Returning to the described problem...
A after a more detailed look at the graphs, they suggest me that the PV cell may have a thermal problem. There isn't spikes or random readings, suddenly it just starts to give lower readings. This leads me to think that when the temperature rises, some internal connection in the PV cell fails, which makes that it provides less current, than is supposed to do.
As said by PM, a new PV cell is already flying to you.
