pvdeg.degradation#

Collection of functions for degradation calculations.

Function Overview#

pvdeg.degradation.IwaArrhenius

Function to calculate IWa, the Environment Characterization [W/m²].

pvdeg.degradation.IwaVantHoff

IWa : Environment Characterization [W/m²] For one year of degredation the controlled environmnet lamp settings will need to be set to IWa.

pvdeg.degradation.arrhenius_deg

Calculate the Acceleration Factor between the rate of degredation of a modeled environmnet versus a modeled controlled environmnet.

pvdeg.degradation.degradation

Compute degredation as double integral of Arrhenius (Activation Energy, RH, Temperature) and spectral (wavelength, irradiance) functions over wavelength and time.

pvdeg.degradation.vantHoff_deg

Van't Hoff Irradiance Degradation

pvdeg.degradation.vecArrhenius

Calculates degradation using \(R_D = R_0 * I^X * e^{\frac{-Ea}{kT}}\)
