Needs better legs.

These do work well, and I'm happy with the purchase. However, they are quite heavy, understandably, but as a word of warning. Two of the elastic leg straps have ripped from the back, it doesn't affect the stand, but they're not attached very well. Also, the latches that hold them closed are fairly brittle, they can break easily if you're not careful.Overall, nice panel, provide a lot of power, just a few construction issues.

Edit: 6 months later…I’ve had it for around 6 months and it’s worked well when I’ve used it. I’m still very worried about its longevity - roof mounted panels will last years and years without so much as a scratch…this thing as it’s put up and taken down often…it may last 2 years tops. It is very heavy too. I carry it with one hand but wouldn’t trust most of my family to be able to.I see bubbling under some of the solar modules, and I’m sure it’s effecting performance. Now in full sun I’m lucky to get 300w typically.I will say as far as technical support and warranty are concerned - they sent me a replacement VERY quick after discovering that something shorted out on my panel. The voltage dropped at that time to 1v, but was still existing so it wasn’t an open circuit….ive actually fixed that panel by cutting it all open and replaced a diode and it’s working just as well (but more bubbling under the modules, so I expect it’s just an age thing)Original post:So far, amazing.I have this plugged into a set of homemade extensions (16ga CCA wire) followed by a set of 20ft extensions purchased on Amazon and delivered yesterday - into a bluetti AC200 MAX’s solar input.First day of original setup, I was getting 40-60w while terribly overcast at 5pm, so the sun was super low and ridiculously covered.The second day (full day of high sun, but also ridiculously overcast, picture of said sun and clouds) I was pulling a solid 130w all day long. Not bad considering (funny enough a Solar prediction app I have suggested I’d make so little with the weather that day that it would hardly offset the bluetti operating wattage….it was far exceeding that)TODAY is a sunny day, and so far today I pulled 397 watts for a few minutes…altogether it’s partly cloudy now, so I’ll watch it hit 390 then simmer to 130 or so (I’d say on my setup the 130-150 is about baseline that I can always expect to hit)It’s setup in the yard, pointed directly at the sun, but the wattage peaked to where I wanted it to for sure.Cons:So far it feels fragile…more fragile than I care to admit. This may be a solar suitcase, but these are NOT flexible panels, so if you were to have them drop on something while carrying to setup, you will likely damage them? Not sure, don’t want to find out. Be careful with them. (I’m knocking a star down on portability only for this reason, but it’s almost to be expected this thing is big and fragile)Because of the sheer size and weight, this means the wind can easily take this thing and flip it/flatten it. If so, be careful about what you put underneath it or around it as well as the terrain it’s on. (There are nice little loops to secure it to something if you wish to do so on the top and bottom between the panels)Altogether I got this for a really good deal with discounts and promotions and am EXTREMELY happy with its performance. I full time in an RV, and had yet to get Solar and while I’m building out a legit rooftop array, I purchased this so at least I’m making some production and offset my ‘always on electronics’.This will easily stay in my arsenal and probably purchase a second because the bluetti can take in quite a few more watts of Solar and this thing is worth it that’s for sure.I’ll update after some time owning it for longevity sake!

So, I have a couple of these and they are just ok, heavy, handle is horrible, and the last one I just got would not produce over 300watts. That’s 75% efficiency and that’s not good (actually that’s horrible). Had a prefect clear sunny day with a perfect angle and right @ peak solar. 300 watts is all I could get out of it. I’m in southern Utah and all my other panels are getting well over 85%. Look on the bright side they did send me a couple carabiners with this panel. Not buying any more and they also showed up two days late, but USPS is a whole different review.Follow up! Only used these for a limited time and had them outside for a week and they both started to bubble and melt the plastic. Emailed service, crickets no reply back. These panels have a two year warranty but after reading they want you to send them back at your expense then file a warranty claim. No way I am sending these back on my dime (very heavy). Zero is my rating now and I will never buy or return these. The ones I have are a fire hazard in my opinion and I’m probably out 800 bucks. So there are the facts of my panels, hope you have better luck than me.Update: support finally contacted me and told me the panel is only warranted for 1 year and it’s not covered under their warranty. I told them according to the listing the warranty is 24 months. No reply. Im so done with this company, the panel is going in the trash, I can’t deal with these people that can’t even honor their listing or their product. Horrible! Not worth my time.Update: support emailed me and stated they are sending a new panel and cannot refund. I really don’t trust these panels and when it arrives I’ll be selling it or giving it way.

Love this solar panel array! Works perfect!

First and foremost, this thing is HEAVY. It's not recommended for a bit of a long walk as I'll put a toll on you. I would carry this around really short distances. Now that's out of the way. This is my first solar panel. I'm using it for my bluetti AC180 battery. There haven't been many sunny days since I bought it The one day that it was sunny. I tried it out and I got 340 watts out of it which is really good. Since this is a heavy solar panel, it was also not easy to open it up by myself. This is not for a picnic or an evening at the park. I haven't done real life testing yet. Waiting for the summer but will update if any issues come up.

Finally had a chance to use it. After a failed trip to Arizona for the winter it’s spring and plugged it in to my Anker 767 and it’s producing 325-372 watts in good April sunshine here in Alberta. Clouds or shadows do definitely drop the wattage just like all panels.It is a bit cumbersome to setup and move around but what can you expect for 400 watts.I would buy it again and am things about adding the 200 watt panel also. Longevity is an unknown but with some care we will see. Also, heat does diminish the efficiency somewhat as well. Initially set it up today a 8C with 363 watts and now it’s 19C and wattage is 346. Still pretty good in my books. Hope this helps others looking at purchase.

With this panel you get a poor quality panel ith lower than average charge rates coupled with per my experience it not even taking a minor sprinkling of rain and customer service that was horrendous when I contacted them. You get what you pay for, it's a cheap panel at a cheap price with overblown performance ratings and bad service (almost like they weren't surprised and have this happen often that they are now just a bunch of angry people). BUYER BE WARE - STEER CLEAR

Panel is great and came in good packaging. Super heavy to move around and the legs don't have much stretching capability. I would have given this a definite 5 stars for the power and portability. The delivery guy dropped it to a different residence and it was just a hassle to get it back as it's super heavy and I had few more items arriving on the same day. This is the first Amazon delivery in 8 years that was dropped off to a different suite altogether! Seller is great and item arrived on time as expected. Will update the review on the performance since it was an overcast day.Review after 3 months: panel works great even in low light but the output is not more than 50 watts on full overcast day. Buy this if it's on sale!
