We will be installing 3 100W solar panels on the roof of our new 86 Dolphin. Panels are 47"x21".
Each panel comes with 4 brackets and each bracket has 2 holes. It means drilling 24 holes if I go simple way. Seems kind of a lot. Any alternatives?
Maybe I could get two aluminum rails and install them parallel with just 4 holes in total. Then mount the panels on two rails.
How do you find the best place to drill in the roof? The top layer of the Dolphin roof is aluminum, or am I wrong? Maybe somebody can advice what is the sandwich of the roof? Is it wooden beams-plywood-aluminum?
Thanks a lot for any advice.
