    Effect of shading on PV panel technology
    (Institute of Electrical and Electronics Engineers Inc., 2018) Tripathi, A.K.; Murthy, C.S.N.
    Solar photovoltaic energy conversion has gained much attention nowadays. The performance of solar photovoltaic system mainly depends on the solar radiation falling on the panel surface. Shading across the panel surface is the main cause for the degradation of its performance. It was found that due to 25% shading strength in mono crystalline PV panel the reduction in short circuit current and maximum power output was respectively 40.72% and 41.40%. Similarly, the reduction in short circuit current and maximum power output was 60.86% and 61.80%, respectively for poly crystalline panel. Under the same level of shading the monocrystalline PV panel shows less reduction in its performance when compared to poly crystalline PV panel. © 2017 IEEE.

    Performance of a PV panel under different shading strengths
    (Taylor and Francis Ltd. michael.wagreich@univie.ac.at, 2019) Tripathi, A.K.; Mangalpady, M.; Murthy, C.S.N.
    Solar radiation and the surface temperature of a PV panel are the two key parameters that play an important role in the performance of the PV panel. The shading on the panel surface reduces the solar radiation falling on its surface, thus degrading the panel performance. Moreover, the effect of shading is also influenced by the panel configuration. The performance of the PV panel under different levels of shading strength and panel configuration is the main focus of this study. It was reported that, due to 50% shading of a single cell, the reduction in maximum power output was 25.71%. Similarly, the reduction in maximum power output was 70.27% with 50% shading of the panel surface. Further, in this study, the reduction in the PV panel power output was reported as 16.54% and 6.03% for the series and parallel configuration, under the same level of shading condition. © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group.
