6 FAQs about [Photovoltaic panel clamp bolt torque]

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.

What size bolt & nut do I need for a clamp?

Please note that all dimensions below are in mm units. Trina suggests using M8 bolts to fix the clamp. The torque for M8 screw is 16-20 N*M. When choosing the bolts and nuts for the clamp, please note your racing’s dimensions first. Trina suggests using M8 bolts to fix the clamp. The torque for M8 screw is 16-20 N*M.

How to install Trina Solar module with frameless clamps?

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.

Which Racking clamps should I use for Trina Solar racking?

For C structure steel type 1 racking, due to the amount of space inside the racking section, many choices are available including T-shape nuts. 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.

What is the tilt angle of a PV module?

ilt Angle SelectionThe tilt angle of the PV module is measured between the surface of the PV module and a horizontal ground surface (Figure 1). The PV module generates maximum output power when it fac
