Different Techniques to Mitigate Partial Shading in Photovoltaic Panels

The effect of partial shading in photovoltaic (PV) panels is one the biggest problems regarding power losses PV systems. When irradiance pattern throughout a panel inequal, some cells with possibility higher production will produce less and start to deteriorate. objective this research work present, test discuss different techniques help mitigate panels, observing commenting advantages disadvantages for technologies under operating conditions. motivation contribute research, simulation, experimental work. Several state-of-the-artsolutions problem be presented: topologies interconnection panels; system architectures, also introducing new solution hypotheses, such as cell interconnections topologies. Alongside, benefits limitations discussed. To obtain actual results, simulation was conducted by creating MATLAB/Simulink models each technique tested, all centered around 1M5P model. several tested take into account patterns sizes shading, technologies, values source irradiation, array sizes. results discussed validated tests.
