2PCS 100W 12V Flexible Solar Panel 9BB Monocrystalline Cell 12 Volt Semi-Flexible for Marine RV Trailer Boat Cabin Van Car Uneven Surfaces 12V 24V Battery Charge

Its been 1 year and so far so good. I have 4 panels in a Series+Parallel config and I regularly get 300w, in rare cases have seen 330w, so 75-82w per panel. Can't complain about that! I also have 2 Renogy panels which perform at the same % of power under the same conditions. I worry about the longevity of these, as it appears that some cell clusters are darker/lighter when you view them at an angle (see picture). Maybe that's normal, or maybe there is some UV fading, only time will tell. But no drop in output yet.I like that these are low amp (6.6 Isc) so I can run them in parallel and stay under my 15A limit. Low Voc (18.6) means I can technically run 3 in series and stay under the 60V limit of my power station. I've tried running 3 in series (in hot weather, so not calculating for low-temp voltage) and they work but sometimes I've gotten nothing when I connect the wires, so I don't know if there was a bad connection or maybe the stated Voc is slightly higher and maxing out my unit. I need to figure that out as I might get 2 more panels and run a 3+3 S&P config.The weight and size to wattage ratio of these is excellent. I got them to go on my van conversion, but when I'm not traveling I take them off and put them on a homemade rack to offset my home electricity. This light weight setup means I can easily move them around the yard by hand to keep them pointed directly at the sun throughout the day. Good purchase and would buy again.

Getting good production even with partial shading at 50deg north latitude in September. It has tiny transparent domes like little bumps all over the sun facing side of the panel and they seem to gather scattered light from all directions and improve with shading. At least they seem to compared to other panels I've been trying out side by side with this one in the same conditions.

As other have mentioned these may not quite be 100W panels. I had size constraints that limited my use of larger 100W panels. In direct sunlight I was pulling 200+ watts with 3 solar panels and renogy PWM controller this past weekend with the panels taped to the top of my square drop trailer.The panels are light and I was able to trim the sides a smidge to fit my application. I'd buy them again.

Nicely constructed solar panel that is somewhat flexible. I plan on using two of these on the roof of my crew cab 2500HD truck to power a solar generator I built. I do worry that the backs of the panels get hot so I may place a barrier between then and the roof of the truck. My solar controller says they are pushing watts so I am happy. Power output seems to be about what I would expect, and my battery (2 50AH Lithiums in parallel) fully charge up each day after 8 hours of 5AH breathing machine so i am happy.

The listing shows specifications with a VMP of 19.1V and an IMP of 5.24A and photos show a panel with 33 cells.The new panel is stickered as 15.9 vmp 6.3a and has 27 cells. The resultant product has some issues to say the least.1) Peak production is around 80w in conditions that my 100w reference panel will perform as rated. On its own I might not have even docked a star for this considering the overall value and low weight of the panel2) 15.9 vmp is problematic... like way more than you would expect. Most standard mppts require the operating voltage of a panel to be +1v of the battery charge voltage, and 12.8v lifepo4 batteries charge at around 14.6v. This leaves 0.3v of wiggle room before efficiency starts to tank. And you lose voltage as a product of high temps or as the result of overall cable length. This panel can totally fail to function with fairly mild voltage reducing factors.3) that vmp continues to be problematic with some power stations. Jackery uses 16v as their threshold to determine if they are in car or solar charging mode. My jackery 240v2 refuses to properly track with this panel and gets 7 watts. I didn't miss a zero, I mean 7. I do get more like 70-80w on some other power stations but the 16vmp causes a lot of weird issues and inconsistency4) The fact that the listing was not updated to reflect this change is my main reason for rating this 3 stars. If the listing had been accurate I would have avoided it due to the low vmp on the new panel design. I've included an image of the current listed specs and an image of the panel sticker in the event that the listing gets fixed for the sake of posterity.

I can't speak for the long term use but I got them and hooked them up to my ecoflow delta 2 . First I used the ecoflow panels then hooked up these and they made exactly the same power. So far very happy with them I ended up buying another
