    Excellent quality, questionable setup.

    The build of these solar panels is top notch!They have a solid heft to them and I had no fears of their durability or weatherproofing.They have nice connectors and I was able to get approximately 80% of the rated capacity in full sun which is quite good.Two things that could be improved however: – The cables come out of the front side of the panel which makes routing them a bit of a challenge, especially if you plan on having the power station positioned behind them. If the cables were in the back like a solid panel, it would avoid needless bunching potential shadows cast by the cables on the front.- The way to stand these panels is honestly frustrating. There are 4 clips that attach to the case and panel and prop it up. To move or set up/tear down the panels is a chore and just feels clunky compared to other mobile panels which have fold in stands on the back.Overall a solid panel that’s portable and well built, with a few minor tweaks it would be above reproach.

    Solar Panels are awesome!!

    The 220W solar panels from EcoFlow work great with the EcoFlow delta pro. Even on days that are partly cloudy, I get a charge to my batteries. I would definitely recommend these panels.

    kick stand case. Has a lot to be desired.

    220 watt panels are fine but that kick stand case is a real pain to use. Don’t even think of buying one of solar panel sun alignment tool and keeping your panels in the optimal relation with the sun. It will just drive you crazy. Best to come up with something on your own.

    Heavy solar panel, performed above 80% efficiency, dependable solar panel

    The media could not be loaded.

    This is my 4th solar panel that is larger than 100W, 2nd one that is rated 200W or higher. EcoFlow 220W solar panel is one of the few bifacial solar panels in the market. The front is made of 220W solar panels, and the back side has 155W panels to catch ambient light. The extra back solar panels add overall weight. The solar panel is weighted at 20.9lb. It is not too heavy but hard to setup when working with 4 large panels and with hurting hands.It is not hard to setup and point the solar panels to the sun at the right angel, but to make it easier I also bought EF solar angle guide (ASIN: B0B3J3B2W5) to help. I have setup the panels early in the morning and also at noon time. In SoCal, the temperature in June-July ranges from mid-70’s in the morning to high 90’s Fahrenheit during the day. I can consistently charge my EF Delta mini (ASIN:B09C8GCP8F) at 180-185W on a clear day. Sometimes it would produce burst output of 196W, but does not last. The temperature doesn’t seem to be a big factor. I am not sure how much energy is product from the back side of the panel since EcoFlow only advertises this solar panel at 220W and not the combining wattage of front and back. The efficiency of this panel then is about 82~84% which is within the expected range. In Ecoflow user discussion groups, some users are able to achieve above 200W. I have tried several weeks by position the solar panel at different time, angle, reflectors, and with the help of solar angle guide, but nothing helped to achieve close to 200W. I think it is probably due to the air quality of the area. With a slight haze in the sky, the output will drop 10-20W. The only way we can get a totally clear sky is after the rain.Ecoflow 220W solar has performed within the expected range. 5-star at this time.

    Nice, But Need Better Documentation

    This array is high quality and well made. However, I have not been able to figure out the best orientation for my circumstance. This has been complicated by poor or nonexistent documentation. Nice equipment but one needs to learn how best to use it – sometimes it’s the little things …

    Works for the job

    This seems well built. need gloves after it has been in the sun for hours. tested at 5:40-6:20 in the evening and during a sunny day all day. best i saw was 165 Walls but guess that’s an average of any solar panel. the case looks well built and holds the panels well. foldable and transportable for camping is what i wanted. if you want good charging get 2 to 4 depending what your charging system can handle. the delta pro will take 1600 solar. more panels faster charging. 220 solar panel,1st test was at 5:40 pm plugged into my delta mini, mini started at 18% the panels started at 160-165 watts. Stopped it at 6:20. 30 min test. The mini was at 28% so gained 10% in 30 min. given the 10% at 30 min you would think 3.5 hours more would be 100%. So 5 to 6 hours from 0 to 100% if you could get 165 watts constant.220 solar panel on the delta pro starting 8:34 AM, the power was at 27% started getting 127 Watts but ranged up to 160 watts by moving the panels through the day. Unplugged at 5 PM losing sun. Was at 53% a total of 26% gain in 8.5 hours. Not good enough to charge a Delta Pro in 8 hours, 1 day of charging. Need more panels/ power.

    Solar newbie (also theory about the missing cable)

    I recently bought an Ecoflow River 2 Pro and then this 160W panel… my first experience with power stations and also solar.Re. the panel… It seems some people got the solar cable with their panel and some didn’t. In my case, I did NOT get it, even though their support told me that it WAS included. I contacted them via chat and they have now sent me an email saying that they “will” send a cable, but I haven’t received it. Having said that, and now that I received the panel, I have a theory about why some get the cable and some don’t. I heard (don’t remember if it was from support or from a question/answer here) that they started shipping the cables with panels sometime during 2022. I noticed the box my panel came in had a date of 8/2022, so I think that what is happening if they may be shipping some older stock in some cases, and if the one you get is before when they started including the cable, then you won’t get a cable with the panel. Hopefully they’re doing what they told me and are sending my cable!Overall, and although this is my first time working with a solar panel, it has been interesting. It appears that the River 2 Pro won’t start charging until the panel is putting out a certain voltage or current, and if it not enough, the River 2 just says 0W (at first I thought the panel wasn’t working). I have the panel in our screen porch area, so it is semi-indoors, and best I’ve been able to get is 46W and I have to keep moving the panel around. I guess if it was fully outdoors I might not need to do that, but this is a kind of learning experience for me.As others have said, the bag as stand works, but it is kind of awkward and floppy, but it does work.

    Not sure it’s all it c

    I’m new to solar generators and solar panels. So my opinions are based on a first time user. I chose the 220 watt bifacial solar panel because is made sense to garnish extra power from the back scatter. I was anxious for it to arrive. I finally received it I couldn’t wait to try it out. Unboxing was simple with short instructions. Almost none on how to use the case to hold up the panel. I line in Central Texas and my trial was done around 1 pm on a very hot, 101 degrees at the time, cloudless sky. The sun was directly overhead so I laid the panel flat and plug it in to my new EcoFlow River Pro. I watched other YouTubers get 160 to 200 watts out of this panel so I was disappointed to find that I was only getting 107 watts. Perplexed, I tried many configurations and angles. Still I only got 197 watts. Thinking the panel was defective, I called the support number. She led me to turn on and off several features on the app. No success. She told me to continue to try different setups. So I posed my trouble to Amazon customers and Jeremy came through with the answer because he had the same issue. He told me to turn off “slow charging” and that would cure the problem. And it did. So I spent the rest of the afternoon moving the panel to keep it facing the sun at 90 degrees. The highest I reached was 170 watts. I don’t no if the extreme heat was affecting the output, but I can live with it. I did experiment with it though. Since the backside gets more efficient with higher reflective surfaces, I surmised that a reflective blanket was do the best. I used an Arcturus Heavy Duty Survival Blanket. It’s large, 5’x6’, and better built than others. I tried different configurations, panel sitting on it, hanging from the case with curve towards the panel and lying if front of the panel. I didn’t get any increase in wattage from any configuration with the reflective blanket behind the panels. I did get a 5 watt increase with the blanket lying in front of the panel. To make sure that the backside was working, I turned the panel upside down and it was putting out around 55 watts. I have no idea why I’m not getting of extra wattage that this panel was designed for. At least I’m getting adequate from from the 200 watt side.Using the case to hold the panel works, but what a pain! After getting configured for the current sun position was fairly simple. But when it come time to move it, it helps greatly to have two or more hands. By yourself, expect the case to fall, get twisted, and take forever. My best solution was to anchor the bottom, non-rigid side. That helps tremendously. I’m looking for other methods besides that case. The case does simplify the amount of other equipment you have to bring to set the panels.Overall, I think the panels and case work well and with the expense.

