Our system is just over a year old, so price will be irrelevant, but production wise...:
23x Maxeon 425w panels with Enphase IQ7 microinvertors
Lifetime production (Mid July '23 till today, so about 13 months) 12.1MWh produced, 7.1MWh Imported, 6.2MWh exported. (We don't appear to have been capped to 5kWh per day... yet)
Best producing day in summer was 7 Jan this year - 70.1 kWh
Worst was June 14th this year - 2.9kWh produced (its was a really crappy wet day)
I am in Palmerston North, my roof is NE facing, and my word there is a lot of pollen about that's covering my panels!!
