Let's talk about the Oududianzi 10AWG solar panel wire. First off, the packaging was solid—no damage upon arrival. The 200ft each of black and red cables gave me plenty to work with for my RV solar setup.

The tinned copper construction is legit. I did my own acid test (literally) after reading skeptical reviews, and it passed with flying colors—no aluminum here! The strands are thick and conduct well, though they're stiffer than some other brands I've used.

Installation was straightforward. The wire cuts cleanly and strips easily, but be warned—it arrives coiled tighter than a rattlesnake ready to strike. You'll need to wrestle with it for a while to straighten out those kinks before installation.

Performance-wise, I noticed minimal voltage drop over a 100ft run powering my 200W panels. The insulation feels substantial and handled direct sunlight without softening—important for Arizona summers.

Now for the elephant in the room: gauge concerns. My calipers showed 2.1mm diameter (true 10AWG should be 2.59mm). While it hasn't caused issues in my low-current application, I wouldn't push this wire near its claimed 57A rating.

The UV-resistant coating seems durable after six months of exposure. No cracking or fading yet, though time will tell if it lasts the claimed 25 years.

Bottom line? Good budget option for low-to-moderate current applications where exact gauge isn't critical. Would I use it for a whole-house solar array? Probably not. For my RV setup? It's doing the job just fine.
