55 Watt Flexible Solar Panel 12V White Semi-Flex ETFE Solar Panel Charger Off-Grid for Marine RV Trailer Boat Cabin Van Car Uneven Surfaces

This high-performance solar panel has great flexibility, durability, and efficiency, making it an excellent option for use on maritime applications, RVs, trailers, boats, cabins, vans, and even uneven surfaces. This solar panel's adaptability represents a significant step forward in the industry. This flexible panel, in contrast to standard rigid panels, can bend to an angle of up to 30 degrees, making it possible to mount it on curved surfaces with ease. It seamlessly molds itself to the curves of my car or boat, allowing it to collect the most amount of solar energy possible despite the irregular shape of the surface. This versatility allows for the expansion of the possibilities for the production of solar power in atypical settings. As a result, I now have the opportunity to explore off-grid regions without compromising my ability to meet my energy requirements. This solar panel makes use of monocrystalline technology, which is known for its great efficiency. As a result, it is capable of producing an outstanding amount of electricity even in difficult situations. The panel's design features ETFE (Ethylene Tetrafluoroethylene) covering, which improves the panel's longevity and tolerance to adverse environmental conditions. This guarantees that the panel can resist exposure to the elements, including rain, snow, and extreme temperatures, without having its performance be negatively impacted in any way.

Edit 8/10/23- after a couple of weeks of these flat mounted (and after being assured by their customer service that they are indeed safe to do so) I decided to test output from the panels mid day.... Guess what? They COMPLETELY SHUT OFF THROUGH THE BEST SUNLIGHT OF THE DAY. Yep, you read that right. Apparently, they get so hot that they stop producing power at the time of day most would be produced. F'ing ridiculous. I purchased 8 of these and now am going to have to return the lot because they are useless. If a panel can't produce power between 11am and 5:30pm, it's worthless. If you've been considering these, don't waste time and money like I did: look for a better quality panel.Edit 7/28/23- seller does not respond to email inquiries from their website, but did contact me about my review through Amazon, and offer a full refund on 1 of the 8 solar panels I purchased. Upside: a free panel, I guess? Still no clue if mounting these directly to an RV EDPM roof is safe, or could heat up and start a fire.7/24/23- After seeing lots of horror stories online about gluing flexible panels to the roof of an RV, I decided to contact the manufacturer. Last thing I want is my rig catching fire! Unfortunately, there is no way to contact them through Amazon. They state in their product listing that it can be glued to the RV roof, but I wanted to see if there were reservations on that- such as "glued to metal is ok, but not EDPM"

As others have mentioned, the power output for my 100 watt panel seemed low. That being said, I don't think I have gotten any panel, from any manufacturer that has hit advertised spec. .. . . .I got about 3 amps in non ideal sun.. . . .I bet I can get 4 amps in perfect high noon conditions.. . ..The quality and shipping protection is top notch.. . . . .This is my third flexible panel from three different manufacturers and this Alrska 100 watt unit is the highest quality. . . I bought this particular unit because the size was perfect for my application.The panel was 65 bucks delivered. . .. . .. . .Cheap price, high quality for a flexible panel, but possibly low on power output.. . .I'm still happy with it.

I've had this panel running a 12v fridge and charging a 100Ah battery for the last week. I was expecting anywhere in the mid 70% efficiency and in the right conditions and with a high SW sun the panel was able to stay in the 75-80W range while it was 100 degrees outside. Easily keeps my 12V fridge running and the battery topped off as long as I get 4-5 hours of steady sun per day. There are other review's from amazon customers complaining that the panel doesn't produce enough wattage but I wonder if there are other issues at play (an already charged battery) The panel produces what I figured it would depending on the suns angle. 30-50W low angle sun and 60-80W midday sun. I have this panel running through a MPPT charge controller. The panel itself is still fragile. While it is flexible in its long axis, don't expect much movement or flex perpendicular to that. If you do flex it more than 1" that direction you will start to hear little pieces of glass cracking. Just pushing on the panel hard enough with your fingers will cause the glass to start to crack. So the durability is not the best, but I have no comparison if other flexible panels are more durable than this (I doubt it). It is a glass solar panel that is covered in plastic, its not a piece of wood so take it easy when handling it!

Updated review:After my first review. They reached out and offered to send me new panels. I was happy how they handled this situation. After installing the panels on top of my off-road camper, they seemed to be working fine and charging my batteries. HOWEVER, when i took the camper out on my first trip after solar panels installation, it stopped charging when i was driving on a bumpy dirt road. It’s been 3 days and i tried all the troubleshooting methods, I could never get it to work again. I’m very frustrated. After couple hundred dollars and countless hours of installing and troubleshooting, I finally gave up. I would never recommend this product to anyone. Don’t make the mistake i madeOld review:It stopped working after only 5 monthsI bought 2 100 panels and install them on my camper. It works great for about 5 months then it suddenly stopped working. I’m in AZ (if you know what i mean) and it only charging 1-5 w. WTH? Very disappointed
