Depending on your lightning rat of incidence would determine what would work best. I have used Heary Brothers in NY for almost 20 years now check their website out.
They have a device that is called an "early stream emission device" that comes with a lifetime $10 million guarantee policy that you will not take a direct strike. This does not cover surge protection just direct strikes. I have clients at 10,000 ft el that have been in their house with multiple strikes radiating around the house many times and never in 18 years take a strike. The MCG surge systems prevented anything coming in to the house. www.hearybros.com ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - d...@solarwork.com - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 "Responsible Technologies for Responsible People since 1988" P Please consider the environment before printing this email. From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Garrison Riegel Sent: Thursday, June 04, 2015 12:03 PM To: 'RE-wrenches' Subject: [RE-wrenches] Integrating with Lightning Protection Wrenches, Does anyone have any best practice recommendations (or books, articles, etc) for integrating a roof mounted PV system with a lightning protection system? Bare #6 copper and a split bolt to the braided copper connecting air terminals? At both ends of the array? Or should we not bond these systems on the roof? Opinions on a 2009 Wrenches thread varied, but I've heard it from a few sources that these should be bonded directly. Wondering if there is a general consensus at this point? Or strong opinions one way or the other? Thanks for your thoughts.
