power_loss_phys {SunsVoc}

Physical Model Power Loss Modes of Single period

Description

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.

Usage

power_loss_phys(init_piv, init_isc1sun, init_prs, degr_row)

Arguments

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.

Value

dataframe containing information about power loss due to various power loss modes for one given period

Examples

df <- read_df_raw(df_wbw,0.02,7)
df_init <- select_init_df(df, days = 21)
init <- p_iv.week(df_init, temp = 30, N_c = 60)
init_piv <- data.frame(V = init$voc_corr, I = init$isc_1sun - init$isc)
init_piv <- dplyr::arrange(init_piv, .data$V)
init_pivf <- ddiv::IVfeature(I = init_piv$I, V = init_piv$V, crtvalb = 0.06)
init_prs <- init_pivf$Rs
init_isc1sun <- init$isc_1sun
df_full <- IVXbyX(df, corr_temp = 30, 60)
power_loss_phys(init_piv,init_isc1sun, init_prs,df_full[1,])
