First one I have ever bought! Bought it for my over lander build, easy to mount and charges the batteries quickly. Had a friend in the solar business help me and he was impressed with the quality for the price. Has been on two years and it still looks good, no sun fade. Only problem is birds love to crap on it.

I was shocked at the price for two of these and the size! Excellent product for the price! Works great, charged my power station quickly while on my 2 month road trip out West!

Be aware the box is big and heavy

I have to admit, I’m a solar junkie. I love anything solar, and if I can run most of my house on solar, I’m absolutely going to do it. That’s what led me to purchase these panels. I bought two 400-watt mono solar panels, giving me a total of 800 watts, and the quality is excellent. I do want to mention that these panels are very large, so definitely measure your space before purchasing so you know exactly what you’re working with. They are all so a bit heavy. Right now, I have them temporarily set up on the ground for testing. I mounted them on rails and ran the cables directly to my EcoFlow Delta Pro battery backup, and they work perfectly. Even with them on the ground, and with some trees occasionally getting in the way, I’m seeing around 560 watts. Once I get them mounted on the roof, I expect the output to be even higher. As most of us know, solar panels rarely hit their full rated wattage, so seeing 560 watts under less-than-ideal conditions is pretty impressive. My EcoFlow Delta Pro is connected to a sub-panel, which makes it easy for me to rely on my own solar power and kick in grid electricity only if I want to. Right now, these panels are doing a great job charging my batteries. I currently have an EcoFlow Delta Pro along with an extended backup battery, and I may eventually add a couple more panels to increase efficiency. It’s a great feeling knowing I can charge my batteries for free. These panels do experience a drop in output if something blocks the sun, even standing in front of them, so full, direct sunlight is best. Installation was easy and very plug-and-play. I have mine wired in series, and the MC4 connectors are clearly marked. While it would be nice if the cables were color-coded, the positive and negative are labeled, and installation was still very straightforward. They start producing power as soon as the sun hits them. Overall, I’m extremely happy with these DOKIO 400-watt mono solar 2 panels that equal 800 watts. Solid performance, easy setup, and exactly what I was looking for to expand my solar setup.
