200 Watt Bifacial Solar Panel 2pcs 100 Watt Monocrystalline Solar Panel Module Off Grid PV Power for Home, Camping, Boat, Shed Farm, RV,12V/24V Battery

Good panels, great price. Solid quality. I hooked 4 up in series and they work perfectly. These all come from China and are a commodity now. These seem very well made and we can dither about nerd stuff all day, personally I have other stuff to do. I just wanted decent panels for cheap. Pay more if you want to but at this price it isn't justified, much like light bulbs or tomato soup or LiFePO4 batteries.

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.

All I have done since the solar panels have been delivered is go over each panel and check on the quality and make sure there's no damage etc. Thankfully I had zero issues with delivery. Each box contains two panels so i have 4 panels total. The only thing that I would of liked added to theses panels would be corner protection. Other then that I'd buy these panels all day. Great price and nice quality. A welcoming addition to my solar setup. As I get more into testing out the panels I'll do an update if something doesn't work out. As of now I recommend the panels for there build Quality and price. Check out the Reviews!! Thanks.

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.

got 4 total of these 100 watt panels and they are working pretty good I think. I put them in full sun at different angles and checked the watts, all put out over 100 watts at the best angle. they are well made and am happy with them so far but only had them for a couple of years now. they came two per box and one box was completely full of glass pieces. it was the shippers fault but eco worthy could have put just a bit more protection of the front panel. probably wouldn't cost a lot to add just a little something like another sheet of paper. i guess it adds up in extra cost if you made a million of em. amazon did me right and refunded the broken panels and ups picked it up at no cost so it worked out in the end.

I definitely love these panels as they work and deliver what there supposed too. This is my second pair and I grabbed them both on sale from amazon for $100. The only complaint I would have is there not exactly the same size even though they were advertised as such. It would definitely be a problem for someone mounting them in an existing array but as you can see for my popup camper boondocking setup I have them freestanding so I can adjust them throughout the day to the sun. I’ve got them run series parallel and have seen 365watts with my epever 40amp controller, charging my 2-200amph lifepo 4 batteries. All in all i’m happy with them and the results they provide. Shipping was fast and they were packed well and protected. Just so you know the size difference, my first two panels I purchased were 39.75” x 18” and the second pair are 35.25” x 23”. So definitely not the same size. As I said, if you were fitting them into your existing array you might be a little disappointed. Otherwise there great panels that put out the advertised wattage.
