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

Initial testing on a tabletop outside in direct sun showed all 4 100-watt panels were within the advertised specifications. I measured open circuit voltage, short circuit current, and power output using an MPPT charge controller connected to a 12V battery. I then installed all 4 panels on the pilothouse roof of my trawler (using 3M VHB tape) and the system is working as expected. I will update this review if anything goes bad with the panels, but otherwise no news is good news. Be aware that although these panels are flexible, they are still fragile and you should treat them as such when handling. From some of the reviews, it does not sound as if everyone understands this. "Monocrystalline" should be the key word to let you know they are breakable. If you are careful with them during installation, they will treat you right.

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.

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

Efficient panel at a great price, ordered more after initial installation. Paired it with Victron SmartSolar charger. Have not seen 100W; maximum observed output is 89W from any single panel. That said, this panel has a prismatic surface that appears to focus sunlight at lower angles. My observation is the overall output throughout the day seems better than my other ‘glass’ fixed panels because of this effect. Other points of note: Mounting eyelets ID is small. I needed to remove to use my preferred LOXX fasteners to mount. The wires exits the panel in opposite directions from the ‘box’ on the panel. For my installation this forced me to loop one wire under the panel so I could get both wires to run parallel to each other. Unsure of durability yet. I suspect UV will take its toll over the years but easy to replace as they are certainly priced right. Great value!

Bought one 3 years ago and it has worked well-80 watts. Decided to buy another to hook in series. The picture on the ad shows my exact panel. 3 cells across and 11 down. The new one is a different design 3 cells across and 9 down. The voltage is different and the size is different. So they need to change the picture in the ad. Panel looks very nice. But no series hook up. The new panel has 6 cells less. At .5 volts per cell this panel is short 3 volts. Huge problem in overcast skies, could see zero watts. The real problem is that all the good reviews are for a panel you're not going to get.

unit feels flimsy and is supplied without mounting kit and manual

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.

Super ma batterie se recharge enfin complêtement et mon frigo fonctionne toute la nuit. Suit partit 4 jours avec rien que de la pluie, mais il a assuré la charge malgré ça. Léger souple de bonne qualité livré vite j'en suis très content

Como lo explico? Es decir, me siento muy a gusto con el producto, de hecho ya pedí el segundo, pero desafortunadamente con el primero tuve un problema. Me convencí de dejarlo a la intemperie y justo ese mismo día que fue su segundo día de uso, se presentó un tiempo climatológico desfavorable, a tal punto que el panel salió volando, afortunadamente estaba sujeto a un amarre elástico improvisado, me convencí de que como es flexible no le iba a pasar nada. Cuál fue mi sorpresa? Que al día siguiente ya no daba la capacidad que me estaba aventando que era de arriba de 65w, lo estoy usando con la EcoFlow River 3, pero bueno el asunto es que me asomé como es que estaba dando menos voltaje, lo bajé para revisarlo y me di cuenta que tenía un rayón, por lo que supuse que al estarse golpeando con la escalera a la que estaba sujetado, fue eso que lo afectó. Yo asumo que el error fue mío, pero ahora con el segundo panel ya soy más cuidadoso. Los paneles se sienten de muy buena calidad, no aseguró que den arriba de 70w, porque he venido monitorizando durante mucho tiempo el tiempo real. Pero de que los recomiendo, sí, los recomiendo. Importante saber que para quienes vayan a hacer sus experimentos de unir dos o más paneles, lo hagan en paralelo para que se mantenga en un rango seguro de Amperaje, y es muy importante revisar cuanto soporta su centro de energía, ya que el no tener cuidado sobre eso, podría llegar a dañar sus baterías de almacenamiento masivo de energía. Y si no están seguros de como hacerlo, lo más recomendable es que pidan que un profesional realice dicha instalación. Ah! Una última cosa, para quienes los vayan a comprar, es importante saber que no vienen con sus cables que se conectan al cable de AC y mucho menos trae un cable (Y) ojalá y más adelante puedan considerar proveer ese cable ya que podria sacarnos de muchos apuros, yo al darme cuenta de eso por eso desde el principio pedí mi cable para conectarlo a la extensión. Ah! Y por favor tengan mucho cuidado al comprar una extensión de AC, porque tiene que ser exclusivo para energía solar fotovoltaica, de no ser así si no ponen los cables correctos podrían generar un corto circuito y adiós paneles, cables y baterías de almacenamiento. Es todo, muchas gracias.

Wp max (1 month use) = 110wp Wh in 1 day (may in France) = 520wh On average i get 70-80wp and 400wh on my campervan. Way better ten expected.

Bought this flexible 100W panel to test solar charging at the sailboat. Arrived in good condition, so no complaints. 5 star review at the moment and will update if necessary. Typical solar connectors, so highly recommend to buy a set of connectors and 6mm2 wire. The connector set usually has good enough crimping tool, too. My wiring is not yet as good as it should be, so need to beef up those... On 11th June at 17:00-18:00 still gives 47W and a few amps of charging current. Coupled with a Victron SmartSolar 100/20 and quite happy so far, but let's see how it works during the summer months here in Finland. Planned use is to get some solar power for the instruments and fridge while sailing and anchoring without shore power.

Sto usando questo pannello sul tetto del mio furgone e ne sono molto soddisfatto. È leggero, sottile e si adatta bene alle superfici leggermente curve: l’installazione è stata semplice grazie ai fori di fissaggio, che ho trovato comodissimi anche per un montaggio “rapido” con ventose quando serve spostarlo o rimuoverlo. Prestazioni reali: collegato a una EcoFlow Delta 2 in pieno sole, ho rilevato circa 75 W continui. Per un pannello da 100 W nominali è un valore realistico: tra temperatura, angolo non sempre ottimale, cablaggio e controller è normale non arrivare al 100% della potenza dichiarata. In pratica, ricarica in modo affidabile la power station durante le soste e copre bene i consumi di bordo del mio frigorifero. Qualità costruttiva e praticità: la finitura è pulita e il pannello dà una buona sensazione di solidità pur restando flessibile. I cavi sono già pronti per il collegamento alla power station/regolatore e la gestione è davvero “plug & play”. Sul tetto, una volta fissato con delle ventose, si è adattato perfettamente alle curvature senza mai staccarsi. ATTENZIONE DA NON USARE IN MARCIA FISSATO CON LE VENTOSE. Cosa migliorerei: Sarebbero utili accessori di montaggio inclusi (ventose e viti) Un cavo un po’ più lungo e flessibile farebbe comodo in alcune installazioni (opinione personale)
