A little pricey I think
Yes it pivots, folds and twists, but it is a little pricey for what you get. If money is no object and you've got a ketch rig or limited mounting space it makes sense. We added an arch with integrated stern rails, dingy davits, radar mount, windgen mount, propane tank mounts etc for about $3000. We don't pivot our panels, we are usually off playing most of the day and I've seen people pivot panels and then wind or current changes the orientation and they get nothing. We now run 460 watts on a flat mount above bimini (aluminum angle icon from home depot) and haven't plugged in once in 4.5 years of cruising. We even leave the boat for weeks at a time with the fridge and freezer running without problems.
I also think the rail mounted wings are another option although take a real good look at the potential shading effects. Our bimini blocked them most of the time when we added two more panels to the rail. Plus boarding wave smacks could easily take out the panels if they were not protected.
