August, We're currently working on a SolarPro article on this topic. It will appear in SP4.3 (April/May 2011). As usual, there are a fair number of changes that impact PV installations. Our authors have done a good job, in my estimation, of pointing these out, discussing the implications, & providing the reasoning behind the major changes. Should be a good introduction & overview of the Code changes that impact PV installers.
Also, starting with the 2011 NEC, Mike Holt is addressing Articles 690 & 705 as part of his "Understanding NEC" series. Look for his title, "Understanding NEC Requirements for Photovoltaic Systems." Looking forward to getting my hands on a copy, David Brearley, Senior Technical Editor SolarPro magazine NABCEP Certified PV Installer david.brear...@solarprofessional.com Direct: 541.261.6545 On 1/13/11 10:35 AM, "August Goers" <aug...@luminalt.com> wrote: > Hi All - > > > > My shiny new copy of the 2011 NEC handbook just came in the mail and I've > started reading through it trying to decipher what changes we should be > expecting in the future.
