Set name: 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.

Works just fine keeping a little 20ah AGM battery juiced up for camera's and actuators on my solar arrays. Sometimes it's just easier and cheaper to put a mini system together than running cable at today's prices. And this little panel fits the bill perfectly. Provides more than enough power for the need. If I can only convince my cats to stop laying on it... :}

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 do 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. * * * Update * * * I finally got around to mounting these on my 4Runner. They are wired in series for the 36V 50Ah LiFePO4 (Lithium Iron Phosphate) battery I use to supplement my Bluetti AC180. The power from the solar panels go to my Victron MPPT 100/20 solar charge controller. The solar charge controller charge my 36 volt storage battery. I then run a line directly off my 36v battery into my AC180 solar charging input port. The AC180 charges at around 375 watts per hour to keep it topped off all the time. It works great! In direct sunlight, I get about 270 watts out of the the solar panels. Keep in mind my panels are directly laying flat on the roof of my 4Runner. As such they are not tilted towards the sun for maximum performance. So considering that fact, they are working very well.

I did purchase 4 of DOKIO 400W 31V Mono Solar Panel - Works for 12V/24V Systems, I did install as series 2 panel to produce more voltage about 75 to 80. works in voltage. But now wattage or amp. I connect to one of the Grid tie inverter which soport 90v and 2.000 watts . Don't work. Only work on 12vdc.and 24v.aftrr that is trash. I have 4 of the 24v 320 watts renegy I did install in series they work fine. I think the DOKIO 400W 31V Mono Solar Panel - Works for 12V/24V Systems, is trash for series. Is my opinion and experience buying and having more trash.... Please check before you buy I don't want you throw your money away

I just bought some of these 200W kits. I am somewhat of a neophyte, but for now these seem to be working OK. Time will tell. I tested them in pretty good sunlight, but the panels were on the ground not perfectly aligned with the sun or anything, and at one point I got 323W when I hooked two in series. This shows me that they are basically working, but I need to install them on the roof, etc. There are some "issues" with the ad, as it turns out. These existence of these issues and the fact that there have been no replies made me switch what would have (naively?) been 5 stars to 4 stars. Issue 1: The ad images and specs suggest you get two 100W panels. You get (at least I got so far) one 200W panel per kit. The panels are labeled on the back, and have the same voltage and twice the amps of the 100W panel shown in the ad. I alerted the seller (DOKIO) and there has been no reply to me and no change to the ad. Maybe it takes time... Issue 2: The ad shows two images that show how to wire these panels. Each image shows series and parallel wiring. It is my opinion that one of the images is incorrect for series wiring. I alerted AMAZON and there has been no reply to me and no change to the ad. Maybe it takes time... 2025-04-19 update: I noticed what I bought is no longer offered by the seller, but a 200W kit with a picture of a single panel is shown now. So I suspect the product is still available, just under a different ad. I noticed the series-parallel picture is gone from the pictures you can browse at the top of the ad, but in the body of the ad there remains the picture of the series hookup that I believe is wrong (has ++). (They got rid of the correct picture that had +- instead of ++.) (If anyone out there can prove I'm wrong, I'll all ears.) I also noticed that the "specs" were labeled 200W but the numbers still seemed to be for the 100W panel, e.g., maximum power 100W instead of 200W. I have tested four of these panels by just placing them on the ground. At one point I measured 616W (the max I noticed in a 4-panel 2S2P configuration), which I consider acceptable under the circumstances. I am leaving the rating at 4 stars, although, come on -- placing a new ad with a single-panel main picture but also removing the (I claim) correct series picture and not checking the rest of the ad and making appropriate changes? This lack of thoroughness seems not to be reflected in the product itself. I doubt I'll check the ad and update this review. 2025-04-22 update: my second batch of four 200W solar-panel kits arrived yesterday. Instead of four 200W panels, four 100W panels were delivered. (I did not open the boxes. The boxes were half the size of the 200W panels.) Because of the arrangement between the seller and AMAZON, all I was able to do is return these four panels for a refund and free shipping pickup. To get the four 200W panels, I had to make a new order. The price is higher now. And there is a wait of 1 to 2 months before delivery, assuming 200W panels are delivered. And I am changing my review to 3 stars. The four panels I already own have worked fine every time I tested them, but they are out of service now until and if I get my project completed. My project is on hold now owing to a lack of panels.
