Solutions to Overcome the Performance Attenuation of a Solar Panel Due to Shadowing

Maximizing the PV array's output is a significant challenge that has been overcome. Under shading conditions, output extraction becomes more laborious because there is numerous local maxima but only one global maximum. Few algorithms can track the exact global maximum in this situation, despite the fact that various maximum power point tracking (MPPT) algorithms are utilized to track global maximum. To get much efficient output in this paper cuckoo search algorithm is used for MPPT under Partial Shading Condition that operates as metaheuristic concept which continuously samples the panel voltage & current. In first stage partial shading condition (PSC) is related and in second stage cuckoo algorithm is used for tracking Global Maximum Power Point (GMPP). In third stage zeta converter is used which has good input to output Dc insulation and buck boost capability. In stage fourth the output from converter is proposed PWM control for AC applications. The proposed system is shown Matlab/Simulink and output is verified successfully.