    Great panels

    These panels work as advertised. It was originally delivered missing the cable that attached the panels to the battery, but after a quick chat with customer service, they sent me the missing cable.One thing that none of the instructions say is that there cannot be any shadows or spots on the panel that sun isn’t hitting. If the panel is in an interior window with a small section out of sunlight, it will read 0. Since it is the first time I’ve ever used a solar panel, I assumed you could set it up in a window, but it definitely needs to be completely outdoors to generate power.

    Solar panels output impacted by shadows

    The cells on this portable solar panel must be hooked up in series, because when a shadow covers just a portion of the solar panel you will get zero solar input going to your solar generator. Mine was hooked up to a Delta 2. So in order to work, the solar panel needs to be completely covered by the Sun.I placed 1×2 strip piece of wood behind the solar panel to make it more rigid so I can angle it to face the sun, increased output by 10%.Made a collapsible solar panel mount that can be attached to the south facing brick wall. Has the longest amount of sunlight without shade. Also keeps them at the optimal angle to the sun. Just some 1×2 and hinges.

    Hooked up to two other panels and powering a Delta Pro and extra battery. Works great. The stand (carrying case, opened up) is a little less robust than it could be, but it gets the job done and the panels stay upright.

    Doesn’t Come With All Adapter Cords Needed

    After much research online and watching lots of videos, I purchased the EcoFlow Delta Pro, Smart Dual Fuel Generator and 400w Solar Panels. The units are excellent quality and I believe them to be a superior product so far, however, the first time I tried to charge my Delta Pro with the generator, I discovered that the adapter plug that’s required to attach the Gen set to the unit via the Infinity port does NOT come with either the Delta Pro or the Smart Generator. It’s ridiculous that EcoFlow does not communicate this well and even more insane that this item is not included…even if they increased the price to compensate.A few days later, I decided to charge my Delta Pro with the EcoFlow 400w solar panel array only to find out that the solar panels didn’t include the “solar panel to xt60i” cord! Insert head explosion. It’s not about the money, it’s the inconvenience and stupidity of having to hound-dog the basic necessities to make this stuff work. I would still purchase them but EcoFlow needs to sell the adapter plug with the generator and the adapter cable with the solar panels.

    Really big and difficult to aim correctly

    It’s great to be able to charge my River Pro 2 but it’s very large and difficult to aim towards the sun being so large. It takes up a good bit of room and is pretty heavy.

    I’d rate it higher if I could use it

    From everything I’ve read this will be great but since it shipped without cables and I’m waiting for Ecoflow to get the to me, maybe sometime next week, I can’t give a full review. Heavier and larger than I thought they would be but that could actually be a good thing. The case could probably a little more protective but that’s easily solvable with some corrugated plastic.Update. After a little back and forth Ecoflow sent me out a set of xt60 cables to replace the ones that were missing. Took a few days to get them and then try them out but things seem fine. I added a star on because they responded quickly but since they missed them to begin with and only sent out xt60 and not xt60i holds them back from a fifth star. Getting things right the first time would have garnered a 5 star.

    Quiet and portable

    We got this as part of a back-up power system. We had 2 sunny days and hooked it up to The Ecoflow Delta pro. even with winter sunlight we got a 50% charge in about 12 hours over 2 days. It makes no noise or air pollution during use. It was a little awkward to move by myself, but not bad for 2 people to set up. We will try a few locations to see where we get the most light.

    First try…..

    First time to use this on my new Epoch LifePo4 camper batteries. Crazy wind here 20-30+ mph so I improvised a stand from an extra Lifetime folding table, some Nite Ice flex ties and a couple of tent stakes to keep the table stable in the wind. It is feeding 12.5 amps to the batteries without any technical positioning sitting on grass. The kickstand included with the panel would be worthless in these windy conditions which anyone should know if they investigate reviews. Later in the day I was able to get over 15 amps.

    Excellent 400W Flexible Solar Panel!

    Although I purchased our two Delta Pro generators and 400W flexible solar panel last month, I only used the solar panel on two occasions due to inclement weather, but when I did use it, the solar panel worked flawlessly to keep the generator(s) charged. During the week after receiving the solar panel, my husband decided to build a frame to support the flexible panel and placed it on a wheeled cart to allow me to easily move the panel in and out of our garage. What a gift! Now I am able maneuver the panels into a perfect position for optimal sunlight and keep my generators charged. I would like to add that I have dealt with EcoFlow’s customer service on several occasions to ask various questions, and they have not only answered all, but have followed up with email and a phone call to make sure I am satisfied. EcoFlow’s customer service is the best! Great customer service, solar generators, and solar panel makes me a very happy person!

    As a full-time overlanding nomad, I’m using this solar panel with my ECOFLOW River PRO 720 Wh power station. Between these two items I am running a Dometic 25L or Alpicool 35L fridge/freezer, an array of USB charged devices, a laptop and drone batteries that require occasional charging. Most of these devices run all day and night. Throughout the day, the power station stays at 100% of its charge.At dusk the power station, of course, is no longer taking a charge. Typically at pre-dawn the station may be drawn down to 75%. By 8:30 AM it’s back up to 100%. This tells me that I can ask this combo to do more with no expectation that it will ever fail me.Meanwhile, if I ever draw it down beyond its capacity in its cut configuration, I can add a River PRO extra battery bringing my storage capacity up to 1440 Wh with no doubt that it will return the system to 100% charge by mid-morning.Initially I rotated the panel for optimal orientation to the sun. Now I simply place it over the windshield of my vehicle and point it due south. In this way, ideal orientation occurs only at noon. Before and after that, it’s at least slightly off axis and the system still outpaces any load I’ve created so far.Now that it’s getting cooler I may get a 12 volt DC electric blanket to ward off sub-freezing temperatures. My expectation is that whatever load I add with it will be offset by the fact that, when it’s in use, the fridge/freezers will be drawing less.I plan to get Starlink for broadband comms. I’ll do another review to report on whether or not that pushes me into needing the full 1440 Wh potential.

