The term analog is stupid because PV gear (unless is has a digital display) is ALSO or actually more analog by definition. You don't say a fire is analog. A lightbulb is not digital just because it goes on and off; neither is PV gear. An electric guitar is analog for example, but so is an acoustic guitar because it is producing sine waves. But you don't call an acoustic guitar an analog guitar In comparison BECAUSE AN ELECTRIC GUITAR ISNT DIGITAL.
because It is semantically incorrect, is why the term should not be used. I could get into a discussion on binary, what sine waves are, etc, but I hesitate to because most people cant seem to grasp the concept that a lightbulb is an analog circuit.
