Solar Photovoltaic systems are used for electrical power generation, and they provide an alternative source to non-renewable energy sources like coal, oil, natural gas and nuclear energy. Photovoltaic arrays used in PV systems may be subjected to partial shading conditions, thereby affecting power generation because of higher power mismatch losses. Due to an uneven distribution of irradiation condition, some of the bypass diodes turned on and affect the power generation in a photovoltaic array. The mismatch losses are due to the output from PV panels subjected to different irradiations because of non-uniform partial shading conditions. The power loss can be reduced by uniformly distributing the partially shaded condition over the entire PV array. In this work different shaped 4 × 4 array configuration is proposed to overcome the effect of partial shading condition, thereby providing lower mismatch losses. Simulations under different partial shading conditions are carried out using MATLAB Simulink, and the experimental setupis carried out for the proposed array configuration for 4 × 4 PV array and the results are discussed.
太阳能光伏系统用于发电，它们为煤炭、石油、天然气和核能等不可再生能源提供了替代能源。光伏系统中使用的光伏阵列可能会受到部分遮挡条件的影响，从而由于较高的功率失配损耗而影响发电。由于辐照条件分布不均，一些旁路二极管导通并影响光伏阵列中的发电。失配损耗是由于光伏面板在不均匀的部分遮挡条件下受到不同辐照而产生的输出。通过在整个光伏阵列上均匀分布部分遮挡条件，可以降低功率损耗。在这项工作中，提出了不同形状的4×4阵列配置，以克服部分遮挡条件的影响，从而提供较低的失配损耗。使用MATLAB Simulink在不同的部分遮挡条件下进行了仿真，并针对所提出的4×4光伏阵列的阵列配置进行了实验设置，并对结果进行了讨论。
