Comparative Study of Different Configuration Techniques to Address the Outcome of Partial Shading Conditions on Solar Photovoltaic System

Abstract

As per energy and power productivity of a solar photovoltaic (SPV) system is evaluated, Partial Shading Conditions (PSC) play a significant role. Under PSC, the panels of a SPV modules receive various levels of solar irradiance, as a result power generation of a SPV system diminishes, and these losses in SPV panels may be decrease by changing the configuration of the panels in array/module. The panels may be configure in many different configuration such as Series(S), Parallel (P), Series Parallel (SP), Total Cross Tied (TCT), Bridge Linked (BL), and Honeycomb (HC) to improve the output energy and power efficiency. This work is aimed to present all the configuration that already been presented in literature and result of PSC on SPV systems are referenced and analyzed. There are four configuration 4×4 array of solar photovoltaic panels to be discussed in this paper. Four configuration are Series parallel (SP), total cross tied (TCT), bridge linked (BL), and honey comb (HC). Four simulated models were performed to decide to effect of shadow with 10 shading patterns. The simulated results shows as a power against voltage (PV) curves of 4×4 array of SPV under PSC for above mentioned configuration. The PV curve of the proposed configuration is enhanced the power efficiency and the minute and exact finding of global maximum peak is simpler. The test of the simulated modules and its theoretical results ensure the effective implementation of this techniques in hardware setup also. It is confront that this work will be a reference of useful and important information for researchers in Solar panel area. The work presented in this papers envisages to be a source.
