The Impact of Non-Uniform Irradiance on PV Systems with Different Substring Sizes

Solar photovoltaic (PV) systems offer promise but face challenges from non-uniform irradiance, including shading and cell failures. Even one shaded cell can significantly impair or disable a larger PV module section. This study uses advanced geospatial analysis to investigate the impact of non-unifo...

Description
Summary:Solar photovoltaic (PV) systems offer promise but face challenges from non-uniform irradiance, including shading and cell failures. Even one shaded cell can significantly impair or disable a larger PV module section. This study uses advanced geospatial analysis to investigate the impact of non-uniform irradiance on residential solar photovoltaic (PV) systems. A significant increase in energy harvest potential is observed in comparing conventional PV panels with proposed Daanaa-enabled panels featuring smaller substrings and improved inter-connections. Proposed panels show up to 42.2% improvement in energy harvest capabilities, with an average of 15.3% compared to conventional PVs, emphasizing the importance of optimized solar cell interconnections.
