(poa_global, wind_speed, temp_air, model='open_rack_cell_glassback')[source]¶ Estimate cell and module temperatures per the Sandia PV Array Performance Model (SAPM, SAND2004-3535), from the incident irradiance, wind speed, ambient temperature, and SAPM module parameters.
- Parameters
poa_global (float or Series) – Total incident irradiance in W/m^2.
wind_speed (float or Series) – Wind speed in m/s at a height of 10 meters.
temp_air (float or Series) – Ambient dry bulb temperature in degrees C.
model (string, list, or dict, default 'open_rack_cell_glassback') –
Model to be used.
If string, can be:
’open_rack_cell_glassback’ (default)
’roof_mount_cell_glassback’
’open_rack_cell_polymerback’
’insulated_back_polymerback’
’open_rack_polymer_thinfilm_steel’
‘22x_concentrator_tracker’
If dict, supply the following parameters (if list, in the following order):
- afloat
SAPM module parameter for establishing the upper limit for module temperature at low wind speeds and high solar irradiance.
- bfloat
SAPM module parameter for establishing the rate at which the module temperature drops as wind speed increases (see SAPM eqn. 11).
- deltaTfloat
SAPM module parameter giving the temperature difference between the cell and module back surface at the reference irradiance, E0.
- Returns
DataFrame with columns ‘temp_cell’ and ‘temp_module’.
Values in degrees C.
