摘要

从历史上看，两个时间依赖因素使光伏组件和阵列性能的表征复杂化;即太阳光谱在一天中的变化，以及组件中的光学效应随太阳入射角的变化。本文介绍了直接测量这两个因素影响的简单方法。提供了商业模块的测量结果，以及典型的太阳辐照度传感器(热辐射计)。从测量中获得的经验关系可用于改进系统设计、安装后性能验证和运行期间性能诊断监测的方法。

Measuring solar spectral and angle-of-incidence effects on photovoltaic modules and solar irradiance sensors

Historically, two time-of-day dependent factors have complicated the characterization of photovoltaic module and array performance; namely, changes in the solar spectrum over the day and optical effects in the module that vary with the solar angle-of-incidence. This paper describes straightforward methods for directly measuring the effects of these two factors. Measured results for commercial modules, as well as for typical solar irradiance sensors (pyranometers) are provided. The empirical relationships obtained from the measurements can be used to improve the methods used for system design, verification of performance after installation, and diagnostic monitoring of performance during operation.
