Recommended Applications

This cable is specifically engineered for high-demand solar environments. For example, it is commonly used in the following installations:

Utility-scale solar farms and power plants

Commercial and industrial rooftop PV systems

Ground-mount solar arrays with long DC feeder runs

Connections between arrays, combiner boxes, and inverters

Large-scale battery storage systems

Therefore, it is ideal for projects that require high current capacity and long-distance power transmission.

Why Choose 500 MCM Aluminum PV Wire?

When selecting cable for large solar projects, both cost and performance are critical factors. For this reason, the 500 MCM aluminum conductor is widely specified by professional installers across the United States.

In addition, it offers several technical advantages:

Lower cost compared to copper — significant savings on large solar projects

High conductivity aluminum alloy — reduced voltage drop over long distances

UL4703 certified — meets NEC Article 690 photovoltaic system requirements

Extremely durable — resistant to UV, moisture, ozone, and abrasion

Rated for direct burial — therefore, additional conduit may not be required

Made in USA — trusted by solar professionals nationwide

Performance & Durability

Because solar installations operate in extreme outdoor environments, cable durability is essential. For this reason, the XLPE insulation used in this wire is engineered to resist UV radiation, ozone exposure, moisture, and mechanical abrasion.

Consequently, the cable maintains stable electrical performance throughout the expected lifespan of a solar system — typically 25 years or more.

Moreover, the wide −40°C to +90°C temperature rating ensures reliable operation in both cold northern climates and hot desert environments. Therefore, this cable performs consistently across all U.S. regions.

Frequently Asked Questions

Is this wire suitable for direct burial?

Yes. In fact, the 500 MCM Aluminum PV Wire UL4703 is rated for direct burial installation, as well as conduit and free-air applications, according to NEC guidelines.

What is the ampacity of 500 MCM aluminum PV wire?

Typically, 500 MCM aluminum conductor has an ampacity of approximately 430 amps at 90°C in free air. However, you should consult NEC Table 310.15 for conduit derating factors based on your specific installation conditions.

Can aluminum PV wire be used for residential solar?

Yes. However, 500 MCM is usually specified for commercial or utility-scale installations due to its large current capacity. For smaller residential systems, copper PV wire in 6 AWG, 8 AWG, 10 AWG, or 12 AWG is typically more appropriate.

Does this cable meet NEC requirements?

Yes. Since it carries a UL4703 listing, this cable fully complies with NEC Article 690 requirements for photovoltaic systems.
