Abstract: The shading of any PV panel reduces the overall performance of the panel. To overcome these shading effects, the PV panels are connected in different combinations such as series, parallel, series-parallel and total cross tied configurations. These configurations give a better performance during the partial shading. In this paper, four PV panels of 15 W are analysed for the experimental study and this work has been validated with the help of simulation in MATLAB/Simulink. The performance of the developed model has been analysed by the current-voltage and power-voltage characteristics, maximum power, short circuit current, open circuit voltage, overall electrical efficiency and the fill factor. Among the various configuration methods tested, the total cross tide (TCT) provides maximum power and efficiency as compared to the other configurations with different shading patterns.

Keywords: renewable energy; photovoltaic module; PV array configuration; partial shading; PV cell characteristics.
