RNG-50DB-H

Have been using this panel for whole of summer charging a 200ah 12v domestic battery bank on our touring motorhome. I have wired an option of linking the domestic battery bank with the vehicles cranking battery, when the vehicle is merely being stored (so, in storage, panel is providing very adequate float voltage charging to a 300ah bank). The solar panel has provided good efficient back up charging, exactly as I wanted, despite being only 50w. Panel simply attached to roof of motorhome using good quality adhesive/sealant. Being the thin flexible solar panel, rather that heavy framed versions used on our narrow boat, there has been virtually no strain placed on the the thinnish aluminium alloy roof panelling of our elderly motorhome. One criticism would be the very short leads provided - a need for purchase of required extending leads. Have used framed solar panels on our boat for years, and very pleased to have now used flexible solar panel on our motorhome. Would recommend.

Flexible and easy to use, you do need a control box to give your required output. Solar panel voltages and current fluctuate.

The 12v fridge on my boat is a necessity and is on 24/7 which means that it is a near constant drain on the batteries consuming up to 40Ah per day. Using two of these 50w panels on a very sunny day in June I can achieve nearly 7A per hour, so in under 10 hours replace all that the fridge needs. Based on this I'm considering adding another 100w to allow for a similar gain in less sunny conditions. The panels are simply laid flat on the curved steel roof secured by steel wire and strong magnets which don't touch the panels.

Great product but just bare in mind - any solar energy is seriously diminished when you put the panel behind glass.

Not sure what went wrong here, but the panel I received was of exceptionally poor quality. Received well packaged, however for one the sealant job was poor (fixable), there was also sealant all over the surface of the panel (fixable), but then there was white globs all under the skin of the panel itself as shown in four of the pics attached, these were NOT on the surface. Alignment also seems off in places. Refunded, and Amazon collected free of charge next day. I'm sure Renogy are usually fine to go with, they have a good name to themselves, reviews seem very good, but personally I'm not prepared to order again and cross my fingers hoping I receive something decent.

Cables need to be longer they are both different lengths

Works well, charges my battery as advertised

Got these for my boat wanted to connect them together for my 24v system so i just wanted 2 small 50W panels. These are so big they are almost the same size as my 100W panels i already have. Thinking about refunding these are ridiculous. They are also like a grey black not black on the cells so i think mine maybe have some other issues as well due to this. i might just send them back they are absalutly massive with no need to be so big/

Pannello 50 Watt buona qualità e prezzo..testato come voltaggio senza carico,alla finestra senza sole 16 volt Il giorno dopo con sole velato 26 volt Quando arriverà l "alimentatore generatore di carica vedrò il collaudo finale per ora tutto OK

Die Lieferung erfolgte in einer recht großen und flachen Kartonage. Im Lieferumfang befinden sich das Solarpanel und eine Anleitung. Wir haben zwei Mal die Variante mit 50W gekauft. Das monokristalline und biegsame Panel hat eine Maximalleistung von 50W. Wir nutzen beide Panels in einer Reihenschaltung auf dem Vordach unseres Hauses. Uns waren die Abmessungen und das geringe Gewicht besonders wichtig. Etwas merkwürdig ist die Tatsache, dass wir zwei ähnliche, aber eben nicht identische Panels erhalten haben. Die Leistungsangaben sind identisch, aber die Abmessungen und das Gewicht unterscheiden sich geringfügig. Ein Panel ist rund 5cm breiter, 3cm kürzer und 0,05kg leichter. Das ist für uns ok, da man die Panels auf dem Vordach nicht sieht, aber so etwas sollte grundsätzlich nicht vorkommen. Das Anschlussterminal sitzt auf der Oberseite und verfügt über MC4 Steckverbindungen. Die Kabel sitzen links und rechts. Wer die Panels, so wie wir, nicht verklebt, kann die Befestigungsösen in den Ecken nutzen. Wir betreiben beide 50W Panel an einem Hoymiles Wechselrichter. An einem sehr sonnigen Tag Anfang Mai haben wir bei nahezu horizontaler Montage Werte um 80W erreicht. Das liegt unterhalb der Leistungsangabe, ist aber zu einem sehr hohen Grad der fehlenden Ausrichtung/Aufstellung zur Sonne geschuldet. Die Verarbeitung der Panels ist gut. Die Herstellung erfolgte in China. In Summe ein kompaktes und funktionales Solarpanel.

I've ordered and tried a good few different solar panels now, from I've tried the top-solar, couple of chinese brands, and this was the only panel that actually got anywhere close to the quoted Watt. On a average day i got 45watts of the quote 50 watt panel. The 2 chinese brand i got about 30watts from a quoted 100watts, the top-solar was 35.

Be sure to test before you install your panel, mine was completely dead. I ordered another as they were half price and it worked perfectly, they seem well made and very durable so I am looking forward to alot of use out of it. Renogy support is very helpful and I recommend there products,

The Renogy Flexible Solar Panel is an excellent option for anyone who needs a reliable, flexible solar panel for off-grid use. I purchased this panel for my RV, and I have been extremely impressed with its performance. The monocrystalline semi-flexible design allows it to be easily installed on uneven surfaces, and the 50 watt output is more than enough to power all of my devices. The panel is also lightweight and durable, which makes it easy to transport and use in a variety of different settings. I love that it's designed specifically for marine, RV, cabin, van, and car use, which means that it's perfectly suited to my needs. Overall, I would highly recommend the Renogy Flexible Solar Panel to anyone who needs a reliable and efficient power source for off-grid use. It's an excellent investment that will pay off in the long run.
