The Global Tilted Irradiance (GTI), also known as the Plane-Of-Array (POA) irradiance, is the total hemispherical solar irradiance incident on a titled plane. It has SI units of W m−2. It is the sum of the beam, diffuse and ground reflected irradiances incident on that same tilted plant.
To include the relevant formulae
- hemispherical integral of radiance for GHI, DHI, GTI
- integral of radiance from the extents of the solar disc and circumsolar region, for BNI (differentiate between BNI from the solar disc, and that of measurment instruments)
- differentiate between spectral and broadband values
Radiative transfer in the atmosphere
[edit]
- the relevant interactions as the solar radiaiton traverses through the atmosphere for the component in question
- for the GTI the ground reflectance needs to be considered as well (with links to Lambertian vs non-Lambertian scattering)
