William LUMUS makes a glass on glass frame-less module, they say to use there racking but give them a call and see i don't have a email for them so google away good luck. BTW we work also very close to the ocean and we sometimes get salt build up on the micro inverters but i have not seen any corrosion on the modules nothing big anyway, are all the modules grounded to earth because like boats there is a discharge that can cause damage to the metallic parts and if there is not a good ground or one with either positive or negative voltage or charge excessive damage can result in electrolysis Jerry
