What could be the cause of the power drop?
HI! I had a 6KWp solar installation on my roof for about three years now, and I often notice it's production is quite inconsistent.
This is yesterday compared to tomorrow: Yesterday was a fairly sunny day with the occasional cloud, and I reached a max of ~3.5KW of peak output. Today was the sunniest day in weeks, but with the lowest peak output yet at ~2.5KW.
I have been trying to find an explanation for this for a good while without success. Panels are on the roof with absolutely zero shading, house is taller than all trees around it, and visibility is just slightly lower today (25km vs 20). So... What could it be?
yellow line is solar production, btw
