Methods for irradiance calculations#

pvsystem.PVSystem.get_irradiance(...[, ...])

Uses the irradiance.get_total_irradiance() function to calculate the plane of array irradiance components on the tilted surfaces defined by each array's surface_tilt and surface_azimuth.

pvsystem.PVSystem.get_aoi(solar_zenith, ...)

Get the angle of incidence on the Array(s) in the system.

pvsystem.PVSystem.get_iam(aoi[, iam_model])

Determine the incidence angle modifier using the method specified by iam_model.
