Modeling and simulation of grid connected Photovoltaic System for Malaysian climate using Matlab/Simulink

The impact of solar irradiance, ambient temperature and clearness index on the outdoor performance of poly-crystalline (poly-Si) PV modules is considered. This paper highlights the effect on the energy output by changing the clearness index for the Building Integrated Photovoltaic System (BIPV) in Malaysia. Simulation was implemented using MATLAB/SIMULINK and results are compared with the actual monitored data. A case study was presented for a 45.36 kWh system using poly-crystalline module and results show that the energy output differs from 7.23% to 8.52% with clearness index of 0.55 and hence clearness index also influenced the energy output besides solar irradiance and temperature.
