Experimental system design for online characterization and performance analysis of PV module under distinguish environmental conditions

Abstract

This paper is a novel attempt to evaluate the performance of photovoltaic (PV) modules using current-voltage (I-V) and power-voltage (P-V) characteristics. Numerous significant performance parameters, such as open-circuit voltage, shortcircuit current, maximum power point (MPP), fill factor (FF) and efficiency, are evaluated under various environmental conditions during the investigation. In order to capture online solar electrical parameters, a low-budget test rig is developed using Arduino-assisted supporting components and interfaced with the MATLAB Graphical User Interface (GUI) environment to demonstrate experimental I-V and P-V characteristics. The performance assessment is conducted for three naturally available dust samples categorized using types and weights. In addition, reflectors are often used to boost the efficiency of clean and dusty modules for comprehensive comparison. The present study is useful for three aspects: designing a low-cost PV analyser; choosing the location of the solar power plant; and enhancing the efficiency of the current solar plant.

Chess Game Rook‐Icon Movement‐Based Photovoltaic Array Reconfiguration for Higher Shade Dispersion and Improved Global Power Peaks Under Partial Shading Conditions: An Experimental Study

“…Step-I: Primary Matrix Development: Based on the rules set up, this proposed primary matrix comprises nine nonrepeating integer elements (1)(2)(3)(4)(5)(6)(7)(8)(9), where the sum of the rows, columns, and diagonals is equal. Basic rules for developing the 3 Â 3 size matric are expressed in Equation ( 12) and ( 13) as,…”

“…The direct benefit of the reconfiguration using game puzzle-based methodologies is to achieve higher shade dispersion on entire PV array systems. [4,5] There are many ways to change the electrical configuration of a PV array using the physical reallocation of PV modules and static electrical connection. Several game puzzle methodologies are explained in the literature, such as Su-Do-Ku (SDK), magic square (MS), Latin square (LS), symmetric matrix (SM), etc., to reduce the shadowing impacts on PV performance.…”

“…Under the shading scenario, multiple global and local maxima power points exist on the P-V curves. Herein, the chess game rules for the "Rook" icon are followed to attain the optimal placement of integer numbers (1)(2)(3)(4)(5)(6)(7)(8)(9) in the 9 Â 9 size game puzzle matrix. The integer number-based game puzzles such as Su-Do-Ku, symmetric matrix, and proposed Rook's movementgame theory (RMGT) to rearrange the PV modules in arrays are investigated and compared with the standard arrangements such as series-parallel, total-cross-tied during PSCs.…”
