BUY 300 Watts

I’ve been working with solar panels for a few years and found them very useful for maintaining my telescope and ambulance batteries while away from city lights. The DOKIO panels I’ve purchased in the past, those with the full aluminum frames and glass, worked well with an MPPT controller, but I needed something light-weight and easy to tuck away, so I purchased this product. The panels meet my expectations, but not so much the PWM Controller, nor the cabling (wires). Although the Controller is rated at 20 amps, it’s the size of a pack of cigarettes and the wiring is too small, so I have my doubts it will work well and last. I won’t rate it here, because I have yet to give it a workout. If you want to get the most out of the panels, then ensure you purchase a minimum of 10 AWG (8 AWG recommended for long runs over 20 ft) wire that runs from the panels to an MPPT Controller rated at 30 amps to be safe. If the panels are charging a battery with a full 300 watts of output at 14.5 volts, then it will have just over 20 amps of current flowing and I never recommend using a controller that is running at its maximum rating like the PWM Controller shipped with the panels. Electronics should always be designed to handle more than its advertised maximum, just like mechanical items should always be built to handle more torque, weight, or sheer force that its rating. If DOKIO sold this package with a 30 amp MPPT Controller and 10 AWG gage wire, then everyone would be happy with their purchase. I also plan to use Scotchgard Outdoor Sun and Water Shield on all cloth surfaces to give it some UV protection (don’t get it on the panel surfaces; use a brush around the panel facing). The panels are flexible and don’t prop up against surfaces without flexing, so I built a frame out of 3/4 PVC pipe (engineered for sturdiness) that can be angled to the Sun and moved when necessary. The frame breaks down to 19 and 23 inch lengths for portability in a small pouch. I do recommend this product, but be prepared to spend a little more to suit your needs.

Added these to my anker power unit. Have worked great the couple of times i used them

This is a great lightweight kit. You can throw it in the trunk or back seat. I get enough voltage and amps to charge my 100aH LifePo4 battery with just 2 panels exposed to the sun even in low light. Something not mentioned but is an important feature, the controller has cross polarity protection and corrects if you plug in something not correctly polarized. I would have gave 5 stars except for 3 small things. The controller is a little hard to operate, the SAE plug is very loose and falls out easy, I had to buy a new cable to replace the Original. And it would have been nice to have grommets along the edges to hang from a rope or hooks on a tree or wall. This works way better than I expected.

I will give this a five star review even though I have not put it to the test yet. I bought the 150 watt version because my power station can only take 120 watt input and I would hate to fry it. It is a solar panel and i do not expect it to ever actually hit 150 watts. Even in the most perfect condition I expect 120 at the most. And my real expectation is more like an average of 40 to 70 watts because I am traveling on a bicycle with a cargo trailer attached. It lays over the trailer nice, but not every panel is getting that sweet spot of sun. I do wish it came with some kind of support to hold itself up, but for 65 bucks it was a very good deal. I am glad I did not go with a bigger one because the 150 watt is about as big as I want to get. I do have a 444wh power station I will be charging with it. I expect it will fully charge the battery in 3 about three days. Theoretically it could charge it in about 7 or 8 hours, but that would be at peak performance all day. Where I'm camping there are too many trees. It was a good price and the controller functionality is great. I like that I can plug usb devices into it directly. Only time will tell. I will update this review in about three months of abuse, I hope it holds up. Seems well built.

