In the presented paper, we introduce an approach to rate the performance of modules under specific real weather conditions, since solar modules are rated according to standard test conditions which do not give evidence of the performance under real outdoor conditions. Therefore, we categorize the daily weather at a photovoltaic test site into 7 different climatic‐day classifications and multiple cloud scenarios. Two different approaches to evaluate the cloud conditions were investigated. Furthermore, we use the developed approach to rate the performance of 8 different commercially available photovoltaic modules that have been installed and measured in Germany. The evaluation shows that module properties (eg, temperature coefficient, spectral response, and mechanical construction) have a major influence on the performance of photovoltaic modules under different weather conditions.

在特定的实际天气条件下，对各种光伏组件技术进行技术特定的产量分析

在本文中，我们介绍了一种在特定的实际天气条件下对模块性能进行评估的方法，因为太阳能模块是根据标准测试条件进行评估的，而标准测试条件并未给出在室外实际条件下的性能证据。因此，我们将光伏测试站点的每日天气分为7种不同的气候日分类和多种云方案。研究了两种不同的评估云状况的方法。此外，我们使用开发的方法对在德国已安装和测量的8种不同的商用光伏模块的性能进行评估。评估表明，模块属性（例如，温度系数，光谱响应，
