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

My second panel. Excellent price and love the bifacial. Its light weight and seems ready to be mounted. I haven't mounted mine yet as I am experimenting with a box design to focus light on the backside of the panel like winter would and simulate winter all year in Colorado. I feel like these panels are durable and hope they last through the summer as they will be put to the test during hail season which is about to start. Highly recommend if you want to see some improvement to just a single pane panel. I see on average about .2A to .8A per panel more on a cloudy day than just my suitcase panel. On a super sunny day I can say from my calculations of what I consider ideal is about 60-80 watts per panel. That's pretty good folks if you think about the controller also sucking up some of this energy and there had to be some loss through where I'm measuring which is at the terminal where the cable connects to the junction box. Love solar power and want to help others too. This panel rocks and pick one up while the price is still low. This brand eco-worthy is one of my favorites and I own a bunch of their stuff and they all work well. Excellent performance and the mc4 connectors are attaching and detaching well with my custom made cables and other pre made mc4 cables.

It works great

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.

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 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
