TEMCo 10 AWG Solar Cable 70 ft Red - Made in USA, Durable PV Wire

In this review of the TEMCo 10 AWG solar cable, the bottom line is simple: this is a straightforward, American-made PV wire for installers and DIYers who need reliable conductivity and outdoor durability. The biggest reason to buy is the 19-strand pure copper conductor combined with XLPE insulation that meets UL 4703, which makes it suitable for long-term photovoltaic use, direct burial, or conduit runs. The wire balances rigidity and semi-flexible handling, so it performs well where consistent electrical performance and resistance to UV, heat, and abrasion matter most.

Key Features

• Made in the USA: Manufactured domestically to consistent quality standards so buyers get a reliably produced PV cable.
• 19-Strand Pure Copper: Solid copper conductors (no CCA) offer dependable conductivity and long-term corrosion resistance for solar arrays.
• 600 VDC, 50 amps: Electrical ratings suitable for many residential and small commercial PV circuits and combiner runs.
• XLPE Insulation: Cross-linked polyethylene resists heat, UV, chemicals, and abrasion for outdoor and direct burial installations.
• Wide Temperature Range: Rated from -40C to 90C so it can be used in diverse climates without compromising performance.
• Physical Size: Nominal outside diameter of 0.230 in and roughly 17.54 ft per pound for straightforward planning and handling on site.

Who It's For

The TEMCo 10 AWG PV cable is best for homeowners installing rooftop or ground-mounted solar who want an American-made, UL 4703 certified wire that can be buried or run in conduit. It suits small installers and hobbyists who need a dependable 600 VDC cable with pure copper conductors and robust insulation.

This wire is less ideal for projects that require extreme flexibility for tight, intricate routing-some users note it is semi-flexible rather than highly pliable. If you need ultra-flexible cable for connector-heavy runs in very tight spaces, consider a cable specifically marketed for high flex rather than a standard PV wire.

Pros & Cons

Pros

• Pure 19-strand copper conductor provides reliable conductivity and longevity.
• XLPE insulation and UL 4703 certification make it appropriate for direct burial and outdoor use.
• Made in the USA, which many buyers regard as a mark of consistent manufacturing quality and value.
• Electrical ratings (600 VDC, 50 amps) cover common residential PV needs.

Cons

• Not exceptionally flexible; customers report moderate stiffness and some coiling tangles when uncoiling longer lengths.
• Thickness and tight coil can make handling awkward during initial installation for a single person.

It represents good value for buyers who prioritize long-term outdoor performance and direct burial capability, though installers who need maximum flexibility should plan accordingly.

Frequently Asked Questions

Is this wire suitable for underground burial?
Yes. The XLPE insulation and UL 4703 compliance make it direct burial rated without additional conduit in most typical installations.

Can this cable handle typical home solar currents?
Yes. The 10 AWG conductor is rated for 50 amps and 600 VDC, which is suitable for many residential PV circuits and combiner wiring.

How flexible is the cable for routing around panels?
It is semi-flexible due to the 19-strand copper construction; it works well for standard routing but is not as pliable as specialized high-flex cable.
