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

I bought the 2x100w semi-flexible 9bb panels. They were delivered fast. I had never heard of Topuvine, but the panels seem pretty good, and it seems the company in China is a player in the market of solar, so I took a chance because of price. Most of the reviews were Vine members, and not technical enough except one review that was spot on. The packaging was adequate, and panels were not damaged. I tested them quickly in evening sun with them in series, and saw about 165w from them. Mounted them on camper using sikaflex and corrugated pvc panel cut into 3/4” strips spaced ~5” apart. I liked the semi flexible feature, not too bendy, not too stiff, and especially liked the length of cable provided with the MC4 connectors. The best part. Just got back from camping. See attached screenshot, I got in traffic, had good midday sun, 80f temps, and the 2x100w panels in series where providing 208w at 15a out of the MPPT controller. My shunt shows I saw 210max!!! I was rolling between clouds too! So now the question is longevity. Will the coating deteriorate fast, develop hot spots etc, or will the panels just gradually lose their performance over the years. I’ll be back to update next year.

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.

These are a bit stiffer than other flexible panels I've seen but that's fine for my application which doesn't require bending to fit a surface. I've got them hooked up in series feeding my RV. The charge monitor is showing 13v @ 10 - 10.5 amps when in full sun. The power drops off considerably with any clouds or shading. All as expected for a solar panel and it matches the performance of my rigid HQST 100 watt solar panels. The surfaces of this seem pretty tough and have a texture that looks like coarse woven fabric. I guess that helps to shed dirt? Pretty happy with these so far. I'll update as necessary. I dinged one star for the tiny grommets used. The only thing that fits through them is a zip tie.

These things are tough. I did a poor install and the wind ripped it off my roof at 70mph on the highway. Several vehicles ran it over in the road but it still works fine.

I had 4 of these that i purchased a year ago and they’ve been serving me well. I just bought 2 more and they aren’t the same. They have only 9 columns of segments, compared to 11 in the first lot i bought. The segments are exactly the same size so these new panels are significantly shorter. Doing the math, these new panels have about 80% of the surface area of the older ones, yet everything else seems to be exactly the same design - so how can these also be 100W each? I’d return them but as a full-time vanlifer i had to get these delivered during a hotel stay, as they’re too big for Amazon locker, and it’s expensive/difficult to arrange delivery of new panels. I will update this if the power output seems to be comparable. UPDATE: yeah these new panels are utter crap. Installed 4 weeks ago and they are already starting to delaminate. The old ones which have been on for over a year are not showing any signs of delamination - last pic is the new panels where you can see bubbles. 2nd UPDATE: The new version panels are a different voltage to the original. The listing still states the original max power of 19.1V. These are NOT 19.1V anymore - they are now 15.9V - see product labels in pics. They are not compatible for connecting in parallel with the older model. They may also not be very effective at charging, depending on the charge controller you use (my controller requires at least 5V difference between battery voltage and input voltage in order to charge, which just won’t happen with these new panels if you connect in parallel). Wasted hundreds of dollars on these panels, troubleshooting, and put unnecessary holes in my vehicle roof.

I put 4 of these on my car * UPDATE: I have achieved a high of 408 watts with 4 100 watt panels. So these can achieve more than 100% although I generally only get 350 watts or so. And about 25 watts in thick clouds. I'm super pleased.

great price, and produced up to 80watts each when laid in the driveway

The product is awesome, the best flex panel that I've bought. In spring sun, I got 224W max out of a 200W pair in series. In summer conditions I get ~180W. Not deformed even after almost a year in the sun(ambient can get to 35C, in a long 4.5 months blazing hot sun), very thin but sturdy. I recommend.

Soddisfatto, peccato per la giornata uggiosa. Amplierò l’impianto 💪🏼

Top Qualität

A voir dans la durée,le matérielle ne me parrais pas de qualité exceptionnel mais a voir sous les UV

Vendu comme des panneaux 100 watts mais ne produisent que 50 watts en crète ! Esseyé sur un autre panneau et 2 autres marques, : même probleme : ce ne sont pas des 100w mais des 50w, merci d'etre plus honete sur la description. A part ça ils sont bien.

Slecht product. 100W paneel in volle zon = effectief 30W. Schande dat ze zoiets verkopen.
