"An advanced, high-voltage single-conductor solution engineered for the critical interconnection wiring of both grounded and ungrounded solar power systems. Built to withstand high-capacity energy generation, this 1 AWG aluminum PV wire provides a lighter, exceptionally cost-effective alternative to copper for commercial utility arrays, field distribution blocks, and renewable energy grids."
Outdoor solar setups require components that stand up to the elements. This 1 AWG solar pv cable delivers dependable service by surrounding a high-grade, 18-strand compact AA-8000 aluminum core with a rugged, UL-listed Sunlight Resistant (SUN RES) cross-linked polyethylene (XLPE) insulating barrier. The thick insulation shield is specifically designed to brave severe outdoor exposure, resisting intense solar UV rays, seasonal frost, shifting soil conditions, and common field chemicals without snapping or wearing down.
High-Capacity 2000V Threshold: Engineered safely for systems running up to 2000 Volts to easily accommodate modern, high-output commercial solar configurations.
Code-Approved Tray Placement: Meets all requirements under NEC Article 690.31(C)(2) for open, unprotected routing inside exterior cable trays.
Direct Burial & Outdoor Utility: Waterproof and UV-blocking XLPE jacket allows for direct underground burial trenches and long-term open-air exposure.
Extreme Weather Performance: Engineered to stay structurally stable and completely flexible in temperatures from -40°C up to +90°C

Yes. Under National Electrical Code (NEC) guidelines, aluminum wire is fully code-compliant and approved for solar PV source and output circuits. While smaller residential setups traditionally utilize copper for micro-inverter runs, commercial, utility-scale, and larger ground-mount residential arrays heavily rely on heavy-gauge aluminum wire to drastically reduce upfront material costs without sacrificing system power or performance.
Aluminum has a slightly lower electrical conductivity than copper, meaning you typically need to scale up the wire size by one or two gauges to carry the exact same electrical load (ampacity). For example, if a solar blueprint calls for a 6 AWG copper feeder run, an aluminum alternative will generally require a 4 AWG size. Even with the slightly larger wire gauge and conduit size requirements, switching to aluminum frequently reduces the raw material cable cost by 50% to 60% on long structural runs.
Yes. Premium aluminum solar wires are dual-rated as Type USE-2 (Underground Service Entrance) and RHW-2. Outfitted with a heavy-duty, chemically cross-linked polyethylene (XLPE) outer insulation jacket, the cable is explicitly engineered to handle continuous moisture, direct soil contact, and harsh underground chemical environments. It can be laid straight into clean earth trenches or slid through protective PVC conduit per standard NEC burial depth guidelines.
To guarantee a flawless, corrosion-free lifespan, aluminum terminations must be handled using standard professional trade practice:
Yes. The rugged XLPE insulation layer features advanced ultraviolet stabilizers. It carries an official Sunlight Resistant (Sun-Res) certification stamped directly onto the cable jacket print legend, allowing it to be safely strapped to open racking networks, exposed metal frames, or vertical poles without cracking, degrading, or drying out over decades of direct solar exposure.
Wire America fulfills and ships our complete inventory of Copper and Aluminum Solar PV Wire directly from our strategically located national distribution hubs across the United States. We prioritize shipping pv cables from the warehouse nearest to your job site to keep transit times minimal. Orders typically arrive within 2-4 business days. Expedited shipping options are available at checkout for time-sensitive contractor deadlines.
UL 4703 is the definitive industry standard governing Photovoltaic (PV) Wire. It covers three distinct voltage classes — 600V, 1000V, and 2000V—making it compatible with everything from residential rooftop systems to massive utility-scale arrays. Unlike standard building wire, cables certified under UL 4703 feature advanced cross-linked polyethylene (XLPE) insulation specifically engineered to endure extreme outdoor weathering. This standard mandates strict testing for superior UV resistance (Sun-Res), optional direct burial routing, moisture defenses, and a wide thermal range (typically-40°C to 90°C wet/dry).
