What is a power rail PV module mounting system?

The PV module mounting system engineered to reduce installation costs and provide maximum strength for parallel-to-roof, tilt up, or open structure mounting applications. The POWER RAIL mounting system is designed with the professional PV solar installer in mind.

How to connect a module and a bracket system?

Module and bracket system connection can be realized by mounting holes, clamps or embedded systems. Installation shall follow the demonstration and suggestions below. If installation mode is different, please consult LONGi and obtain approval. Otherwise, modules may be damaged and quality warranty will become invalid.

Can a racking system be used to ground a PV module?

This racking system may be used to ground and/or mount a PV module complying with UL 1703 only when the specic module has been evaluated for grounding and/or mounting in compliance with the included instructions. The system is a non-separately derived system.

How to mount a bifacial PV module?

For frameless PV module, the clamp must overlap the module frame at maximum 15 mm (0.59 inch). The applied value of torque should refer to mechanical design standard and the bolt type customer is using, for example: M8: 14-18 N•m. Bifacial modules can be mounted by bolts or clamps. The mounting method and maximum test load are shown as follow.

How do I connect a solar stack module to a pedestal?

Modules should be bonded to the Solar Stack pedestals with the manufacturer approved middle/end clamps. Grounding hardware (as a part of the module clamps) forms secure electrical bonds with both the module and the pedestal, resulting in many parallel grounding paths throughout the system.

Are solar stack roof mounting systems ul 2703 listed?

Solar Stack Roof mounting systems are UL 2703 listed. Standard for safety UL/ANSI 2703, Mounting Systems, Mounting devices, Clamping/Retention Devices and Ground lugs for use with PV modules. Solar Stack systems have been evaluated for module-to-system bonding and mechanical load to the requirements of UL/ANSI 2703.
