Photovoltaic (PV) Wire

PV wire is a single conductor, sunlight-resistant wire rated 90ºC wet or dry for interconnection wiring of grounded and ungrounded photovoltaic power systems

The National Electrical Code (NEC) rates the cables in the United States, while the Canadian Electric Code (CEC) rates them in Canada. PV wire conductors are made of copper or aluminum.

Applications of PV Wire

Connecting Solar Panels to a Combiner Box

The most common application of PV wire is connecting solar panels. This involves running a 12 AWG to 8 AWG wire from the combiner box to the ground in a short run (less than 100 feet).

Open Air Installation

This involves tying the PV wire directly to a rack. It’s a fast and cost-effective way to install solar panels, as there is no need for a trench or foundation.

Connecting Combiner Boxes to the Inverter

PV wire can also connect combiner boxes to inverters. These wires are usually power-sized aluminum cables (4/0 AWG to 1000 kcmil) that extend for hundreds of feet. 

Direct Burial (Trench) Installation

Direct burial or trench installation can accommodate many circuits in a single common trench. This cost-effective method allows for native backfill to support the foundation.

Solar Cables and Accessories

At American Wire Group, we specialize in cables, wires, and accessories for renewable energy applications and other utilities. Learn more about our products below.

Communication Cables

We offer fiber optic cables in single-mode and multimode varieties. These RS485 twisted copper wires are protected by a single jacket, double jacket, single armor/single jacket, double armor/double jacket, or fiber in duct option. It can be used as optical ground wire (OPGW), with OPGW hardware included.

Grounding Wires

Electrical wires ensure circuits run smoothly by safely discharging excess electricity. Our bare copper and copper-clad steel wires are designed to achieve this goal.

Medium Voltage Power Cables

Our medium voltage power cables range from 5 kV to 46 kV and come with an LLDPE or XLPE jacket. We offer copper tape, concentric neutral wires, or flat straps. Insulation options include:

  • TR-XLPE insulation, MV-90 or MV-105
  • EPR insulation, MV-90 or MV-105

Transmission & Distribtuion Wire & Cable

We provide overhead bare or covered transmission wires such as ACSR or AAAC. 

Wire & Cable System Accessories

We offer the following wire and cable system accessories:

  • Elbows
  • Elbow arresters
  • Sectionalizing cabinets
  • Splices
  • Terminations
