What spectral range does a PV module have?

Common and traditional PV modules have a low average reflectance between 500 nm and 1000 nm (Czirjak, 2017), which is used to absorb more solar energy in this spectral range. For example, monocrystalline PV cells are blackish, and polycrystalline PV cells are dark bluish.

What are spectral features of PV modules?

As the market share of silicon solar cells currently exceeds 90% (Silvestre et al., 2018), this feature can be treated as another main spectral feature of PV modules. The index of average reflectance in the VNIR (aVNIR) (see Fig. 5) targets strong spectral absorption features in the VNIR region of PV materials.

What are the different types of PV based on spectra?

Future studies could explore to distinguish different types of PV based on their unique spectra such as the mono- and polycrystalline silicon, cadmium telluride (CdTe), copper indium selenium (CIS), and copper indium gallium selenide (CIGS) modules (Visa et al., 2016, Burduhos et al., 2018). 6. Conclusion

How to detect PV modules using imaging spectroscopy?

Therefore, PV modules detection using imaging spectroscopy data should focus on the physical characteristics and the spectral uniqueness of PV modules. PV modules commonly consist of several layers, including fully transparent glass covers for protection, highly transparent EVA films, and the core PV cell.

Can imaging spectroscopy data detect PV material as pure pixels?

Moreover, the spatial resolution of the imaging spectroscopy data should be sufficient to detect PV material as pure pixels. This study aims to create greater awareness of the potential importance of imaging spectroscopy data for PV identification.

What is physics based solar PV?

This physics-based approach is robust, transferable and operational. Over the past decades, solar panels have been widely used to harvest solar energy owing to the decreased cost of silicon-based photovoltaic (PV) modules, and therefore it is essential to remotely map and monitor the presence of solar PV modules.
