Thought this may be of interest:
I have mounted two 85 watt Suntech solar panels across the davits, by using two 2" x 2" aluminum angle strips, fixed to the davits with "U" bolts. I am going to add a center support, but have not done this yet; and the panels are not wired up yet.
This shows the relation of the solar panels on the davits, and the "U" bolts securing them; the vertical pole of the hoist and the two support brackets on the rails of the stern seat; and the outboard mount, on the same rails.
