Ground Irradiance was created by Daniel Marshal

Hi all,

in SAM 2022.11.21, there are new updates about output for ground Irradiance. Can I get equation refference for this output. I checked the PV Technical Refference ( www.nrel.gov/docs/fy18osti/67399.pdf ) but can't find the related equation.

nb: Following variable that I mention as ouput :
- Irradiance incident on the ground within array
- Irradiance absorbed by the ground within the array
- Array POA rear_side radiation reflected from the ground after (IAM)

Thanks !
