I haven't seen anything practical that swivels up with say a motor. My raised panels are just below the ACs. ie Sun on the panels only occurs when the sun is less than 10 degrees elevation. ie From a practical standpoint no RV shadows of concern.
Possibly your considering adding to the current panels. In 2014, I started from scratch and considered and ignored any post that didn't make sense and they were a lot related to raised panels. A easy upgrade for me would be to change the 60 cell panels for 72 cell panels resulting in up to 350W per panel. And there are other options.
