Solar DC cable · Georgia
We buy PV wire and solar DC cable in Georgia
PV wire, dual-rated USE-2/RHW-2 DC feeder and tracker harness from arrays that were resized, repowered or never finished. Reviewed on voltage rating, sunlight resistance, size and whether the cable has been flexed in service.

- USE-2 and RHW-2
- Sunlight resistant
01Overview
What this page covers
Solar cable is not a single product. PV wire made to UL 4703 runs from a module lead to a string combiner or to a harness; USE-2 and RHW-2 dual-rated cable does the DC home runs; tray-rated cable carries DC inside a building; and medium voltage feeder takes the AC side from the inverter transformer. Each has its own voltage class, and they do not substitute for one another.
Most of what reaches a buying desk comes from a project that changed shape. An array is value-engineered down and the string cable ordered for the original layout is surplus. A tracker fleet is repowered and the harnesses come off. A rooftop job is completed with part reels left in the trailer. A project is cancelled before the first module is set.
The distinguishing question for PV cable is not what it is made of but what it has already been through. Cable that has spent years flexing on a tracker is a different asset from cable that never left the wrapper, even when both carry the same print.
02Specification
What the print and tag tell us
- Types
- PV wire per UL 4703, USE-2, RHW-2, and dual-rated USE-2/RHW-2
- Voltage
- 1 kV standard; 2 kV for 1,500 V systems
- Sizes
- 10 AWG through 500 kcmil; 10 and 12 AWG dominate string work
- Insulation
- XLPE and EPR, sunlight resistant, 90°C wet rated
- Construction
- Single conductor, and paired or multi-conductor harness assemblies
- Reels
- 500 ft and 1,000 ft reels; coils on small string sizes
- Condition
- New surplus, part reel, removed from tracker, UV aged
The voltage rating is printed with the type. A 1 kV reel cannot serve a 1,500 V array, so read the print.
03Solar cable we buy
Solar cable we buy
PV wire, 1 kV and 2 kV
Single-conductor cable with a thick cross-linked jacket built for continuous sunlight and wet rating. Reviewed on voltage class and jacket condition.
USE-2 and RHW-2 dual rated
Underground service cable that doubles as DC feeder. The dual rating is what makes it usable in a trench and at a module, and it is printed on the jacket.
Tracker harness and home runs
Paired and multi-conductor assemblies with molded or field-fitted connectors. Reviewed on conductor count and connector condition, and rarely reusable once the flex points have hardened.
DC tray and inverter cable
Tray-rated cable for interior DC runs and the larger feeder between inverter and transformer. Sizes and insulation are families used elsewhere, so the print matters more than the appearance.
04Evaluation
How a PV lot is reviewed
Voltage class and type come first, because they decide whether the cable can be used at all. A 1 kV PV wire will not serve a 1,500 V string, and a reel of THHN cannot be substituted into a DC run. The print settles both questions in a single photograph.
Service history is second. Cable that has run on a tracker for years has been flexed at the same points thousands of times, and the damage is internal and invisible until the conductor fails. Where a harness came off a working machine, say so. Where a reel was opened and half used, footage and jacket condition matter more than flex history.
Then condition of the jacket. Sunlight, heat and abrasion are the three things that end PV cable's life, and all three show on the surface as chalking, crazing or a flattened profile. Cable that has been coiled tight in the sun for a season takes a set that makes it hard to pull.
DC arrays are live whenever the sun is up. String cable is never disconnected, coiled or cut in daylight without the array isolated and the conductors proved dead at the combiner. PV connectors are not load-break devices.
05Seller terms
Before you sell: how it works
Four things a seller should be able to pin down before a truck is booked.
Verification
Footage is checked against the reel tag, the sequential marks on the jacket, the wrap count against the barrel, or a published weight per 1,000 ft — whichever the reel actually supports.
Payment
Payment method and timing are agreed in writing for the specific lot before anything is loaded or moved. No verbal number is treated as an agreement.
Paperwork
A bill of sale for the lot, and for utility material the owning utility’s release reference. Neither is optional and neither is created after the fact.
Freight
Collection is arranged as part of the terms. Say what can lift the reels and whether a 53-foot trailer can reach them, and the pickup is planned around that.
Sending a reel list and photographs costs nothing. A review is not a purchase, and nothing is bought, moved or scheduled until written lot terms are agreed for that material. Request a pickup when the lot is ready.
07Questions
Solar PV cable questions
Can PV wire be used for anything other than solar?
It is a 1 kV or 2 kV single conductor and can be used wherever that rating and sunlight resistance suit. It is not a substitute for building wire in a raceway.
Do you buy cable from a tracker that is being repowered?
Yes, with the service history stated. Harness that has been flexing in service is recovery material; unopened reels are inventory.
Is UV damage visible?
Usually. Chalking, a faded surface and fine crazing when the jacket is bent are the signs. A jacket that has gone stiff and takes a set is near the end of its life outdoors.
Do connectors and cable get reviewed together?
Separately. Cable is reviewed on footage and jacket; connectors are a hardware item with their own condition questions. A harness keeps both together.
Send the print, the voltage class and the footage
Type, voltage rating, size and remaining footage start the review. Say whether the cable is unopened, part used, or removed from a working array.
