ECO-WORTHY 100 Watt Solar Panel 18 Volt Monocrystalline Solar Panel High Efficiency Module RV Marine Boat Caravan Off Grid

I have purchased many Renogy products and they never disappoint. Wanted to build a small system in my shed and Eco-Worthy panel was much cheaper, so I thought I would give them a try. System has been working great with the panel. Renogy has always been a good product and now I see the same from Eco- Worthy. I guess I will just have to check the sales. Both good products.

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

This is a great 100W panel if you are looking for 18V in your setup. Check the actual panel parameters on the label or on the product page to be sure it’s the right one. These panels are higher efficiency and space saving compared to polycrystalline panels. The panels produce what they claim. Packaging and delivery was decent. Out of 25 total panels, only a few had some minor dents and blemishes on the frame. The solar cells were all free of damage. The mc4 connectors were all in perfect condition and worked well. I highly recommend.

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.

Update! These all survived the storms unharmed and are now all connected to my little Ecoflow, which will soon be an Anker Solix C1000. After that they’ll be connected to a solar charge controller and charging a large LiFePo4 battery. I know these will do very well. They generate power far longer than I could have expected and I really don’t have any issues running my little fan in my car and soon I’ll add my Ryzen powered laptop to the mix for my day off! Right now my only limitation is my Ecoflow river 2, which limits solar input to 110w. I’ll be making full use of these with my new Anker C1000, though. Once I have my Anker C1000 I will be strongly considering adding my two year old mini fridge to the mix and see how things go. I may even do that this weekend, just to see how it goes. I imagine I might be able to power it nearly constantly with my River 2, if that’s all that’s running. I highly recommend these panels! Original: These are a fantastic deal. I have three installed on the roof of my car for a large battery bank I’m making and I connected one to my Ecoflow to keep it charged until the battery bank is completed. The one that’s connected to the Ecoflow peaked at 101 watts sitting flat on the roof of the car! I’m absolutely thrilled by these panels. I did purchase four, but only had room to install three, so I have an extra that I’ll purchase another panel to make a portable solar setup with. I installed them this morning and later tonight severe storms with large hail and strong potential for tornados, so let’s see if these hold up to this impromptu torture testing! I really had no idea the storm was coming. The warning came out a few hours ago. If I never leave another review, expect that the worst has happened.

WORKS Great

This is a great panel, it arrived fast and in perfect condition due to good packaging. It does put out the true 100+ watts, in full sun I was reading around 5.1 Amps at 20 Volts according to my DMM, in full Southern California sun. I am running it along with 3 other panels of lower wattage and my charge controller reduces the voltage going into my batteries to around 14.2 volts but even then we had a day when the power company was doing some work, so no grid power that day but I was able to run my 32" (LCD) TV and a fan all day. It was running just off the panels, (the total wattage of all my panels is 160 watts) I know this because my controller has an indicator that lights if there is any draw on the batteries. I shopped around quite a bit before deciding on this particular panel and this is the best price I could find for a 100 watt panel. There are cheaper ones out there but they are usually poly-crystalline ( They have that kind of sparkly look to them, if you've seen them) but I prefer Mono-crystalline panels simply because I feel there is less opportunity for substrate failure with the mono-crystalline panel surface. These arrived with MC4 type connectors already installed as well as TWO reverse blocking Diodes installed in the junction box on the rear of the panel, the wires that come with it are about 3 feet long, you can buy extra MC4 connectors here on Amazon to hook up additional length as your needs require. Overall I consider this a very good purchase and I will be buying more as soon as I can afford to increase power panel capacity. Let me know if my review was "Helpful" to you or if you have any questions and I'll try to answer them. Thanks!

This is my first time using a solar panel and honestly its pretty good. I did see some poor quality with the metal but i honestly just need it to put on my shed. It charged my anker solix c300 up from 70 to 100 in under an hour. It only reached 66w under the sun with a small amount of clouds around. For the price its decent and better than those expensive portable solar panels.

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.

It works great

J'ai un panneau solaire portable pliable de 300w et il produit moins que celui-ci de 100w. Pour moi y'a pas photo, c'est un no-match. C'est un rapport qualité prix imbattable.

I purchased two of these a year ago, and they have been working fine. I typically get 3.5 to 4.5 amps at ~12v off of each panel on a clear day, depending on the azimuth and elevation in relation to the sun. ► The MC4 connectors are typical and fit nicely into the old connectors. ► They are well constructed. The dual-channel (running around the outside) outer frame is well sealed to the panel itself, and because of its aluminum dual-wall construction, it can easily be drilled for custom mounting needs when the four bolt holes aren't usable. I got these to work as replacements for the very old panels I had on our RV roof. I specifically wanted panels that had a little flex to them since an RV roof can flex and twist any panel that's too rigid or has been mounted solid can and will crack. I've had this happen a few times. I now use rubber inserts in the brackets, which mount to the roof so there is a little flex at that point. Plus, if the panel can twist a little, it has a far greater chance of surviving. Since we keep our RV parked outside even during the winter, they have been exposed to some nasty cold, colder than -40. Since we mounted them using flexible options, they haven't developed any cracks because of the shrinkage caused by extreme cold. They also don't seem to have suffered any when in direct sunlight in the summer months as they get extremely hot. If I need more for a similar application, I will buy again. If I was setting up a solar power system, I would go for a completely different panel. Too long to get into here.

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.
