I have had poor PV mid-day performance before due to clouds/rain etc, but today has eclipsed them all.

I pride myself in diagnostic skills and NOT knowing everything. I do know how to ask the right questions of those who should know the answers. I can do this politely.


Did the eclipse bring down your production ?!    :)

Down in Baja we had a partial eclipse. The decreased insolation was visible. Kind of like when smoke from a fire obscures the sun. I have a 2100 watt array and would usually be getting about 900 watts at that time of day. I looked at my controller and was getting just over 250 watts.
