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.
