap the rail by 15mm or more.
Use 4 clamps on the long side, the allowed range
depends on the module type.

For CS5P and CS6P series, an additional support bar
should be placed below the module where download
force above 1600Pa is expected. Mounting rails
should run parallel to the short side frame.
