SAM Snow Model with Ground-Mount PV System #1547

Description

@shelbielwickett

Is your feature request related to a problem? Please describe.
I would like to run a snow simulation (Marion Model) in SAM for a ground-mount PV system.

Describe the solution you'd like
The snow model in SAM uses 1.97 as the snow slide amount coefficient. For a ground mount, Marion suggests 6 as the snow slide amount coefficient. I would like the option to use 6 instead of 1.97.

Describe alternatives you've considered

Used pvlib as alternative.

Additional context

See page 2-3 for SAM documentation on the Marion Model: https://www.nrel.gov/docs/fy17osti/68705.pdf
