TEMCo 10 AWG Solar Cable 125 ft Black - Made in USA

In this review of the TEMCo 10 AWG PV solar cable, the bottom line is straightforward: this is a dependable, American-made run of solar wire for DIY installers and small commercial PV arrays who need a robust conductor rated for outdoor and direct-burial use. The biggest reason to buy is its 19-strand pure copper core and XLPE insulation that together deliver reliable conductivity and long-term weather resistance, making it a practical choice when longevity and safety matter more than extreme flexibility.

Key Features

• Made in the USA: Manufactured domestically to consistent quality standards so buyers get traceable production and material control.
• 19-strand pure copper: The stranded bare copper conductor provides solid conductivity and semi-flexible handling for easier routing around panels and conduit.
• 600 VDC and 50 A rating: Suitable for typical PV string circuits and many small system configurations where 600 VDC ratings are required.
• XLPE insulation: Cross-linked polyethylene resists heat, UV, chemicals and abrasion for long-term outdoor exposure.
• Direct burial rated: Can be installed above ground, in conduit or underground without additional jacketing in many installations.
• Physical gauge and size: Nominal outside diameter and weight make it manageable on reels and practical for runs where space is limited.

Who It's For

The TEMCo 10 AWG solar cable is well suited for homeowners, solar installers, and hobbyists wiring small to medium PV systems who prioritize a pure copper conductor and a UL 4703 compliant product. Its direct burial rating and -40C to 90C temperature range make it a good match for outdoor arrays, off-grid projects, and connectors that require a robust, weather-resistant wire.

It is less appropriate for projects that require ultra-flexible wire for very tight bends or for installers who need preterminated leads; the semi-flexible 19-strand construction is easier to handle than solid wire but not as limp as some specialized flexible cables.

Pros & Cons

Pros

• Pure copper conductor gives reliable conductivity and long-term performance with connectors and PV equipment.
• XLPE insulation and UL 4703 compliance provide confidence for outdoor and direct-burial installations.
• Made in the USA and practical size make it a good value for quality-conscious buyers.

Cons

• Not super flexible; installers used to very soft solar cables may find it stiffer to route.
• The tightly coiled cable can tangle if care is not taken when unspooling on long runs.

Specifications

Our Verdict

The TEMCo 10 AWG solar cable is a sensible choice for most residential and small commercial PV installations where a durable, UL 4703-rated, direct-burial wire is required. Its pure copper conductor and XLPE insulation deliver lasting performance and good value for installers who want American-made components, though those needing maximum flexibility should consider alternative cable types.

Frequently Asked Questions

Can this cable be buried directly in the ground?
Yes. The wire is direct burial rated and can be run underground without additional protection where local code allows.

Is this cable compatible with standard MC4 solar connectors?
Yes. The 10 AWG pure copper conductor works with common PV connectors and readily accepts crimp or compression terminations used in solar arrays.

How flexible is the cable for routing on rooftops?
The 19-strand construction is semi-flexible and easier to handle than solid wire, but it is not as limp as specialty flexible cables, so plan for slightly larger bend radii.
