6 FAQs about [Non-destructive disassembly method of photovoltaic panels]

Can hyperspectral imaging be used to identify a defect in PV cells?

However, the integrity of solar photovoltaic (PV) cells can degrade over time, necessitating non-destructive testing and evaluation (NDT-NDE) for quality control during production and in-service inspection. Hyperspectral (HS) imaging has emerged as a promising technique for defect identification in PV cells based on their spectral signatures.

Can a quick and non-contact approach be used to diagnose PV panels?

Overall, our proposed approach provides a quick and non-contact method for recognizing and diagnosing PV panels, ultimately leading to increased energy production and reduced maintenance costs.

Can thermal imaging detect a non-contact static diagnosis for PV cells?

Thermal imaging would not be able to identify temperature variations that could be indicative of flaws without electricity being connected to the panel. We assessed that by applying this thermal imaging technique to study the feasibility of getting a non-contact static diagnosis for PV cells using another approach.

Is hyperspectral imaging effective for nondestructive testing and evaluation of PV cells?

Based on the findings and analysis presented in this study, our novel methodology demonstrates the effectiveness of our proposed hyperspectral (HS) imaging approach combined with K-means clustering (K-mc) for nondestructive testing and evaluation (NDT-NDE) of solar photovoltaic (PV) cells.

Can a thermal imager differentiate between working and Unworking PV cells?

We tested the working and unworking PV cells using a thermal imager (Therm-App LWIR range: 8–12 µm, optical lens with f = 19 mm) after lightning the PV samples with an IR lamp. This approach couldn’t differentiate between the working and the defected PV cells, as done with our instant non-contact HS imaging approach.

Can I use NDT-NDE on externally mounted PV panels?

For NDT-NDE on externally mounted PV panels, our image clustering method may be used with a standard camera and a filter that only operates at 450 nm in wavelength.
