Shirbly Solar Panel Wire - 50FT Black & 50FT Red Tinned Copper Wire, 10AWG (6mm²) PV Wire Solar Extension Cable for Outdoor Automotive RV Boat Marine Solar Panel- Black & Red (10AWG 50FT)

I use this to power my RV. Its 10 gauge so its plenty for solar setups.

TLDR; yes Id buy this again when I need more This is the same Kibor Cable with a red jacket that is sold under a different name/seller with a black jacket. This is not an issue just pointing it out. I acquired this wire to use on some low-voltage rewiring projects on a boat. So far, I have used ~24 in various run lengths matched to what was used from a similar roll of black wire. The price per foot is a little less than I found locally and is an overall good price on Amazon. The specs on the wire match the description, and additional details from the manufacturer can be found online. Tinning on the conductors appears to be consistent and reasonably well coated. Insulation seems decent and is not abraded any more than other wire as I am pilling through fiberglass panels and wall grommets. The wire is somewhat stiff, but it pulled with ease (no lube used) and did not kink.

Its well made and the thing I liked the most was the copper is tinned, it helps to stop corrosion.

I use these for my battery bank in my barn. They work gray and made no negative difference in my power flow (had old copper lines before that were deteriorating).

Nothing

We are installing an under floor electric heating system. It came with 12 gauge wire but the instructions said to size up to 10 gauge tinned copper wire for any runs more than 20 feet. So we got this wire for our two longest runs. It works great, seems like good quality. But the insulation is very stiff, which made for a bit of a challenge.

This is a great multi purpose wire. It is tinned and can be used in most situations. The outer insulation is very good. I recommend this wire.

This wire is multistranded, tinned, and reasonably flexible considering it is 10AWG. It has what appears to be durable insulation. Compared to similar wire from other sources, the price seems reasonable, but it’s always good to comparison shop as the market offerings can change so quickly. I generally purchase name brand marine-rated wire, but for the project I am using this wire for, in an enclosed protected area, it is working just fine.

Best Ive Found! High Quality at a great price.

Summary: When it comes to buying wire/cable, there are lots of variables, so doing some homework is warranted. Aside from the what size wire do I need, here are some other considerations: 1) pure vs. cladded wire, 2) jacket material (PVC, silicone), 3) single or dual (or more wires, 4) indoor/outdoor. Most of the wire I have reviewed has been used in extending a solar panel installation for optimal placement. General Observations: Stranded wire will always be more flexible than solid single conductor (such as house wiring). For most applications, having some flexibility is desirable for ease of installation. For power transmission, pure vs. cladded is the preferred option, but will cost more. For outdoor or direct bury applications, you will want to select a suitable jacket material. I have left silicone wire out in the sun for a month, and it has faded (which is why UV rated jackets are desired in those applications). RAKDSYMC Observations: This one does not specify the jacket material (likely PVC). This is a single insulated jacket, 10AWG wire. A 2x30 ft length for $40, so cost is $0.67/foot. The ends are not terminated. This one is lower cost than the other comparable offerings, but does not include any termination, so overall cost ends up being the same once you add connectors (I added MC4). This company has few wire options, therefore a non-specialty manufacturer. SHIRBLY Observations: This is a single wire offering, PVC insulated jacket, 10AWG wire. A 50 ft length for $28, so cost is $0.56/foot. The ends are not terminated. This one is lower cost than the other comparable offerings, but does not include any termination, so overall cost ends up being the same once you add connectors (I added MC4). This company has few wire options, therefore a non-specialty manufacturer. HAERKN Observations: This is a bonded pair of 10AWG, red/black, with a silicone jacket. Its a single 10ft length (20ft of single conductor), so cost is $0.85/foot. The ends are not terminated. The SHIRBLY below is the same cost, but includes four (4) MC4 connectors, about $4 value; and also includes a heat resistant sheath (value unknown). HAERKN has nine wire offerings (non-specialty). MATUGAJP Observations: This is a pair of 10AWG wires, inside another protective sheath; PVC jacket. Cost is $22 for 10ft length (20ft of single conductor), so cost is $1.10/foot. The 20ft offering is $0.78/foot. The ends are not terminated. This is ideal for PV/Solar applications which have the wire left outside to the weather, as it affords much better protection. MATUGAJP only has two other wire offerings (non-specialty). Recommendations: Here are some considerations when sizing the wire gauge for your application: 1) the thicker the wire (lower AWG number), the lower resistance, and more efficient; 2) the downside to thicker cables, is its heavier, and sometimes less flexible; 3) higher voltage will lead to insulation breakdown (these are rated for 600 VDC). For the jacket material: 1) silicone is more expensive than PVC; 2) silicone has a much higher working temperature range; 3) silicone is more flexible (wire gauge and type contribute more though). Silicone jacket is soft and tears easily. Typically, with previous 2-wires I have used (especially PVC), you can split the wires apart by pulling them apart, but if you do that with silicone, the jacket sometimes tears. Youll need to use a very sharp knife and very CAREFULLY cut down the middle. I add a piece of heat shrink tube to also stop it from further splitting. Application: Used some 10AWG to rewire a small 10A MPPT controller, which had cheap and too small 16AWG wire. While 10AWG is slightly oversized for such a low current application, it is much more efficient. Pros: Decent fit & finish; PVC jacket (MATUGAJP, SHRIBLY) or silicone jacket (HAERKN). Cons: Cost of these is higher than similar offerings; both are non-specialty wire manufacturers. RAKDSYMC didnt specify jacket material. Conclusion: At current price points, rating all of these 3-stars (non-specialty manufacturer).
