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)

Im sure as flexible as this wire is at room temperature that cold weather will be no problem. It is a little tougher to strip but that speaks of durability long term. Be watchful as you use heat shrink tube on wire and crimp fittings. Too much heat over the wire will soften and partially melt the insulation. I consider that a watch and not a deal breaker. You can get a good shrink without harming the wire if you know your gun and dont play the heat over the wire excessively.

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).

Nothing

It transports electricity. No problems so far.

Just buy it its wire! LoL

78 strand tinned copper, flexible, good choice.

This cable appears to be exactly as stated... 10AWG tinned copper PV cable. Its marked Kibor Cable as the manufacturer. Wire diameter was to specification. Total length was to specification I ordered. Materials appear to be as-stated, with tinned copper conductors and a very tough, durable UV-resistant insulation - as required for PV interconnections.

Shortly solar panel wire 30FT 8AWG I ordered two sets. each sets only have 29 ft rip off reasons for not returning I live overseas take too long to reorder. measure before installing!!!!

I needed to make an extension cord for a solar panel and needed 10ga high quality wire that was waterproof. This product met my needed.

This wire seemed to be just a hair thicker than other similar gauged wire that I own and use regularly. The caveat to that is it is not quite as flexible but not much of a difference and thats actually a good thing as it speaks to the wires quality! Fully tinned solid copper wire true American wire gauge makes soldering a breeze for the crazy people that like to solder big wires like I do. The tinned feature also prevents copper oxidation and double layered wire leaves for a rest assured safety aspect that is sought after on any high current electrical install. Im currently using this on a solar application but you can use it on just about anything electrical with the safety of this wire. You cannot go wrong with this wire I highly recommend it!
