pvanalytics.quality.irradiance.daily_insolation_limits#
- pvanalytics.quality.irradiance.daily_insolation_limits(irrad, clearsky, daily_min=0.4, daily_max=1.25)#
Check that daily insolation lies between minimum and maximum values.
Irradiance measurements and clear-sky irradiance on each day are integrated with the trapezoid rule to calculate daily insolation.
- Parameters
- Returns
True for values on days where the ratio of daily insolation to daily clearsky insolation is between daily_min and daily_max.
- Return type
Series
Notes
The default limits (daily_max and daily_min) have been set for GHI and POA irradiance for systems with fixed azimuth and tilt. If you pass POA irradiance for a tracking system it is recommended that you increase daily_max to 1.35.
The default values for daily_min and daily_max were taken from the PVFleets QA Analysis project.
