pvanalytics.features.snow.get_irradiance_imp(i_mp, imp0, irrad_ref=1000)#

Model effective irradiance from maximum power current.

Assumes a linear relationship between effective irradiance and maximum power current, i.e., Eqn. 8 from 1.

Parameters

  • i_mp (array-like) – Maximum power current at the resolution of a single module. [A]

  • imp0 (float) – Short-circuit current at reference condition. [A]

  • irrad_ref (float) – The reference irradiance used to determine imp0. [W/m2]

Returns

effective_irradiance – Effective irradiance. [W/m2]

Return type

array-like
