how to account for the dc and ac ohmic loss when using pvsystem.Array and pvsystem.PVSystem ?

[saikatghosh90]

array_dcoutput = pvsystem.Array(mount=sat_mount,modules_per_string=module_series, albedo= albedo, module_type= module, strings=total_strings,
module_parameters=cec_module,
temperature_model_parameters=temp_model_parameters)

how to use - pvlib.pvsystem.dc_ohms_from_percent ?

You would use both pvlib.pvsystem.dc_ohms_from_percent (first) to calculate the resistance, then pvlib.pvsystem.dc_ohmic_loss to calculate the power loss (in W). dc_ohms_from_percent requires an input dc_ohmic_percent, and returns the resistance needed for input to dc_ohmic_loss. We haven't set a default for dc_ohmic_percent because this is relatively immature and not well documented as a model. The PVsyst default value is 1.5%.
