These clients like to travel around the country with the goal of avoiding hot weather. They are headed for Alaska for the next several months, and on their way, they stopped by to have solar power installed to offset some of their electrical usage. We installed 400W of solar power on their roof, and the majority of their system control components were installed under their bed. This Airstream came with a Zamp portable solar panel plug, which they wanted to be integrated into the solar system we installed. We set up this system with expansion in mind, so if they find that 400W isn’t enough to offset their light DC loads, they have the option of using a portable panel, and/or they could choose to install up to another 200W on their roof.
