It was different, not necessarily better...
I thought you (and others) might like to see the difference in the connections. I think our connectors and angle give us a bit more latitude in panel adjustment than the flat on the roof style usually used.
For us, it was the only solution, and has worked well for (almost) ten years.
I was pretty excited about solar power then. I still am. Trailer, now our home, eventually our sailboat, too, will run independently on quiet, nonemitting solar. We're still working on best way for a sailboat. Sails tend to shade everything...
And, thank you for all the information and work that you put into your post. As always, so very helpful to others.
