On my 15 Anthem, the OEM solar was two 100W panels and a controller. I think that it is the same at least until 2019 and I think currently.
Little more than keeping batteries topped off if the coach is in the sun.
757Driver has done the full solar conversion and will most likely come on here. You can believe what he tells you.....
