pvsyst_celltemp(poa_global, temp_air, wind_speed=1.0, eta_m=0.1, alpha_absorption=0.9, model_params='freestanding')¶
Calculate cell temperature using an emperical heat loss factor model as implemented in PVsyst.
The heat loss factors provided through the ‘model_params’ argument represent the combined effect of convection, radiation and conduction, and their values are experimentally determined.
poa_global (numeric) – Total incident irradiance in W/m^2.
temp_air (numeric) – Ambient dry bulb temperature in degrees C.
wind_speed (numeric, default 1.0) – Wind speed in m/s measured at the same height for which the wind loss factor was determined. The default value is 1.0, which is the wind speed at module height used to determine NOCT.
eta_m (numeric, default 0.1) – Module external efficiency as a fraction, i.e., DC power / poa_global.
alpha_absorption (numeric, default 0.9) – Absorption coefficient
Heat loss factors to be used.
If string, can be:
- ’freestanding’ (default)
Modules with rear surfaces exposed to open air (e.g. rack mounted).
Modules with rear surfaces in close proximity to another surface (e.g. roof mounted).
If tuple/list, supply parameters in the following order:
Combined heat loss factor coefficient. Freestanding default is 29, fully insulated arrays is 15.
Combined heat loss factor influenced by wind. Default is 0.
temp_cell (numeric or Series) – Cell temperature in degrees Celsius
