太阳电池组件户外性能测试

为了研究在户外工作条件下太阳电池组件的实际工作性能,在一天过程中的太阳电池组件V-I特性、组件温度、环境温度和太阳辐照度被测试。结果发现:影响太阳电池最大输出功率的主要因素是太阳辐照度;工作温度对电池组件的效率影响较大,同时高的工作温度还会使最大功率电压降低很多;太阳光谱对太阳电池组件的输出性能也有一定的影响,当辐照主要以散射为主时,太阳电池组件有更高的转化效率。

Characterization of PV modules under actual operating conditions

To evaluate PV module performance under actual illumination and temperature operating conditions over the course of a day,V-I characteristics of PV module,operating temperature,ambient temperature and solar radiation were measured.Results demonstrate that solar intensity greatly affects the maximum power output;the high operating temperature decreases the efficiency of PV module,and it also much lowers the maximum power voltage;solar radiation spectrum also has a little influence on output performance of PV module,while solar intensity is mostly diffuse skylight,the PV module has a higher efficiency.
