Solar Panel Performance vs Panel Tilting

Unless you are going to have a tracking system either automatic or manual, I suggest you set your tilt for the latitude in which you live. You won't get max current all the time, of course.

The perfect system would automatically track the sun all day long, but that means a complex system with motors to drive the panels. In addition they would have to be de-deployed when the rig is not in motion.

I like that you did the research and provided the charts.
