CIE 241:2020 – Recommended Reference Solar Spectra for Industrial Applications (89 pages)

This document cancels and replaces CIE 085-1989 “Solar spectral irradiance”.

This document provides CIE recommended reference solar spectra for industrial applications. It contains a large selection of simulation benchmarks for total, direct and diffuse components of solar spectra under various atmospheric conditions and solar geometries (defined by the air mass). For this purpose a freely available solar spectral irradiance model has been used to generate tables and figures of solar spectral irradiance under a number of different atmospheric conditions, in the form of explicit meteorological input parameters. The data as provided in this document are to a large extent comparable to those in CIE 085-1989, but they are presented with a higher spectral sampling. The respective solar spectra are the basis for national and international standard reference spectra for various applications. They have been extensively validated against measured spectra.
