Photovoltaic Data Acquisition (PVDAQ) Public Datasets

The NREL PVDAQ is a large-scale time-series database containing system metadata and performance data from a variety of experimental PV sites and commercial public PV sites. The datasets are used to perform on-going performance and degradation analysis. Some of the sets can exhibit common elements that effect PV performance (e.g. soiling). The dataset consists of a series of files devoted to each of the systems and an associated set of metadata information that explains details about the system hardware and the site geo-location. Some system datasets also include environmental sensors that cover irradiance, temperatures, wind speeds, and precipitation at the site.NREL PVDAQ 是一个包含多种实验性光伏站点和商业公共光伏站点系统元数据和性能数据的大规模时间序列数据库。该数据集被用于进行持续的性能和退化分析。其中一些数据集可能展现出影响光伏性能的共通因素（例如污垢）。该数据库由一系列针对各个系统的文件组成，并附带一组解释系统硬件及场地地理定位详细信息的元数据。部分系统数据集还包括覆盖场地辐照度、温度、风速和降水的环境传感器数据。
