Like lieutenant Colombo used to say, "... and one more thing" ;) :
I don't see magic words "UV cable" and/or "MC4 connector" in description. But I do see a ghastly pigtail like those on cheap 5W solar chargers, with a male-female low-voltage connector on unknown gauge cable, and crocodiles. I had connector and crocodiles like these on my car solar maintainer. Corroded like hell in a month.
I'm afraid that you'll get what you pay for, - solar panel that is not designed to be exposed to sun and elements.
Maybe I'm wrong, and ugly pigtail can be easily disconnected at the junction box and/or replaced, and the cable is not terribly bad, and the frame is half-decent and the J-box is somewhat weather-proof. Go to Home Depot and have a closer look.
I'm picky about my solar components because consider it a long-term investment. Want it to work, and work reliably.
