光伏组件发电量户外实证研究

Outdoor power generation of photovoltaic modules: an empirical study

对于地面用晶体硅和薄膜光伏组件,传统的性能表征主要分为环境、力学、电性能、安全等几个方面。其中电性能表征局限于特定温度和辐照度条件,对于光伏组件户外实际应用过程,本文介绍了光伏组件发电量户外实证测试的三种方法:MPP跟踪的光伏组件发电量测试,基于光伏电流-电压特性测量的光伏组件发电量测试,以及多因子影响光伏组件发电量的评估方法。

For ground-based crystalline silicon and thin film photovoltaic modules, traditional performance characterization can be divided into environmental, mechanical, electrical, safety and other aspects. Electrical performance characterization is limited to specific temperature and irradiance conditions. For the outdoor practical application of photovoltaic modules, this paper introduces three outdoor empirical testing methods of photovoltaic modules： MPP tracking photovoltaic module power generation measurement, photovoltaic module power generation measurement based on photovoltaic current-voltage characteristics measurement, and Multi factor evaluation method of PV module power generation.
