Rear mismatch model
A flat rear mismatch, or one calculated from the rear cell rows
What it is
Selects how the rear mismatch loss is found: flat, the rear mismatch loss of this section as a fixed fraction; deline_2020, the fraction Deline and co-workers fitted to the spread of the irradiance across the rear cell rows, calculated every timestep from the cell rows of the rear model; or none, no rear mismatch, as in PVWatts version 8. The Model tab's Rear mismatch step sets it.
Typical values and how to get it
Flat with a measured or datasheet fraction. deline_2020 with a rear model that computes the cell rows: bifacialvf (Marion 2017) or bifacialvf 1° sectors. If not given: flat.
