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)

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).

Broken insulation. Exposed the internal copper wire! Can only be cut into two short, not satisfied!

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.

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 50 feet of red 10 AWG PV cable as represented.

Just buy it its wire! LoL

No complaints, and it arrived sooner than expected.

I have some other cable from Shirbly and the quality of the cable appear to be top notch. Nicely packaged, flexible, think insulation, and it looks so nice. The lettering on the cable is very clear and easy to read so it should be clearly readable for many years. I didnt want something cheap and so far Shirbly has provided some really nice cables. Not the most expensive either so definitely worth the price. I highly recommend their products.

This wire is exactly what it states it is. It comes in the value that is quoted in my case which was 50 feet. The wire itself seems to be very well manufactured. It also seems to be the correct gauge stated. So far I’ve use this to wire together a battery box with the solar charge controller and inverter. So far in my application it has been great and in the future I will definitely be placing an order for more. I would absolutely recommend.

Good wire.
