Photovoltaic Cable & Accessories for Solar Installations — Complete UL4703 Product Range

Photovoltaic Cable LLC supplies the complete range of photovoltaic cable and accessories for solar installations of every scale — from residential rooftop systems to utility-scale ground-mount arrays. Specifically, our catalog covers copper PV wire in 6, 8, 10, and 12 AWG at 2000V and 600V, 500 MCM aluminum photovoltaic cable, 1500V solar panel connectors, crimping tools, and DG flat cable for microinverter systems. As a result, solar contractors, EPCs, and distributors across the USA can source every conductor and connection point from a single, in-stock supplier that ships the same day.

Copper Photovoltaic Cable 2000V — The Core of Every Solar String

Our copper photovoltaic cable for solar installations is available in 6, 8, 10, and 12 AWG, rated to 2000 volts DC and UL4703-listed. Furthermore, each gauge ships in 500, 1000, 2500, and 5000-foot reels in black and red, giving installers the exact quantity needed for any project size. The 19-strand flexible copper conductor is paired with XLPE insulation that resists UV, moisture, and ozone — making this photovoltaic cable and accessories combination suitable for direct burial, conduit, and exposed rooftop installations across all US climate zones.

Consequently, our 2000V copper photovoltaic cable is fully compatible with modern 1500V string inverter platforms and meets NEC Article 690 requirements for solar installations nationwide.

Copper Photovoltaic Cable 600V — For Residential and Legacy Systems

In addition, we stock 10 AWG photovoltaic cable rated to 600V UL4703 for residential systems and legacy inverter platforms. This lower-voltage-rated cable is an essential accessory for solar installations using older inverter technology or smaller string configurations, and it ships from the same fulfillment centers with the same same-day availability.

Aluminum Photovoltaic Cable 2kV — For Large-Scale Solar Installations

For utility and commercial solar installations where feeder runs exceed several hundred feet, our 500 MCM aluminum photovoltaic cable 2kV UL4703 is the cost-effective solution. Since aluminum conductors deliver approximately 61% of copper's conductivity at a fraction of the cost, they are the preferred photovoltaic cable choice for inter-array home runs and combiner-to-inverter connections on projects above 500 kW. Moreover, this photovoltaic cable is RoHS-compliant and rated for direct burial — making it a complete, code-ready accessory for utility-scale solar installations.

Solar Panel Connectors — Essential Accessories for Solar Installations

No photovoltaic cable system is complete without reliable, weatherproof connections at every module junction. Therefore, we stock 1500V solar panel connectors for 8, 10, and 12 AWG PV wire — a critical accessory for any solar installation. Sold in 50-pair bags, these connectors feature an IP67 weatherproof rating, UV-resistant thermoplastic housing, and a snap-lock mechanism that prevents accidental disconnection. In particular, we also carry matching crimping tools for 6, 8, 10, and 12 AWG, so contractors can source photovoltaic cable and all accessories for their solar installation from a single order.

DG Cable — Microinverter Accessory for Solar Installations

For distributed generation systems, we offer 12/2 DG flat cable (THHN/PVC 600V) — a specialized photovoltaic accessory for solar installations using microinverters. This cable handles the AC output wiring from microinverter units to the junction box and is NEC-compliant for exposed rooftop runs.
