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`.
