Usually, yes, and it's not a 150' X 150' maximum, it's a maximum of 150' in any dimension.Is the 150 ft X 150 ft maximum pv array size also required on flat commercial roofs? Looking at the code and it is listed under residential code.

NYWhich jurisdiction?
I don't have the code in front of me, but IIRC it says 150' in any dimension. Also IIRC, it merely says "the array" must conform. I wouldn't design a system where the racking made it break the rule.A 150'x150' square has a diagonal of 212'. Does that dimension matter at all per this rule?
Also, does it matter if parts of the racking system bleed outside of the 150 ft limit, as long as the modules themselves are limited to 150 ft?

CalFire requirements are not code required in NY. It's generally accepted as a best practice, and many tacking manufacturers will require breaks at 150' for thermal expansion and contraction.
