JA11.2 System Orientation
JA11.2.1 Prescriptive Compliance
PV systems or strings with module pitches greater than 2:12 or 10 degrees shall be installed with azimuth range between 90 to 300 degrees measured clockwise from true north. PV systems or strings with module pitches smaller than 2:12 or 10 degrees can be installed with any azimuth range.
JA11.2.2 Performance Compliance
When the California Flexible Installation (CFI) 1 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.
When the CFI2 is selected in the performance calculation, the PV array shall be installed with an azimuth range between 105 to 300 degrees from true north, and with all modules at the same tilt as the roof for pitches up to 7:12.
If the PV array does not meet either CFI1 or CFI2, then the actual orientation of the PV array shall be described.
