The Impact of Partial Shading on the Photovoltaic Outcomes

Photovoltaic cells operate outdoors subjected to various climatic conditions such as solar radiation, temperature, dust and shade. The partial shadow resulted from clouds, dust, buildings and trees adjacent to the cell has a negative impact on the productivity of these cells. This paper examines the low photovoltaic performance caused by partial misrepresentation of solar panels. Partial shading leads to reduced cell productivity from electricity. The experiments were performed using artificial shading and the voltage and current of the cell were measured in each case. The results of the study showed that there is a difference in the generated voltage of the photovoltaic cell and the resulting energy depending on the type of shade and its relation to the area of the solar panel. The results showed that the effect of shadow on the group of cells connected respectively, parallel, and the mixture of the two cases completely depends on time and temperature.
