Larry was interested in my solar mounts and others might be as well so figured I'd post this publicly. Briefly, I installed (2) 75-watt solar panels on each rail back in 2003, and have been very pleased with them. They typically provide 80-100 AH or more per day, less in rainy weather of course. When not needed they fold down and give a bit of privacy for the cockpit, like lee cloths. I crossed the Atlantic with them with no problems. If really severe weather was expected, they could be removed by undoing the 4 U-bolts holding them to the rail.
Hopefully the pics are fairly self-explanatory. I replaced the top lifeline with rigid SS tubing. Aluminum angle-bar runs along the inboard edge of the panels and holds them together. A similar aluminum angle-bar runs along the outer edge - this one almost the entire length of the panels to support the outer edge. Four SS flat bars run across the panels; each of them is drilled for a U-bolt which holds the panels to the rail.
I added a strut, as well as an extra vertical stanchion, to help support the rail.
To raise the panels, or adjust their height, I have a PVC tube sliding inside another PVC tube. The inner tube has a series of holes drilled in it. A SS pin is placed through a hole depending how high you want the panel.
