I just finished installing two 100-watt Obsidian panels on the roof of our Escape 5.0 fifth-wheel fiberglass trailer. They are great! They're light, relatively small, produce electricity as expected: (8 amps total in my real-world conditions) well made, and are somewhat easy to mount.
One concern I have is the extra cost required when mounting panels on a roof that is not perfectly flat and horizontal. The panels each come with four mounts, all the same height. My trailer's roof slopes ( and I'll bet yours may too). But Zamp wants about fifty dollars for kits with mounts of different heights, either higher or lower. Some kits don't even come with mount bases. Fifly bucks is a lot of money you'll need to factor into your solar panel budget if you buy these panels. Why not give a cost break to people who purchase a panel if they need to swap mounts?
I also want to comment on Zamp's decision to use their new "ATP" wiring connectors instead of the older SAE "Zamp connectors" that have often come preinstalled on new RVs. These new ATP connectors seem to be Deutch DTP series 2-way connectors, environmentally sealed, waterproof electrical connectors designed for the transportation industry. I like the connectors and bought the tools and parts to build my own cables. I installed Zamp's ATP inlet on the rear of my trailer so I can also connect my Zamp portable 90-watt panels. So far, so good. Ed Simmers
