ECO-WORTHY195 Watt 12 Volt Monocrystalline Solar Panel Module Off Grid PV Power for Battery Charging, Boat, Caravan, RV

I am mounting four of these on cargo roof. When they arrived one box was a bit ragged, but all worked. These are light enough for me to get up on roof (I'm 68). They are just the right size to fit on 2 five foot (10 foot cut in half) superstrut channel tapped to roof of cargo trailer. Mounting in a 2S2P configuration to two 40 amp mppt controllers (making it easily expandable to 2S3P system. Will run my AC off grid. These are the best value unless you order solar panels by the pallet. This cargo trailer is my hurricane emergency kit.

Over the last 2 years, I have purchased 12 of the 195W panels and installed them in 3 groups of 4 panels. I also purchased the 4-up brackets that EchoWorthy sells (3 of them). All panels arrived well packaged (one had some superficial tears on the outer package. The panels are pretty rigid and don't weigh much. They're light enough that I installed the brackets and panels myself, with no help (2 hands). The output has been high and pretty consistent with their claims/labeling. I recently experienced 90 mph straight line winds that caused the long steel piece (joined in the center by a smaller/thinner steel piece and bolts) to bend. All panels continued to work. to repair the issue, I dis-assembled and re-enforced the long center steel (on all 3 of my groups of 4 panels not just the bent one). No panel experienced individual damage visibly or with output. The panels have also survived several South Dakota hail storms with no visible or output damage. 2 Years later, I am still happy with my purchases, and would choose this brand over others because of my good experiences. I have no criticism of the solar panels. They work well. My only criticism is of the brackets, and it's very minor - the center steel assembly design needs to be beefed up for some regions of the country/world. I think in 90% of places, the design will work great. If you're handy enough to put the system together yourself, you're probably handy enough to beef the center piece your self too.

I have ordered a few of these off amazon and they all shipped differently and from different warehouses. One of them that was supposed to have come from Illinois via UPS never made it, it got lost and I had to do a return. The one from Pennsylvania made it, but it was shattered and I had to do yet another return. Amazon was kind enough to not ask me to ship the shattered one back but they would not send a replacement, only a refund and I would have to re-order is since they "already did a return less replacement". Since I bought it during Prime day I got a good deal and since I had to re-buy it afterwards it cost me more. The last one that I ordered came by UPS and although the box was damaged the panel was fine. They look nice and work good. They can be ordered directly from Eco-Worthy for less as they do not charge tax and have better discount codes.

Somewhere along the line both boxes were punctured in a number of places. One was ripped open at a corner and it looks like the panel was dropped and hit hard on that corner. There is a very noticeable dent. These panels are rock solid and the damage is only cosmetic, the panel is fine otherwise.These are not the most powerful (wattage) but the smaller dimensional size makes them easier for me to work with and fit in the space available. They're also more expensive, there are larger (watts and physical size) panels available at less cost but do not include shipping and the ease of return provided by Amazon.The seller DCHouse has also been responsive to my many inquiries. Overall I am very happy with the multiple transactions I've made with them.

Image 1 - nearly charged batteryImage 2 - low charged battery due incorrect load settings on another controller, it drained way too low when the load was only a 12 volt dashboard voltage meter.Image 3 - 3 100 watt panels showing darn near 300 watts total. It get cold in the winter. No need to get fixated on the name assigned to the controller.Not sure what this industry i thinking, but I pay twice as much for 195 watt panel and get half the advertised current. 195 rated max watts and testing 100 watts at 4,000 feet altitude and clear sunny day in the Nevada desert. What conditions are you basing your ratings on? Panels on the International Space Station?Maybe my testing equipment is bad, but it shows 1/3 the advertised ISC. The Victron controller shows 100 watts coming in at 6 amps. The Victron does throttle based on its algorithms for battery SOC, or so it appears. For that reason I posted two images reflecting a nearly charged battery and a discharged battery.Picking up the panels the sound of stressed glasses crackling is loud and clear, even though there are no signs of broken glass. Concerned about longevity.One panel was completely shattered. One has a frame ding but not shattered. Not feeling so great about 6 panels being handled by my local UPS, as they are a gaggle of lackluster folks who do very little to handle or deliver properly. Not EcoW's fault.BougeRV 200 watt panels are equally misrepresentation of watts and current. They measure about the same as these. While my 3 100 watts panels darn get 300 watts with rated current.Overall, my experience with the higher rated panels = RIPOFF

After testing and re-testing, this panel functions amazingly well, it's a good bang-for-the-buck.I do have a slight issue getting the negative MC4 plugged in, just have to use a little elbow grease.Great bargain, and good output. I am surprised at the output in fact, normally you can not expect but around 63-65% of a panel's rating (sometimes, in really good conditions ~75%, depending on the design), but this panel pushes out a consistent 68-73% of it's rating in good conditions. It's a better deal than many of the panels in this output range, on Amazon.