    Saving money on electric

    The solar panel is so amazing charging up my solar generator from the same company. I went and bought a second one more can I say it’s an amazing product taking the sun turning into electric I have the Delta Max too and the river two pro that I power with my solar panels, it’s a win-win situation. Thank you so much.

    Heavy and awkward….

    I was a little disappointed with its weight and maneuverability. Hopefully EcoFlow will rework this design. The case is not durable and does not provide the required support to let the panels work at optimal performance. It’s a shame because they are expensive!!!!!!

    Ecoflow 220Watt Bifacial is up to the task

    I purchase the panel back in March 2023 and I used it almost everyday when the sky is clear. The panel consistent provide 140-220watt under sunny condition. The portable panel is solid and well built, even the kickstand case look like new after 6 month usage.There are couple cons from this panel, the kickstand is not that easy to deploy, hope ecoflow can come out with better kick stand. Also. after so many time folding and unfolding the panel, thin plastic/film at the adjoining section started detach from the panel, however it did not impact the performance.Conclusion, this is portable solar panel is up to it advertise task. It is easy to move around using it kickstand case and can be deployed in few minutes.

    Unmatched power, but not without other flaws.

    I tested this panel against over 10 other foldable solar panels of similar (200w) class power. This panel, ranked number #1 in power delivery. I was able to get 200w under clear sunny skies, during Spring in the Midwest.However, it’s not without some notable drawbacks.Below are pros / cons:Pros:Unmatched power delivery; In my tests I got 200w in *ideal* conditions. 185w in average conditions.Seamless water-proof design is nice.Cons:Most expensive panel in comparison.Glass imbedded within the panel could break,Heaviest panel in comparison.Panel has no handles and gets *extremely* hot under the sun.Edges of panel warp under its own weight.No built-in stands, but must use case to prop-up and angle towards sun.Using case as stand is awkward to setup.Panel can be difficult to open (very stiff) and/or keep open when temps are colder.Case is heavy and when the panel is inside the whole package is quite heavy for a “portable” panel.

    It works pretty well

    After the learning curve period (i.e. position, angle, weight, folding, etc.) been using it to charge my portable battery devices that have high storage capacity in terms of KWH, so far so good. First time I struggled a little with the weight as it is a little heavy and folding it to put it in the case. The best I gotten in terms of charging is around 189 KWH, it really oscillates between 125 to 189 KWH when the the sun it unblocked and the proper angle. Really a good product, very happy so far.

    My Favorite Solar Panels

    I bought this solar panel after trying several other brands to be paired with an Ecoflow Delta 2 and several other lifepo4 batteries. I am very pleased with this panel I have 200w Massimo, JJN 200w bifacial, Bluetti, 110w Ecoflow, and 220W bifacial eco flow. So far, this 220w bifacial panel is my favorite. its high-quality build and performance beat other brands. I have been using solar power for most of my electric needs. Whether it be charging my laptops, TV, phones, smart devices, or a way to power all my kitchen needs.Even on cloudy and rainy days, this solar panel doesn’t disappoint. This panel really blows those out of the water. Obviously from a shear wattage standpoint but more importantly in less than ideal conditions. The bifacial panels have proven to be awesome in cloudy.The carrying case and stand, while not perfect, do a great job of protecting and carrying the panels. It’s rugged and has no concerns about it getting wet or dirty as it’s very repellant and easy to clean. When I took it out the first time, I have to bend the panels backward and hold them for several minutes so they can stay straight. The cables are very high quality and very durable. The X60I cable allows for higher amperage on the eco flow and can fully charge the delta 2 in 4-5 hours.I highly recommend this panel. I will buy more when it is on sale again.

    Need better Support Stand MC4 Connector Placement Issue

    Pros: Good power generation. That’s pretty much there is to say.Cons:Most expensive panel in comparison.Glass imbedded within the panel could break,Heaviest panel in comparison.Panel has no handles and gets *extremely* hot under the sun.Edges of panel warp under its own weight. Needs built in stands to support. The stand/case that is supposed to support it works, but not very well. Beware putting this on a table as the stand will not stay in place, causing the panel to slide.Panel difficult to open (very stiff) and/or keep open.Case is heavy and when the panel is inside the whole package is very heavy for a “portable” panel.MC4 Connection is on the front side of unit. This could cause the connection to overheat possibly deform in high temperatures.I really wanted to like this unit. I’ve seen several reviews and the reviews matched my experience with the power generation. However, the bulky size of the unit, and it’s weight it isn’t truly a foldable portable solution. If Ecoflow could go to a two panel unit, move the mc4 connection to the rear side, and add kickstand for support, it would be a far superior unit. Due to the factors above, I would not recommend this panel for older folks unless they have strong backs to endure the intial setup and placement.

    Needs the cable!

    Bought as a bundle of a solar panel and power station but it did not include the cable to connect the two.

    Good power from a portable unit

    I bought this panel along with an Ecoflow Delta Pro so that I could power my garage related appliances and electronics. I am currently running my garage refrigerator, a couple of battery maintainers for my cars and a motion activated light that comes on when I walk into the garage. The panels does a good job of charging my Delta Pro on most days and even charges a bit on hazy days, but of course not as much. It’s winter time now and the sun is low in the horizon and shines fewer hours than in the summer so I’m thinking that I will be able to connect more things to it once summer rolls around. So far I am very pleased with its performance and I think it is only going to get better. The panel is portable but it does weigh a little bit due to its robust construction. I prefer that it is tougher and a bit heavier than lighter and flimsier, especially if it is going to moved about from place to place. It’s not exactly cheap, but then you do get what you pay for and this is worth the price.

    Excellent 60 Watt portable Panel

    Very high quality unit. I pair this with my Anker 548 battery station with the XT60 solar input and it works fantastic. The moment I plugged it in around 1PM January California sun it was hitting 48-55 Watts charge with partly cloudy skies and thin cloud haze blocking the sun. It settled in at around 53 with less than perfect sky. Very impressed by this. These are high efficiency 23.4% cells so I am pretty certain I will get 60 watts on a clear sky.The build quality is very good. Case, zippers and fabric backing all feel really good. The redesign of the kickstand was a major selling point. No longer requires using the case to prop up the panels. Definitely worth the purchase if you are looking for a good portable option with stellar performance.

    Quick review – ECOFLOW 220Watt Bifacial Foldable Solar Panel

    What I don’t like – I don’t like using the case as the stand. It isn’t flimsy, just needs some further refinement. But it works, and as a carrying case/stand, it does ok.What I do like – Other than the case/stand, which is minimal really and not anywhere near a show stopper. I really like these panels. For 220w bifacial, they aren’t really heavy or large. Can be stowed in campers easily. I have a Rockwood A-Frame I will be using these on and they should work and stow very nicely. The panels are very well built and sturdy. I tested them in mid February here in Ohio on a sunny day. Was able to charge my EcoFlow Delta 2 from 50% to 100% in several hours running at a consistent 180-205w watts. Running 205w on 220w rated foldable solar panels in February with the low angle of the sun, that is pretty exceptional I think.I can’t answer about weather proof just yet as I haven’t had these out for an extended period of time. However based on initial testing and general use and appearance. At this point, I don’t see any issues with leaving them outside in the weather.

