Dave, thanks for the reply.What are your thoughts when you see (in various publications and/or websites) solar PV distributers and even "module" manufacturers using the term 'panel' to describe a 'module'? benn DayStar Renewable Energy Inc. benn@daystarsolar.ca780-906-7807 HAVE A SUNNY DAY

The NEC is pretty clear that the basic building block for a PV system is a module, the complete unit. Assemble some of these together & now you have a panel. (This is less common now that we have 250 watt modules and not 50 watt modules.) An array is defined in the NEC as a mechanically integrated unit; I tend to think of an array as all of the modules on site. They added a definition for a subarray in the 2011 NEC; this is an electrical subset of an array.

Which term do you believe to be correct and why? My interpretation is that a single framed unit is a module. Any number of modules attached to a single detached 'rack' is a panel, and a group of panels with the same orientation or mounting location/type is an array. If you agree with my interpretation, what are your thoughts on the widespread use of the term 'panel' to describe a module. thanks, benn DayStar Renewable Energy Inc. b...@daystarsolar.ca 780-906-7807 HAVE A SUNNY DAY _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org David Brearley, Senior Technical Editor SolarPro magazine NABCEP Certified PV Installer ™ david.brear...@solarprofessional.com Direct: 541.261.6545 Fax: 541.512.0343 Visit our Web site at solarprofessional.com (Sample copy available for download at: solarprofessional.com/sample) _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
