Hello Jim D. I'm very late to the party but plan to do, this summer, what you have likely done by now; also to a 2001 410. I'd like to know what you eventually settled on assuming that you did install the panels? Please attach pictures if you can.
I'm looking to mount two larger rigid panels; 285 to 315 watts each. To do this I am intending to mount two approximate seven foot lengths of 1" round stainless tubing, attached at the forward end to the traveller arch and extending aft past the bimini top and cockpit enclosure. I will build an arch of 1" round SS attached to either the base of the traveller arch or to the transom which will run up to and behind the bimini and to which the two lengths of tubing coming aft from the traveller will 'T' into. I will attach the panels, one each, to the two 1" SS tubes with four lengths of 1" square SS tubing attached across the panels, and these attached to the round tubing with four tubing clamps each. I think this will be a relatively simple yet structurally sound means to attach the panels. I hope to run the wiring within the traveller arch and fit the controller and monitor at the nav station, below.
