Partial shading is the commonly encountered scenario of building roof-top based PV arrays that mainly occur due to the shadow of the neighbouring buildings and clouds resulting in unexpected losses and deteriorated system performance. The arrays are connected in various configurations to enhance the system performance during shading. In this paper, various conventional and hybrid interconnection configurations based on series-parallel (SP), bridge-linked (BL), and total cross tied (TCT) topologies of the roof-top PV arrays are examined under various partial shading scenarios caused by the neighbouring building and clouds. The investigation is done for a <inline-formula> <tex-math notation="LaTeX">$9\times 9$ </tex-math></inline-formula> roof-top array in MATLAB/Simulink environment considering various comparison parameters. It has been found that during 1.23&#x0025;, 7.40&#x0025;, 11.11&#x0025;, 17.75&#x0025;, 18.51&#x0025;&#x0025;, 22.22&#x0025;, and 24.69&#x0025; of total array shading, SP generated the maximum power whereas, during 30.86&#x0025;, 61.72&#x0025; shading, TCT has the generated only a slightly higher power as compared to SP. Hence, the study concludes that the configurations have a puny effect on the power generation of the arrays during uneven shading patterns caused by buildings and clouds.