    Let’s talk about what you get from these for the premium price

    Update and tl;dr. My review of the performance of these panels and their cost per watt still stands, but I can understand the 4 and 5 star reviews better. The company did contact me on their own for my feedback, and worked with me to design a system that met my specifications. The higher rating of this review reflects their customer service. After working with them a bit, I do have a system that is a better value and meets my specifications. You can read this review to understand what you get from the EcoFlow panels. Overall, these panels are for anybody who has limited space and doesn’t mind the higher price tag. The integrated kickstand has worked very well for me, and this is a bonus: I don’t have to use a rigid panel or construct some wacky stand out of PVC. The whole package stows easily and the kickstand works very well (it doesn’t matter that the kickstand doesn’t perfectly angle the panels). Still, you can expect only ~65% of the rated power from these panels (other off brands mentioned here deliver ~60% based on my reading of their reviews), making these relatively expensive. Also, I did look at many of the panels available on Amazon, and found that brands such as Bluetti and GoalZero, even if they perform as well as Renogy panels (>70% efficiency), are some of the most expensive on a $/watt basis. Off-brand panels have the disadvantage poor performance (60% of rated power); you can still save money but you’ll have to carry more of them. For example, 2 Renogy 200 W panels are an excellent $/watt value if you have the space, but 2 AllPowers 200 W panels won’t deliver the same power but are cheaper. If you can work with a flexible panel (I would consider these portable, not flexible), those can be very good values but suffer from needing to be installed somewhere. So, this review I think will help inform how you go about selecting panels to meet your needs.——————————————————————————————————————The 4 and 5 star reviews are from the #vanlife crowd that wanted a good looking system, not by those who bought these as part of a system that was going to meet their needs. I live in my truck almost year round and have a system to power my computer and Starlink, as well as my fridge and phone. This is a real review.I wanted external panels because I have limited roof space, and who wants to park in the sun just to charge their system? Up top I have a 100W flexible Renogy panel glued to a piece of corrugated plastic…mainly a supplemental source of power when I don’t need a charge too bad or when I’m moving. The EcoFlow 160s were supposed to be the workhorses of my system. I got 2, connected in series with 10 ga cables to handle the amperage from these panels, feeding into a Victron 75/15 MPPT controller. I spent the extra money on the EcoFlow panels because we all know that the rated power isn’t the real-world power. I expected that a premium panel would have less exaggeration, and the integrated kickstand was a bonus. In other words, I looked past the “cheap” panels expecting them to deliver less of their rated power than the EcoFlow panels. The screenshots are the monitoring reports from the Victron controllers running the Renogy panel vs the EcoFlow panels.On days when my single Renogy panel…which I’ll remind you, is flat mounted, doesn’t get repositioned during the day to take advantage of the sun angle or avoid obstructions, and should suffer a greater heat penalty given it’s installation…that panel consistently puts out 60-80W. So 60-80% of what Renogy promised they delivered, and I’ve seen it hit >90W. That’s a $160 panel, easily hitting 75% of it’s rated power, giving me a watt of power for $2.13.On the same days, I go out and move my EcoFlow panels once mid-morning, once-late afternoon, and once in the evening to take advantage of the morning sun, changing their orientation and angle so that they are directly facing the sun and either flat (during mid-day) or angled (morning and afternoon). They have that kickstand (which for me has actually worked out okay) which helps get a good angle on the sun and should keep them cooler than a rooftop-mounted flexible panel. These panels should have a massive advantage over that Renogy panel, but I have never seen more than 208 W from a system that is rated for 320 W. That is 65% efficiency, giving me a cost per watt of $3.37. That makes these panels almost 60% more expensive for 15% less power.I’ve heard the arguments and taken them into consideration…the rated power is under optimal conditions, you’ll never see the rated power in real life, to get the rated power you need to be at 90 degrees to the sun (+/- 10 degrees), the panels won’t perform as well once they heat up, and clouds and shadows and so on. These are all true, and when you are designing a system, you have to take into account that the rated power power is the power Bob in marketing says has to be on the box because everybody else is bloating their power ratings, and anybody who used an honest real-world number wouldn’t sell a panel. EcoFlow looks to be one of the worst offenders, and I’ve gone back to my order several times to make sure I got the 160W panel and not the 110W panel. I’m also not in some oddball arctic desert place…these results hold true in Utah, Texas, New York, and everywhere in between over 2 months now. And even if I was doing something wrong, you can’t explain away the EcoFlow’s poor performance by any external factor when that Renogy panel (disadvantaged as it is by its installation) under the exact same conditions consistently and easily outperforms the EcoFlow panels every single time, every single day.I would return these if I could. Renogy has a 200W system for $349 (that includes a charge controller). Let’s say these only deliver 70% of their rated power…the cost comes out to $2.30 per watt. It’s bigger, heavier, and I’d need more panels but it is a better value. Other random but similar panels, if they performed as poorly as EcoFlow, would come in at a similar cost per watt. Dokio has a panel that appears to be similar to EcoFlow in every way except that it doesn’t have a kickstand, but comes out at a cost of $1.63 per watt if it only delivered 65% of its rated power. [Update: reading the reviews, these deliver more like 60% of their rated power.]Aside from the poor performance, I’m now really concerned about the reviews (oddly 4+ stars) questioning the durability of these expensive panels. When I go to move them, yeah, they are hot. Like, wear gloves hot. And you hear the panels cracking and creaking in ways that say maybe these aren’t going to hold up too well. How long until they crack or become unbonded, delivering another hit to their already weak performance? Again, that Dokio panel or a set of Renogy panels are looking more and more like a better value.When you’re looking at the Victron reports, yes, the EcoFlow panels deliver more total power…keep in mind they are moved several times so they see the sun at a better angle for the entire day; the Renogy panel maybe only gets a good angle on the sun for a few hours when the sun is almost directly overhead.Also, FWIW, this review is based on my personal experience. EcoFlow did contact me and did not offer any technical support, but did provide some incentives to bring my system up to the performance I expected.

