Guys I would like to install 3 Kyocera 130 Watt panels at a weight of 75 lbs total. My boat has a nice SS 1" tubing bimini /arch which is a permanent welded structure. Essentially there are three 1" down tubes on either side that are fixed to the deck with associated cross bars the beam width of the boat -14'. It is a virtual SS cage arrangement. Seems to me despite all this, the 75 lbs of panels will for structural purposes be supported by the 3 down tubes on either side and their associated cross bars (which again bridge the beam of the boat). The panels once mounted will bridge over all three of these cross bar arches . I have tried Googling and engineering sites re the bending strength to of the 1" SS but no luck. Any structural engineers types out there who can render an opinion as to whether there is sufficient strength in the three SS 1" arches to support the panels???? Sorry if this is less than clear.
