Features
- [ Bifacial Solar Panel ] Bifacial solar panels using 16BB solar cells, backsheet using composite materials, transmittance up to 91.5%, conversion rate of 25%. In addition, in order to utilize the higher efficiency of the solar dual panel, it is recommended to match the solar tracker bracket and four-panel bracket. The solar tracker bracket and ample light space under the bracket can make the panels work better
- [ Easy to Install ] Size: 35.63 x 23.03 x 1.18 inches, single panles weighs 11.68 lbs. Diode comes pre-assembled in a junction box with a pair of pre-assembled 2.95 ft. cables. Pre-drilled holes on the back of the panel allow for fast mounting it on the roof or bracket
- [ More Efficient Power Generation on Rainy Days ] Almost 91.5% light transmission allows the backsheet to convert scattered light from the sun so that it can continue to provide unstoppable power to your off-grid system on cloudy and rainy days when sunlight conditions are not so favorable
- [ Wide Range of Applications ] Bifacial solar panels are used in a wide range of applications for sunrooms, RVs, yachts, farms, or off-grid systems for homes
- [ Durable and Long Lasting ] Our bifacial solar panels are built to last with IP68 rated junction boxes that are waterproof and able to withstand wind loads of up to 2400Pa and snow loads of up to 5400Pa. In addition, we have upgraded the package of the panels to reduce the damage caused by transportation
Description
Back in 2007,three engineers realized that independent clean energy could change our life.So they decided to devote themselves into it.From then,they initiated the exploration in Solar Energy and established the brand ECO-WORTHY. After 16 years of consecutive R&D,they have built their own factory and production chain now,and take the lead in selling lithium batteries.ECO-WORTHY has become a mature brand with a place in internationaI markets.

Size: 100W Bifacial 2-Pack Solar Panel
Routinely producing over 100 watts per 100 watt panel here in wyoming. We spend the majority of the summer in the mountains avoiding the heat and with 4 of these panels, we never run out of power. Couple the 400 watts of panels with a 300ah lithium battery. It seems so many things these days dont work as advertised, I found these to be the exception. Very happy with them. Fyi, all panels run in series for highest voltage.

This is a preliminary review, as the product is not fully installed into the system yet. However, the initial open circuit voltage test performed as it should have in full sun, and matched the value as listed in the specification. The panels arrived undamaged and were well packed and protected in the shipping carton. UPDATE March 2024. I was so impressed with the initial performance of the two 100 watt bifacial panels purchased previously, I ordered two additional panels, and those also arrived well packaged and were not damaged in transit. According to the specs, four of these panels would produce a total of 400 watts under ideal conditions. With these installed at the proper angle, and tested in full midday sun, I measured 421 watts in the system, so they meet and even exceed their specs. However, it must be noted that this system is installed at a high elevation (over 5000 feet), so the sun's intensity here is greater than in lower elevations. And of course, under cloudy conditions the output is reduced, but that will happen with any panel, no matter who manufactures them. Be mindful of the conditions you test these panels under before you pass judgement. Would highly recommend!

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.

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.

Size: 100W Bifacial 2-Pack Solar Panel
Update: I have gotten a multimeter to test the panels. 4 panels in series was yielding 90v and 3.6a for ~324 watts. So the panels are likely fine. I'm not even using the bifacial aspect at this time as I still need to construct a stand. I have determined that the culprit for my issues is likely the mppt in the power station I'm using being low quality as the multimeter is showing consistent values yet the power station is reporting numbers all over the place constantly changing between 150 and 250 watts. and I'm only getting 100-130 watts on 2 panels. I tried changing angles and nothing. Quite disappointing. I wish I hadn't gotten 4 packages to total 8 panels, but luckily this is only for emergency use. Maybe in a couple of years there will be other budget panels that can perform or someplace to buy the name brand 400 watt panels without needing to buy a pallet of 10.

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.

I've ordered these on numerous occasions and I attest to the quality of the build and packaging. I'm curious how much silver is in each panel (100 W each), but to prove I appreciate this product I ordered some more today - that is like the 4th or 5th order made - and I want to keep the panels in my setup all the same if possible - and once you find one reliable - well hopefully you all keep making this panel. I suspect I may order more. My guess is the panels have less silver than the panels of old cause the price of silver has really increased, but I suspect they have silver in them - cause goodness gracious me - silver is the best conductor of electricity. Now given the price of silver is increasing my suspicion is the price of these panels will likewise be increasing - and that is the cost of supply and demand - but please keep this product line going.
