DOKIO 100W 18V Flexible Solar Panel Monocrystalline for 12V Battery Charging, Semi-Flexible ETFE Lightweight with MC4 for RV Marine Boat Camper Van Trailer Off-Grid Power

I am very happy with these. I've purchased more expensive, rigid, bifacial panels and these have done better side by side. And incredible light and portable. I kind've thought I'd sacrifice some power output with such affordable, flexible paneIs; but they do better. I just laid them flat in the yard on a partially sunny day. I ran them in series and it was putting out 77 volts, over 350 watts. They have high output. They have MC4 connectors so connecting up parallel or in series, 1 or all 4.They charged my 100ah battery quickly. I connected to my Anker but it was over voltage. I'll have to run them in parallel pairs. 3 worked. So I took the other to charge up things around the yard.I'd like to build light frames for them in the yard, anchor them. Move or turn or put them away as needed. Or I thought I'd hang them in the fence facing south. That would take just minutes.One of these would be great on a trip for charging things but four for this price is a good deal.Now while comparing these to the more expensive ones I did notice they did not do as well when shaded or if in series and just part of one panel is shade or blocked and virtually all power is lost. But run then in parallel or use them as portables. The expensive ones did not lose as much.I have found a great use. These four panels and a power station are able to run a larger window AC for about 6+ hours a day. It could be more as they only catch sun for half the day.

After using it for 3 months the seal started peeling off and now the solar pannel is only working at no more than a 43 % charge. So in a nutshell it didnt last after all the trouble to secure it and now how to remove it . I contacted the manufacturer and nothing yet ..

Output is good. It's flexible enough, but won't last for years. It's kind of a entry panel to get into the solar power. So don't expect a lot from it, but it will do what it's rated to do. It's not pretty, it's not that durable, but it does the job and it'll last till you inevitably upgrade

I connected in series and registers at 34-39 volts at solar control (MPPT) with "2 panels" after making light wood frames for them. The panels are not as good as some others I have used possibly but performance is definitely better than some of the ridgid panels I have. I might have better results with a different brand of MPPT controller, as of now I have limited experience with the panels. The two panels are keeping the 2 100 amp LiPo batteries around 13.6 volts but my area has received a lot of rainy weather and I'm not sure of the controller performance. The panels are light weight and I got them on a sale price so if they do as good as some others I have in good weather worth the money. My travel trailer is not conducive for mounting panels on the roof. I will try to give more to the review after having them in use for some time.

The media could not be loaded. I purchased 10 of the 100 watt solar panels I was highly skeptical at first and was about to return them all because they were barely getting 45 watts but it was pretty cloudy. I have a 50 watt foldable panel that will get that wattage in clouds AND rain but I decided to hold off and give them a full sun test since my primary need is going to be during sunny weather. BEST DECISION EVER! These things don't look like much but they are believe me!. 9 out of the 10 got mid 90s wattage except the one I used in the stat test video. It got 87 watts. But today it got 90. They're extremely lightweight & way more flexible than I expected them to be. Honestly for the $59 a piece I paid I am extremely happy with the purchase. Definitely great value for the money. I bought 10 thinking I was going to need that many to run my 1,200 watt inverter to run my window AC in my van but ONE of them kept the battery charged and my AC running all day. I will say this though these things will shoot up in the voltage and FAST so if you have sensitive inverters or appliance be sure to regulate with the charge controller. I set a calendar reminder to do an update at the end of summer which in Texas in long but if they survive this sun here then they'll pretty much survive ANYTHING!!

Bought 6x100 watt flexible panels, these are linked 3S2P for a 60volt x 10amp load. I feed the input to a MPPT charge controller that maintains 2x100ah lifepo4 batteries. Panels have impressed me. Let's be realistic thou when you're weighing out your options. Fact 1) these panels feel like they want to break under their own weight. Fact 2) they need something to support them. Fact 3) lightweight like a slight breeze will carry them away Fact 4) these panels produce power from before sunrise to after sunset Fact 5) no frills, no gimmicks, no BS just solid basic power production. I'm just east of the Appalachian mountain range just a little south of the MD line. 11am on a clear day I've seen 606 watts max. At 6:30am with nothing more than a skyline silhouette of orange I've gotten 6 watts. Typical output hovers around 500 watts with clear skies. Low cost high output option if you're curious about solar this is an excellent entry level product. I'm planning to double my system soon and I'll be getting more of these exact panels no questions asked.
