Just tested my new Kyocera KC40T panel in the sun all day yesterday to see that it meets the specs as shown on it's label.
The Isc rating is 2.65amps...however, I got reading with a digital volt meter of over 3.21amps at times and sustained amps of around 2.7 to 2.8 amps..will the panel settle in to its rated 2.65Isc after a bit? My concern is that I have sized my system to use 3 of these panels in parallel going to an ASC 12/12-a charge controller.
By the way the specifications in the altE store for the KC40T need to be updated.

The current "peaks" you've observed may be the result of what some people call "Edge of Cloud" events. It is called that because momentary performance peaks have been observed as the sun emerges from a cloud. I believe that these current peaks are the result of sunlight suddenly hitting panels that have had a chance to cool down while the sun was behind the cloud. If you look at the spec-sheet for your panel, it shows that improved performance with cooler temperatures. Others may have different explanations, but this is MHO.
I have 5 (85-watt) kyocera panels in parallel, and I should see current readings of no more than 25.1 amps. I've seen peaks in excess of 29 amps last winter, but not more than 26 amps during on any recent hot summer day.
So, to answer your question, I believe that you'll continue to see those current peaks, especially in cool weather.
