The panels perform well seem durable and are flexible. I’m very pleased with them. They fit the bill for my application. Small amounts of shade do not seem to significantly impact the panels’ output, unlike some i’ve used.I needed low-profile flexible panels to fit on my truck’s topper, between the roof racks. The size of the panels are a perfect fit, and allow 2 to be installed on my roof. I wanted the installation to be easily removable, but to also easily handle highway speeds without me worrying about panels flying off. Utilizing the grommets on the panels allowed me to use M6 tee nuts and M6 machine screws and 1” M6 threaded plastic knobs to hold the panels in place. The grommet placement on the 2 panels I received were identical. I fit the machine screws through holes drilled in the topper. The screws (and large washers) are on the inside of the topper, with the tee nuts on the outside. The screws and nuts are snugly tightened, which allows the plastic knobs to be loosened and tightened without someone inside the topper holding a screwdriver to keep the screws from loosening. I used RTV to seal the holes, which also helps hold the screws and nuts in place without turning. I’ve used similar combos on truck toppers for 30+ years and have never had water leaks.I also attached heavy duty velcro around the edges of the panels, and attached velcro to the topper. The velcro alone holds the panels very well, but I wanted more security for highway speeds, hence the tee nuts and machine screws. I also put a “carbon fiber” looking vinyl wrap on the topper where the panels fit, for abrasion protection. Insulation can be placed under the panels to insulate the topper from the panels, which can get hot. 5 mm foam insulation is what I use.

Performs very well I use it to restore my lithium solar battery and to run a fridge while camping

I was going to mount two of these on my trailer. However, they weren't as flexible as I thought they would be. Ultimately, one of them would not flex enough to go on the trailer, which would have left me with only a single 50 watts panel, which in turn would have not been enough power. I ended up sending them back.From a structural standpoint, I think they would be pretty durable. However, realize that you have to have pretty gentle curved surfaces if you are trying to mount them on anything except a flat surface. In retrospect, they might have been stiff enough to be used as portable solar panels that could be leaned against the trailer during the day and put away each evening.

The solar panels were protected during shipping with foam bumpers in a sturdy cardboard box. They feel sturdy and tough. They tested out at 198 watts each, as advertised. I have no qualms about mounting these on my sailboat and exposing them to the elements. These are well designed and engineered solar panels.

Ordered 3 panels for my Sprinter Camper, as per Renogy installation instructions glued then to the roof of my van. Output was low to start but I live in MN so wrote it off to less Sun. Went to California for 2 months, output has dropped even more, 3 panels in parallel in bright clear sunshine are producing less than 5 amps. Bought two cheap Harbor Freight panels, layed them on top of the Renogy panels, the cheap panels are over 10 amps with just two of them, exactly what they are rated at. Talked to tech support, rather I tried but everytime the tech was supposed to answer they hung up, called back 5 times same thing every time. I then went to email, after a couple day wait for a response they asked me to do some tests and send some pictures and video. I did as asked. Another couple day wait,, Then wanted followup video of the lights on the controller. Another wait and they sent a group of photos showing me how to do the same tests I had already done, with examples that weren't even the same panels I have. I got the distinct feeling I was being run around in the hope that I would just go away. I've been an electronics tech for 50 years, had my own shop for 45. I will never buy another Renogy product and advise everyone else not to as well. It's my own fault for ignoring the negative reviews, I hope all of you are wiser !Update: Renogy has told me they would take the panels back, minus 10% plus I am responsible for shipping on thier defective product. I asked them how I am supposed to remove the panels THEY told me to glue on to my roof, according to Renogys installation instructions, without damaging the panels or my roof. They haven't responded yet.
