pvdeg.degradation.vecArrhenius

pvdeg.degradation.vecArrhenius(poa_global: ndarray, module_temp: ndarray, ea: float, x: float, lnr0: float) → float

Calculates degradation using \(R_D = R_0 * I^X * e^{-Ea/(kT)}\) :param poa_global: Plane of array irradiance [W/m²] :type poa_global: numpy.ndarray :param module_temp: Cell temperature [°C]. :type module_temp: numpy.ndarray :param ea: Activation energy [kJ/mol] :type ea: float :param x: Irradiance relation [unitless] :type x: float :param lnr0: prefactor [ln(%/h)] :type lnr0: float

Returns:

degradation (float) – Degradation Rate [%/h]
