RNG-50DB-H

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

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.

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.

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

I’ve just put this on my pop topcamper but the positive cable is only about 4 inches long I don’t get why renogy would not put a longer cable so on a pop top you can feed underneath and easily connect cables underneath where it’s dry and better fot a wire connection. .very strange.

Cables need to be longer they are both different lengths

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.

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/
