<div dir="ltr">Corey - yes, nearby lightning can zorch PV array diodes en masse, and not always all the diodes at once. Provided they are accessible and not potted in epoxy DigiKey can provide replacements. When the module manufacturer has gone out of business, getting the precise specs can be impossible, but there's nothing special about bypass diodes, the usual products should work fine.</div><div class="gmail_extra"><br clear="all"><div><div dir="ltr">Dan Fink<div>Buckville Energy</div><div>IREC Certified Instructor™ for: </div><div>~ PV Installation Professional</div><div>~ Small Wind Installer</div><div>NABCEP / IREC / ISPQ Accredited Continuing Education Providers™<br>970.672.4342<br><br> </div></div></div>
