pvdeg.degradation.vecArrhenius#
- pvdeg.degradation.vecArrhenius(poa_global: ndarray, module_temp: ndarray, ea: float, x: float, lnr0: float) float[source]#
Calculates degradation using \(R_D = R_0 * I^X * e^{\frac{-Ea}{kT}}\)
- Parameters:
poa_global (numpy.ndarray) – Plane of array irradiance [W/m^2]
module_temp (numpy.ndarray) – Cell temperature [C].
ea (float) – Activation energy [kJ/mol]
x (float) – Irradiance relation [unitless]
lnR0 (float) – prefactor [ln(%/h)]
- Returns:
degredation (float) – Degradation Rate [%/h]