they are not 300 watt panels. i suspect they are 240 watt. i ordered three sets of these, they were all supposed to be new, they were all used, but in good shape. two of the sets out put is exact, one set is about 6% less than the other two for what ever reason. this folding panel kit inludes everything but the battery, but the cables are so short you will be sitcking your batter out in the sun to get charged, same with the charge controller. you can buy extensions but you need to know these panels can and i can confirm will output 17 amps @ about 13.8volts, so be mindful of your cables, that is a fair amount of amps for such low volts. the panels are heavier than i thought they would be, which can be a good thing, they fold up and can be stowed easily, but this is also a problem. they absolutly need to do be flat and angled towards the sun for good power production, like all solar panels. i think everyone leaving reviews talking about 140 watts is expecting good performance laying flat, which i understand almost all youtubers show them flat on the ground. so, they need to be propped up and angled correctly, this panel is large and floppy. i built a stand for them and guess what, now i have to tote this stand around with me, making these panels not so portable and easy. glass panels can be leaned against anything and they hold their shape, these dokio panels will flopp and bend under their own weight almost like a wet peice of paper, and they can crack if you arent careful. also, just 4 inches on grass shadow on one panel will reduce its output by almost 1/4. it appears i got more power than anyone that mentioned actual stats, and i used my own equipment to measure this. the dokio pwm controller lies, it will claim 250 watts when i am in fact getting 220 watts for example. i have all kinds of stats i can share, and i can tell you i think i found the cells these panels are made of and i think the manufacture lies about the cell stats which leads to dokio's numbers being wrong. i will tell you just a few more stats: laying the panels flat in the grass i got (not the best day for sun) : 12.72v x 7.16a=91 watts, put it up on my stand and i got: 12.98v x 12.73a=165 watts. i connected two dokio 300 watt panel kits in series on the ground and only got 12.79v x 11.01 amps =140 watts lol. one panel positioned correctly does better than two laying flat, i think the above tests were done around 2pm northern indiana in late february on medium partly sunny day using included pwm controller. since then i have had better tests and better days of sun and found this panel performs just as good on the included pwm as it does on my mppt charge controller. max power i have seen from pwm is 220 watts and about 13v 17amps= 225 watts on mppt, albeit using perfect angle charging a battery with a huge load to ensure max output from panels and controllers. this panel i suspect is made up four panels and i suspect the are actually 60 watts each not 75. also they are wired in parallel, which is not good as it shoots the amps up and while we want good amps it is important to know how V x A = W and we should have high voltage and lower amps going to the charge controller, then let the controller step it down to 12v for the battery. i wish i knew more about the internal construction as i suspect if you were to rewire these in series and ran them to a mppt you could get a 50 foot cable and get about 230 watts from them with the controller and batteries inside where its at least dry and out of the sun. i am returning these as i can and have got three glass panels that will give me about 276 watts wires in series with 50 foot cable run, according to my current test data, for about $240 and a mppt controller for about $100, which i already had for a total of $340 and they can be leaned against anything but i will continue to use the stand i built for the dokio panels. the dkio panels are over priced, they lie about its specs, they are floppy and you need to stand them up, right on the main selling page they say dont even leave them out side for one night which concerns me, the glass panels i got come with a 25 year warranty. i wanted to add that i did more testing today and two rich solar 100 watt panels produced about 98% of the power of this "300 watt" kit. i still like this kit and i bought 3 and decided to keep one, may toss it in a vehicle or take it to work for emergency power, especially since we are headed into tornado season now.

This review only applies to the panels themselves, I do not use the rest of the kit. First off, for those saying these don't product 300w, you need to understand solar panel ratings. They will produce 300w in more or less perfect conditions. So for example mid day late summer clear Texas sky pointed right at the sun absolutely they produce 300w (each set). I only use the panels, not the other stuff as I have a parallel cable setup with a pair of these panels and in the right conditions I get a full 600w out of 2 of these into my AtemPower DC to DC charger / MPPT charge controller. Your limitations are going to be environmental conditions, and your charge controller / power station setup. I run my camper electrical, 12v fridge, USB chargers, laptop charger, CPAP fans etc... and this has no problem keeping the batteries recharged / topped up. My only issues, and they are kind of the nature of the beast as it were are... #1. No included / build in kick stands to set the panels up to actually face into the sun directly. No big deal. Dokio has them available through Amazon, just don't forget to buy them, and carry the hex key with you... #2. Water resistance. You are NOT going to be charging up in a deluge no matter what, and Dokio claims their materials are water resistant, but immersion can be a problem. Keep the connectors pointed to the TOP of the panels, and if ponding / flooding is a possibility take them down and move them inside. Simple enough right? I opted for portable panels instead of roof top mounted panels on my camper to allow me to move the panels as the sun moves to keep them oriented to the sunlight to keep charging going. These are great for that, until some jacknugget pulls his big a-- fifth wheel just to your south giving you nothing but shade. Not the fault of the panel, and remember, portable, just move them! Liked my first set so well that I did get the second and built the parallel cable, so instead of 300w coming in at 18v, I now have 600w at 18v coming into my MPPT controller. (33-1/3 amps). This came with a simple MPPT charge controller, and a bag full of adapters for various power stations, none of which I use and I am not reviewing them. My only desire for any kind of upgrade is, I wish they made these in a 500w capacity, so that I could pair up 2 of them into a 60 amp controller and get 1KW into my camper, 600w is good, 1KW I can at least run AC for a while on...

