Angle of Incidence (AOI)

Description

Angle of Incidence (AOI)

Usage

angle_of_incidence(
  x,
  array.type = "fh",
  suffix = TRUE,
  azimuth_Q = "azimuth_Q",
  zenith = "zenith",
  na.val = NA,
  zenith.max = 90,
  AOI.max = 90,
  verbose = getOption("merra2.verbose"),
  ...
)

fAOI(
  x,
  array.type = "fh",
  suffix = TRUE,
  azimuth_Q = "azimuth_Q",
  zenith = "zenith",
  na.val = NA,
  zenith.max = 90,
  AOI.max = 90,
  verbose = getOption("merra2.verbose"),
  ...
)

Arguments

x
array.type
suffix
azimuth_Q	the solar zenith angle, degrees
zenith	the solar azimuth angle, degrees
na.val
zenith.max
verbose
...

AOI = \arccos\big(\cos(zenith)\cos(array.tilt)+ \sin(zenith)\sin(array.tilt)\cos(azimuth-array.azimuth)\big) Though the equation returns AOI values with any given set of zenith, azimuth, array.tilt, and array.azimuth, the AOI is meaningful only if \mjseqn0 \leq zenith \leq 90, and \mjseqn0 \leq AOI \leq 90. The former condition assures the sun is above the horizon and the latter condition assures the sunlight beam is able to hit the panel (Source: Stackhouse et al., 2018).
