Mounting Methods
• Select the appropriate orientation to maximize sunlight exposure.
• In order to prevent water from entering the junction box, which could present a safety hazard, module should not
• Clearance between the solar module frames and structures such as roofs or ground is required to prevent wiring
damage and to allow air to circulate behind the solar module. The recommended standoff height is a minimum
of 100 mm.
• The solar module is only IEC listed for use when its factory frame is fully intact.
• Do not remove or alter the solar module frame.
• Creating additional mounting holes may damage the solar module and reduce the strength of the frame.
• A 6 mm gap between module frames should be allowed to avoid tension from thermal expansion.
• The solar module may be mounted using the following methods: (*Torque: 8~12Nm )
• When installing modules in heavy snow areas, special care should be taken to install the modules in a manner
Mounting by using frame bolts holes
• Secure the solar module to the structure using the factory mounting holes.
• The module may be fastened to a support using both the outer and inner
bolt holes of the frame.
• Each module should be securely fastened at a minimum 4 points on
two opposite sides.
• Tighten the bolt securely using this combination. Place spring washer
Mounting by using clip or clamps
• The module may be fastened to a support using clips or clamps on
both the long edge and the short edge of the modules.
‘Mechanical Installation Scene’ (Refer Appendix.).
• The module frame must overlap more than 15 mm.
Clamp system requirements
• Clamp width is more than 30mm, depth is more than 10 mm.
Clamp height compliant with a frame height.
• The clamp should not be touched with the module’s glass.
• Use corrosion resistant material clamps and hardware.
• Use appropriate bolted connections as per clamp manufacturer’s
instructions.
