I thought it would be useful to highlight the detrimental effect even minor shading has on a panel and/or string.
I got my script working again that pulls data from my micro inverter working so I can monitor the output from each panel. I had noticed that one of my panels was producing a reduced output (19%)
I investigated when I got home and found the following flower covering less than a cell on one panel!
TBH I was gob-smacked on the effect of this minor shading and how much it affects the output of the panel!
The moral of the story is to not underestimate any shading on PV panels…
