(module_temperature, poa_global, deltaT, irrad_ref=1000)[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].
\[T_{C} = T_{m} + \frac{E}{E_{0}} \Delta T\]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
