About solar dish stirling system was created by hamza.allouhi
Hey there,
1- I want to know the details that SAM adopt for the shading factor calculation of solar dish stirling system , because it was mentionned in the help that: ''SAM's approach to modeling shading is different from the Osborn approach described in the Fraser thesis.''
2- I hope to have more clarification regarding the following parameters (Dish Stirling => Solar field=> Array Shading parameters):
    -Ground Slope, North-South (%)
    -Ground Slope, North-South (%)
    -Slot Gap Width (m)
    -Slot Gap Height (m)

Best Regards,
Allouhi Hamza

Dear Allouhi Hamza,

SAM 2020.2.29 is the last version of SAM to include the Dish Stirling model. We are no longer supporting that model in SAM.

You can see the Dish array shading calculations in the source code here:

Best regards,
Paul.
