Personally, I wouldn't want marketing people to read the NEC unless all of our customers were reading the NEC, too. The reality is, when talking to customers, a module is called a panel. When talking to you, a module is a module. In customer speak, panel is to module as features are to specifications. Panel is a softer word.
I have been known to scold a salesperson for mixing up power and energy, though.

But the term PV panel is also used so ubiquitously in place of the term PV module-both in common parlance and in the industry-that it's probably going to supersede the terms in the NEC over time. Since the NEC terms were defined when modules were 50W each, one could make the case that a 250W module bears some resemblance to a panel, as originally conceived. One new company that does know the difference is Solyndra. Each cylinder in Solyndra-speak is a module. They refer to the field-installable assembly is a panel. Technically perfect use of the terms. My personal pet peeve is not keeping power and energy straight. We can all distinguish between between miles-per-hour and miles. So how come some people in this industry can't keep kW and kWh straight? That smells fishy to me, especially in "technical sales" literature.
