Solar and power wall 3 quote.

Total power in the screenshot is 0.05 (0.06) MW (60 kW), not 500-600 kW?

I understand that 100 homes times 5 kW is 0.5 MW, but their data indicate that other homes maybe are giving less power than you are doing?

Got it. Top number is power my battery is being delivered. 5kw

If all 100 units were discharging at 5kw that’s the .5 Mw.

Bottom number must be the net delivery of the fleet to the grid I I was still sending to grid at 3.5 kw and it read zero.

It was a sunny solstice. 24.9 kWh. I’m averaging 20 kWh/day so far for December. I’m using 16 kWh from the grid each day on average. I think I will use up all my bill credits this month.

The advantage of not being in the cloudy NorthEast.

Or simply be farther south and having a better panel orientation: yesterday I had a clear sky day. 9.0 kWh for a 7.2 kW system that is E/W facing.

Or cloudier Pac NW at a higher latitude.

December production is in! I averaged 19.7 kWh per day. 611 kWh for the month. Bill cycle runs Nov 24th - Dec 23rd ended with a 22$ credit. Days are getting longer! Best day in January was the 5th with 26.8 kWh. Getting actual use data I think I’m going to be charging at home more to spend down the bill credits.

Ah, to have any sunny days during winter would be great - even partial sun would be nice. You generated 4.5x more than I made for the month. I made 137kwh for December and so far this month I'm at 69kwh. Snow days didn't help, neither does my flatter roof, but it is mostly the dark days from heavy overcast. I can't even use my portable panels to charge up my power stations - and those I can angle as needed plus some of them are bifacial so would pick up extra from the reflection off the snow - if there was actually sun.

217 kWh in December here. 16 more than in 2023.

THe good news is that my total power for the year has been very stable. 2019: 6.3 MWh, 2020: 6.3 MWh, 2021: .6.1 MWh, .. 6.2 MWh, .. 6.2 MWh, and now in 2024 6.3 MWh again.
I though in 2021 that the decline in performance of the panels had become noticeable. But I guess it's the weather...
I was happy to see the initial 6.3 MWh again, suggesting that the weather variability so far is larger than the slow panel performance decline.

These are LG panels

I've only had my panels a couple of years, but the monthly difference between the years can be staggering percentage wise. Decembers, in order, I have had 165, 180 and this year at 137 (difference of 24% this year against last year). Januarys seem to be stable at 116.7 & 116.2 so it will be interesting to see how this month ends.

February I've had 252 and 416 so that is a huge difference.

But as far as totals, in 2023 I had 6.8mwh and in 2024 I had 7.1mwh (those are my only full years of having solar).
