  • High-quality solar panels delivering impressive real-world performance!
Size: 800W
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. ... show more

  • The rating doesn't match real-world input.
Size: 800W
I waited a good three weeks because I wanted to be fair and if it changes when we get it more into spring and summer I will edit this review but right now they're not for 300 watt panels. I can't get even 70% of the 400 watt rating. I'm in mid-60s. These should be rated as a 300 watt panel. My house is south, facing, and west facing with zero trees. I get 100% sun I should be getting more than 60% on these panels. If they work better, when it gets warmer, I'll edit this review. But right now, they are not 400 watt panels. ... show more

  • Junk. Don't waste your money.
Size: 800W
Junk! I bought these solar panels to put on my new motorhome. I installed 1 400 watt panel and right now in decent sunlight I'm barely pulling in 30 watts. My other van with 400 watts of Newpowa solar panels is pulling in 200. I'm sending these back and going with a different brand. And oh yeah now I have holes in my roof I have to fill in. ... show more

  • Good solid performing solar panels

Low cost panels but they deliver just as good as the expensive panels. 600-800 watts consistently 👌

  • Overstated power output.
Size: 800W
Some solar panel makers advertise the correct output. This company is not one of them. The panels are well built but I could only get about 200 watts out of them in direct overhead sun at 12 noon. Suggest buying something else, you might be disappointed like I was. Another reviewer had about the same poor output. ... show more
