On my graphs of the energy generated from the Kaco Inverter company, I see a new dip that is there everyday at 1:15p.m till 2:15 p.m., for a week now. I will check for any new shading that is occurring at this time. I checked the other day and did not see anything in the afternoon, but I haven’t checked exactly at 1:30 p.m. I will let you know. Here are the graphs for the last few days.
