Angling solar panels to the sun is not a panel technology issue, it is simple physics. The benefit has not changed. It is true that some panel manufacturers make use of internal reflections, back side generation, and such, it makes a VERY small difference in overall output if the panel doesn’t track the sun.
When the sun is at 45 degrees the panels only “see” about 70% of the incident solar radiation they do when at 90 deg. What they don’t “see” they can not generate power from. That’s physics and hasn’t changed.
The hard part is deciding if it is worth it to mount adjustable angled panels on a moving platform like an anchored sailboat. I don’t have an easy answer for that one...
