ECO-WORTHY 2pcs 100 Watt Solar Panels Monocrystalline Solar Panel for 12V/24V Battery RV Marine Boat and Other Off-Grid Applications, 2-Pack 100W

As the price has been plummeting on these i’ve been buying them pretty much continuously as I can afford them. I find that in real world application in Southern Indiana on a clear winter day at a perpendicular orientation to the sun. I’m getting about 95 W. This is about what I expect out of solar panels. They are so cheap now that I don’t even bother and making sure that they have optimal tracking access to the sun. I have some of them oriented to morning sun some of them oriented to evening, sun, and some of them are used as border walls for the patio. That way I can make use of all of my available space.I’ve strategically wired them so that the controllers get input from panels as the sun moves so as to maximize my controller inputs from the panels, i.e. one one panel set is starting to lose sun, the next panel set is starting to gain sun. That way, the controllers are having the most made out of their time.Because they are getting so cheap, whenever I find a coupon or promo offer, I just buy it. I have a bunch stacked away so that if I have any damaged, I can just drop them in and replace them. So far in almost 40 years of being off grid, I’ve only ever had two panels fail. And in about four years of using these, none have failed and none have been damaged. I’ve only ever had one arrived damaged, and it was quickly replaced with no questions asked.

Why did you pick this product vs others?:Price and bifacial.

These are good panels, I first used them to charge my Eco - Flow, now I use them to charge my small solar setup. It takes about 1 day to fully charge a 100 aMh deep cycle solar battery. I have them wired in parallel. So far I can get a couple of days of just lighting, with running a Fan & lighting I get one day. Happy with the panels.

The packaging was not very protective as seen in the photos. The delivery handlers ripped and dented the boxes. When I checked the product in each box, there were some dents to each of the panels. Thus, eco-worthy needs to better protect these expensive and fragile items.Next, despite the dents, I tested the 2 panels front and back and they work. These are genuine bifacial panels. The front was putting out about 62 watts while the back around 47 watts. They both worked well in series putting out around 142. More testing to be done later.I have yet to test them in semi-cloudy skies.I have ecoflow panels as well and they include mounting brackets and bolting assembly. It would be nice if eco-worthy included mounting supplies too.Overall, the panels look nice and are not very heavy. Despite the dents, I plan to keep them and hopefully, purchase their sun tracker in the future.

I have several of these panels and they are equally comparable to r3n0gy panels that cost 2x. Same output, same connectors. Smaller size panels. I also like that they have a solid aluminum frame. No blue cap ends.

This is my first experience with solar; these are up and running perfectly, with simple connections and plug-and-play.

I wasn’t expecting to be this impressed, but this ECO-WORTHY bifacial solar panel is honestly great. It was lightweight and easy to install, the pre-drilled holes and cables made setup fast on my house rooftop.Performance-wise, it really shines. Even on cloudy days, it still generates power thanks to the bifacial design. That 23% efficiency is real, not just a spec. It feels solid, durable, and reliable for off-grid use.I’ll do a six months review after they’re using it for a while.It arrived securely packed, which I appreciated. Though I did notice it was shipped facing outward instead of inward—I’m not sure if that’s standard for solar panels, but it might be safer the other way. Either way, mine arrived in perfect shape, but anyway, the seller states they will replace the panel if damaged in transport.If you’re looking for a compact, efficient panel that works rain or shine, this is a great choice.

Panels work as they should. However both panels have dents in the frame and there is glue in several areas on the face of the panels. MC4 connectors are not labeled. I’ll use them as it’s such a hassle to ship them back.
