Abstract
The PV panels are interconnected in SP configuration in order to achieve a higher voltage. The SP configuration of PV string may undergo both objective and subjective partial shading situations which reduces the generated maximum output power. Thus, the research work carried out the analysis of PV array rated 1500 W for different shading patterns like row-wise and column-wise partial shading. The behavior of solar array is also studied under different irradiation levels and different degrees of shading. The behavior of PV string characteristics for with and without bypass diode under different shading scenarios has also been analyzed using MATLAB/SIMULINK. The performance parameter of a solar array such as power loss, fill factor and a maximum power of the PV string is evaluated and compared. From the analysis, it is inferred that the generated output power gets deteriorated for low irradiation level and low degree of shading. The results are verified.
