pvlib.temperature.sapm_cell_from_module#
- pvlib.temperature.sapm_cell_from_module(module_temperature, poa_global, deltaT, irrad_ref=1000.0)[source]#
Calculate cell temperature from module temperature using the Sandia Array Performance Model.
See [1] for details on the Sandia Array Performance Model.
- Parameters:
- Returns:
numeric, values in degrees C.
Notes
The model for cell temperature \(T_{C}\) is given by Eq. 12 in [1].
(1)#\[T_{C} = T_{m} + \frac{E}{E_{0}} \Delta T\]The module back surface temperature \(T_{m}\) is implemented in
sapm_module()
.Model parameters depend both on the module construction and its mounting. Parameter sets are provided in [1] for representative modules and mounting, and are coded for convenience in
