Equipment and contruction diagram for making a solar arch, plus ideas for improvements that you could use in your design.
There are lots of things to consider when creating a solar system for your Bavaria yacht, weight was one of our key factors, another was where we could mount the arch
Arch
This we mounted on the back of the yacht using the hard point at the back and another fixing point on the rear of the boat. We used Seascrew to buy all the bits, and below is the list of all these items.

In this design there are various pieces, C - Corner, T - T pieces, 60D - 60° Deck fitting, 60P - 60° pipe fitting, SP - Swivel Pipe fitting and SD - Swivel Deck Fitting. TD is a T Piece, but it goes down towards the deck, while TA are the additional T pieces we should have bought for the cross pieces.
Although you should measure the pipe for your boat, we used the 2 x 3m lengths to go across our boat, the 2 x 1.5m lengths to be the 60° pipe, the 2 x 2m lengths to be at the back of the design, down onto the transom and we cut the three of the 1m pipes in half to make the top and the other two 1m pipes were used to make the side bracing
Apart from the cross braces that we should of added into our design, the other improvement that we should of designed in was the position of the P clips and the bolts. If we had done it right we would of cut the 1m pipes that went between the long lengths on the top of the arch so that the bolt that went through the P clip went through the Solar panel as well. We did not do this so we had to screw the bolt into a piece of wood and screw the panel down into the same wood while trying to avoid the other screws.
