100w panels
I bought a Renogy kit with the hard panels (I.e. not the thin flexible panels) and mounted 3 100w panels on my van, for 300w. Anyways, in really strong direct sunlight, I have noticed the app says ...

I will agree that high altitude and/or a breeze is a benefit. First you may get solar radiation in w/sq meter above the standard reference due to the altitude. Next any breeze helps keep temperatures down. And usually high altitude= lower temperatures.
So, while I've never seen output> rated, I will change my opinion and say it is possible. not likely to occur very often, but is possible.
Also years ago, like when I bought my panels there were rated under ideal conditions. Solar engery 1000W/sq meter, cell temp 77F, 500ft altitude.
Since then the NOCT rating has been used as well which is more realistic. (Normal operating conditions and temperature) It assumes 800W/sq meter, 500ft altitude and 68F AIR temperature and a 2mph wind. Note the use of AIR temperature NOT cell temperature.
so using NOCT I can see panels oeak reading exceeding the rating on a nice sunny cool day with a nice breeze especially at high altitude as long as they are aimed within reason. I wouldn't expect that reading to last for very much of the day.
