What is the clamp size for a PV module?

For framed PV module, the clamp must overlap the module frame at least 8 mm (0.32 inch) but no more than 11 mm (0.43 inch). The cross section of clamp can be adjusted if the module is securely fastened. For frameless PV module, the clamp must overlap the module frame at maximum 15 mm (0.59 inch).

Where should clamps be connected to the PV module?

When the mechanical load pressure is ±2400Pa, Clamps should be connected to the module between 400 and 500mm from the edge of the module. This distance is from the module edge to the middle of the clamp. *NOTE: We need two or three support rails below the PV module to make sure the module have a good mechanical load performance.

Which materials should be used to install photovoltaic modules?

JA Solar recommends that when installing modules at the seaside, stainless steel or aluminum materials should be used to contact the photovoltaic modules, and the installation parts should be well protected from corrosion. The tilt angle of the modules is measured between the surface of the modules and a horizontal ground surface.

Is a Trina Solar PV module ul1703 compliant?

The fire rating of a Trina Solar PV module is valid only when mounted in the manner specified in the mechanical mounting instructions of this installation manual. The module is considered to be in compliance with UL1703 only when the module is mounted in the manner specified by the mounting instructions below.

How to install Trina Solar module with frameless clamps?

*NOTE: Please consult with a Trina Solar engineer before installing with the frameless clamps. Clamps should be connected to the module between 300 and 400 mm from the edge of the module. This distance is from the module edge to the middle of the clamp. *NOTE: Need two support rails below the PV module to make sure the Mechanical load.

How many clamps do I need to fix a module?

Use at minimum 4 clamps to fix modules on 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.
