  • Thick insulation for 10 gauge pv wire
Size: 20 Feet
The wire came just as pictures. One bundle of red and one bundle of black. The insulation is thick. My only reservation is the "tinned" wires. This is stranded wire and it looks like the strands are partly made of aluminum which can be less conductive and other problems compared to straight copper. Also this wire is much more stiff than the damaged wire I pulled from my panel. I don't think that is a problem but just something to consider. I thought about dropping a star but I feel the product is true to what is advertised. I tried splicing an end and it was easy enough. The hardest part was stripping the thick sheathing. ... show more

Plus offering 10 AWG in a 20 foot extension will make you feel confident that you won’t have any energy loss issues. Of course, it is perfect for its intended use for solar panels, arrays, inverters, charge controllers and portable batteries This is a high-quality,10AWG tinned copper wire.

  • Robust and Reliable
Size: 20 Feet
I recently upgraded my solar setup with this 10-gauge solar wire, available in both red and black, and it has been a solid investment. The thick wire is heavy-duty and feels built to last, which is exactly what I need for my outdoor solar projects. The insulation is thick, ensuring that the wire stands up to the elements without any degradation in performance. This is crucial for any outdoor application, and this wire delivers on that front. Its great insulation also means safety is a priority, giving me peace of mind that my solar array is not only efficient but also secure. The wire’s thickness makes it ideal for those who are serious about their solar power and want materials that can match their commitment to renewable energy. This 10-gauge solar wire is a great choice for anyone looking for reliable, well-insulated, and heavy-duty wiring for outdoor use. ... show more

  • Good quality wire, built tough.
Size: 20 Feet
This is good stuff. As other reviews have mentioned, the jacketing on this wire is not very pliable and is difficult to cut and strip. That's to be expected with double-jacketing designed to withstand harsh elements and abuse. This wire is tough. The wires themselves are arranged in 7 bundles of 15 wires each. Each wire is copper, tinned against oxidation. This wire should comfortably handle the rated current and take a beating. ... show more

  • UL listed cable, tinned copper
Size: 20 Feet
FIRMERST 10 Gauge Solar Wire Red and Black Each 20 Feet for Solar Panels UL Listed Firstly this checks out, I verified that the company who made this does actually have a UL certification and they do. If you search for the listing on the wire which is UL E480012 you will find the certification details for this company/factory in China. As you can see by by close up photo the multistrand wire is real copper and this has a lot of insulation. Thank you for reading my review and looking at my photos of this product. I hope you found it helpful! REVIEW PHILOSOPHY: I only review a product if it is something I am capable of critically evaluating through comparison, testing and use. This means I have experience of using similar items; or that I have equipment or tools that I can test it with; or that I have an upcoming need so I can actually use. I am as selective about getting an item to review as I would be about purchasing that same item, so yes, I expect it to be a good product. My reviews are NOT based on packaging or if it was delivered timely. ... show more

  • Not to good ....
Size: 20 Feet
Typically solar power wiring has specific ends to insert into the controller box and panel. However this is just basically simple cheap wire with no end.

  • Reasonable Comparable Price & Quality for 20' of 10 AWG Solar Wire
Size: 20 Feet
I have a few small solar panel systems I use (RVs, power box, home, etc.). I needed extra wire for my projects and saw this product advertised on Amazon. The comparative price for 20 feet of 10AWG solar wire was very reasonable. When I recieved the wire it appeard of good quality. The package came with what was advertised. Both the red and black wires had twisted, tinned, copper-in-center conductors which also appeared to be10AWG diameter. I uncoiled the wires and they measured at 20 foot lengths. Using my electrical multi-tester, both wires (mostly uncoiled) showed continuity and ran about 1.9 ohms, or .001 K-ohms, end to end, if I used the tester correctly. The wires had (UL) E480012 Jiukai PV WIRE 10AWG 90(deg) C WET OR DRY 2000V SUN RES -40(deg) C printed along their lenghts. ... show more

  • Perfect for running solor - wire is a bit on the stiff side.
Size: 20 Feet
It will work fine for its intended purpose. I have had solar cables that are highly pliable and some that are stiff - these are definitely on the stiff side. I also found that they are tough to strip - but that is pretty common with wire that is this thick. It is a nice stranded wire and it does crimp well. ... show more
