本文件提供了一个适当的参考光谱辐照度分布，用于确定太阳热、光伏和其他系统、组件和材料的相对性能，其中需要直接或半球辐照度组件。本文件提供了一个参考半球辐照度光谱、一个参考直接法向辐照度谱和171个附属半球倾斜辐照度频谱。本文件中的参考光谱辐照度定义了空气质量1,5太阳光谱辐照率，用于需要参考光谱辐射度的太阳应用中，对于直射法向辐射5,8°视场和赤道面上的半球辐射，37°倾斜平面上的反照率对应于轻沙土。参考光谱辐照度旨在代表理想的晴空条件。中提供了代表不同天空条件的参考光谱和从属光谱辐照度。xls文件位于https://standards.iso.org/iso/9845/-1/ed-2/en/

This document provides an appropriate reference spectral irradiance distribution to be used in determining relative performance of solar thermal, photovoltaic, and other systems, components and materials where the direct or hemispherical irradiance component is desired.This document provides one reference hemispherical irradiance spectrum, one reference direct normal irradiance spectrum and 171 subordinate hemispherical tilted irradiance spectra. The reference spectral irradiance presented in this document defines an air mass 1,5 solar spectral irradiance, for use in solar applications where a reference spectral irradiance is required, for the direct normal radiation 5,8° field-of-view angle and hemispherical radiation on an equator-facing, 37° tilted plane for albedo corresponding to a light sandy soil. The reference spectral irradiance  are intended to represent ideal clear sky conditions.The reference spectra and the subordinate spectral irradiances representing different sky conditions are provided in.xls files available at https://standards.iso.org/iso/9845/-1/ed-2/en/
