Abstract The conventional bypass diodes used in solar photo-voltaic panel have side-effects of forward voltage drop, reduction in efficiency and a few operational problems under partial shading condition. In this work, this bypass diode is replaced by an electromagnetic relay through an efficient alternative approach that consumes less power and offers higher efficiency under partial shading condition of solar module. This approach removes the problems like hotspot formation of the solar cell, open circuit fault under shading condition. A part of this work has been reported and published as an Indian patent. In this extended research work, the different components are designed for the partial shading condition. The hardware setup is developed, and hardware results are compared and validated with the simulated results. The proposed electromagnetic method, with no semiconductor device, works efficiently and effectively under partial shading (low irradiance) scenarios.

一种提高部分遮光下光伏面板性能的电磁策略

摘要 太阳能光伏板中使用的常规旁路二极管具有正向压降、效率降低和部分遮光条件下的一些操作问题的副作用。在这项工作中，该旁路二极管通过一种有效的替代方法被电磁继电器取代，该方法消耗更少的功率并在太阳能模块的部分遮蔽条件下提供更高的效率。这种方法消除了太阳能电池的热点形成、遮光条件下的开路故障等问题。这项工作的一部分已作为印度专利报告和出版。在这项扩展研究工作中，针对部分遮蔽条件设计了不同的组件。开发了硬件设置，并将硬件结果与模拟结果进行比较和验证。
