Mounting solar dis simmilar metals issue

[stevensuf]

Ok I am in the process of mounting some solar panels, made a frame up off the transom was in the process of mounting the first panel then thought mmm solar panel aluminium frame, ss316 arch....

Can anyone tell me how much of an issue will this be, being that they are not in the water?

Well it is obviously an issues BUT most people seem to manage fine IF this is a major concern to you get some NOA Mounts (alloy mounts with a hard rubber sleeve that goes over the rail and does more than 'just' insulate the alloy from the S/S rail.........but then you need to get alloy or nylon nuts and bolts as if you use S/S ones you are going to have the same problem as a direct S/S mount.

We are using Scandinavian NOA solar panel mounts (expensive but great) that allow us (and we do) to tilt the panels towards the sun.....after sunset we try to remember to flip them over for the morning dawn sun......saves getting out of bed at 05:30.

If you are that worried about it, use a thin barrier on the mounting points (something like thin plastic - cut up a milk jug, or set up a film of caulk) and Tefgel or equivalent on the bolt threads. No big deal.

I think what your after is called Duralac paste, which prevents/reduces the problem. Which reminds me I need to do the same thing on my solar panel, another trip to the chandlers.
