Dave, thanks for the reply.<div>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'? <div>benn</div><div><br><span class="ecxecxecxecxEC_Apple-style-span" style="color:rgb(0, 32, 96)"><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">DayStar Renewable Energy Inc. </font></span><div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">benn@daystarsolar.ca</font></div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">780-906-7807 </font></div><div><font class="ecxApple-style-span" face="'Franklin Gothic Medium'">HAVE A SUNNY DAY

<font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size:11pt">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. <br>

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? <br>
Which term do you believe to be correct and why?<br>
<br>
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.<br>
<br>
If you agree with my interpretation, what are your thoughts on the widespread use of the term 'panel' to describe a module.<br>
<br>
thanks,<br>