    Lighter, cheaper, more efficient than Goal Zero Nomad 200. MUST for high-capacity batteries

    Over a year ago, I purchased the Goal Zero Nomad 200 for its large-capacity, 4-pane solar panel that folded down to a 1/4 of its full size. That made it relatively compact, though at 22 lbs it was not exactly lightweight. Where it stood out was its 200W of monocrystalline charging capacity, and when used in combination with other Nomads (or the company’s more rigid Boulder panels), quite a large amount of electricity could be produced to quickly charge a battery power station with, such as the Goal Zero Yeti 1500x that can take a whopping 600W!I had been a fan of Goal Zero’s products for a few years now, but recently, one of my good Boondocking friends asked me to take a look at the EcoFlow Delta Pro power station for our mountain vacation home. That monster was so packed with features, it literally left me in awe and quickly added the company to the top of my favorite power station brands alongside Goal Zero and Jackery. Fast-forward two months later, and I thought to also take a look at something interesting: “Bifacial solar panel”. What the heck is that?BIFACIAL SOLAR PANELUp until recently, all of the solar panels I had tested were monofacial — that is, only ONE face captured the sun’s energy while the other side did not. Bifacial covers a panel with cells on BOTH faces (front and back) to maximize solar energy production AND use up less space, but tends to cost more than the 1-sided products. Imagine my surprise when EcoFlow’s 220W Bifacial Solar Panel only costed $50 more than than Goal Zero’s monofacial Nomad 200… So, how did both compare?ANALYSISEcoFlow’s 220W Bifacial Solar Panel amazed me in a number of ways. According to the marketing material, the front-facing side could produce up to 220W of energy and the back up to 155W for a total of 375W. Reality was nowhere close to that: the most I was able to capture in testing was 198W on a bright, sunny, California day on white-painted surfaces and a MPPT controller-equipped Goal Zero Yeti 1500x. The EcoFlow Delta Pro only reached 184W a few minutes prior. Are those numbers good? Yes, absolutely!Monocrystalline solar panels generally lose about 20-25% of efficiency from their stated rating due to loss from solar conversion. The EcoFlow 220W’s front face would, therefore, produce only up to 176W on a perfect, sunny day. Yet, my tests captured as much as 198W — where did that extra 22W come from? Its 155W backside through sunlight reflected by the ground and surrounding area. The back face actually captured roughly 14% of its capacity! Moving the panel to my grassy backyard, however, did not add much: a mere 5W-10W.Was the small increase worth it? That depends. Any additional amount of power can make a difference in certain situations and living arrangements, especially when one was in the middle of nowhere. Whether that augmentation is worth any extra cost, however, is not black and white. The question ultimately comes down to how much the back side could consistently add to the total output, and that, my friend, depends on the surface and surrounding area.The more sunlight is reflected, the more the backside of bifacial solar panels can capture, though it could never reach the 75-80% efficiency the front face would. A dark, non-reflective area would hardly give any extra watts, but a mirrored room would produce a lot more — especially one that had concave reflectors aimed squarely at the back panels without burning a hole through them. A 22W increase required me to place the panels on and in an area covered in bright white to maximize the amount of reflected sunlight. That kind of exposure is not something I normally come across in my travels, like camp grounds or forests. Even rocky places like Yosemite National Park that is dominated by granite would not provide that reflective power unless the panels were deployed on snow. Alas, if there is snow, the sun is not as strong as in the summer, but that is precisely where bifacial solar panels could make a small amount of difference.CAUTION: Never leave the power station out in the sun! Keep it shaded to minimize the risk of overheating AND use a long cable to connect it to the solar panel.Power aside, the EcoFlow 220W costs nearly the same as the Goal Zero Nomad 200W, but has that additional 155W backside panel thrown in. That makes the EcoFlow a better deal purely from the amount of potential power produced. It also weighs about 1 lb less for nearly the same, overall dimensions.Where the EcoFlow stands out is its IP68 water rating that allows it to be submerged in 5′ (1.5m) of freshwater for up to 30 minutes. That means that water could be spilled on it without any damage. It could theoretically also be used in rain, but that idea sounds absolutely ridiculous: does the sun shine strong enough, if at all, in that kind of weather to make any difference? Still, not many consumer manufacturers offer IP68 waterproofing.Both the Goal Zero Nomad 200 and the EcoFlow 220W are coated with tempered glass for better protection against the elements, but the latter uses the MC4 solar cable type connection. I much prefer the Anderson Power Pole (APP) port over MC4 for its ease-of-use, but do not fret: there are adapter cables available that convert between both types. My favorite, lower-cost brand of adapters is iGreely. What this also means is that this EcoFlow solar panel CAN be used with other manufacturers’ power stations, including Jackery, Goal Zero, and Bluetti. Check their manuals for maximum input specifications.CAUTION: You should almost NEVER connect multiple solar panels to a battery in series. I generally recommend having them plugged in parallel.Kickstands were built-in to both EcoFlow and Goal Zero solar panels, though the former took a bit longer to set up. Its design reminded me of tablet cases that flip their cover back to prop up the device. Both allowed the panels to be angled at an optimal 45 degrees towards the sun, but neither of them could withstand strong gusts of winds without securing them down.Multiple grommet holes could be found around the edges of both manufacturers’ solar panels to accommodate a variety of mounting configurations like off the side of a truck or on rope.Overall, the ability to get up to an actual 198W of solar charging from a single product made the EcoFlow panel portable and convenient, though its 21lb weight could feel a bit heavy to lug around. It took about the same space as a 100W Jackery SolarSaga 100 and the Goal Zero Nomad 200. For charging a high-capacity battery like the EcoFlow Delta Pro (3,600Wh) or Goal Zero Yeti 1500x, however, the EcoFlow 220W Bifacial Solar Panel is an absolute must if you want to maximize its input capability.Note: Goal Zero renamed its Anderson Powerpole (APP) ports in Nov 2020 to High Power Port (HPP) to avoid trademark infringement with its inventor: Anderson Power Products. This is only a name change as the connector works the same way as before. For the purpose of avoiding confusion, I will interchangeably refer to the port as HPP or APP.PROS- Bifacial panels to allow 5-25% additional energy production- Monocrystalline solar panels provide VERY efficient charging at a consumer-friendly price point– Most panels should expect between 70-80% charging of the stated wattage in near-perfect, sunny conditions– Monocrystalline generally has a lifespan of 25-30 years, after which efficiency starts to drop- Large-capacity solar charging of 220W (plus up to 40W extra from the backpanels) in a single product negates the need to bring two 100W solar panels– Can provide higher maximum charging output to compatible battery power stations— Example: Goal Zero Yeti 1500x power station can take 4 solar panels with a HPP-to-HPP 4x Combiner Cable—- Keeping in mind that there is a roughly 20% solar conversion efficiency loss and that power stations can accept a limited number of panels:—– (4) 200W panels = 640W (4 x 200W – 20%). Provides full 600W power to Yeti 1500x—– (4) 100W panels = 320W (4 x 100W – 20%). Does not maximize Yeti 1500x’s charging capability– Saves on storage space to have a single product instead of two– Faster to set up and put away than with multiple solar panels- Foldable design makes the panel portable/compact, easy to stow, and protected from dust- Excellent pricing and value– Costs slightly more than two Jackery SolarSaga 100 (to get 200W) or Goal Zero Nomad 200- Built-in kickstand (via its briefcase) to help prop the panels towards the sun at a 45 degree angle for optimal exposure- Multiple grommet loops around the edges accommodate a variety of mounting configurations– Side of truck, along a rope, etc.