What is your highest solar production?

I've seen a momentary peak production number of 17 kw, thru 15.2 kw capacity inverter. My best daily number in a big 10 months of operation was 65.8 kwh.

I installed 40 panels in 2016 and completed another 20 panels for Phase 2 in 2017. My system is 16.1 kW gross and 14 kW net with my enphase microinverters. When my solar system was new, I hit 107 kWh on a perfect and cool, sunny May day. After 7 years and some degradation, I just hit 92 kWh this past week on a perfect and cool, Sunny March day in Iowa.
In both cases, its just a @Q#@% (pv size measuring) contest though, right?

Tessa's Tesla
87.3 kWh in a day from a 10.15 kVA AC (11.6 kW DC) system.
Peak continuous (15 minutes) output 10.26 kW AC
Peak continuous (15 minutes) output 10.26 kW AC

I'll admit to thinking a little more about this subject....
I get my numbers from the Tesla app as my system is 100% Tesla. The production graph in the app plots a curve based on numbers updated at 5 minute intervals. The plotted number is the result of some calculation that comes up with an aggregate number based on the variations within the 5 minute period. So, catching a burst generation number requires looking at the "real time" generation number when the burst occurs, and cannot be observed after it passes. Therefore, any actual highest burst is unknown, only an observed number is available, and then as a memory rather than a record. I therefore have reduced confidence in any burst number I might report.
Looking at the best days, the best burst production I've seen, and the best production curve posted number, a few observations emerge....
1 The best plotted graph numbers I have never appear on the best production days. They appear on days with a production graph chopped up by smaller fast moving clouds, and appear as peaks imediately following a low point resulting from temporary cloud blockage. My highest yet is 13.4 kw.
2 The best burst production numbers that I've observed do seem to occur on some of the best days, but do not last long enough to obviously influence the plotted aggregate numbers.
3 So of course, the best production days are on graphs that have not been "stretched" vertically to accomodate the higher plotted numbers.
Along with the above possibly meaningless observations, I'll share that yesterday (March 24) I had the sixth best production day that I've had since going into operation on June 10 of last year, and the best day since July 5 at 57.3 kwh. My production is a little constrained both early and late in the day from living in the woods.

Not meaningless at all, all good observations! Tesla charts are 5-min energy averages that show data in units of power, so like you observed all peaks are troughs are smoothed out. This is especially relevant for bursty home loads, where peaks can be much higher than the charts make you believe. Solar generation tends to have a bit less variation because the peaks are also limited by your inverters.
The cloud effect you observed is the cloud lensing effect that leads to short bursts of high solar generation.

I have two discrete systems (7.5kw and 4kw) on three different roof planes (south, west, east). My highest peak power is ~10kw and highest daily energy production is about 85kwh.
