Everything works

I’ve had these panels for a couple of weeks now and so far I’ve constantly got full 200w out of them on sunny days.
Panels, frames, mounting hardware and wire were all of good quality. I am not using the charge controller and instead have them plugged into a EcoFlow River 2 pro. I ordered the kit for the wire and mounts.
I’d buy them again

Works fine, but there’s one feature I wish the charge controller had: turn the load on without a battery.
The controller has a setting to turn the load on at dawn (when the sun hits the panel) but without the battery, it doesn’t work unless you manually turn on the load. It just throws an error that the battery isn’t connected. Easily worked around by adding in a small motorcycle battery, but I was hoping to get away without that. Otherwise, it’s great.

Placed my three panels on a cargo trailer/toy hauler conversion. Great product, highly recommended.

Panels volt out and amp out to stated parameters. Had to mount panels side by side on top of my flat roof trailer and cables were to short for all three to plug into the 4 way adapter. Chatted on line with JJN Solar and the chat informed me that they did not replace parts that I had to either ask for refund or return the kit. Being i had already mounted the panels using 3MVHB, I found the easier and more logical solution was to order a set of extension cables for the one panel that would not reach. I would have been more pleased if JJN had offer this solution. The panel cables need to be at least a foot longer on these panels.
