pvdeg.humidity.front_encapsulant(rh_ambient, temp_ambient, temp_module, So=None, Eas=None, Ead=None, encapsulant='W001')[source]#

Calculate diffusivity weighted average Relative Humidity of the module surface.

Parameters:

rh_ambient (series (float)) – Ambient outdoor relative humidity. [%] Example: 50 = 50%, NOT 0.5 = 50%
temp_ambient (series (float)) – Ambient outdoor temperature [°C]
temp_module (pandas series (float)) – The surface temperature in Celsius of the solar panel module “module temperature [°C]”
So (float) – Encapsulant solubility prefactor in [g/cm³] Will default to 1.81390702[g/cm³] which is the suggested value for EVA 001 if not specified.
Eas (float) – Encapsulant solubility activation energy in [kJ/mol] Eas = 16.729 [kJ/mol] is the suggested value for EVA.
Ead (float) – Encapsulant diffusivity activation energy in [kJ/mol] Ead = 38.14 [kJ/mol] is the suggested value for EVA.
encapsulant (str) – This is the code number for the encapsulant. The default is EVA ‘W001’.

Returns:

front_encapsulant (pandas series (float)) – Relative Humidity of the photovoltaic module frontside encapsulant. [%]
