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.

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

Purchased 6 of these to place on a ECO-WORTHY Solar Panel Dual Axis Tracking System. One solar panel did encounter a problem after a few months of use. However, DOKIO support was amazing and assisted me promptly w/ a replacement solar panel. Overall, these solar panels work fine. Only challenge was finding the sweet spot between connecting them in series of parallel to my EcoFlow battery backup system. I give a thumbs up to these panels!

Size: 100 watts
I bought a total of 3 of these compact size 100 watt panels. A two pack and a single panel (I needed a total of 3 panels for my project). They all arrived very well protected and with no damage to the glass or the frames. However, when I separated the two solar panels in the two pack, I immediately saw one of the doors was in an open position. Upon closer inspection, I saw one of the door latching clips was broken off. I found the broken latch clip at the bottom of the solar panel. I was very disappointed at finding this. Other than the broken clip, the build quality is very good. They does have proper diode protection. MC4 connectors are well made. The panels all put out between 90 and 94 watts when I tested them on a somewhat hazy day. Do I did not expect to get the full 100 watts rated due to the haze. But I am pretty impressed with watts on such a hazy day. Other then the broken clip, they panels appear very good.

These solar panels are good for the price as far is my limited experience with solar is concerned. Was able to get over 330v peak Jan 1 at about 11:50 when the NY temp was 29 degrees from just one of the 400w panels. Have not connected the other yet but am optimistic that it will perform just like the first. Must advise that these panels are super huge and heavy though. Connected it to a power station which I also got from Amazon and was pleased with the charge rate. This result encourages me to expand my solar power interests. UPDATED REVIEW. These panels are capable of outputting even more than the nominal peak power. Was able to get 838 watts form the two 400 watt panels connected in series while feeding a 3600W, 3840Wh power station. Panels are inclined southwards at about 50 degrees in NYC at mid-day in January.

These look like quality solar panels, but the way the manufacturer packaged them, they should never have gone through a shipper. The packaging is more suitable for a retail location and one of the two which I ordered was shattered and the second one which was not broken did have dented corners.
