I am validating a preliminary rooftop PV system design for a potential client and found something that I haven't had to consider before. Their preliminary design calls for a 128-cell PV module with a rated Voc of more than 90 V. Given the requirements of NEC 2017 690.12 that the conductors inside the array boundary be limited to not more than 80 V, can this module be installed on the roof of a building? I have reviewed all the relevant information I could find from the manufacturer, and it doesn't give any indication one way or the other, though the only promotional photos I've seen of these particular modules have been ground-mounted systems.
Thanks.
Thanks.
