Description
- 【Bifacial Solar Panel】Bifacial solar panels using 12BB solar cells, backsheet using composite materials, transmittance up to 91.5%, conversion rate of 23%. 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: 39.76 x 18.11 x 1.38 inches, weighs 13.62 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.

I have bought and installed 16 of these 100W 12V Eco-Worthy panels from Amazon, to add to my original field of 4 100W 12Vpanels made by Ramsond (they were the cheaper panel a few years ago, Renogy & Eco-Worthy seems to have taken their market place recently) Each of these panels produced 5.5A+ and normally over 20V in full Florida sun, as measured on my multi-meter (I’ve uploaded photos with this review)
I have my 20 panels wired in series, in groups of 4, running to my Outback Flexmax80 MPPT charger via two 10AWG runs, to my bank of Trojan Deep Cycle Batteries. These panels give me the expected VOC of 80+ (48V nominal) and at the sun’s peak of the day I get the expected 27 amps of current. (MPPT charge controllers take the extra high voltage and converts it to charging current, if you’re not familiar with the technology, check it out – super efficient)
The only issue (really a non-issue for them) that I didn’t catch is that the panel is slightly thinner than the Renogy or Ramsond, which made securing them to my rack just a little bit uneven next to the fatter older panels. Also, the corners on the panels look a little sloppily put together, a few are bowed/bulged out instead of having a neat seam, but this aesthetic doesn’t appear to create a functional problem and certainly cannot be seen from the ground when roof mounted & producing energy – so it’s not a big deal for me.
The panels are, in my experience so far, worth the money ($140.00 currently) compared to other competitors in the market place. I’ve liked them enough from my first order to place a couple subsequent orders to get me where I am now at 2000watts (2.0 KW)
As a quick ending note for any newbies – you have to realize that in the realm of solar a 100W label on a product rarely gets you a true 100W of power. Using an MPPT charge controller will help with squeezing out the potential wattage, but especially if using a standard charge controller you have to understand that wattage is figured based on Amps out x Voltage, and non mppt charge controllers use the batteries voltage to determine the charging voltage. For example a fully charged 12V battery will be average 12.8vdc so a charge controller will charge just slightly above that – say at 13.1V. So, figure 13.1V charging potential X 5.5amps (lets use 1 panel in full sun for simplicity) = 72watts of power from that panel. If using a MPPT charge controller, it takes the panels VOC, which in this case is about 20v x the same 5.5 amps = 110watts of power and is able to take all of the power from the panel it COULD produce and push more current into the battery than it otherwise would. So, conversely a discharged battery at say 11.8V (charging from a panel like this, in full sun) x 5.5amps = 64.9watts into the battery. Panels like these CAN produce their rated power in full sun and generally with the assistance of a mppt controller (because until your battery is darn near charged, you only get about 2/3 of your rated power production… and by then you don’t need it as much because your battery is full!) I hope this helps anyone who may be mystified as to why their power production calculations aren’t working out – usually it isn’t the panel – it’s the charging conditions including angle to the sun / time of year. Since going to MPPT, I’ve increased my solar harvest a lot… All after several years of head scratching. Happy harvesting folks! – David

I ordered the 100W mono panel a year ago to enable off-grid camping. The panel size matched the product description (21″ wide) and it generated about 75W in direct sun, which charged a battery station for running my minifridge, fan, and lights.
I just now order a second panel for faster charging. Amazon said it was the same panel as before. The new panel is actually only 18″ wide (pictured) instead of the advertised 21″. I was about to send it back, but went ahead and tested it in the sun in a side-by-side comparison with the older panel.
The new panel generates 85W here in Ohio in the winter, when pointed directly at the sun, which is better than the older panel’s 75W. Pretty good for a panel costing less than $60. So I’m keeping it.
Just a heads up that if you need your panels to be the same size for your setup, you might want to know that the panel I received was only 18″ wide. Length was as advertised.

Worked as advertised amazing price incredible technology

Used these (4x 100w panels) for two full summers now on the RV. Make good amps to feed a 200ah LiFePO4 even on the ambient light days. No issues. Pleased, and highly recommend these to everyone.

Panel was packaged grest and looks sturday and well built. Produces up to 21v dc but never generates more than .05 amps regardless of voltage. Using to keep a lithium battery charged powering two 5v security cameras despite full sun in AZ panel can’t keep up with this tiny draw of .04amps and battery drops below 12v after a couple of days. Disappointed that this big panel can’t produce more than 0.05 amps in full sun.

I’m new to the off grid solar camping world. Started with these price point and from reading other reviews. I’m managing to pull 130w at 9-10amp in direct sun. There working perfectly for me maxing out my 10amp controller with 2 – 12v 110amph batteries in parallel. Seem solid enough for the money. Wanted to be able to follow the sun during the day, so mounted on two separate 30* angled frames.

Ended up getting ten from last installation for an old city home.
Real panels, real testing STC, serial number requirements. All specs listed are completely true. I have tested them using the proper electrical tools.
Works great in series , parallel, or hybrid hookup. Only thing that confused me, Was how Eco can afford to make solar available to everyones price range high quality and feel durable…
Frames on a few can be a bit sharp on corners but that’s to be expected.
I will easily be purchasing more and recommend to anyone who asks.

I recently bought a solar generator system, it was a small system so i could understand how it works, but i was in the desire to begin increasing my solar panels. So ecoworthy has become my go to for solar panel equipment. I have not had any issue with this company or this product. Im taking my baby steps to try and do my part to alleviate my electric bill and these are perfect to begin my plans.

They work fine

This is an update – First panel had an issue, but the company ( DC House ) was quick to respond, very professional and fully helped me out with a new panel. Issues do happen, but it takes a great company to make it right when something is wrong. My system is up and running again and I am happy. I will buy from DC House again as they proved they are reliable. This 100 watt panel is producing good power.

I’ve bought several of these and they work perfectly, I’ve installed them on my van and food trailer. I do wish they would include some Z brackets but they’re not hard to get. Highly recommend these are a fraction of the cost of other brands yet perform just as well.win win

ordered 8 panels, upon receiving them, two of the boxes where dinged up and torn. i figured i would be sending two panels back but after inspecting them, they both where not damaged. i did have to wait for three days before being able to test them. i had to clean off all the residue and glue that had made its way onto the glass, pretty simple task using a razor blade and Windex. i tested all eight panels within 20 minutes of each other. it was a bright clear cool day. all the panels tested 25.2 – 25.4 Volt open circuit and 4.40 – 4.45 amps short circuit. i am happy with the initial testing. once i get them mounted and in production i will report back if i find any issues with continued output. i plan on ordering more very soon.

Bought this to add to my previous ecoworthy 100w panel. It is a different dimension but it doesn’t include the mounting “Z” brackets. Just be aware they need to be ordered separately. A bit disappointed
