This is the most solar power we have ever installed on an Airstream. Our client will be able to run their residential refrigerator and even an air conditioner for a few hours at a time. This is the gold standard for an Airstream power system upgrade and the artistry and technical know-how demonstrated on this job are why AM Solar is typically booked out four months in advance.
The narrow dimensions of our SP100 solar panels make them ideal for the curved roofs of Airstreams. Our adjustable mounting feet allow clients choose if they want the panels mounted level or following the contours of the roof. We replaced the Airstream factory charger with a Progressive Dynamics PD9260 for more gentle treatment of the batteries, which increases their lifespan. At 600W, this is one of the largest solar arrays we have installed on an Airstream.
This rig came to us with two functioning 65W panels and a low-end charge controller. They wanted more power. We added two of our 100W solar panels and combined them all in a roof mount c-box. Instead of penetrating the roof under the c-box, we routed the cables down the refrigerator vent. Because of the two different panel types, with different voltages, we went with a PWM replacement charge controller and added a battery monitor. (MPPT controllers don’t do well with mixed panels). We also added a USB outlet for portable device charging.
