I have 2 of these and 4 of the monofacial. They all put out right around what they're supposed to. Bifacial, of course, does a bit better. This is a great price, even better than the deal I posted a few weeks ago.

I'm getting 2 more to complete 2 parallel strings of 48V.

Better deal if you buy 2 and use code CDUS08 for $8 off.

And yes, I trust AliExpress, like I said I have 6 panels from them already and they all work perfectly fine. Only mentioning for those that are on the fence about buying from AE, cuz I know there are a lot of AE haters out there. And no, I'm not a shill.

Serial is not ideal if you have shading. Parallel works better. If you have 4 panels in a series and 1 panel is partially shaded, the entire string is held back by that 1 panel. Since at the combined voltage, it'll only output the number of amps that shaded panel can put out. Which isn't much. You can increase output by fully covering that shaded panel so that it drops out and the charge controller adjusts to the lower voltage. With parallel that doesn't happen. The other 3 panels will still be going full bore. So I parallel when I can. Serial only if I have to.

The 100w panels keep getting cheaper and cheaper. I'd like to see larger panels come down like this.

It ships from a US warehouse so should be included in the price.

I couldn't get the $8 off coupon to work when adding two to the cart, anyone else had success?
BTW I test the panel bought during the previous $33 deal, and in optimal condition it outputs 85-85w to my EcoFlow Delta Max.

858Wh per day under ideal conditions for a 100w panel my ass. Bifacial or not. It would need to collect 172 watts per hour for 5 solid hours of sun per day to accomplish this. In the real world, anyone should be ecstatic if they collected 858Wh with a 200 watt panel.

$30 is not an exceptionally low price. I already posted a link to another panel at the same price point as these. Even Renogy which has been used as an example of an expensive panel is currently selling a 100 watt panel for $36.

That's a lot of panels for something that you haven't gotten before. My hat's off to you. Since I tend to buy a couple to check out before buying more. But with all those panels you can be like this guy. From his 15 panels he's getting 1060 watts.

Who said I had not bought these panels before you are making an assumption and as for being a know it all I do have these panels already and it depends on your mppt efficiency and shading stop being a know it all for every video you show me that says they are getting 75% I can find videos saying they are getting 100% so stop The pissing contest...(I get about 90 percent efficiency on my existing panels in good sun or more..)
Man you are the biggest shilll around .... And if you can't spend 30 bucks and buy one and dismiss it out of hand then you are not serious but just a man drumming up business for your favorite insider..
I have dealt with your kind that push the more expensive version with their own agenda's,,,, people I suggest you buy one and try it and ignore the internet experts and find out for yourself s for all we know this guy could be an eco worthy sore loser..
So I am done replying to your know it all answers that refer to cherry picked videos.... every one spend 30 bucks try it and then make your own determination if you can't spend the 30 then get out of the business of trying to do solar..

I bought a few of these when they were called 18v bifacial and this is under the general idea that ecoworthy has not changed the formula... At that time they were much more expensive..

I hope that's not in reply to my comment as that(825w) was intended to reflect 11 panels in series total in an hour at another individuals rating of 75% per panel was mentioned... not a single panel..

No no. not you. I was actually responding to what it claims in the product details. You're good. It says.. copy and pasted.

You did. Otherwise why did you say "I shall see"? If you already have them, you wouldn't have said that. It makes no sense.

You're good. He seems overly sensitive about it. The two things are so similar that even he mistakes the two. It's like they were both written by the same person.

Oh I am sorry no one should ever just buy one panel and verify for themselves we should trust you as the god of all that is solar,,,
Yep people spend what you want and ignore the internet experts just try them yourselves 30 bucks its your choice don't let anyone convince you otherwise..
I am not mad I am just convince since you are so persistent in not letting people make up their own minds that your willing to brow beat us to death with your "I am the ultimate arbitrator of the solar truth shtick"!
Give it up and let people decide don't browbeat us to death with the you know best routine especial for something as cheap as this..
Man you know how to push and push you'd think it was a pissing contest for a gold mine and not a cheap panel..
Echo worth does and has change tech so I left that open but you go ahead and twist it to your ends...
Now can we stop this and let people just buy what they want rather than you trying to get ego points I suppose you also know what the meaning of life is "Mr Google" because you know everything?..

Nice, bought two more.

The last panel I bought, of this exact same unit (I have one bifacial and one monofacial), hit 92W peak some days ago. I've found both types of Ecoworthy panels to perform the same when laying on the concrete. Even if it doesn't go any higher in peak mid-day summer output, in a couple of months, I'm happy with that number.
