摘要: 光伏组件在实际工程应用中因各种异物遮挡会形成不同阴影遮挡,导致组件输出性能减弱。本文以多晶硅光伏组件为研究对象,采用实验手段探究多模式遮挡效应对实际组件输出电性能的影响。结果表明:单片电池不同遮挡比例对组件输出电压、电流、功率均有明显影响,遮挡面积越大组件功率下降百分比越大;电池遮挡片数对组件输出电压、电流、功率影响更为显著,当遮挡片数为3片时,三个时间段组件功率下降百分比均已达80%以上;不同遮挡方式对组件输出电流和功率影响较电压大,当采用双列横向遮挡方式时,功率下降百分比达95%以上;不同遮挡位置主要通过影响组件输出电流以影响输出功率,采用对角遮挡时组件功率下降百分比达到80%以上,中午时段尤为明显,接近90%。本文研究结果为多晶硅光伏组件系统应用提供数据支持。

Abstract: In practical engineering applications, different shadow occlusion may occur in photovoltaic modules caused by foreign bodies, resulting in weakened output performance of module. In this paper, the influence of multi-mode occlusion effect on the output electrical performance of modules based on polysilicon is investigated by experimental method. Results show that 1) the output voltage, current and power of module are greatly affected by different shielding ratio of a single battery, and the larger the shielding area, the greater the power decrease percentage of module; 2) the number of battery occluding pieces shows more significant influence on the output voltage, current and power of module: when the number of occluding pieces is 3, the power decrease percentage of module exceeds 80% under the three time segments; 3) different shielding modes have greater influence on the output current and out power than voltage of module, and the power decrease percentage can exceed 95% when double-row transverse occlusion is used; and 4) different occlusion positions affect the output power mainly by affecting the output current of module. When diagonal occlusion is used, the power decrease percentage of module exceeds 80%, especially in the noon period when the percentage can reach 90%. The influence of different tilt angles on the output power of module with the same occlusion position is relatively weak, while that of occlusion on the output power of module is huge. The results of this study provide data support for the application of polysilicon photovoltaic module system.
