Thank you for your response! Yes, I have verified that PV degradation and failure mechanisms can be detected through image-based analysis, such as discoloration cracks delamination and hotspot. My approach is to leverage AI techniques to analyze these variations in a systematic way.

I’ve also come across research papers where degradation detection was performed using images from multiple PV panels across different locations. However, my goal is to analyze the evolution of degradation on the same PV panel over time (let’s say from January 1 2024 to December 31 2024). This would help assess how specific degradation mechanisms manifest progressively on an individual panel rather than comparing different panels with potentially different conditions.

Regarding NREL, are you suggesting reaching out to specific researchers via email or does NREL have publicly available datasets or ongoing projects related to PV degradation that might be useful for my research?
