Photovoltaic bracket installation specifications and dimensions table

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.

What is the maximum voltage a photovoltaic module can run?

For roof use, the maximum system voltage must not exceed 600V according to National Electrical Code. Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions.

How far should a clamp be connected to a PV module?

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. *Note: The above-described distance is from the module edge to the middle of the clamp.

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.

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.

Do I need to meter a photovoltaic system?

It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.
