Renogy Solar Panel 100W 12V Lightweight Ultra Flexible Black Division Monocrystalline Bendable Mono Off-Grid Charger for RV Marine Boat Van Car Curve Surfaces, LTWT-Flex

Update May 2025: I reached out to Renogy and they have shipped me a replacement panel, no hassle. This is in line with what I have experienced from Renogy in the past: solid customer service and decent product.- - - -Would be two stars because this was listed at a low price since it was a seller return. I should have known better than to buy a customer return. I just got around to looking closer at it today (when I'm outside the return window) and 12 of the 36 cells are delaminating, or at least full of bubbles. I have been a Renogy customer for years and have several of their more-expensive products like a 48V 3500W Solar Inverter Charger, and have been generally happy. But now I am profoundly disappointed that Amazon passed on this defect to a customer on Renogy's behalf.

Fantastic quality. I bought an adapter cable and connected a cable a solar guy made me that plugged right into my Goal Zero Yeti 1500x and I am good to go without paying the Goal Zero prices for their proprietary solar panels.

Product looks great. Box received with one side opened and never had been taped so I don’t know if paperwork came with it. No papers in box. Looking forward to using it

I'm running 4 200w alongside 6 100w panels. Efficiency is almost 10% lower compared to hard panels however it fills the niche on the RV roof. An RV roof is the main issue. Your never fully in the sun, never fully directed, and the AC's can add shade issues.Although it's a poor panel from an efficiency standpoint, I am still giving them 4 starts because it's better then the alternatives for this application (CIGS is probably better but it's still cost prohibitive). Renogy customer service is pretty good also - They replaced 2 panels after 4 months - one for an output issue and the other for a broken connector.Most reviews say that these are too fragile but I have to disagree. If you bend it too far then I'm sure it would break but I have had no issues. They bend all over during the install and I also re-positioned them twice now without any trouble. Just be reasonable - flexible does not mean foldable.

Very good

So far so good. It is not as flexible as I though but that is fine with me. I have it in the back window of my car and it fits perfectly. Along with the Bluetooth solar controller I purchased this one panel is enough to provide a maintenance charge during these cold months.

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.

Installation was a breeze. The panels are perform well so far.
