Developing energy-efficient photovoltaic systems is a fundamental challenge faced by research engineers. One of the most prominent elements contributing to the reduction in output power owing to mismatching power loss is a partial shading that shades the PV modules. These losses are determined by the PV system structure, PV array layout, shading patterns, physical placement of shaded modules, and tilt angle position at which the PV module is placed. The performance of six \(7\times 7\) PV array configurations namely Series, Parallel, Series–Parallel, Bridge-Linked, Honey-Comb, and Total-Cross-Tied are evaluated to study the effect of random, diagonal, corner, and center shading patterns. The PV array is modeled, simulated, and evaluated based on open-circuit voltage, short-circuit current, global peak power, voltage, and current. Furthermore, the efficiency and Fill Factor of each configuration are calculated for advanced analysis.

摘要

Developing energy-efficient photovoltaic systems is a fundamental challenge faced by research engineers. One of the most prominent elements contributing to the reduction in output power owing to mismatching power loss is a partial shading that shades the PV modules. These losses are determined by the PV system structure, PV array layout, shading patterns, physical placement of shaded modules, and tilt angle position at which the PV module is placed. The performance of six \(7\times 7\) PV array configurations namely Series, Parallel, Series–Parallel, Bridge-Linked, Honey-Comb, and Total-Cross-Tied are evaluated to study the effect of random, diagonal, corner, and center shading patterns. The PV array is modeled, simulated, and evaluated based on open-circuit voltage, short-circuit current, global peak power, voltage, and current. Furthermore, the efficiency and Fill Factor of each configuration are calculated for advanced analysis. KYOCERA-KC200GT PV module-based \(7\times 7\) Photovoltaic array configurations are simulated using MATLAB/Simulink software tool.
