rdtools.normalization.pvwatts_dc_power¶
- rdtools.normalization.pvwatts_dc_power(poa_global, power_dc_rated, temperature_cell=None, poa_global_ref=1000, temperature_cell_ref=25, gamma_pdc=None)¶
PVWatts v5 Module Model: DC power given effective poa poa_global, module nameplate power, and cell temperature. This function differs from the PVLIB implementation by allowing cell temperature to be an optional parameter.
- Parameters
poa_global (pandas.Series) -- Total effective plane of array irradiance [W/m**2].
power_dc_rated (float) -- Rated DC power of array [W]
temperature_cell (pandas.Series, optional) -- Measured or derived cell temperature [degrees Celsius]. Time series assumed to be same frequency as
poa_global. If omitted, the temperature term will be ignored.poa_global_ref (float, default 1000) -- Reference irradiance at standard test condition [W/m**2].
temperature_cell_ref (float, default 25) -- Reference temperature at standard test condition [degrees Celsius].
gamma_pdc (float, default None) -- Linear array efficiency temperature coefficient [1 / degree Celsius]. If omitted, the temperature term will be ignored.
Note
All series are assumed to be right-labeled, meaning that the recorded value at a given timestamp refers to the previous time interval
- Returns
power_dc -- DC power determined by PVWatts v5 equation [W].
