Hi all,
When running SAM with an X-concentrated PV cell array, I get this crazy behavior every day at solar noon. The Plane-of-Axis (POS) drops to zero W/m2, and thus kWh production does the same. It's almost as if there is a shadow cast over the tracking cell at precisely solar noon. (please see screenshot below).
Can anyone explain why this is happening, and how to get rid of it to accurately model daily output?
Many thanks!
