【摘要】：结合实际生产特点,将太阳电池组件分为3个区域,通过改变连接方式以实现串联或串并联结构,构建太阳电池组件测试系统。通过数值模拟和试验验证,分析这两种拓扑结构在不同光照阴影下的最大输出功率特点。实测结果表明,在正常情况下,串联和串并联结构最大输出功率基本相同;当某区域有一片被遮挡时,串并联结构比串联结构大9.4%;当某两个区域中各有一片被遮挡时,串并联结构比串联结构大49.1%,当3个区域均有一片电池片被遮挡时,串并联结构比串联结构小5%。研究结果表明,在有部分光照阴影时,串并联结构比串联结构有更大的功率输出。
[Abstract]:According to the characteristics of actual production, the solar cell module is divided into three regions, and the testing system of solar cell module is constructed by changing the connection mode to realize series-parallel structure or series-parallel structure. The characteristics of the maximum output power of these two topologies under different illumination shadows are analyzed by numerical simulation and experimental verification. The measured results show that under normal conditions, the maximum output power of series-parallel and series-parallel structures is basically the same; when there is one block in a certain area, the series-parallel structure is 9.4g larger than the series-connected structure; when one piece of each of the two regions is occluded, the maximum output power of the series-parallel structure is basically the same. The series-parallel structure is 49.1 larger than the series-connected structure. When a battery chip is occluded in all three regions, the series-parallel structure is 5 times smaller than the series-connected structure. The results show that the series-parallel structure has more power output than the series-parallel structure when there are partial illumination shadows.