- IP68 waterproof rating for brief, 30-minute submersion in up to 5′ of freshwater or rain- Tempered glass layering makes solar panels stronger- Weight: 21 lbs– Lighter than Goal Zero’s Boulder 200 (42 lbs) panels, but similar to the Nomad 200 (22 lbs)– Heavier than TWO (to get 200W) Jackery SolarSaga 100 (5.5 lbs each)- Daisy-chainable– Multiple solar panels can be linked together in PARALLEL (NOT in a SERIES) for even more output (See TIPS section)CONS- Back side of panels heavily depend on the amount of sunlight REFLECTED by the surrounding area to be useful– A dark, non-reflective surface or environment will hardly add any extra power, for example- Sometimes frustrating to set up on sand (ie. beach)– Common issue with foldable solar panels- Potentially a single point of failure– Example: One 220W vs two 100W panels— If the 220W fails, you are left with no solar charging. If one of the 100W fails, you still have the second to charge with- Weight: 21 lbs– Heavier than 2 Jackery SolarSaga 100 (5.5 lbs each) for the similar 200W output- Flexible body can potentially cause the panels to snap and break- More expensive than:– Lesser known brands, such as Rockpals/Paxcess and Suaoki– Non-foldable, rigid panels like Goal Zero Boulder 200 and Renogy- No built-in USB-C or USB-C PD (Power Delivery) charging port, but that is also what makes the panels IP68 waterproof- No built-in battery to store some of the charge generated by the panelTIPS/NOTES- Panel lifespan: Panels generally die/become inefficient between 25-30 years– They may last longer, but would produce less energy- Solar panels work best outdoor under full sun exposure– Although the panels will work under the shade or behind windows, charging efficiency is greatly diminished— That is ESPECIALLY true for the backside of bifacial solar panels– Panels will STILL charge under cloudy conditions. So, keep the panels out even if you do not see the sun– Operating temperature range: 14F to 149F (-10C to 65C)– ONLY the solar panels can (and should) be directly under the sun while charging a battery power station— Keep the power station in the shade to prevent overheating- ALL panels must be uncovered to generate a charge– Do not completely cover one or more panels or the charging will stop- To maintain solar efficiency, the panels should be kept clean– Remove dust with a soft brush and wipe with a damp (NOT wet) cloth– Any residue, such as tree sap, should be removed as soon as possible– Do not submerge the panel under water even though it is capable of doing so for up to 30 minutes in 5′ of depth– Panels will work longer if they are kept away from water altogether- Do NOT bend the panels more than 30 degrees or risk breaking them!- Keep the panels away from fire and heatersSOLAR PANEL – WARNINGSome power stations can be charged with one or more solar panels. There are SOME PRECAUTIONS you must take to minimize battery damage and/or injury to life/property:- Never exceed the maximum Voltage (V) or Amperage (A) of a power station’s charging port- If you want to use 2+ solar panels to charge faster:– Do not mix them with different V or A as the output might get reduced (less energy generated)– Do not daisy-chain them in sequence/series as that can exceed the power station’s maximum V or A— Always connect them in PARALLEL with a Y-branch or Combiner cableCALCULATIONSThe below calculations are rough ESTIMATES as conditions, battery and solar panel quality, and age can vary. Battery storage capacity is measured in Wh, and power output is in W (Watts).CHARGE TIME WITH SOLAR- Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])– In a perfect lab environment, solar panels charge at the listed wattage– Expect to only receive 50-75% on a good, sunny day (ie. 75W – 113W for a 150W panel), depending on panel’s age, component quality, and weather- 200W solar panel– EcoFlow Delta Pro: As fast as 13.5 hours [3600Wh / 200W x 0.75)]– Goal Zero Yeti 1500x: As fast as 10.1 hours [1516 Wh / (200W x 0.75)]– Goal Zero Yeti 500x: As fast as 3.4 hours [505 Wh / (200W x 0.75)]– Jackery Explorer 1000: As fast as 6.7 hours [1000 Wh / (200W x 0.75)]- Tips– Keep charging even when overcast as the panels will STILL collect energy– Underproduction: If a 200W panel is not making enough (ie. only 50W) due to bad conditions, adding extra ones (ie. two more 200W) can generate a higher, combined output (ie. 50W + 110W from the two panels = 160W total)– Overproduction: If the panels make more (ie. 400W) than the maximum the power station charge port can take (ie. 120W), only the max (ie. 120W) will go throughWATTS USED/PRODUCED BY A DEVICE- Calc: Watts used or produced by device = Voltage x Amperage- Vacuum with 120V @ 9.5A uses 1,140W- Solar panel with 12V @ 10A can produce up to 120WTIME TO CHARGE A DEVICE- Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage- Laptop with 200Wh battery, 200W solar panel, and 75% solar conversion loss: As fast as 1.4 hrs [200 Wh / (200W x 0.75)]USE WITH OTHER BRANDSThe EcoFlow 220W solar panel can be used with other manufacturers’ power stations, including Jackery, Goal Zero, and Bluetti, as long as their rated input are not exceeded, and the appropriate adapter cable is used (ie. MC4-to-APP or MC4-to-8mm).DIFFERENT SOLAR PANELSAs long as the solar panels from different brands or wattage produce the same VOLTAGE, you will be able to safely use them together. The key here is to connect them in PARALLEL. If the panels are NOT the same voltage, then the panel with the highest volts will be used. For example, I was able to connect these four panels with the Goal Zero Yeti 1500x:- Goal Zero Nomad 200 / Jackery SolarSaga 100W / Paxcess Rockman 120W / Suaoki 160WOn a cloudy November day, the input values were:- 63W = Nomad only- 212W = Nomad + SolarSaga- 231W = Nomad + SolarSaga + Rockman- 262W = Nomad + SolarSaga + Rockman + SuaokiI expected the panels to produce significantly more during the summer (to as much as 430W combined), though I never repeated the test.CONCLUSIONThe EcoFlow 220W Bifacial Solar Panel sparked my curiosity on how much better output a second set of panels built into a single product could provide. It did not wow me and required a specific, reflection-optimized environment to add any meaningful energy to the primary, front-facing panels. However, I still came away impressed because it had the potential to increase solar output for nearly the same price as Goal Zero’s Nomad 200 or two Jackery SolarSaga 100.Higher-capacity solar panels like this EcoFlow are essential to charging large power stations (like the EcoFlow Delta Pro or Max, Goal Zero Yeti 1500x, or Jackery Explorer 1000), especially if those batteries only accept a limited number of connected panels. The foldable design allows it to be set up and put away quickly and uses up a much smaller amount of space than rigid panels that are meant to be permanently mounted. However, it also makes it more susceptible to damage if the panels are bent at an angle of more than 30 degrees.Overall, I was very impressed by the solar charging efficiency the EcoFlow 220W provided to both the EcoFlow Delta Pro and Goal Zero Yeti 1500x batteries. The panel’s 155W backside — when deployed in an ideal environment — is a welcome icing on the cake to provide just a little extra charging juice for the traveler or home prepper.

