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

Good so far! Still testing my setup but these were on sale and had to jump. Going to build a rack next with adjustable angle. Mounted a little solar target device with velcro. Majorly helped drive up voltage. Have them wired in series. Generating a peak of 180-185 watts at to my Anker Solix c1000. Not a ton of depth in my set up, but think I can run my full-size refrigerator indefinitely 24 hours a day and power outage. Have plans of buying two more then running series- parallel.

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.

I've combined two of these 100 Watt solar panels to create a 24V system, and they have worked great for the most part. The panels were a bit dirty upon arrival, with some residue on them. After a good cleaning, I noticed a small power boost, which was a nice improvement. One thing I really like is the size of these panels. They fit perfectly into my setup and were exactly what I was hoping for. They provide a solid output, typically reaching about 70-80% of their rated capacity even with ample direct sunlight. While I haven't managed to get them to max output, the efficiency is still quite good for my needs. Though, the initial dirt and residue were a bit of a hassle, and the fact that they don't quite reach maximum output despite optimal conditions is a slight drawback. Nevertheless, their performance has been reliable, and they have met my expectations for the most part. Overall, the ECO-WORTHY 100W solar panels are a solid choice for anyone looking to set up a 24V system. They offer good performance and efficiency once cleaned, and their size is perfect for various off-grid applications. Despite a few minor issues, they have proven to be a dependable part of my solar setup. I believe these would be great for any DIY budget project.

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

The panels are very well made and are interesting, given that they are effectively double sided. I would recommend them to anyone who wants to install them with a solar tracking system (Check out the Eco-Worthy system). Given that my location is in the south west the sun angle is low (78deg in the summer to 31deg in the winter) i am not sure how well the would gather the sun on the rear of the panel. Now i would like to write about the packaging. The panels come from Eco-Worthy well packed and protected but they were delivered by Fed X. It is very clear from the state of the packaged that they were thrown about and every box was damaged! I ordered 8 panels and 2 of them were physically damaged with dents to the surface of the panel and I have had to replace them (Thanks to Amazon).

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.

looks good!!!

I have purchased 4 of these panels with the oldest being 5 years old now. They have a very solid frame, are light weight and have pre drilled mounting holes. The attached mc4 cables allow easy hookup in series or parallel. While pricing on larger panels has dropped these panels work when you have a smaller space or don't need kilowatts in pv voltage. Overall they are a solid little panel. Eco-worthy also offers several mounting options that can reduce need to remove snow in winter by angling the panels.

Solar panel worked very well. I paired this with an Bluetti Eb3a and I was able to get 90 watts input from this 100w panel which is pretty good. Charged the power station from 73% to 100% in around half an hour (this was around 1:00 PM so pretty much peak sun). One note: It took me a couple of minutes to properly align the panel with the sun and had to move it again slightly at the 15 minute mark (it dropped to below 70 watts).

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.
