TEMCo 10 AWG Solar Cable 90 ft - Made in USA PV Wire

In this review of the TEMCo 10 AWG PV solar cable, the bottom line is straightforward: this is a practical, American-made run of solar wire best suited for installers and DIYers who need a reliable, direct-burial rated conductor without paying for exotic features. The reviewer found the 19-strand pure copper construction and UL 4703 XLPE insulation to be the primary reasons to buy, since those details directly affect conductivity, longevity, and outdoor durability in photovoltaic systems.

Key Features

• Made in the USA: Manufactured domestically to consistent quality standards, which gives confidence in traceability and production control.
• 19-Strand Pure Copper: The multi-strand bare copper conductor offers reliable conductivity and enough flexibility for routing across panels and combiner boxes.
• 600 VDC, 50 amp rating: Electrical ratings cover common residential and small commercial PV runs without up-sizing the circuit.
• XLPE Insulation: Cross-linked polyethylene resists heat, UV, chemicals, and abrasion for long-term outdoor service.
• Direct Burial Rated: Intended for above-ground, conduit, or underground installation without additional protective sleeving when installed per code.
• Physical size and handling: Nominal outside diameter and strand count make the cable semi-flexible for typical site installations.

Who It's For

The TEMCo 10 AWG solar cable is best for solar installers, electricians, and DIY homeowners wiring PV arrays who want a straightforward, UL 4703-certified cable made in the USA. It fits well for runs where 600 VDC and up to 50 amps are appropriate and where direct burial capability is desirable.

Those who need extreme flexibility for tight bends, ultra-lightweight conductors, or thinner insulation for very compact spaces should look elsewhere. Also, projects requiring larger ampacity or higher voltage ratings will need a different gauge or cable type.

Pros & Cons

Pros

• Pure 19-strand copper provides dependable conductivity and durability for PV systems.
• XLPE insulation and UL 4703 certification mean the cable is built to withstand outdoor exposure.
• Direct burial rating adds installation flexibility for surface, conduit, or underground use.

Cons

• The cable is semi-flexible rather than highly pliable, and some users report stiffness and coiling challenges during unspooling.

Specifications

Our Verdict

For most residential and light commercial PV installs, this TEMCo 10 AWG solar cable is a practical value: it pairs pure copper conductors with robust XLPE insulation and UL 4703 certification, plus direct burial capability, making it a solid choice for dependable outdoor service. Buy it if you need a straightforward, American-made PV conductor and accept modest stiffness during handling.

Frequently Asked Questions

Is this cable suitable for underground runs?
Yes, the cable is direct burial rated and can be used underground when installed according to local electrical code.

Can this wire handle typical residential solar strings?
Yes, it is rated 600 VDC and 50 amps, which covers many residential PV string and combiner applications.

How flexible is the cable for routing?
The 19-strand design is semi-flexible; it handles common routing but is not as pliable as finer-strand or specialized flexible cables.
