This paper demonstrates a statistical analysis approach, which uses T-test and F-test for identifying whether the crack has significant impact on the total amount of power generated by the photovoltaic (PV) modules. Electroluminescence (EL) measurements were performed for scanning possible faults in the examined PV modules.
Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module. The length of micro-cracks can vary; some span the whole cell, whereas others appear in only small sections of a cell. Micro Cracks in Solar Panel How do micro-cracks occur?
1. Introduction Cell cracks appear in the photovoltaic (PV) panels during their transportation from the factory to the place of installation. Also, some climate proceedings such as snow loads, strong winds and hailstorms might create some major cracks on the PV modules surface , , .
To preserve solar field efficiency, the effect of cracks on the performance of solar panels is of immense importance. Hence, power loss evaluation of PV panels and approximation of the possible impact of cracks need to be measured using detailed procedures (Bekkelund, 2013).
Experimental results show the effectiveness and robustness of the proposed framework. As a future work, this study can be extended to more than one PV cell. The output efficiency of a PV panel changes drastically with an increase in number of cracked cells. This effect varied with location of the cracked cell.
The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module's production and handling are not up to the required standards. Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module.
