Hi Darren,
For SAM's Detailed Photovoltaic model, each case in SAM supports up to four subarrays, so it is not possible to define shading scenarios for more than four subarrays.
Depending on the system you are modeling, you may be able to use the Combine Cases macro to represent the system, as described in this post:
sam.nrel.gov/forum/forum-general/1540.
UPDATE: As of SAM 2021.12.02, the Combine Cases macro is replaced by the Calculate generation profiles and nameplate capacity from open cases option on the Power Plant page for the Generic System model and Generic Battery model. See the SAM YouTube channel for a
short tutorial
