XINPUGUANG Foldable Solar Panel 200W 12V Portable Solar Charger with 20A Charge Controller for Battery Power Station Camping Travel RV Van Outdoor

It would be good if it had a stand, since I have it leaning against a wall! I have had this Panel outdoors since 2021in Rain Wind and Hot Sunshine! The Wind has even blown the panel down, so that the Plug has pulled out, and I had to secure it with zip ties! The fabric has even ripped from the wind, and I just applied some strong adhesive to repair it! I've even secured it with nylon fishing line tied to Rocks to keep it from blowing down! Despite the Rough Treatment this Panel has been through it continues to perform at its Maximum at full Sunlight!

This kit is set up for you to bring your battery to it, the longest cable is 5 feet and connects to the battery. I wanted to install it in my RV and have a cord long enough to move the panels around outside to find sun. I mounted the controller inside the trailer above the battery and connected it using the supplied battery cable except I cut off the connector and put ring connectors on the ends to permanently attach it to the battery. I made my own extension cord using the connectors the came in the kit. Now I can attach the solar panels to the installation in the RV and move them around to catch the sun outside. My 20 foot extension cable fits nicely in the pouch on the outside of the folded up panels. I like the material for the case, it's like canvas but made of nylon. The instructions for operating the controller are kind of cryptic, but I eventually figured them out. Overall a nice kit, just figure you will need to make an extension cord if you want to use it like I am.

There are a bunch of cables, but no SAE plug for shore power plugs. At least there is MC4, but why not both and loose the very odd other ones. Plus some of the lines are very thin gauge. Easy to replace, but why?

I'm getting about 150w on a hot clear day. Not too bad, on a cold day it should hit ~175w.

I have 2x 200w sets of panels. I use them in series to charge a 24v battery in my RV through an MPPT charge controller.The bad:Nothing really, although I do worry about durability. The flexible panels are a bit fragile, and you have to be careful not to break them or move them from a corner.There are some wires going through a hole in the back of the nylon case. It does not inspire confidence. It would be nice if they included some type of strain relief. I can see how an accidental trip over the cables will rip them right off the panel. I'll need to sew the connector to the fabric so it doesn't pull on the wires.The meh:The accessories are meh. The PWM controller this comes with is cheap. I verified they worked, and then immediately tossed them aside to replace it with a MPPT controller.The wire gauge of the accessories is pretty small. Not bad for such short runs, but it'd be nice to have something a bit beefier.You'll really need to have something to put them on -- at a minimum to keep it from blowing away in the wind, and at most to keep them pointed at the sun. It's nice they have the grommets on the side to attach rope/bungee cords. I plan on building a foldable PVC frame to hook them to.The good:I haven't had them for too long, but they perform well. I connected the 2 in series, and the MPPT controller keeps them right around 40v when they're working.During a cold day in mid-December, I was getting around 300w (peaking at about 350w) out of the 400w of panels. Not too bad for being close to the shortest day of the year.For their size, they're lightweight and portable. It makes packing up and moving the RV around pretty nice compared to the fully framed aluminum & glass panel I used to use.Update April 2021:Continued results were acceptable -- pretty much in-line with (lowish) expectations of flexible foldable panels. On sunny & pleasant early April days in northern CA, I was getting peaks of around 250 watts (out of two sets of panels). And got about 1.9kwh to 2.0kwh per day -- including tilting and adjusting the panels to follow the sun every hourish or so.For northern CA in April, I'd expect about 4.5 "hours" of solar per day: 400w * 4.5 hours --> 1.8kwh. So 400w of panels should give 1.8kwh, assuming the panels were sitting stationary. But with tracking (albeit manual) I'd expect around 2.2kwh to 2.5kwh per day.

Super product! Went camping, lights left on in the vehicle and the solar charger worked perfectly.

I use these to charge my portable battery bank/solar generator while camping.. bought two of them and it charges my 1.2kwh bank from ~20% to 100 in under 4 hours. This is great as I can charge the battery to full by afternoon and then recharge if needed before nightfall.. as another reviewer stated mine are producing about 145-160watts on a hot day (for one panel) when I have the two connected they hover around 260-280.. On a colder morning earlier this summer I got both of them up to 345watts which charged my bank in 2 hours.. they do “sag” if in hot sun so I just put a basic 2x4 underneath for support for optimal sun angle. They fold up nicely and the pocket that is sewn on is rather helpful for extra cables and whatnots.

Don't buy! The most i got out of this pannel is 80W .... In full noon sun!
