About What are the methods for pulling the wires of photovoltaic brackets
The Trunk Method. A “trunk” is a wire management tray or conduit where jumper wires are bundled together and routed to the homerun. The trunk method requires preplanning where the strings’ conductor ends will attach to the jumpers and where the wire management trays or conduit will go.

Key feature: Quick, code-compliant utility-grade cable separation. Solar Snake Max is Snake Tray’s new patented cable management system for high-voltage, utility-grade installations. The easily snapped together elements allow for code-compliant cable separation that can cut construction cycle times in half.
How to attach cables to photovoltaic solar modules the right way. As global market leader in cable management, HellermannTyton offers solutions that help prevent photovoltaic panel downtimes. With solutions that guarantee a long lifetime, some of which have been developed specifically for the solar sector.
Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.
Use (metal) raceways, conduits or other methods to combine the wires but separate strings from different inverters in separate conduits or raceways with a minimum distance of 50cm / 20inch in order to mitigate crosstalk.

6 FAQs about [What are the methods for pulling the wires of photovoltaic brackets ]
Which wiring methods are applicable for photovoltaic (PV) systems?
In general, the wiring methods presented throughout the Code are applicable for photovoltaic (PV) systems. More specifically, Part IV of Art. 690 is titled “Wiring Methods,” which helps us establish the fundamental requirements for conductor selection and installation for PV systems.
What should be considered when wiring a solar PV system?
When wiring a solar PV system, it is essential to consider important requirements for voltage, ampacity, voltage drop, and circuit length. This publication explores these considerations and emphasizes the importance of safely sizing wires and overcurrent protection devices for proper system design.
How to wire solar panels together?
Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.
What type of cable do I need for a solar array?
For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard. For ground-mounted PV installations requiring underground installations, you need an Underground Service Entrance (USE-2) cable. Are you using microinverters or string inverters for your array?
Why is cable management important in solar PV arrays?
Cable Management in Solar PV Arrays: Cable management is one of the most important aspects of the safety and longevity of nearly every photovoltaic (PV) system. This is primarily due to the extensive use of exposed cables used in the PV array.
Which cable is used in PV array?
USE-2 cable is commonly used in PV array and is very similar to the PV Wire also used in many PV arrays which is why it is mentioned in the same section in 690.31(C)(1) in the NEC. Article 338.10(B)(4) refers the installer on to Article 334.30 for support methods.
