Comparative Analysis of Different Shading Patterns in Case of Total Cross Tied Connection for Solar PV Panels

Abstract

In the present time the overuse of fossil fuels for energy production not only causes the extinction of these fuels but also significantly worsens the environment. The best alternative for achieving a better environment is to include renewable energy-based generation. Solar power is the most efficient option on the list and produces the most power. The sun insolation, temperature, angle of inclination, and partial shade conditions all affect how much power the photovoltaic (PV) panel can produce. The common causes of shading of PV arrays are passing cloud, buildings, trees, poles communication towers, chimneys, adjacent panels, leaves, snow, bird droppings etc. Partially shaded solar panel provides P-V curve which has multiple peaks. However, in order to get the most influence, it is crucial to comprehend and anticipate them. This paper takes into consideration different shading patterns for TCT connection under the parameters like Fill Factor, Power Loss, percentage power output. Power against voltage and current against voltage characteristics are plotted for various shading conditions in case of TCT connection and the output is compared for respective shading patterns. It was found that the diagonal shading pattern produces the maximum output. The results obtained by simulating the TCT connection for different shading condition is compared conclusion is made as to which shading pattern yields maximum output with minimum losses. The comparison tells that crosswise shading pattern gives maximum output.
