clamp on the top of the light pole.
This allowed the bowed tubing to rotate in the clamp, and if it was slid up/down, to "tilt" in the clamp as well. It must take some good engineering to make the tolerances tight enough for a solid fit, but loose enough to allow the movements when the clamp is loosened. Since it was "up there" I couldn't see the details of it, but apparently it can be done that elegantly.
How often did they climb up there to readjust the solar panel every day? LOL
Since that mount requires a rather large change in panel location to change panel elevation and there are cables
involved, I'd have to say a simple vertical pivot at the mounting point with a horizontal axis tube clamp is much simpler, just like the satellite
dishes use. Plenty of azimuth and elevation adjustment, with no change in cable position or length. Same principal with our monitor
stands. X and Y axis runs through the center of the monitor
, they can tilt and pan in minimal space without pinching the cables
