ECO-WORTHY2pcs 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.

Solid, well built solar panels are great for Solar energy expansion or new installs on an RV. The data label on each panel speaks of their excellent functionality. I tested them before installing on my RV and they are everything I had hoped for. Highly recommended to all!

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.

Tested in full sun mid afternoon at 42 degrees N Lat. in December and recorded 98 watts in my Bluetti power station. This is the 100watt, non-bi facial panel oriented at the sun. The panel shown in some of the ads on Amazon for this panel show 16 bus bar (16BB) panels and this is not, its a nine bus bar panel. The frame was slightly dented in shipping and the glass surface shows signs of scum residue but neither of these affected the performance.

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.

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.

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

I love it