    Great panel

    Very easy to setup and use. Works well and charges my ecoflow river in about 3 hrs of good sunshine. I think the case as a tripod to position the angle of the panels could be tweaked a little bit, but once I became accustomed to the way the case hooks to the panels, it became easier. I highly recommend this panel

    it’s okay

    first. everyone keeps saying.there was no cable for the panel. it was included in the packaging.2nd. it’s heavier than you think3rd. it needs a better kickstand for portability and adjustability. the fact that you have to angle to where you get most sunlight. using the carry on bag is not ideal.4th. I had 34% left of power and started charging the at around 12 pm. sometime around 5pm it reached 85% of battery. slow but it work.my only gripe is the lack of a good kickstand.

    Durable high output portable panels

    They seem to be very well constructed and have been working well to keep my delta pro ultra charged up nicely. They appear to over perform the 400 watts they are rated for. My only recommendation to EcoFlow would be to add some sort of structural support to help keep them straight in line. Such as something like fiberglass tent poles.

    200+ watts without trying! Also great self storage.

    I love that this panel is portable and looks great. Without carefully arranging at angle to the sun I’m getting 230 watts input power for my Delta Pro. Connecting this with my fixed panels will help prepare me for next summers blackouts.

    Let me tell you what EcoFlow Does Not

    I was very excited to have this item as part of my gear! When I first received it and tested prior to my trip, I was slightly impressed. The stand is garbage. The panel is VERY heavy. No insulation. However, I did see about 360w of input power on my Delta. While I was still 40w short of the max – I was still OK w/ it. However, after I packed it up and took it to the music festival – the MAX I gained was about 250-260W. Full sun. I hit up EcoFlow support and they wanted this and that, which was unavailable to me in the field. Once I returned back home, I reopened the support issue. Support informed me the panels can reach ~140 degrees F – and if it does so, the efficiency decreases by ~13%. This would have been AWESOME to know ahead of time. Instead, I found out the hard way. The panels got so hot, they melted the paint on my car! The stand was garbage, as it is very thin compared to the expanse of the panels, so I had to use a larger stationary item to prop them up and point at the sun. And welp, the panels got so hot (from the awesome sun they received), it legit MELTED my paint job – which was factory, not custom. My friend and I also burnt our fingertips / hand in attempts to keep it adjusted at 90 degrees to the sun. All of this effort, damage and injury – yet we saw a MAX of 260W input to the Delta 1300W system.Needless to say- none of these details were documented ANYWHERE. There are no user manuals or WARNINGs available. This information was attained ONLY AFTER contacting support!!!!!! I am reaching out to lawyers at this time to see how to get right due to these negligent circumstances.Also, worthy of note – my friends and other nearby campers had the Jackery system. While the charge time is greater, they all did BETTER than me keeping their systems charged and running over the 5 days. Also, the Jackery panels were insulated so you could move them without burning your hands. After this experience, I am totally good w/ a longer charging time that comes at the expense of my other possessions as well as my health.Bottom line: look elsewhere if you desire something to keep you going off the grid. If I could get by w/ AC only, this would be the move, as the solar panels are not needed. But.. if you want to go off grid – go elsewhere!!Also good to note – EVERY MODEL except the DELTA can be monitored via an app on Apple/Android…Update 7-3-2022 – after informing support of the heat issue, they asked me to return the panel back to them directly for investigation. Not sure where this will go, if anywhere, but at least they have shown an interest in the root cause of their product.Update 7-14-2022: I rcvd a different panel by allpower (200w 18v prime day spcl). Multimeter showed good output around at least 180w. Delta would not show more than 110w input. I hit up support w the info on the same thread. Wondering if their 400w panel was defective and blew the mppt controller in the delta unit. More to come.7-20-2022: I heard back from support. The solar panel was certainly defective. They offered to refund my Delta purchase. Decided to return the Delta b/c I do not trust it w/ the ancillary testing. Will likely go with a more reliable unit. I initially selected EcoFlow for the rapid wall charging capabilities combined with the high solar input feature. I mean, they had GREAT reviews, too! They declined to do anything about the damage to the paint on my vehicle, stating the operating temp is 70 C (~150F). Personally, I would not go outside in that heat. Humid 115 is challenging enough for me!I know this is likely an isolated incident – candidly, my luck is generally horrible. In short, the products let me down in the field and caused me more headaches and stuff to repair. BUT(ish), the company refunded the initial purchase price. Take it as you will and happy hunting for fun gear!

    I purchased the Ecoflow Max generator and 160W solar panel after exhaustive research because I am in Florida and hurricane season is underway. As an elderly woman living alone, I did not want a conventional fuel generator for a variety of reasons.There are several manufacturers in this solar battery market to choose from. I am writing this to reassure those who, like me, mourn the loss of active and effective after-purchase support in the form of Customer Service. I went in with low expectations in that regard. But, I have experienced a Customer Service Miracle! I experienced a problem with the connector cable to the solar panel. Heaving a sigh of disappointment, I hit the SUPPORT button and mentally prepared for the usual canned response.Was I in for a surprise!! Response from Ecoflow was immediate and focused to my problem and asked for more detailed info/short vid etc. I returned the information and Ecoflow promptly stated it would send a replacement cable. And, it did! However, that did not really solve the problem, so the conversation was continued.This review is intended to reassure potential purchasers that the the support process has been orderly and pertinent to resolving my problem. Early on, I developed confidence that Ecoflow would follow through and accommodate me until satisfactory resolution was reached. Ecoflow even accommodated my special request to send the replacement product AHEAD of the return due to the hurricane season and necessity to have a solar panel on hand. This is the mark of a reasonable and responsive company and is a modern day miracle!It is rare these days to have Customer Service give focused attention to difficulties whether they be technical or also arise from a personal situation (like my being an old lady living in the boonies and have some limitations). Based on my experience, purchasers should feel reassured to know that Ecoflow has an excellent customer support process and demonstrably holds its customers in high regard.

    Update on Cracked glass panel

    8/29/23 Update: Ecoflow reached out to me upon seeing my review on Amazon. Without any argument, they quickly agreed to process a full refund! I own an Ecoflow River 2 Pro and am very happy with their products. I especially love their customer service. They go above and beyond. I would have been happy with a replacement but I’m a weak 70yo and discovered the panel is too heavy for me. I will buy a lighter panel from Ecoflow as soon as I figure out the best configuration for my situation. Thank you Ecoflow. I just returned from a camping trip. Only used the panel 3X because I was on the road so much. The glass on one of the panels cracked. I never laid items on it. The panel sat upright the entire trip. Also, the case provides very little support. Needs strong kickstands. The glass crack is only on one panel but it stretches the full width. Ecoflow’s customer service was really outstanding when I first purchased the panel. I’m now hoping for an exchange because I actually do want the panel. Also, maybe they have ideas on how to improve the stand because it really is too weak for such a large panel.

