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.
