标准摘要
[中文适用范围]： 本文件提供了适当的参考光谱辐照度分布，用于确定太阳热、光伏以及需要直接或半球形辐照度分量的其他系统、组件和材料的相对性能。 本文件提供了1个参考半球辐照度光谱、1个参考直接法向辐照度光谱和171个从属半球倾斜辐照度光谱。 本文件中提出的参考光谱辐照度定义了空气质量 1,5 太阳光谱辐照度，用于需要参考光谱辐照度的太阳能应用，用于直接法线辐射 5,8° 视场角和半球辐射在面向赤道的 37° 倾斜平面上，反照率对应于轻质沙土。 参考光谱辐照度旨在代表理想的晴空条件。 代表不同天空条件的参考光谱和从属光谱辐照度在 .xls 文件中提供，网址为 https://standards .iso .org/ iso/ 9845/ -1/ ed -2/ zh/ [外文原描述]： 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/
