Solar Ele on the roof or remote?
I understand that AS now installs wiring for solar, even if the solar option is not chosen. So, solar panels can be added later. When installed later, should they be installed on the roof, using AS's wiring or separate from the body of the AS?

The factory pre-installed #10 wire is just barely adequate for the two 53 watt panels that Airstream installs on the roof.
We were able to install five 100 watt panels on the roof a 23D and eight on the roof of a 31' Classic. Nine would have fitted okay.
The wire sizes were significantly larger from the roof to the solar charge controller like #2 wire.

Your choice. Dozens of threads discussing this subject.

Here is how we are installing five 100 watt AM Solar panels on the roof of the 23D. We replaced the original Winegard fold down TV antenna for the Winegard Rayzar (curb side front). We have replaced the factory skylight with a frosted lenses skylight from Maxim. The two Fantastic fans were replaced with two Maxxfan model 00-07000K units.

So, how did you connect it to the ele system? You couldn't have used the existing wire because it would be in adequate.

Can the panels be tilted toward the sun?

All AM Solar panel kits come with rocker mounting feet that allow for tilting in either direction. If you intend to use the tilting feature, you have to give a bit of thought about the panel placement to avoid shading one panel when you tilt another.
When connecting the panels to your battery system, heavy cabling (up to 2AWG) feeds the roof array into the solar charge controller and then directly to your batteries. The only place 10 AWG cabling is used is to connect the individual panels to a combiner box.
Switz is totally correct in that Airstream' pre wire is completely inadequate for any solar array in excess of 100 watts. Connecting the solar charge controller directly to the batteries is also much more efficient and shows less voltage drop than using the forward bus bars, as Airstream does.

I took delivery of a 2016 25 FC in June. My dealer also has a significant AS restoring business and knows all the trailers inside and out, they also install solar, as an option, on many of their customers new and restored AS.
I had TWO Samlex 100 watt panels installed. They too said they would not use the AS pre wire, too small, and they pulled their own wiring to specifications of the load.
I am pretty ignorant when it comes to electrical designs and specifications but I am glad I listened to the Airforum experts since I am comfortable my dealer was not jerking my chain.
Thanks forum experts! We listen:-)

So, one wire is routed on the outside of the shell down to the batteries?

Outside ?????? NEVER!!!!
All wiring is invisibly run thru the inside of the trailer. The only outside wire is from the front DC bus bars to the exterior battery box, where it is located from the factory.
In the majority of my installations, new batteries, either Lifeline AGM or our new lithium cells are placed inside the trailer, so no external wiring is used.

I saw a video of a couple that do a blog of their life on the road in a SOB. They installed 4, 100watt flexible panels that were only about 1/8th an inch thick. Looked really nice only screws were for the wiring not the panels.

I never use screws for my installations. If you search the Forums, I gave posted some direct usage comparisons between hard panels and flex panels.
There are many issues with flex panels that the promoters don't disclose.

Interesting. The commercial and recreational marine industry has been using flexible panels successfully for over 30 years. Some people here act like they are a new untested undeveloped product. I have several 25 year old flexible panels that still put out almost as good a new. Labels are long time gone and I do not remember what brand they are.

The photos in post #4 above of the solar panels on the roof of the 23D were pre-wiring as we were still testing the layout. The wiring was completed last week and the solar panel wiring combiner box was to be installed just above the microwave which is above the refrigerator. That is in the free space beside the street side of the air conditioner.
The pair of #2 stranded copper wires come through the roof below the combiner (or junction) box to the solar panel controller located behind the microwave and then continue downward inside the trailer to the solar system isolation switch located in the refrigerator compartment. The solar wires then proceed to the lithium iron phosphate battery located under the "sofa" just in front of the street side wheel well. The Magnum MSH-3012 is located on the other side of the furnace so the leads from it to the battery are about three feet.

How were they fastened to the roof?

You would be well served to get a but of solar education here: http://www.amsolar.com/home/amr/cpag...education.html

The wiring that comes with AM solar's kits is great. And I used Lew's advice to upgrade some of the other sections of wiring in my setup. The only thing lacking for me currently is batteries, but I'm going to soon resolve that.
