pvpltools.module_efficiency.fit_bilinear#
- pvpltools.module_efficiency.fit_bilinear(irradiance, temperature, eta)[source]#
Prepare a bilinear interpolant for module efficiency.
This function allows the class pvpltools.iec61853.BilinearInterpolator to be used in a way that is compatible with other efficiency models in this module.
- Parameters:
irradiance (non-negative numeric, W/m²) – The effective irradiance incident on the PV module.
temperature (numeric, °C) – The module operating temperature.
eta (numeric) – The efficiency of the module at the specified irradiance and temperature.
- Returns:
interpolator – A callable BilinearInterpolator object
- Return type:
Notes
Unlike the other efficiency models, bilinear interpolation only works with a regular grid of measurements. Missing values at low irradiance high temperature and vice versa are filled using the method described in [1] and [2].
