View source: R/tpk-power_loss-phys.R
This function decouples power loss to different loss modes, specifically current mismatch, recombination, uniform current loss, and Rs loss, from the changes in IV features for a given period, used internally for power_loss_phys_bat function.

|
init_piv |
Dataframe containing current andvolatge psuedo-IV curves of initial period, calculated from the the result of p_iv.week function applied to timeseries dataframe of initial period. |
init_isc1sun |
1 sun isc generated from the p_iv.week output from the initial period dataframe. |
init_prs |
extracted rs from the psuedo-IV curve of the initial period. |
degr_row |
one row of output from IVXbyX function. |
dataframe containing information about power loss due to various power loss modes for one given period
