Forensic appraisal of photovoltaic panel quality
This paper presents a review of imaging technologies and methods for analysis and characterization of faults in photovoltaic (PV) modules. One critical layer is the backsheet [1], which protects the internal components from environmental contamination. Experimental results indicate that. . While traditional visual and infrared (IR) inspections are still a common practice, a more advanced diagnostic method is emerging as an invaluable tool for solar operators: electroluminescence (EL) testing. According to kWh Analytics, a leading solar risk assessment and mitigation expert, project underperformance is a genuine and growing concern.