    Very useful and integral piece…..

    The compact design and portability of this panel , with its efficiency so far has given me a very positive outlook towards building my solar energy network. During the fall peak hours of sunlight I am achieving 350-360 watts input to my Delta Pro generator. Once I am able to complete my stand I expect that I could achieve a slightly higher result. I’m quite encouraged so far with the portability and efficiency of this panel.

    These CRANK wattage!

    Hook up a couple of these panels for some SERIOUS charging power.EcoFlow back their products too!

    Failing to charge when the sky is overcast.

    Cannot cannot charge when the sky is overcast. No input watts when there is no direct solar beam.

    Inspect your panels *Update* Seller/Amazon quick to send replacement

    *Update*The replacement process went smoothly and I recieved a replacement panel quickly without issue. My new panel looked great, so I’m changing my rating up to 5 stars for seller/amazon responsiveness and the fact that the damaged label seems like a one-off defect. Still, make sure to closely inspect your panel when you get it so you can get a new one if there’s an issue :)-Original Review-Upon opening the box, which was not damaged, and setting up the panel to test it outside, I noticed a pretty big scratch marring the surface of one of the panels. I’m not sure whether the scratch is affecting the power generating abilities of the solar panel, but even if it’s functioning correctly, I’ve ultimately decided to return it in case the scratch affects something else like weatherproofing.I’m giving this product a preliminary review of 3 stars because it arrived damaged. It did come nicely packaged, so it seems like the panel was damaged prior to shipping, but who knows for sure.I’ll be happy to update the review with my experience with the return/replacement and when I receive a new one and have the chance to confirm it works.

    Good performance ruined by poor choice of materials

    ————- Update #3 ———I have used it only twice. One time for testing on my deck. And one time for a one night popup trailer camping. The zipper does not work anymore in two areas. For the overall price, I cannot believe that they use such low quality zippers.The panels work. I was able to generate 300W at 4pm in a sunny day in Northern New Mexico.But how do you store the panels without the bag closing?————- Update 2 weeks later ———I tested this 400W panels for one week, and found some weird issues. The panels were left outside in NM. About 90F during the day and mid 50s F at night.They did work to deliver enough power to keep a small fridge running 24/7.However, as I mentioned before, the 2 panels on the side collapsed instead of staying straight. More like a tent. Power was reduced as a result of a less optimal angle.When I decided to stop the experiment, it was about 55F outside in the morning. I could not correctly fold the panels! The ‘hinges’ were too stiff. I left the panels under the sun for about 3 hours to warm them up so I could close them. It would have been a pain if camping.Worse, the zipper is not a very good quality. This is the first time I tried to close the bag and I could already see some problems with the zipper! One would expect a much better quality for this price.Also I see that they changed the pictures on the Amazon site. Initially it was misleading as a hiker was casually carrying both a Delta 2 and the 400W panels. This is a heavy set. Good that they changed the pictures.Finally, the seller is proposing that I send it back. But this is not a simple return to a UPS drop location. You have to wrap it for dangerous components and go through a FedEx appointment. Far from trivial from where I live.————- Original Post ————-Bought it to charge a Delta 2.Pros: It does the job. Here in NM I can charge from 70% (after keeping a small fridge powered all night) to 100% by 10:30am.Cons:- The picture shows a causal hiker carrying a Delta 2 and the solar array. That’s misleading. I guess he does that for just a couple of minutes. The set is heavy!- The pictures are also showing neat straight aligned panels. In reality, the panels cannot be aligned without something else (rope, support). My array looks more like a tent. Meaning that some of the panels are not optimally aligned with the Sun, wasting some energy.- The bag seems too pretty to lay on the dirt. We will see if that is a mud magnet or if it is washable.- The Delta 2 app UI scared me at first. it was showing 0 watts from the panels once the battery is fully charged. I thought that something was wrong. It is just that the battery does not get charged once it reaches 100% until it drops to ~98%. I guess that it makes sense to not charge anymore when the battery is full. But there is no difference in the UI between not charging and the panels not connected (or not functioning).- I think that there is a bug for the end of a sun day. I mean that if the battery starts to be below 98%, it will attempt to charge from the solar source. But at the end of a day, there is only little to no power. The battery keeps trying to turn on charging. There is then a beep every few minutes/seconds. I had to disable the beep from the app to go around that.

    Terrible customer service!! UPDATED REVIEW OF SOLAR PANELS OCTOBER 15, 2023

    December 9, 2023. UPDATE.I am changing my rating on this panel because the customer service in EcoFlow is atrocious !!!! I have written and called about getting a carrier case for my bifacial solar panel since the carrier case zipper is broken and will not close. I have been waiting since July to get this issue taken care of and I still do not have a case. I receive a solar panel box thinking it was the case and upon opening it up the box is empty. Why am I getting empty boxes. EcoFlow I want my carrying case, please see to this. With all the brilliant minds you have there you would think they could solve a simple Issue.I recommend that if you are in the market for a solar panel do not buy from EcoFlow. Buy the one from BougeRv, and they have better customer service if you need it.In July I purchased 2 bi-facial folding panels from ecoflow and was quite disappointed and frustrated that some one in their warehouse would actually go through the trouble of packing and expensive product in a box knowing that the carry case for the solar panel is unserviceable.The zipper is broken but what they did is put the solar panel in the box and then they placed the carry case around the solar panel like a blanket. Why on earth would they just not get another carry case that works or better yet another solar panel with the carry case. How am I to transport it without the carry case. This is a fragile panel and the carry case protects it from damage.Ecoflow makes good products but when it comes to this company I have the worst luck ever. In the past they sent me an expansion battery that would not pair up and their reply was that they had not had time to test it. Then why send it. All they care about is selling the product and then dealing with you later.I have emailed them several times and have called and they have assured me that they would take care of my carry case and they would send me a new one. Now they have stopped responding to me and it is now September and I still do not have a carry case.I will not review how the other solar panel works until they get their act together. I definitely won’t be buying the Ecoflow Pro now.Beware of their customer service if you decide to buy their products.UPDATED OCTOBER 15 2023.This review is about the solar panels themselves. Bought 2 of them to charge my 2 Delta max 2000’s, and my River Pro. Yes I love ECOFlow Products but am not pleased with their Customer Service, but at the end they always deliver and do make things right …ALWAYS!The two solar panels worked great, I was able to average 324 watts of input with the panels lying flat on the grass and not facing the sun at the optimal angle. I don’t recommend you ly them on the grass it burned the area they laid on but than temps here in Texas were averaging above triple digits for 75 days. Today they both produced 378 watts out connected in series. I definitely recommend the 220 bifacial solar panels or the 160 watt panels of which I own 2 as well. Like I said I love ecoflow products and they are a great addition to the other power banks I own before Ecoflow came into the market, they are just better.
