Cloud edge effects... WOW!

I've been seeing some pretty steady output well over the panel ratings. This is due to array tipped to 65° and snow on the ground reflecting sun. It is different than cloud edge effect. Cloud edge effect is momentary but this output remains steady all thru peak sun. I pulled over 54Kwh off 8.42Kw of array in one day. Under peak sun it was 4.54Kw off 4.24Kw panel string. Panels are not bifacial. Loads from 8 am until 5 pm were 29.662Kw and battery was charged 25.1Kw during that time. And yes, the battery Kw is accurate as reported by the smurf colored Smartshunt.

I noticed this effect last spring with snow still on the ground and panels at 65°. Works well for me. I dump excess into heating my house. SCC's are under paneled and battery was down on SOC at the beginning of the day. House is like a sauna, 78°F.
