This paper presents a defect analysis and performance evaluation of photovoltaic (PV) modules using quantitative electroluminescence imaging (EL). The study analyzed three common PV technologies: thin-film, monocrystalline silicon, and polycrystalline silicon.
They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
The primary objectives of these studies were to identify solar PV systems' failure modes. The severity rating (SR), occurrence rating (OR), and detection rating (DR) tables were also developed using the published literature. There are no specific severity, occur- performance. Therefore, it is necessary to develop an FMEA methodology to analyze solar
In this period, there was a much stronger prevalence of defective interconnections in the module, and failures due to PV module glass breakage, burn marks on cells (10%), and encapsulant failure (9%) while failures due to junction-boxes and cables remained high.
