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

Message body


People in and out of the industry misuse the term PV panel all the time. 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.

Wrenchers,



Which term do you to describe a single framed unit with either a j-box or two 
wire leads on the back, module or panel? 

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,
