本文件给出了在太阳能应用中使用日射强度计的推荐做法（例如，测试太阳能光伏板、太阳能集热器或其他设备，以及太阳能系统的性能监测）。当测量阵列平面、整体水平和反射辐照度或太阳模拟器的辐射时，它适用于日射强度计的室外和室内使用。可在水平或倾斜表面上进行测量，日射强度计可为扩散计的一部分，即与遮阳装置结合以测量扩散辐射。

This document gives recommended practice for the use of pyranometers in solar energy applications (e.g. testing of solar photovoltaic panels, solar thermal collectors or other devices, and performance monitoring of solar energy systems). It is applicable for both outdoor and indoor use of pyranometers, when measuring plane of array, global horizontal and reflected irradiance, or radiation from a solar simulator. The measurement may be carried out on either a horizontal or an inclined surface, and the pyranometer may be part of a diffusometer, i.e. combined with a sun-shading device to measure diffuse radiation.
