I have a 2019 179 which I have mounted 4 Renogy flexible 100 watt panels on the roof and have 2 portable 100 watt Renogy flexible panels. The way I setup my solar array is very controversial and whether to use flexible panels attached to the roof with adhesive but that is the way I set it up. I am happy with the performance of my system. Right now they are covered with snow and just waiting to go to work and go to South Carolina, Florida, and New Mexico in very short order.
By the way there is going to be a Michigan Pod rally up in the Traverse City area June 18 to the 21 if your interested in seeing the mods others have done to their R-Pods, you can find the specifics on the rally under the events tab of this forum
