Solar Panels maximum output compared to actual output

Hey all I've had a 3.5kWp solar PV installation up for about 2 weeks now. The maximum output I've seen at any one time is 2.7kW. Bearing in mind the sun is at full strength this week and I'm 99% sure that it can't get any brighter! So my question, is that normal for a solar system to have an actual output which is over 20%…

I've just compared yesterday with the day before, too.
Both Tuesday and Wednesday we had full sun right from start to finish. However, Wednesday (yesterday) performed 5% better than Tuesday presumably due to the wind cooling the panels slightly even though the air temperatures we the same on both days.
