My solar arrays are all 200w as I don't want to deal with bigger and heavier 400w panels.
I have 16 200w Eco Worthy right now(their latest ones) and they are great.
These will go over 200w in the optimal condition. I get around 2600w of the rated 3120w during the summer right now.
I've been trying to add to my older 200w array so I gave these a try.( I bought 4)
The reason why is that these are smaller. 26 inch width which will fit the Eco Worthy solar racks.
So far they are great. 3 of the tested on the solar meter at around 190w-210w(these are optimal condition).
The one stinker only got my around 160w. I'm going to try and get a replacement for this one.
For the price and the size, the results are outstanding so I just bought 4 more.
If you know 200w like I do, good 200w panels are around 30 inches in width.
The cheaper ones that are narrower(26 inch) are either much longer(like the Eco) or they don't produce much.
I said if they get over 170w on my meter, I would be happy and I got more than that.
BTW the LINK for this is not that cheap.
For me it's like $70/$140 but AE is weird like that.
There's several link to the same items from the same store at different prices.
If you know how to work AE, you can find the link with the lowest price.
UPDATED with a picture with both of these panels and the newer Eco W split face 195w panels side by side.
These 2 I found that are best inexpensive 200w you can find.
These are my Eco W 195 panels. 16 of them.
I get on average over 10 kwh per day and a full sunny day will get me 14kwh
I don't move them around so I don't actually get full sun on these array until 11am.
I'll post pictures of the Aeternasol when I get them up. I have 8 of them now.
Looks identical as my last 4 but the MC4 connectors are different.
Took them right out of the boxes and started measuring them.
Again, they are tested well ranging from 185w to 220w(yeah this one right out of the box was 222w but it dropped to ~212 and stayed around there). I was shocked actually.
Remembered I took them right out of the box and using a solar meter but it doesn't represent the real numbers.
Once the panels get hot, the efficiency will decrease and the actual MPPT reading will be a little less.
For the size and the price, the results are fantastic. I love the sizes as 4 of these will fit my rack.
No clue what the longevity will be like.
Let me point out that the specs for these panels are 25.18 Voc 23.04 Vmp and 8.68 Imp.
What I get from my meter from all the good ones are around 21 Vmp and 9.6 Imp so amperage are higher and voltage are lower.

Glad I'm not the only one (I guess?). I'm only pulling ~85w with my 200w Eco-Worthy panels. Less than ideal, obviously. CALLSUN seems like good bang for the buck. If anyone has any real world exp with them I'd love to hear it.
If you have earlier versions, they are crap as I have them.
If you have the latest version like the ones in the pictures I posted(the ones with the split line), no way they are only pulling 85w.
Callsun are expensive. I have 4 of the 100w versions.
They are very efficient but expensive. I got the 100w versions for ~$65 and for that price you can get this 200w.
The Callsun 200w panels go for >$150 and they are bigger. Same length but wider at 30 inches vs 26.
It's a no brainer which one to get.
The 2 problems I see with these panels are:
1) CS. Will they stand behind their products ? I never heard of them until now.
2) If you get one of the average panel like I got 2 of them. Average as in getting only 160w vs >190w.
Out of 10, I got 8 very good ones with 2-3 of them excellent. 2 are so-so.
I'm going to see if they will replace these 2 for me. We will find out about their CS.
I seem to struggle with panels staying in "good" condition in the Texas sun. They tend to get covered in dirt, poop, and often discolor or fade like crazy when left on barn roofs.
What's the best way to keep panels operational and in good condition without crawling up on the roof every week?

Wondering if you have any werchtay 200w bifacials? They produce more than ecoworthy 195w bofacials for me by 10-20%, under relatively ideal conditions. I have seen werchtay hit 220W with a good angle in spring, with a delta 2, I have not seen them below 87$ from memory.
If one has limited space like an rv roof efficiency/exact size details can change decisions.

So that's what, 3 of us in this thread with 200w eco-worthy's that aren't getting anywhere near that. It's a shame. I have half a dozen of their batteries and they're great.
Earlier Eco 195w all suck. It's their latest ones that are good.
The one that's 26x58 with the split line like the good ones in the picture I posted.
I have 16 of them and they are great. I get 2600w-2700w of the rated 3120w(16x195) on a regular basis.
That's 80-85% which is really good. Sometimes when it's cloudy and bright sun peak out, it will jump over 3000w briefly.
I have had various Eco W before and they all suck. I'm talking about the 100w and 195w bifacials and the 130w flexible.
They all suck.
The new 195w ones came out maybe 6 months ago and I hesitated in trying them.
I only bought them because I found someone online who tried them out and had success with them.
I tried 2 and they were great so I ended up with 16.
How I ended up with so many was that I tried 2 first ad they were good.
Then Ebay had their usual 20% off and I bought a 12 pack bundle for $999-20%= $800 making them $67 each.
Bought 2 more from Aliexpress to round up to my 16.
Also, I needed good 200w panels that are less than 27 inches in width so I can fit 4 on the Eco W solar rack.
Very hard to find these that are decent
Optimal as in I take them out when the panels are not hot yet and I have them directly facing the sun and measure them with my solar meter.
I still have a few pictures, wanna see them ?
Once the panels get hot, you lose a lot of efficiency.
I tried taking a picture but it settles down to around 215w.
The other 2 pictures are of the 2 panels that aren't too good, reading at 153w and 157w.
Gonna see if they will replace these for me or I'll just return them.
Out of the 10 I got, 2 weren't so good. the other 8 I put them up on the array and they measured from 185w-215w.
Again, I measured these with a solar meter when the panels were cool.
When they get hot and running through the mppt, you will lose some efficiency.
The newest ones with the split face like in the my pictures.
I have my 16 panels in a 8s2p. Rated at 3120w(16x195).
Just for a briefly second when a really bright sun peak out from the clouds, I got 3440w.
Sure it's just for a brief second, but these panels can easily go over 195w.
If you can get over 80% on a consistent basis, you're doing great.

I usually try to search for the same panels on Amazon and get some real world results through reviews.
I never really got good vibes from Werchtay which is why I never gave them a try.
I know there is a 200w HPBC that many companies put their name on it and that particular panel will go over the rated wattage.(but its big)
My focus has been trying to find 200w panels with width below 27 inch which allow me to fit 4 on my solar racks.
All the really good 200w are 30 inch in width and are expensive.
So far only the newest Eco Worthy 195w and this Aertensol 200w are 26 inch in width, cheap and very efficient.
There maybe more that I don't know about.
