When solar cells are inspected from the front, an IR camera sees the heat distribution on the glass surface. Only indirectly can it see the heat distribution in the underlying cells. Thus, the temperature discrepancies that can be measured on the solar panel''s glass surface are small. In order for these differences to be visible, the IR camera requires a …

Because solar cells convert light to electricity, radiometry is a very important facet of PV metrology. Radiometric measurements have the potential to introduce large errors in any given PV performance measurement because radiometric instrumentation and detectors can have total errors of up to 5% even with careful calibration [11], [12].
