“…Hot spots or glass shield could crack due to the excessive heat generated. Over the years, many methods to minimize the effects of power shading have been proposed to optimize the power extracted from the system under partially shaded conditions (Sridhar et al , 2016b). The conventional technique to minimize partial shading effect is to connect bypass diodes in antiparallel to the PV array.…”

Purpose The aim of this research study is to mitigate shading impact on solar photovoltaic array. Photovoltaic (PV) array when getting shaded not only results in appreciable power loss but also exhibits multiple power peaks. Due to these multiple power peaks, the maximum power point tracking (MPPT) controllers’ performance will be affected, as most of the times it ends up in tracking the local maximum power peak and not the global power peak. Design/methodology/approach The PV panels in an PV array when getting shaded even partially would result in huge power loss. The pattern of shading also plays a crucial role, as it renders a cascaded impact on the overall power output because the cells/panels are connected in series and are parallel. Therefore, during shading, intelligent schemes are needed to appropriately connect and discard the unhealthy and healthy panels in right place with right combination. This research proposes one such scheme to mitigate the shading impact. Findings To mitigate the shading impact and also to have a smooth power-voltage (P-V) curve, a new series inducing switching scheme is introduced. The proposed scheme not only mitigates the shading impact and enhances the output power but also smoothens the P-V curve that facilitates the MPPTs to track the P-V appropriately. Originality/value The research findings are inventive in nature and not copied work. The reference works and the inspirations have been duly cited and credited.
