  • Make triple sure the charge controller you buy will work with the output voltage & amperage.
These panels were slightly larger, yet lighter, than I imagined. The unfolding and folding is a snap, though a tiny bit cumbersome due to size. Not a big deal and well worth the effort for the output. The panels have "emergency use only" printed on them, guessing for a CYA just in case. Not sure if that means it will not last long and is a temporary replacement, or what. Given the often outlandish marketing on chinese products, it's really hard to know or trust. At the price, I'm not willing to find out through longevity testing, as an unsponsored person paying out of pocket for SHTF gear. I had to separately purchase an adapter to convert the connectors to SAE so that I could use a charge controller and other devices. BEWARE: lower end controllers can NOT handle the 37V these panels can push. Make sure whichever controller you buy can handle the outputs. I ended up having to purchase the "Renogy Rover 20A 12V/24V Auto DC Input MPPT Solar Charge Controller" which can handle these panels. ... show more

  • Great unit and well powered
I've added this to supplement the solar I have on the roof of my RV and also to charge my golf cart. Unfortunately when camping you can't always find spots fully in the sun (and who wants to honestly with the summer heat??) but that doesn't lend itself well to recharging your battery bank. I purchased two different charge controllers - one 20A unit to charge the battery bank in the RV (you can't just combine this solar panel into your existing panel's controller due to mismatch in voltages and amperages - do your research what will work for your circumstances of course) and another up voltage controller to charge a 48 Volt golf cart battery pack. Used XT60 connectors and extension cables and I can easily move this panel between the two different systems. Couldn't be happier with these panels. No, they are not "light" but are easily handled and have great output in good sun. Highly recommend!! ... show more

  • Full disclaimer, I’ve only had this for ~36 hours…BUT WOW
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! ... show more
