(aoi, dni, poa_sky_diffuse, poa_ground_diffuse)[source]¶ Determine the three components on in-plane irradiance
Combines in-plane irradaince compoents from the chosen diffuse translation, ground reflection and beam irradiance algorithms into the total in-plane irradiance.
Parameters: - aoi : numeric
Angle of incidence of solar rays with respect to the module surface, from
aoi()
.- dni : numeric
Direct normal irradiance (W/m^2), as measured from a TMY file or calculated with a clearsky model.
- poa_sky_diffuse : numeric
Diffuse irradiance (W/m^2) in the plane of the modules, as calculated by a diffuse irradiance translation function
- poa_ground_diffuse : numeric
Ground reflected irradiance (W/m^2) in the plane of the modules, as calculated by an albedo model (eg.
grounddiffuse()
)
Returns: - irrads : OrderedDict or DataFrame
Contains the following keys:
poa_global
: Total in-plane irradiance (W/m^2)poa_direct
: Total in-plane beam irradiance (W/m^2)poa_diffuse
: Total in-plane diffuse irradiance (W/m^2)
Notes
Negative beam irradiation due to aoi \(> 90^{\circ}\) or AOI \(< 0^{\circ}\) is set to zero.
