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

Work great! Even run our air compressor!

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.

These Panals are perfect!!! Great Product for the price.

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've got 6 of these on my roof and I live in the desert, and these panels are still going strong. I think they can reach 90% efficiency if all conditions are right (sun angle, no clouds, moderate temperatures) and they also do a good job of grabbing small amounts of light. Connectors have also held up well.

This is my second purchase of the bifacial panels and my third overall. They arrived intact and do what they said they would do every time. I have a set up to charge my power stations and there is a high degree of reliability that I have come to depend on. My ultimate goal is to set up a charge controller with inverter but for now my power stations serve that purpose. I use the power station to power things in my Den like the TV, lights and related devices that are big draws of electricity, and it has helped lower my electric usage. I haven't used them to charge my LifePO4 batteries yet as that comes with setting up inverter/charge controller but will update if there are concerns. To say I am pleased is an understatement.

Excellent panels. I had been buying Eco-Worthy mono -facial panels, and was quite happy with them. Then one day, I went to buy another pair and saw that the bi-facials were at the same price on a sale, so I grabbed them. I hadn't heard any solid reviews of bi-facial panels, so I wasn't really expecting improvement over the monos, but there was a clear difference in their performance. Over the next couple of months, I purchased more of these and separated my panels into two arrays - 500 watts worth in mono-facial, then 500 watts worth in bi-facial. All cables are the same gauge and length. Each array runs through its own controller – both the same model, and finally into the same battery bank. The results will vary from day to day depending on several factors, but in a worst case, I got 10% more from the bi-facial, in the best case, I got 22% more from the bifacial, and an average over the month of August of 16% more from the bifacials. No matter how you slice it, I came out ahead - 16% more power in the same amount of space, and in my case, for the same price as monofacials.
