Spectrum Explanations

AMO (Air Mass Zero) = standardized sun light spectrum outside the earth atmosphere.

AM1.5 (Air Mass 1.5) = standardized sun light spectrum, applied for terrestrial PV applications. It is also called AM1.5G as G stands for global and includes direct and diffuse radiation.

AM1.5d (Air Mass 1.5d) = standardized sun light spectrum, applied for terrestrial CPV applications. D stands for direct and includes direct radiation only.
