pvpumpingsystem.pvpumpsystem.calc_efficiency

pvpumpingsystem.pvpumpsystem.calc_efficiency(df, irradiance, pv_area)

Computes the efficiencies between PV array output and motorpump output, between irradiance and PV output, and global efficiency.

Parameters:

• df (pd.DataFrame) –

  Dataframe containing at least:

  electric power ‘P’ flow-rate ‘Qlpm’ total dynamic head ‘tdh’

• irradiance (pd.DataFrame) – Dataframe containing irradiance on PV
• pv_area (numeric) – Suface of PV collectors

Returns:

Dataframe with efficiencies

Return type:

pandas.DataFrame
