Anodized PV frames on copper roof in marine environment [RE-wrenches]

[graham at solarexpert.com]

E H Roy,

There is a beach community in Southern California with over a hundred 
aluminum-framed modules on top of bus stop shelters.  They have been in 
service for a few years and some have brown marine grade paint applied 
onto the frames.  The un-painted modules look much better.  The painted 
modules have a mottled look because the paint is flaking off.  The SM 
modules I have worked with have black frames as opposed to bronze.  
Either way I think they will look great and should hold up well.  I have 
several anodized aluminum fly-fishing reels that have been soaked with 
salt water many times and not cleaned as often as the manufacturer 
recommends, and there is no sign of corrosion.

Siemens has a Power Point presentation about solar power for marine 
applications.  I can send you a copy.  It is a few years old and Siemens 
may have a newer version.

Graham
