Thanks to community member DealzRGood4U for finding this deal.

Features:
  • Newly upgraded 195W N-type bifacial solar panel - with excellent high-temperature resistance (less efficiency loss in heat) - features 25% conversion efficiency & 18 busbars (enhanced current transfer). Size: 58.86"L x 26.18"W x 1.38"H
  • This panel captures sunlight from both sides, boosting energy yield by 15% - equaling over 100WH more daily per panel under 4 hours of full sunlight. For max efficiency, pair with tracker/45in mounts and install over highly reflective surfaces like snow, sand, or glass
  • Features super-strong tempered glass, corrosion-resistant aluminum & IP68 waterproof rating. 2 diodes boost high-temperature resistance, ensuring 30 years of stable use - lasting 10 years longer than standard P-type ones
  • Comes with pre-drilled holes, grounding holes, and drainage holes - even beginners can install it easily without professional tools. It fits seamlessly for boats, RVs, rooftops, farms, and home, meeting your diverse power needs

Below $70 per panel is the cheapest I've seen for these. Usually it's around $75.
If you test each panel individually, you will get 90%+ and even over 195w but once you put them in an array, it will end up around 80%-85%.

That's now how it works. It's not that simple. This isn't the only factor (there are many) but a lot of how much power you can get from a solar panel correlates on where you live relative to the equator. Not only is the equator the closest part of the planet to the sun, but at the equator, sunlight has to pass through the least amount of atmosphere before it gets to the panel relative to further away from the equator. Sunlight also hits at a direct 90 degree angle so there's more intensity per square inch (surface area). The further north or south you are from the equator, not only is the angle less direct so less intensity per sq inch, but also the more atmosphere the light has to pass through because of the angle and the curvature of the planet.. When people say they get so and so many watts from a solar panel, without saying where they live, it means little to somebody that doesn't live in the same area. There's so many variables that effect how much power a solar panel gets. Even with the same exact panels, somebody that lives close to or at the equator will get substantially more power from his panels than somebody that lives closer to one of earths poles. Keeping it within the States, Alaska is still 8000 miles further from the sun than Florida.

PER AI: The Sun is at 30° in Alaska but 50° in Florida, sunlight travels through about 2.0 vs. 1.3 air masses—roughly 53% more atmosphere to reach Alaska vs Florida.

So not only is there 53% more atmosphere the sun must get through, Alaska is also 8000 miles further from the Sun vs Florida. All this adds up and makes a big difference in how much photovoltaic energy a panel can collect.

Very good reviews for this newer version of the panel. For $135 Its worth it for buying from a well known company. However there is a new seller with cheaper 200w bifacials been posted here a few times as low as 91$ for 400w total. I bought some of those and happy with them

Good Lord that's a lot of wordings there.
Doesn't take a genius to know the results are different around the world.
I have 18 of these. I'm letting people know real life results.

The whole point is your real life results most likely aren't going to be the same as others real life results.. So you telling people what they are going to get based off what you got isn't going to be accurate unless they live somewhere that gets the same solar irradiance as the area where you live. I get the feeling you don't understand what I'm trying to explain. In the simplest terms, you telling everyone they will get 90%+ and even over 195w out of these panels just because you did is not how it works.

Two questions. Did you tilt them to 30 degrees? Did you mount them with the backside of the panels white? AKA white vinyl? Thanks

arguably the most important piece of data is the voltage open circuit can't find it anywhere on the AliExpress ad

I have 3, but with a 10AWG cable, I get an 80w drop from 100ft.
For reference, right at the panels, I get about 235W each, in full sun.
I either need 8AWG, because sometimes these cables are iffy, or try to find a closer spot.
