PEMODELAN PERSAMAAN MODUL PHOTOVOLTAIC YANG MEMILIKI DIODA BYPASS PADA SAAT GANGGUAN SHADING

Abstract

S : Photovoltaic (PV) modules are devices that convert sunlight to electricity. The usages of PV modules become more popular from time to time. In a certain condition, PV modules can have multiple problems. One of many problems found in usages of PV modules is shading. Shading is a condition where sunlight is blocked by objects that makes shadow around the surface of PV modules which lead to a decreasing of productivity and efficiency in power generation. Shading issue can occurs to a single cell or group of cells in PV module which not only can cause a drastic decreasing in power generation but also can cause structure failure and fire. Equation modeling is needed to represent power, current, and voltage characteristic of PV module when shading occurs. Method that used in this research is a synthesis of several method which is detailed equation modeling of PV module and varying shading amount of a PV module using Simulink MATLAB program. The results shows that current and voltage characteristic and power and voltage characteristic are representing PV module behaviour in shading condition which can be analysed and lead to further research and development of PV devices and systems.
