Partial Shading Effect on Power Generation of BIPV System in Bangladesh

Abstract

The research tries to observe the power difference for the PV module in the case of the partial and void of partial shading in Bangladesh. For analysis of the partial shading effect on the PV module it is necessary to establish an experiment set up for the PV module. To investigate the power output from PV module the partial shading effect has been generated using the paper coverage. The experimental result shows that the photovoltaic module can generate up to 41% more power output in the case of the void of the shading effect rather than in the shading effect. Around 50% portion of the PV module has been shaded for making partial shading effect. The other important factors influencing the output power of the PV module are solar irradiance, cell temperature; ideality factor. To get the maximum output it is essential to avoid shading effect which will help to generate more power. In this paper, MATLAB simulation of PV module has been done showing the partial shading effect under consideration of various factors like series resistance, ideality factor, temperature. Partial shading effect has been created by varying the level of solar radiation.  An experiment has been carried out to see the overall performance of PV module under shading effect at a fixed tilt angle.
