The panel I have is one of these: https://www.amazon.com/gp/product/B00R8SMVC2 which isn't "marine grade" but it was relatively cheap and for my use it won't be deployed in the weather all the time so I hope it will last a few years.
I mount it with zip ties to the top of the dodger, which has webbing loops in the right places for the zip ties. I left the wires long enough that I can move it around to a clear location when the dodger is shaded. When the weather is wild or in the off season I store it under the v berth mattress. It doesn't roll up, just flexes a bit, hence "semi-flexible".
It connects through a jack in the cockpit to a charge controller, which connects to the house battery bank. You need a separate charge controller as the voltage from these panels isn't usable as it comes right off the panel, and to get the most efficiency charging your specific battery chemistry.
I measured it carefully while using it at Princess Louisa Inlet last time I was there and it completely offset our electrical use from the hours of about 10:00 AM to 6:00 PM, meaning the battery state of charge was the same at both of those times despite heavy use (from the fridge) in between.
I said 19v because I thought that's what I remembered. I also thought it was 14 amps just from memory.. (keep in mind I did this 2 years ago)
This is the actual stats,
Peak-power: 120W
VPM(V):18V
Maximum current(A):6.66A
Voc(V):23V
Isc(A):5.52A
Maximum system voltage(V):1000V
Cell type:Sunpower solar cell
Output Interface:MC4 connector
Dimension:46.121.2*0.14 inches
So the max Amps is actually 19.98 meaning the 20 AMP CC is fine. I just can't expand it, for some reason I thought I could.
These are the panels I used..

I've been running my system for 2 years now.
