It is possible to have a super solar system on an Airstream by careful selection of the components from a vendor like AM Solar.
We have eight 100 watt AM Solar panels on the roof of the 2014 Classic 30 feeding into a TriStar 60 MPPT charge controller housed inside the cabinet behind the dinette with a vent fan for cooling. The Magnum MS-2800 charger/converter resides under the sofa where the factory converter was formerly installed. The factory battery box is now the home for the Titan disc brakes controller and electronics. A custom stainless steel battery box is on top of the frame between the propane tanks and the trailer body housing four Lifeline 6Vdc 300-amp hour batteries.
We did install a new primary circuit breaker box under the street side twin bed to handle the large (15,000 BTU) living room air conditioner, the AC electrics for the refrigerator and water heater and a 30 amp 240Vac breaker feeding into the Magnum MS-2800. When shore power or the generator is not in use, the Magnum continues to feed the original circuit panel from the batteries. All the 120Vac outlets both inside and outside of the trailer, the microwave and small air conditioner remain in the original panel and are capable of operation all the time (well not the air conditioner as it draws too much power from the batteries for extended use).
We did also install the Maxim skylights to head off that problematic leak prone area and put the FanTastic should over their fan. Since a lot of the interior furniture was in temporary storage, we had other customizations done at the same time
Photos of the installation and other modifications to follow after I get the trailer back home to Arizona.
