In my case with solar and ESS MY CONSUMPTION did not really change. From LADWP's view, a home that in 2020 consumed 28,000 kwh consumed 2,000 in 2021. For LADWP it was over 90% reduction. For me, no change in use at all.
How did you pull that off with so much coming from "self-gen"? I also have 3 PW's... and during all of 2021 they only exported 5,680 kWh. I was cycling them pretty hard too. My take from the grid was basically equal to what I exported in those 12 months.
Per Tesla's data for my house in 2021... Solar generated 13,100 kWh of which...
2,500 kWh was used contemporaneously in the home.
6,400 kWh was pushed into Powerwalls
4,200 kWh was pushed to the Grid.
About 10% of the 6,400 (640 kWh) that went into the Powerwalls was lost (but I did get a lot of wummm wummm wummm sounds).
So, I had 12,380 kWh of usable solar generation to divvy up.
My annual home consumption was about 12,380 kWh
2,500 kWh was used contemporaneously
5,680 kWh the aforementioned came out of the PWs after wummm wummm wummm
4,200 kWh came back from the grid
