There are several measured types of solar irradiance. • Total solar irradiance (TSI) is a measure of the over all wavelengths per unit area incident on the Earth's. It is measured facing (pointing at / parallel to) the incoming sunlight (i.e. the flux through a surface to the incoming sunlight; other angles would not be TSI). The is a convention.
