I'll be honest. I really didn't know what to expect with regard to performance of this type of setup. But, I have to say they work really well. Now I just bought these so longevity wise I don't have that information, but I tested these as soon as the sun came out about 9:30 am. They were generating 21.8 volts at 13.8 amps equaling 288 watts! Nice! That's a 90% efficiency right out of the box of their stated capacity. Incredible. They're super compact for what you get. Lightweight, easy to store, a nice durable material on the outside for protection, and are somewhat rigid. Cons: When I first started looking at these I saw a picture showing supports behind it holding it up. NOT! These do not have back supports any kind. You are on your own for that. The cord seems just Long enough to be helpful. The charge controller is a lesser expensive 20a PWM but it is constructed very well with plug and play connectors for a very easy setup. Of course I'll have to test the performance of the charge controller, with regard to actually charging a battery, so we'll see. I'll compare it with my MPPT controller and see if there is a major difference. But as it is, it's a really good setup. I'm very happy with it and highly recommend.

I use this to charge up my jackery power station. Plugs right in. Straight out of the box I’m getting about 116w draw in the high noon sun. Seems to me none of them draw to their “full potential”. Thats perfect conditions etc. To me this is exactly what I expected and wanted. Charges me fully in about 2 hours or so. I wouldn’t leave it outside all the time but it seems to be a good value for the money. Very easy to use.

Getting a lower wattage one wouldn’t charge fast enough for me. Spending double for a higher wattage or “hard shell” panel didn’t seem worth it. This is perfect to juice you up without breaking the bank.

4.0 out of 5 stars Nice additional Solar Panel for RV
Reviewed in the United States on June 10, 2024
The panel is light and does fold well. It does not have a stand so you have to order one or make one. It will not stand up on its own. Interface and controller work well, I just had to order an additional connector to connect to the SAE (Zamp) connector on my RV.

Since they arrived, I've been quite cautious with my panels, given the mixed reviews, reports of very little power delivery (both initially and degrading over time). I suspected that the people reporting decreased power production over time may be over-bending and over-flexing their panels, damaging them over time.

I've been using my panels for a few weeks now, and so far, my experience has been very pleasant! I also have made sure not to bend or flex them, avoiding leaning them against anything (esp at a harsh angle). So, I've really just placed them on top of my van.

I've been very happy with the power delivery. I have been sampling it over different days in different conditions:
- Midday, light clouds: 128W-149W @ 16-17V, giving 8-9A. (see images of screenshot for example @ 146.2W, and the partly cloudy sky)
- Early morning, full sun: 90W @ 18V, giving 5A
- Midmorning, very cloudy: 40-65W @ 16-17V, giving 2.5-3.5A
- Summer evening, cloudy, tree coverage: 20-40W @ 16-17V, giving 1-2.5A

So, I was shocked. I've seen it get up to 160ish Watts, and never expected to see more than 75% power (150W). So I was happy with that. And I'm also surprised that even with pretty heavy clouds, I was pulling in roughly 3A. Since I'm mainly planning to run my laptop and phones, (and possibly a small fridge), even this 3A is enough power for me if I let the panels run all day.

One other location I was curious about was placing panels on my dashboard. I want to try exposing just a single panel, hoping that it can fit on my dash without shadow. 2 unknowns: I don't know how much my windshield will block the light, and I don't know if 1 panel can pull 1/4 of the full power potential. My understanding is the panels are wired in parallel, which is excellent, because they're essentially operating independently, or additively. (If they were wired in series, that would mean whichever panel had the lowest power, that would be the max power possible from every panel.) Still, in practice, I think I'm getting less than 1/4 power from the single panel. My thought is that the full panel covers so much ground, it's more likely that at least 1 panel will receive good light. However, the smaller footprint of the small panel will only pull 1/4 power when it's getting full sun. In other words, in full sun, I suspect the single panel will pull 1/4 of the 4 panels. But with any clouds, having all 4 panels present will actually help maximize power.

I have a LiFePo4 battery, so the included charger won't work. Still, I'm happy to have this junky little charger in case I want to drag the panels out to the beach, providing USB power, or for emergencies to trickle power into my car battery.

It would be nice to be able to lean these panels against a wall, or the side of my car. I'm just too nervous that I'll damage them with flexing. I'm thinking about creating something out of some old tent poles, but haven't yet landed on a design that I'm excited enough to build out.

The other day, I came outside to find the panels had blown off my van and were just laying in the lawn. They seem to be still functioning fine. So, I'm happy that the panels are sturdy enough to withstand a 7 foot fall onto grass. I also need some basic solution to keep 'em strapped down, because I don't want a $200 kite.

In terms of the quality, I'm pretty happy with the fabric itself, the quality of the handles, etc. The little metal rings seem pretty flimsy, but I can work with that. And some of the stitching is coming undone, leaving some dangling threads around. Again, I can mend that and deal with it.

Overall, with a couple underwhelming features, I'm more than happy with the power output. Nothing in this price ranges is even close, and I can't even find another panel offer this kind of wattage.
