10 AWG Solar Cable 125 ft Red - Made in USA PV Wire

In this review the TEMCo 10 AWG PV solar cable is evaluated for homeowners and installers who need a reliable American-made run of photovoltaic wire. The bottom line: this 125 ft spool of 10 AWG wire delivers solid conductivity and outdoor durability thanks to its 19-strand pure copper conductor and XLPE insulation, making it a practical choice when you need a long length rated for 600 VDC and direct burial. It is a good fit for system wiring where code-compliant PV wire and durability in sun and soil matter more than ultra-flexibility.

Key Features

• Made in the USA: Manufactured domestically to consistent quality standards, which helps ensure traceability and reliable construction for solar installations.
• 19-Strand Pure Copper: The stranded bare copper conductor provides dependable electrical conductivity and semi-flexible handling for easier routing than solid wire.
• 600 VDC Rating: The wire is rated to 600 VDC and 50 amps, making it suitable for typical PV string and module interconnects.
• XLPE Insulation: Cross-linked polyethylene resists heat, UV, chemicals and abrasion so the cable performs well outdoors and in conduit or direct burial.
• Wide Temperature Range: Rated from -40C to 90C, the cable is suitable for harsh climates and sustained outdoor exposure.
• Direct Burial Rated: Can be installed above ground, in conduit or buried without additional protection when following code and installation best practices.

Who It's For

The TEMCo 10 AWG solar cable is best for DIY solar installers, contractors, and property owners wiring arrays who value American manufacture, a pure copper conductor, and a cable built to UL 4703 PV wire standards. It is particularly useful when a long, continuous run is needed and the installer prefers a semi-flexible stranded conductor that holds its shape during routing.

Those who need ultra-flexible tinned conductors for repeated movement or tight bending may want to choose a different product, and anyone requiring a different voltage or ampacity should select a cable matched to those system specs. Also consider how you will store and uncoil the tight spool, as some users report handling can be awkward initially.

Pros & Cons

Pros

• American-made construction and UL 4703 certification deliver confidence in quality and PV suitability.
• Pure copper 19-strand conductor offers strong conductivity and easier terminations compared with CCA alternatives.
• XLPE insulation and direct burial rating increase long-term durability for outdoor installations.
• Long spool length provides good value for larger runs and reduces the need for splices.

Cons

• Wire is described as semi-flexible; it is not highly pliable and can feel stiff during installation for tight bends.
• The spool can be tightly coiled and may tangle if not carefully unrolled, requiring patience when deploying long runs.
