Last evening, I went out to the extension where the solar PV control gear is siyuated and noticed that the Enphase interface was flashing indicating a single watt hour of production about every 20 seconds - this was at 21:50! No street light iminge on any of the panels and I don’t think any neighbours light were shining on any panels - any ideas please? Regards, Toodles.

I would say tolerance on the power output measurement. Chances are nothing was being generated. My inverter PV import sleeps overnight during the night-time. You can hear a relay clicking on and off at first light as it sees if any Solar PV is generated. It'll wake up if it is, else snooze for a few more minutes and try again. It varies the wake up time depending on the seasonal calendar. They are rather clever things 🙂
