Abstract:With the global increase in the deployment of photovoltaic (PV) modules in recent years, the need to explore and understand their reported failure mechanisms has become crucial. Despite PV modules being considered reliable devices, failures and extreme degradations often occur.
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.
The hotspot failure mechanism is considered the most severe failure and leads to catastrophic consequences. It deteriorates all PV module components if undetected, and a PV module affected by an elevated level of hotspots cannot reverse the degradation and often requires replacement.
For instance, the National Renewable Energy Laboratory (NREL) developed accelerated stress tests to examine degradation rates, validating the superior quality and long-term reliability of PV modules . However, despite these measures, there are still reports of abnormal degradation rates in PV modules due to a variety of failures.
The causes of thermal spots effect can be divided into many factors, including internal defects of the PV cell, external occlusion, surface glass panel damage, series connection failure,
