500 MCM Aluminum PV Wire 2kV UL4703 | Utility-Scale Solar Cable

500 MCM Aluminum PV Wire 2kV UL4703 — Made in Mexico | In Stock | Ships Same Day

Photovoltaic Cable LLC supplies UL4703-certified 500 MCM Aluminum PV Wire rated at 2kV, engineered for utility-scale solar farms, commercial rooftop systems, and large ground-mount installations where aluminum conductors provide a cost-effective alternative to copper for long-distance feeder runs. Available in Black and Red. Manufactured in Mexico to UL4703 standards. In stock and ships same day from our three U.S. fulfillment centers.

Why choose aluminum PV wire for large projects

For main feeder runs exceeding 500 ft and currents above 200A, aluminum PV wire delivers significant cost savings per foot compared to copper — without sacrificing electrical performance at the conductor sizes used in utility-scale systems. The 500 MCM size provides high conductivity and low resistance, making it the preferred specification for solar-to-inverter and inverter-to-grid transmission runs in large commercial and utility projects.

For shorter runs and string wiring, our copper PV wire collection remains the standard choice.

Frequently asked questions

When should I use aluminum instead of copper PV wire?
Aluminum is cost-effective for main feeder runs exceeding 500 ft and currents above 200A. For string wiring, combiner box connections, and runs under 500 ft, copper remains the preferred choice. Use our Voltage Loss Calculator or contact our team for a project-specific recommendation.

Is this wire available in other MCM sizes?
Currently available in 500 MCM. Contact our sales team at +1 305 842-6291 to discuss availability of other sizes for your project.

Is this wire rated for direct burial?
Yes. UL4703-listed PV wire is rated for direct burial, conduit, and free-air installation per NEC Article 690 guidelines.

Do you offer volume pricing for utility-scale projects?
Yes. Contact our sales team at +1 305 842-6291 or sales@photovoltaiccable.com for project-specific pricing.
