摘要: Modules of solar photovoltaic (PV) array are normally connected in series-parallel pattern. This may causes dependence between PV modules. dependency produces bad impacts at partial shading condition. To reduce these effects optimum configuration should be designed. procedure needs to find a way calculate the dependency. Furthermore, power reduction due shadow is not directly proportional darkness. At condition, changes irradiation intensity would influence total maximum point (MPP), as long this shaded was lower or larger doorsill value. Dependency factor and effect both could analyzed by binary coding method which aim paper.
