I have continued to brainstorm this solar panel placement problem and have tentatively decided to replace the old 75watt seimans panels that fit between two stanchions with 135 watt kyocera. My concern is that the 135s are about 15 pounds heavier and they will stick up over the top of lifelines. Do you think the stanchions will be able to withstand supporting a 30lb panel? Has anyone tried this with larger panels like this? Ive seen plenty with 80 watts or so on the stanchion but never noticed a 135 in that space.
NiftyNickers, do you have a picture of your arch that you could post? I am interested in having something fabricated here in the states that I could take down and install myself on my boat in mexico. Thanks for your response.
