Development of PV module outdoor test platform

在传统工作模式电子负载的基础上提出的一种户外光伏组件测试平台,以自动切换工作模式的可编程电子负载为核心,实现了对光伏组件IV特性曲线更加精确而完整地测量。它可根据用户设定,使光伏组件在户外环境下,长期保持设定工作状态,并实时监测其输出特性。大量存储的IV特性曲线及环境参数数据,有助于分析光伏组件户外实际工作性能。光伏系统设计人员通过对比不同类型组件户外特性,针对特定工作环境选择适合的组件。平台同时也为光伏组件生产商提供了评估产品的可靠依据。

Based on conventional electronic load （E-load） ,the proposed photovoltaic （PV） module outdoor test platform can measure IV curves more accuracy and integral by centering on the programmable E-load which can automatically shift operation mode. PV modules are kept on working at the status depending on user＇s setting under outdoor condition chronically,and the real-time output characteristics are monitored. Based on the stored data of IV curves and ambient parameters,real outdoor performance of PV modules can be analyzed effectively. Designers of PV system can select specific PV modules to apply for particular environment by comparing the outdoor performance of different types of PV modules. And the data provide credible evidence for evaluating products of module manufacturers.
