<div dir="ltr"><div><div>William<br></div>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<br></div>Jerry<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Aug 31, 2015 at 12:22 PM, William Miller <span dir="ltr"><<a href="mailto:william@millersolar.com" target="_blank">william@millersolar.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div link="blue" vlink="purple" lang="EN-US"><div><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial","sans-serif"">Friends:</span></p><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial","sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial","sans-serif"">I thought I had sent a message about this to the list but I believe not.
