But "Tesla" didn't produce ? Tesla only stored in your system?

PV panels are not from Tesla, are they?

In the end it doesn't say much. If I put a whole acre of panels in Winnipeg I might produce more than you...
I remember you had a LOT of panels. And you're far south, so higher sun angles. So total production (an extensive property...) is not a useful measure.

Not Tesla panels. 10kw array. First full year it met is design spec.
It is interesting that 25% of my production was “stored”. On track for a 9 year ROI

I've been meeting my design spec ever since the first full year 2019. Though I may be 100 kWh below (well, I don't know how it rounds, it may read 6.1 MWh this year rather than 6.2 (design spec) or 6.3).

Curious how your system will behave re:degradation. Sun exposure is higher there, so possibly more harm done w/ heat than here. (Though newer panels, possibly better, and different brand, so hard to compare.)

I don't know whether the weather has become more sunny here, but 7 years in I'm not seeing any of the expected few %-level decline in production.
Maybe the decline will accelerate a bit so that I reach the 92% at 20 years (or was it 25? I forgot)?
