No PV systems or strings with module pitches greater than 2:12 or 10 degrees shall be installed outside of the azimuth range between 90 to 300 degrees measured clockwise from true north. If the PV array does not meet this orientation requirement, then the actual orientation of the PV array shall be described in the performance method.
When the California Flexible Installation (CFI) is selected in the performance calculation, the PV array shall be installed with an azimuth range between 150 to 270 degrees from true north, and with all modules at the same tilt as the roof for pitches up to 7:12.