Very nice set of solar panels just wish they included a set of stands because they are pretty inefficient without putting them on a proper angle to the sun. The company sells the stands separately. The stands they sell are alright but where they weld the rods to breaks easily. I posted a bad review on the stands and the company reached out to me and are sending me another set so they are very receptive to the customers needs. When used at the proper angle these panels deliver. They put out a respectable 8.8amps @ 22.5 volts open circuit. I made this setup more efficient by using a 12gauge SAE extension and a portable MMPT charger as the one they provided is adequate but I need every watt these panels deliver to recharge my Ham Radio battery’s out in the field and and MMPT charger can keep delivering power even on cloudy days . The panels are nice and light so if you have to trek your gear by carrying it a distance this is great and was my main reason for purchasing this brand. They are very thin and folded up are only about 2” thick and about 9 lbs with the controller and cables. They have a nice storage compartment built in. If I can make one suggestion to the company to make this the greatest system. Build stands into the panels backs like a photo frame has so you don’t need a set of stands. It would make these truly light and an even better product. These panels charge a 12.8 volt 20 Ah LIFEPO4 battery from a shut off voltage of 10.1 volts to a full charge in about 2.5hrs in direct sun light. The only gripe that I had was setting the provided PWM charge controller to B4 so it could charge LIFEPO4 batteries. Very confusing but I finally did it. This is one of the reasons I purchased a nice MMPT charger dedicated to charging this type of battery. You can’t go wrong buying these great panels. They also provided a nice set of accessory’s with these panels including a set of alligator clamps and multiple charging plugs. Very well thought out accessories.

Design & Portability: One of the standout features of this solar panel is its foldable design. It’s incredibly convenient for transport and storage, making it a great option for camping trips, road adventures, or emergency preparedness. The panel folds up neatly, so you can easily stow it in your vehicle or carry it with minimal hassle. Performance: The panel is advertised as a 160W unit, but in my experience, it only maxed out at 75W. This significant discrepancy means you might not get the power output you expect, especially if you’re relying on it for substantial energy needs. For instance, it took around 4.5 hours to charge my Bluetti power station to just 14%. While this could be useful in a pinch, it’s not ideal if you’re looking to rapidly replenish your battery or power larger devices. It could be user error, but I have a 100W non-portable panel that hit 90W in similar conditions. Usefulness: This panel could be handy in situations where you need a portable power source and can afford to wait longer for a charge. It’s fine for small, low-power devices or if you're not in a hurry to get your battery levels up. However, for serious power needs or quicker charging, you might want to consider a higher-wattage or more efficient panel. Conclusion: The foldable 160W portable solar panel offers excellent portability and could be a useful tool if you’re in a tight spot. However, the actual power output falls short of expectations, so keep this in mind if you’re relying on it for significant energy needs. It’s a decent backup option but may not be the best choice for primary power generation.

Panel solar práctico y facil de usar con diferentes conectores para diferentes usos,cumple con todas las características.

The Dokio 110 watt system I set up worked well in cloud and sun. I built a simple plywood support frame and let it go to work. Charging ranged from 24 volts in full sun to 13.5 low in full cloud. It was a good unsettled day to test the unit. I had two 90 amp hour deep cycle batteries hooked up in parallel and my IPad which was at 16% charge from start time. The batteries started with a reading of 12.9 volts and after after 5 hours were 13.5 volts. The IPad was at 75% charge after 4 hours. I also like the charge controller readout screen. It keeps you informed of the performance and constantly monitors the pv output. I can see that we will be able to extend our RVing off the grid considerably without worry about losing power or resorting to a generator. A 200 watt system would likely keep the batteries fully charged but for us, this will do the job nicely. Super happy so far.

Producto bueno, no he tenido la oportunidad de usarlo al 100, pero ha pasado las pruebas

Excelente produto ainda estou comprando os acessórios, recomendo a todos...

Parfait pour mettre dans le VR. Le contrôleur est assez basique, j’ai acheté un MPPT avec module BT. Mais le contrôleur inclus semble quand même correct après essaie.
