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!

Purchase 400W (2 sets) of these for my off grid power requirements, very happy with the quality, performance and price. Bifacial is a plus that didn't seem to add any cost over the one sided panels.

Work great I notice a 10% increase over my older Eco -Worthy minifacial I cant wait for the snow to clear .

Puts out at least the rating that it says it does.I can tell you for a fact.It survives three quarter inch hail it hailed for an hour and a half.And this panel wasn't shattered or broken at all the only thing I can add is when you get the panels in.Don't wait too long before you open them.Make sure that none of them are broken.I've had that happen to me once out of like fifteen panels or something.So it's not too bad, but be sure to check

Worked right out of the box for me. Plugged in straight to the Bluetti and Anker with the Solar Cable and was able to get a charge. I'm just laying the panel flat for camping situations and not ideally pointing it at the sun the whole time, but on a bright day I have seen it go up to 70~80 in. More than enough to top off the Anker, or give at least a little back to the Bluetti. I'm not off gridding at all and just messing with solar, so more than happy with the results from this panel for now, mostly for the price. Seems durable enough, mostly for the price. Dont' think it's going to take a direct hit from a falling tree branch or anything, but for handling and travel, it's been fine. Did recently get a solar charger controller to test with direct Lipo battery input, so I'll see how it goes, but don't expect any issues with it after how it's been for the battery packs.

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

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.

Trustworthy product.

Very good item works well

This solar panel performs very well and delivers consistent power output. It’s sturdy, easy to mount, and has held up great through different weather conditions. The build quality feels solid, and the connections are secure. It provides good efficiency for charging batteries or running small systems, and the 100-watt capacity is perfect for portable or off-grid setups. A dependable and well-made panel for the price.

100W as advertised. Its May 4th on the 49th parallel and I had the panel at 60°. Simply plugged in to my Bluetti EB3A. Very happy with this purchase.

This is an amazing product fully gave its 100watts. Bought 4 of these and made a solar kart. Would 100% recommend. Better quality and cheaper price than competition.

I have owned one panel for a year now and use it to power my Bluetti EB3A portable power station. It powers my laptop and Starlink as I work each day in remote locations out of my truck. This panel usually puts out in the mid 30s to high 40 watts. Not quite enough to make it through the day. If I am diligent about aiming it directly at the sun, I can get up to the mid 60s. The highest output I have seen is 65 W in perfect conditions. One other note is that if even a small amount of shade hits the panel, there is a dramatic dropoff in output that seems to be disproportionate to the shade. My hand shadow will reduce output to about 50% or even less even though it only covers less than 10% of the panel's area. A passing cloud will drop the output to 0. Those are my only negative observations. The aluminum frame is sturdy, and I move it around a lot from the roof rack, to the ground, in the truck, or leaning up against my shovel as a stand.
