After reading what others have done to mount a rigid solar panel, mostly involving some sort of swing arm, and trying a temporary fixture myself, I found what is for me an easy, tidy solution.

I've relocated my rigid 20 watt solar panel (it has a metal frame) on the weekend to my stern rail, simply by using the kettle barbecue clamp available at most chandleries. It's better than a normal two-part rail clamp in that it has a lever to tighten and loosen, and no tools are required to move or remove the panel once the clamp is installed. Another neat feature is that both sides of the part that clamps onto the rail are captive, so that you don't wind up losing one half in the drink.

All I had to do was bolt a cross bar in the middle of the back of the panel, then bolt the rail clamp to it. It was a half hour job from whoa to go, and works great!
