Non-homogeneous irradiation patterns and temperature levels immensely affect the performance of solar photovoltaic *** shading conditions on solar arrays reduce the peak power and *** paper provides a new remedy called a novel Ramanujan reconfiguration(NRR)to eliminate this physical shading problem in solar photovoltaic *** is a static-based reconfigured technique that is built using a three-diode model with the help of the MATLAB®/Simulink®*** special feature of the proposed NRR technique is that when shade occurs on the solar modules,it gets realigned in a particular row,column,diagonal,corner,centre and middle peripheral *** helps over a wide range of shade dispersion on the solar *** novel topology is tested against the conventional total cross-tied(TCT)model and recently introduced advanced reconfigured models,namely odd–even topology(OET)and Kendoku topology(KDT).The results are tested under certain shading *** proposed NRR technique increases the peak power by 4.45,2.15 and 2.17 W under the first shading condition regarding TCT,OET and *** efficiency is improved by 0.51–2.18%under the third shading condition compared with other considered models in this *** addition,NRR leads to smooth output curves under the second,third and fourth shading conditions,effectively mitigating the local power *** experimental results show the proposed enhanced performance of the novel model against the other *** Abstract Remedy for physical problem correlated with solar photovoltaics Comparison with traditional and recent solar models Conclusion:NRR has effectively handled the problem related with solar *** has improved the efficiency up to 31.44%under ***,smooth output curves under S2-S4 shows its effectiveness in mitigating the local power *** power gain at 3.94%under S4 is achieved by novel ***-time verification proves the supremacy of novel proposed model over o
